call a Python And Gtk Executable (PAGE). Dependency information is in the "INSTALL" file. If you are reading this you likely already know. SVGpage is a pyGTK application to view and convert to and from vector (SVG) graphics. In addition to SVG files the application is able to open PNG, GIF, JPG (including Exif), BMP and XPM. It can save as SVG, PNG or JPG. If you are looking for an SVG editor capable of creating fine, crisp curves and gradients, you've got the wrong program. For simple graphics SVGpage can convert to SVG and render something very close. For involved images, like pictures, you wind up with a PAINTERLY EFFECT. This effect can be very distinctive and attractive and is sought after by many. Sort of a good, single-click "GIMPressionist." So if that's what you're looking for, you've found it. SVGpage can also take your SVG images and convert them to a PNG or a JPG. Even resize them. It uses Bilinear Interpolation and does an excellent job. My webite should have the latest version of this software as well as several other programs I have made and distribute as Open Source. My personal website is located at: http://www.pcbypaul.com This program and updates will be posted with other graphics-related software at: http://www.gimphelp.org """) msg2 = _(""" First, for my fellow geeks...I compiled autotrace with the following flags: --disable-shared --without-pstoedit --without-magick HEADS UP: if you are looking for an SVG editor capable of creating fine, crisp curves and gradients, you've got the wrong program. SVGs are just XML files with a whole bunch of math in them. In an editor's environment the points and curves are known and plotted with precice equations. IN CONTRAST to this, a utility like SVG-page/autotrace is taking an existing image and grabbing points and making controlled "best guess" estimates. What you end up with is, for simple graphics, something very close. For involved images, like pictures, you wind up with a PAINTERLY EFFECT. So if that's what you'd like, enjoy. As explanations for some of the possible parameter tweaks, below is the MAN page for autotrace. One tip -- by far the most influential parameter is the DESPECKLE-LEVEL. Use a low number for something simple or text, a higher number for pictures and such... SVG-page makes playing with these values simple. -------------------------------------------------------------------------------------- NAME autotrace - convert bit map image data to vector graphics SYNOPSIS autotrace [-background hexvalue] [-centerline] [-color-count int] [-corner-always-threshold angle] [-corner-surround int] [-corner- threshold angle] [-despeckle-level int] [-despeckle-tightness real] [-error-threshold real] [-filter-iterations int] [-help] [-input-for- mat format] [-line-reversion-threshold real] [-line-threshold real] [-list-input-formats] [-list-output-formats] [-log] [-output-file file] [-output-format format] [-remove-adjacent-corners] [-report- progress] [-tangent-surround int] [-version] inputfile DESCRIPTION The autotrace program accepts bitmap graphics from the file inputfile specified on the command line, and as output produces a collection of splines approximating the original image, the converting the image from bitmap to vector format. It behaves in a manner similar to the commer- cial software known as StreamLine (from Adobe Systems, Inc.). The result is sent to standard output unless the -output-file option is active. OPTIONS Options can begin with either -- or -. Any unambiguous abbreviation can be used for the option name. Option names and values can be sepa- rated with either a space or equal sign (=). -background-color hexvalue Employ the color specified by the hexadecimal code hexcode as the background that should be ignored, for example FFFFFF (default: no background color). -centerline Trace an object's centerline (default: employ its outline). -color-count int Reduce the bitmap to using the number of colors specified by the unsigned integer int (range: 1-256). The default value of 0 indicates that no color reduction is to be done. Does not work with grayscale images. -corner-always-threshold angle Consider any angle at a pixel which falls below the specified angle (in degrees) as a corner, even if it is bordered by other corner pixels (default: 60). -corner-surround int Consider the specified number of pixels on either side of a point when determining if that point is a corner (default: 4). -corner-threshold angle Consider any pixel which forms an angle with its predecessor(s) and successor(s) that is smaller than the specified angle (in degrees) as a corner (default: 100). Subdivide fitted curves that are offset by a number of pixels exceeding the specified real number (default: 2.0). -filter-iterations int Smooth the curve the specified number of times prior to fitting (default: 4). -help Print a help message and exit. -input-format format Employ the specified input format, where format is one of: BMP (Windows bitmap format) PBM (Portable BitMap format) PGM (Portable Graymap