Gradient handle => Pattern handles?
by Alan Horkan 23 Feb '05

23 Feb '05

I was thinking how cool the gradient handles were and was wondering if it would be difficult to extend similar functionality to Patterns? (Should I file a request?) - Alan Horkan

Master Opacity and Marker question
by cedric 21 Feb '05

21 Feb '05

Hi, I'm back to User Manual. I 've been trying the Master Opacity, to explain its use. But when applied to Markers, only the path seems to be affected by the opacity changes. Is there another way to do ? PS to Bulia : Wonderful your new gradient handles !! -- Cedric ----------------------------- LISEZ -> SOS GIMP : http://www.le-radar.com/?mm/gimp mais aussi : http://wwww.le-radar.com http://www.cgemy.com

removing trivial wrappers
by Robert Crosbie 21 Feb '05

21 Feb '05

There are some wrappers that I'm not sure what to do with: This one below returns a value, but it is never checked. I assume a straight replacement is fine in this case and ignore the return value. inline unsigned int sp_repr_add_child(Inkscape::XML::Node *repr, Inkscape::XML::Node *child, Inkscape::XML::Node *ref) { repr->addChild(child, ref); return true; } There are others like this one below, where the value is actually checked somewhere. Should the ckeck be removed since it will always be true anyway? inline unsigned int sp_repr_remove_child(Inkscape::XML::Node *repr, Inkscape::XML::Node *child) { repr->removeChild(child); return true; } ... ok = sp_repr_remove_child (NODE_DATA (old_parent)->repr, NODE_DATA (node)->repr) && sp_repr_add_child (NODE_DATA (new_parent)->repr, NODE_DATA (node)->repr, ref); ... sp_repr_set_attr is another one that always returns true, but is used as a return value and in conditionals in a number of places. Should all instances of append_child be replaced with addChild? There are many, but it could be a Janitor item. void addChild(Inkscape::XML::Node *child, Inkscape::XML::Node *ref); void appendChild(Inkscape::XML::Node *child) { addChild(child, _last_child); } Cheers, -- Rob. http://woodpendant.com

NEW: on-canvas gradient editing
by bulia byak 21 Feb '05

21 Feb '05

Now in CVS: Gradient editing on canvas is now available, much more convenient and powerful than the old way of dragging gradient knots in the Fill&Stroke dialog. o Any number of selected objects can simultaneously display handles and direction lines for their linear and radial gradients (in the objects' fills or strokes). You can drag these handles directly in the drawing, to interactively adjust gradient positions. o Gradient handles can be enabled in the Node tool, shape tools, Text tool, and Dropper tool (on by default), as well as in Selector and Zoom tools (off by default). Use the Inkscape Preferences dialog to change this. o Any gradient handle, if dragged close to a handle of another gradient, will merge with that handle (drag with Shift to prevent merging). Dragging such a merged handle will adjust any number of gradients attached to it. To separate merged handles, drag them away one by one with Shift. o Radial gradients display handles in the center and at the ends of two radii, which allows you to move, rotate, squeeze, or stretch the gradient to form an arbitrary ellipse. Also, you can independently adjust the focus of the gradient; drag the central handle with Shift to separate the focus handle. o When dragged, handles will snap to the edges and the central axes of the bounding boxes of all selected objects (drag with Shift to prevent snapping). o Dragging with Ctrl will snap the angle of the linear or radial gradient to the user-settable angle increments (default is 15 degrees). The center of a radial gradient, dragged with Ctrl, will be constrained to horizontal and vertical movement relative to its previous position. When dragged with Ctrl+Alt, a handle moves along the gradient direction or its perpendiculars, allowing you e.g. to stretch or squeeze a linear gradient without disturbing its angle. Overall, this is a major usability milestone, something I dreamed to do since Sodipodi times. Gradients are one of the most widely used features in Inkscape, and now they are finally made usable (well, almost - see below). The old gradient position widget in Fill&stroke remains for now (and still works), but I plan to remove it as soon as the new on-canvas editing is sufficiently tested. I would welcome any feedback on the new feature. Next in my plans: A Gradient tool, which will allow you to actually create new gradients by dragging (at the moment you still need to open Fill&stroke to switch an object to gradient) as well as adjust most gradient settings in its controls bar at the top of the window. In that tool, the selected gradient handle will be moveable by arrow keys (with all the usual modifiers), and setting any color via Fill&stroke, palette, dropper, or Paste style will be applied to the selected handle's gradient stop (instead of the entire selected object).

Nightly build service statistics
by Mike Hearn 20 Feb '05

20 Feb '05

Hi, The nightly autopackage is currently being downloaded approximately 10 times per day, that is, there have been slightly more than 100 downloads in the past ten days. It's too bad the SF statistics system is offline at the moment, I'd be curious to know how many people were downloading the official packages. Oh well. thanks -mike

canvas border dropshadow
by Jakub Steiner 20 Feb '05

20 Feb '05

Hi there fellas! How would you feel about dropping the dropshadow for the document canvas border? It's visually distracting for small icons. While I'd like to have a very light outline to see where the edge is, I don't like the border taking too much attention away from the actual artwork and that's what happens thanks to its non-symmetric look. cheers -- Jakub Steiner <jimmac@...659...> Novell, Inc.

Hello! Thanks for the answer, but that did not work in the version I had used. I had just modified the generated postscript files instead.

OSX packaging
by Kees Cook 20 Feb '05

20 Feb '05

Well, with help from many people and activity on the IRC channel, I've blindly cobbled together some stuff for an OSX .app package. This basically works a lot like our Win32 package: all the libraries come along for the ride. (Which makes it giant: installed >100M, .dmg is 32M) New things in the CVS tree: - configure has --enable-osxapp which turns on my guesses at path locations in src/path-prefix.h - packaging/osx-app.sh attempts to create a .app package from a built inkscape - Info.plist is built from Info.plist.in. I have no idea if this file is valid. To compile inkscape on OSX, with modern fink, everything is available except gc 6.4. I updated the wiki here: http://www.inkscape.org/cgi-bin/wiki.pl?CompilingMacOsX I didn't get into the gc details, but if you build your own gc, and install it in ~/sw, you can build inkscape with: SW=~/sw export CPPFLAGS="-I$SW/include -I/sw/include" export LDFLAGS="-L$SW/include -L/sw/lib" ./configure --prefix=$SW After a "make install", you can build your Inkscape.app with: bash packaging/osx-app.sh Inkscape ~/sw/bin/inkscape Info.plist which should also build the Inkscape.dmg This is all completely untested. The only thing I know for sure is that the library resolution works right (I can run inkscape from the .app directory -- via command line). I have no idea what happens from within OSX itself (I'm ssh'd into a friend's machine). But I'm pretty sure whatever goes wrong can be fixed via src/path-prefix.h and Info.plist.in Good luck! I'm going to sleep! :) -- Kees Cook @outflux.net
