website update - svn lock
by Alexandre Prokoudine 02 Nov '07

02 Nov '07

Hi, Not sure this is the right list to write, but since about a week we've been experiencing problems with updating web-site using the publishing script: it complains about svn lock. This makes it impossible to make things like translated news available to visitors. Could this please be fixed? Alexandre

Windows developers beware!
by unknown＠example.com 02 Nov '07

02 Nov '07

Bob just changed building on Windows to default to dwarf2 things. This means that you should probably do the following if you hadn't already: 1. download the latest libpackage from inkscape.modevia.com http://inkscape.modevia.com/win32libs/devlibs-2.12-071101.7z 2. NOTE THE NEW c:\devlibs DEFAULT PATH FOR THE DEV LIBS!!! 3. see mingwenv.bat and build.xml to make sure the paths are correct 4. btool clean, and start using build.xml again (default) Hope you have no probs!

Some how this time it seem reversed, and the work isn't even close to being done. I think the going trend right now is the the set we have could be updated to be tango styled. I wouldn't give up just work on make things better. Joshua L.

Draft Filter Effects Chapter for Inkscape Guide
by Tavmjong Bah 31 Oct '07

31 Oct '07

Hi, I've put a draft of the Filter Effects chapter for an update to my book at: http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Filters_0.46.html Hopefully this will generate some interest in using the filters and result in better testing. And it would be great if it motivated somebody to complete the Image filter primitive which would be very useful. If you are interested in comparing Inkscape rendering to your favorite browser's rendering, you can find web pages with Inkscape png and svg files starting at: http://tavmjong.free.fr/INKSCAPE/MANUAL/images/FILTERS/index.xml Happy Filtering, Tav