format) PNM (Portable Anymap format) PPM (Portable Pixmap format) TGA (Targa format) The supported input formats are determined when the application is built and depend upon the availability of other software (the -list-input-formats command can be used to determine which are supported locally). -line-reversion-threshold real When a spline is closer to a straight line than the specified real number weighted by the square of the curve length (default: .01), maintain it as a straight line, even if it is a list with curves. -line-threshold real If a spline does not deviate from the straight line defined by its endpoints by more than the specified number of pixels, then treat it as a straight line (default: 1). -list-input-formats Send a list of the supported input formats to stderr. -list-output-formats Send a list of the supported output formats to stderr. -log Send a detailed progress report to the file inputfile.log. -output-file file Send the output to the specified file. -output-format format Employ the specified output format, where format is one of: ai(Adobe Illustrator) cgm(Computer Graphics Metafile) eps(Encapsulated ) er(Elastic Reality Shape format) fig(xfig (1) 3.2) mif(FrameMaker MIF format) pdf(Portable Data Format) p2e(pstoedit (1) frontend) sk(Sketch) svg(Scalable Vector Graphics) swf(Shockwave Flash 3) The supported output formats are determined when the application is built and depend upon the availability of other software (the -list-output-formats command can be used to determine which are supported locally). -remove-adjacent-corners Remove adjacent corners. -report-progress Report tracing status in real time. -tangent-surround int Consider the specified number of points to either side of a point when computing the tangent at that point (default: 3). -version Print the version number of the program and exit. """) msg3 = _(""" You can use SVG-page as a simple image viewer that can render SVGs, but most will be using it to convert back and forth from raster(png, jpeg, etc) to SVG. It makes very nice quality rasters from SVGs. And as mentioned on the autotrace tab -- does OK with simple graphics to SVG, and makes what many find a desireable painterly effect from photos. Some examples are included in the distribution folder along with SVG-page. Check out what is there and play with thew settings to get a feel. A couple things to note: Starting with larger rasters will yield smoother curves and gradients when rendered as SVGs. Although this can vary with individual images, as well as the desired effect. To save time openning an external graphics editor all the time, there are "Save Half-Size" and "Save Double-Size" menu items which will alter the size of the displayed raster image (saved in a temporary file) -- so subsequent calls to "Render as SVG" will have a larger or smaller image to start with. If you are NOT interested in making SVGs with a painterly effect, then the suggestions for alternate editor programs include: Inkscape http://www.inkscape.org/ Sodipodi http://www.sodipodi.com/ Skencil http://www.nongnu.org/skencil/ """) msg4 = _(""" SVG-page will open JPG (including exif), PNG, BMP, GIF, XPM and SVG images.

Images are scaled into the appropriate viewing panel at a size no larger than 200x200 pixels. If you wish to see the "real"image, that is, full-scale, then simple use the: View -> Full-Size PNG or View -> Full-Size SVG Any raster type will be opened in a separate window with the "Full-Size PNG" menu. If it is too big for the screen the opened window will have scrollbars to make things more convenient. Same goes for SVGs. You can double or half the size of Raster images with: Save -> Raster Half-Size or Save -> Raster Double-Size The resized image is saved into a temporary file. Always as a PNG. This eases some possible later rendering actions, so the menu was titled PNG to reflect this fact, but you may also save it as a JPG. The listing is under: Save -> save Raster -> Save As... """) msg5 = _(""" Rendering is accomplished via autotrace. Simply click the: "Render As SVG" button And the currently displayed raster image will be converted to an SVG. There is a whole column of parameters you can play with to influence the output of the rendering. The most common general setings are already the defaults. The most dramatic setting is on the top of the parameter list at the far right of the main window -- DESPECKLE LEVEL. The Full-Size of the original raster image can affect the quality and "smoothness" of the resulting SVG. This is most noticeable with gradients and curves. For an example, try rendering "circles200.png" and also try "circles." Circles is a much larger image, and the resulting SVGs are quite different. The smaller image rendered looks very "broken up", while the larger image rendered looks very close to the original. If tweaking the render parametersw is giving you an image that is too choppy -- try saving double-size and then render. Or save double-size a couple times.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.