[Fwd: cairo snapshot 1.5.2 now available]
by Ted Gould 31 Oct '07

31 Oct '07

FYI -------- Forwarded Message -------- From: Carl Worth <cworth@...573...> To: cairo-announce@...278... Cc: gnome-announce-list@...45... Subject: cairo snapshot 1.5.2 now available Date: Tue, 30 Oct 2007 22:47:52 -0700 A new cairo snapshot 1.5.2 is now available from: http://cairographics.org/snapshots/cairo-1.5.2.tar.gz which can be verified with: http://cairographics.org/snapshots/cairo-1.5.2.tar.gz.sha1 39d6593433ce4896a065a6c4ad2882a5cc1fe05a cairo-1.5.2.tar.gz http://cairographics.org/snapshots/cairo-1.5.2.tar.gz.sha1.asc (signed by Carl Worth) Additionally, a git clone of the source tree: git clone git://git.cairographics.org/git/cairo will include a signed 1.5.2 tag which points to a commit named: ee5dc04aaf81d6ce9c496c7966ceebfbd6ab12fb which can be verified with: git verify-tag 1.5.2 and can be checked out with a command such as: git checkout -b build 1.5.2 This is the first snapshot in cairo's unstable 1.5 series. It comes 4 months after the 1.4.10 release. This snapshot includes significant improvements to PDF and PostScript output, which is one of the things in which we're most interested in getting feedback. There are a couple of minor API additions, and several optimizations, (primarily in the "print/vector" backends). And there are dozens of bug fixes and robustness improvements. NOTE: This is a snapshot of in-progress development, not a "release". So it is expected that there will be more rough edges than one would find in a major release. For example, various tests in the test suite are currently failing against the PDF backend, and we'll get those fixed before the 1.6 release. But you're likely to notice more improvements than problems, so give this snapshot a try and let us know how it goes for you. Read more below for many details on the exciting things in cairo 1.5.2 compared to cairo 1.4.10. Have fun with cairo! -Carl New dependency on external pixman library ----------------------------------------- A significant change in this snapshot compared to all previous cairo releases is that cairo now depends on an external "pixman" library for its software rendering. Previously this same code was compiled internally as part of cairo, but now the code is separate so that both cairo and the X server can now share common code, (thanks very much to Søren Sandmann for his work on separating pixman and maintaining it). So users will need to acquire and build pixman before being able to build cairo. The current release is 0.9.6 and can be obtained from here: http://cairographics.org/releases/pixman-0.9.6.tar.gz which can be verified with: http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1 66f01a682c64403a3d7a855ba5aa609ed93bcb9e pixman-0.9.6.tar.gz http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1.asc (signed by Carl Worth) Major PDF/PostScript improvements --------------------------------- Adrian Johnson has done some long-awaited work to make cairo's PDF and PostScript output more interesting than ever before. First, many operations that previously triggered image fallbacks will now be rendered as native vectors. These operations include: PDF: cairo_push_group, cairo_surface_create_similar, cairo_mask, A8/A1 surface sources, repeating/reflecting linear gradients. PostScript: cairo_push_group, cairo_surface_create_similar, gradients, bilevel alpha masks, (for example, all values either 0 or 255 for an A8 mask). Not only that, but when an image fallback is required, it will now be limited to only the necessary region. For example, a tiny translucent image overlaying a small portion of text would previously caused an entire PostScript page to be rendered as a giant image. Now, the majority of that page will be nice text, and there will only be a tiny image in the output. Additionally, the PostScript output now carefully encodes text so that if it is subsequently converted to PDF, the text will be selectable. This is very exciting progress, and we're hoping to hear from users during the 1.5 series about how things have improved, (for example, inkscape users doing cairo-based PDF export: please let us know how things look). And feel free to pass your thanks along to Adrian for his excellent work. NOTE: This much improved PDF output makes more sophisticated use of functionality in the PDF specification. This means that cairo's output will sometimes expose bugs in some free software PDF viewers, (evince, poppler, and xpdf, for example), that are not yet ready for such PDF files. We're working with the poppler maintainers to get these bugs fixed as quickly as possible. In the meantime, please double-check with other PDF viewers if cairo-generated PDF files are not being rendered correctly. It may be due to a bug in the viewer rather than in the PDF file that cairo has created. Robustness improvements ----------------------- Chris Wilson has made the largest contribution by far to cairo 1.5.2, (in number of commits). His more than 150 commits include a huge number of fixes to increase cairo's robustness. These fixes make cairo more robust against invalid and degenerate input, (NaN, empty path, etc.), against size-0 malloc calls, against memory leaks on error-recovery paths, and against other failures during error handling. He also implemented atomic operations to cairo, and used them to fix cairo's previously non-thread-safe reference counting, again improving robustness. Chris has put a tremendous amount of time and effort into writing analysis tools for this work, and in running those tools and fixing the problems they report. We're very grateful for this work, and hope that all cairo users appreciate the more robust implementation that results from it. This work is largely thankless, so it might make sense to notice sometime that cairo has been running quite smoothly for you, and when you do, send a quick "thank you" off to Chris Wilson, since it is all definitely running smoother thanks to his work. New API ------- There are no major additions to cairo's core API. The only new, generic functions are: void cairo_surface_copy_page (cairo_surface_t *surface); void cairo_surface_show_page (cairo_surface_t *surface); which can now be used much more conveniently than the existing cairo_copy_page and cairo_show_page functions in some situations. These functions act identically, but require only a cairo_surface_t* and not a cairo_t*. All other API additions are specific to particular backends. New cairo-win32 API (new font face function and "win32 printing" surface) ------------------------------------------------------------------------- There is a new function for creating a win32 font face for both a logfontw and an hfont together. This complements the existing functions for creating a font face from one or the other: cairo_font_face_t * cairo_win32_font_face_create_for_logfontw_hfont (LOGFONTW *logfont, HFONT font); There is also a new "win32 printing" surface: cairo_surface_t * cairo_win32_printing_surface_create (HDC hdc); This interface looks identical to the original cairo_win32_surface_create, (both accept and HDC), but the behavior of this new surface is very different. It should only be called with a printing DC, and will result in all drawing commands being stored into a meta-surface and emitted after each page is complete, with analysis to do as minimal image-based fallbacks as necessary. The behavior and implementation shares much with the PDF and PostScript backends. New cairo-ps API (EPS and PostScript level control) --------------------------------------------------- An often requested feature has been the ability to generate Encapsulated PostScript (EPS) with cairo. We have that now with the following very simple API. Just do cairo_ps_surface_create as usual then call this function with a true value: void cairo_ps_surface_set_eps (cairo_surface_t *surface, cairo_bool_t eps); [NOTE: As always with snapshots, it's possible---though not very likely---that the API could still be modified before a final release. For example, this is the first public cairo function that accepts a Boolean parameter. I'm generally opposed to Boolean parameters, but this is probably the one case where I'm willing to accept one, (namely a "set" function that accepts a single Boolean).] Also, it is now possible to control what PostScript level to target, (either level 2 or level 3), with the following new API: typedef enum _cairo_ps_level { CAIRO_PS_LEVEL_2, CAIRO_PS_LEVEL_3 } cairo_ps_level_t; void cairo_ps_surface_restrict_to_level (cairo_surface_t *surface, cairo_ps_level_t level); void cairo_ps_get_levels (cairo_ps_level_t const **levels, int *num_levels); const char * cairo_ps_level_to_string (cairo_ps_level_t level); Improvement for cairo-quartz ---------------------------- Brian Ewins had contributed several improvements to cairo-quartz. These include an implementation of EXTEND_NONE for linear and radial gradients, (so this extend mode will no longer trigger image fallbacks for these gradients), as well as native surface-mask clipping, (only on OS X 10.4+ where the CGContextClipToMask function is available). He also fixed a semantic mismatch between cairo and quartz for dashing with an odd number of entries in the dash array. We're grateful for Brian since not many quartz-specific improvements to cairo would be happening without him. Optimizations ------------- Optimize SVG output for when the same path is both filled and stroked, and avoid unnecessary identity matrix in SVG output. (Emmanuel Pacaud). Optimize PS output to take less space (Ken Herron). Make PS output more compliant with DSC recommendations (avoid initclip and copy_page) (Adrian Johnson). Make PDF output more compact (Adrian Johnson). Release glyph surfaces after uploading them to the X server, (should save some memory for many xlib-using cairo application). (Behdad Esfahbod). Optimize cairo-win32 to use fewer GDI objects (Vladimir Vukicevic). win32-printing: Avoid falling back to images when alpha == 255 everywhere. (Adrian Johnson). win32-printing: Avoid falling back for cairo_push_group and cairo_surface_create_similar. (Adrian Johnson) Bug fixes --------- Avoid potential integer overflows when allocating large buffers (Vladimir Vukicevic). Preparations to allow the 16.16 fixed-point format to change to 24.8 (Vladimir Vukicevic). Fix bugs for unsupported X server visuals (rgb565, rgb555, bgr888, and abgr8888). (Carl Worth and Vladimir Vukicevic) Fix bugs in PDF gradients (Adrian Johnson). Fix cairo-xlib to build without requiring Xrender header files (Behdad Esfahbod). Make cairo more resilient in the case of glyphs not being available in the current font. (Behdad Esfahbod) Prevent crashes when both atsui and ft font backends are compiled in (Brian Ewins). Make font subsetting code more robust against fonts that don't include optional tables (Adrian Johnson). Fix CFF subsetting bug, (which manifested by generating PDF files that Apple's Preview viewer could not read) (Adrian Johnson). Fixed error handling for quartz and ATSUI backends (Brian Ewins). Avoid rounding problems by pre-transforming to avoid integer-only restrictions on transformation in GDI (Adrian Johnson). Fixed an obscure bug (#7245) computing extents for some stroked paths (Carl Worth). Fix crashes due to extreme transformation of the pen, (seems to show up in many .swf files for some reason) (Carl Worth). Fix glyph rendering when using a bitmap strike with a scaling-only transformation (Keith Packard).

Methods for drawing circular handles and selection cues
by Gerrit . 31 Oct '07

31 Oct '07

Hello everyone! I am looking for the methods that draw little circular handles and selection cues respectively. Does anyone know these? I am making extensive use of SVG group nodes. I would like to be able to check where the center of an object is, in order to know if I previously changed the group matrix or the content's matrices. I found no way to easily check this in Inkscape. It is especially difficult to notice if a path object is changed or moved. I found that the default behaviour for dragging a path is that the path data gets altered, instead of applying a translation matrix. I plan to use the graphics as animation assets, so the difference matters to me. What I would like to do now is to make code modifications to draw a little circle at the center of a selected object, so I can clearly see when the contents or the path are off center. Can someone maybe help me and point me to the relevant classes and methods? I searched the source code and the mailing list archives, but without luck so far. I need: 1. The method that draws those little white circles, e.g. at the end of Bezier handles. 2. The method that draws a bounding box and the selection cue whenever an object gets selected, so that I can apply the circle. Many thanks in advance!

libspiro

Hi, FYI :-) Forwarded Conversation Subject: [Fontforge-devel] libspiro From: George Williams <gww@...1824...> To: fontforge-devel(a)lists.sourceforge.net There is now a separate project http://libspiro.sf.net It contains the source code for the spiro library under svn (not cvs!). The ffspiro subdirectory of the fontforge project has been removed. FontForge's configure script has been tweaked to look for libspiro. I hope this will be last major change in this area. I need to: Post some docs so other people (InkScape, etc.) can use libspiro too Wait a little bit and see if it works for other people before posting some libspiro releases. (I should add that these sources are based on Raph's updated work in his garden rather than the released tarball -- there's a shell script to grab current stuff from the garden included in the svn repository).

Pressing Alt means "do nothing"; this allows you to move the mouse, without releasing, to a more convenient place from where to continue tweaking the color after letting go of Alt. As with the other modifiers, releasing Alt temporarily redefines the zero-change axis to go through the point where Alt was released. For example, imagine you made your color darker by Ctrl+dragging towards the bottom edge of the window and you now need to make it less saturated. You cannot however Shift+drag it any lower because there's just not enough room for that. In that situation, without releasing the mouse, Alt+drag it upwards to a convenient spot and then Shift+drag downwards as needed. Also, you can start dragging from the swatch with Alt pressed to avoid changing the color while you take a more convenient position for adjustments. -- bulia byak Inkscape.
