Macports has just gone up from boehmgc 6.8 to 7.0. I rebuilt inkscape and it's not starting up now. It just hangs in a gc call. Has anyone else tried with 7.0?

NEW: color gestures
by bulia byak 25 Oct '07

25 Oct '07

Color gestures A new method for quick and precise adjustment of colors is added in this version: color gestures. It works on the selected objects by grabbing the fill or stroke color swatch in the selected style indicator (on the left of the statusbar) and dragging it in various directions as described below. Note that this only works when the swatch displays a flat color; it does not work for a swatch showing "None", "N/A", or displaying a gradient (although you can select one or more gradient stops in Gradient tool and color-adjust them by color gestures just as you would do for objects). Color gestures can work on fill or stroke, depending on which swatch in the selected color indicator you drag. Color gestures work in HSL color space. Dragging without any keyboard modifiers adjusts the hue channel, dragging with Shift adjusts saturation, and dragging with Ctrl adjusts lightness. The adjustment is done by rotating the color swatch away from the original direction which is assumed to be NE at 45 degrees (i.e. from the swatch into the document window). That is, once you click and drag the color swatch, imagine a line going from the point where you clicked in the NE direction, across the entire Inkscape window. By dragging below or to the right of that line, you decrease the corresponding color channel, to the minimum at the lower edge of the window; by dragging it above or to the left, you increase it, to the maximum at the left edge of the window. If you hover your mouse exactly over the 45 degrees line, the change will be zero. Note that you can easily vary the precision of your adjustment. If you drag close enough to the swatch, each small movement results in a big change of the color. If you need a finer adjustment, just drag farther away from the swatch, towards the center of the Inkscape window or even to its upper right corner, where minute movements will produce very small changes in the color. In fact, this method gives you more color precision than even the color wheel in the Fill and Stroke dialog, unless you expand that dialog to fill the entire screen which is rarely practical. Watch the statusbar which will indicate, as you drag, the channel you are adjusting, the original value of that channel, and the new value. You can switch channels while you drag. That is, you don't need to restart dragging from the swatch if you want to adjust all three channels - you can do it in one drag, pressing and releasing Ctrl and Shift as necessary. Note that when you change the keyboard modifiers during drag, the position of the zero-change line is temporarily set to the current position of the mouse; this is done so that there are no sudden changes in color if you are switching modifiers away from the original 45-degree line. For example, you can select a green rectangle and first turn it into greenish-blue by dragging away from the Fill swatch and slightly above the 45 degrees line; then, without releasing the mouse, press Ctrl and drag a bit to the right to darken the color; then press Shift, release Ctrl, and adjust saturation. You can press or release Ctrl and Shift as many times as necessary during a single drag; when you are finally satisfied with your color, release the mouse to commit the change. Apart from precise adjustments, you can use color gestures to quickly perform common color transformations: * Ctrl+drag the swatch to the right and down to color all selected objects black. * Ctrl+drag the swatch upwards and to the left to color all selected objects white. * Shift+drag the swatch to the right and down to desaturate the color of selected objects. * Shift+drag the swatch upwards and to the left to maximize saturation of the color of selected objects. Note that when several objects or gradient stops with different colors are selected, the selected style indicator shows their averaged color. If you adjust that color by gesturing, the changed color will be assigned back to all selected objects/stops, in effect eliminating any difference between them. If you want to adjust many different-colored objects preserving their relative differences, use the color modes of the Tweak tool or color adjustment extension effects. This new technique requires some getting used to, but once you get the idea it is quite convenient, fast, and precise. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

Re: [Inkscape-devel] [Inkscape-user] Inkscape and DXF files?

Hi Aaron I will search the archives tonight as I have no way of contacting Kees. I think I might be able to write/modify a program to log serial/USB port activity on Windows computers. We could then translate the commands into a Linux program, this would give people the option to run the cutters from Linux. -Patrick Aaron Spike wrote: > Stéphane ANCELOT wrote: > >> The version you can find on my website is an enhanced version of the >> GSoC version dxf2svg. >> dxf2svg is GPL licensed , since I did not have had any answer from the >> author , I made available this slightly enhanced version through my website. >> However, you can copy and modify the above code (I wrote it, I grant you >> to do so ...). >> > > Patrick, > Sounds like you should start with this enhanced version rather than > backing up and working on the GSoC version.

cairo error in link phase
by Chris Lilley 25 Oct '07

25 Oct '07

Hello inkscape-devel, I'm getting an error building Inkscape svn, it fails in the link phase with an undefined symbol: In function `Inkscape::Extension::Internal::PdfImportDialog::_setPreviewPage(int)': /home/chris/inkscape/inkscape/src/extension/internal/pdfinput/pdf-input.cpp:544: undefined reference to `CairoOutputDev::setCairo(_cairo*)' Can anyone suggest what I am doing wrong? I just moved from Kubuntu 7.04 to Kubunti 7.10 and for various reasons its a clean install not an upgrade. Previously I had Inkscape building fine. I believe I have all the dependencies, since autogen and configure don't moan at me about anything. Attached is the relevant error. Happy to supply more details on request. -- Chris Lilley mailto:chris@...157... Interaction Domain Leader Co-Chair, W3C SVG Working Group W3C Graphics Activity Lead Co-Chair, W3C Hypertext CG

Roadmap 0.46
by unknown＠example.com 25 Oct '07

25 Oct '07

Looking at the roadmap of 0.46 I found: * (DONE) Convert use of gboolean to bool where feasible * (DONE) Switch from use of TRUE/FALSE to true/false When I search the source, I see *a lot* of gboolean and TRUE/FALSE. I will start switching code to bool when i see it. I could not find a text saying that we should use bool or gboolean. Similar issue is 'char' or 'gchar'. Where can I read which types to use? Thanks!

Yes. I thought about that too. But the only modifier left is Alt, and we'll again get an outcry of those who can't use Alt :) Still, since this is not such a crucial functionality, I think Alt is OK for that. -- bulia byak Inkscape.

Changing the names of a gradient.
by Ryan Lerch 25 Oct '07

25 Oct '07

As far as I can see, the only way to change a the name of a gradient is to do it in the XML editor. With the new on-canvas editing ability, would it be feasible to have the ability to change the name of the current gradient in the tool control bar for the gradient tool? If this is not a good place for it, where would be a better place? Cheers, ryanlerch

need help on filters
by Felipe Sanches 24 Oct '07

24 Oct '07

I would like to say that I am not much confortable with the filters implementation I was working on some time ago. I need help to make it work better. I know that there are bugs that are due to my incomplete broken implementation, but I am stuck because I still don't understand exactly how the filters infrastructure work I don't know how to properly implement zooming, nor rotation. Look at feturbulence. It does not rotate correctly. I also don't know whether I am using the best approach. I have used a pixmap buffer where I render the feturbulence effect and I have an "updated" flag. Then, if some parameters are changed (on sp-feturbulence.cpp) I set this flag to false. When the render method is called, it checks the updated flag and only recalculates the effect when the updated flag is false (and then sets it to true). When zooming, I will have to free the current pixmap buffer and create another one of greater size and recalculate it. It seems to me that zooming will have great slowdowns if I continue working that way. Any body know any kind of "design pattern" that I should be using to implement the zooming? I feel that I am walking the wrong way. And I keep scared about the possibility of not being able to fix these filters before next release deadline. So, what I mean is that I really need help to make this stuff work alright. Felipe Sanches, "JucaBlues"

Opacity Bug?
by microUgly 24 Oct '07

24 Oct '07

I found that a small bug in the Oct 18 build where the opacity for an object was incorrect. I had two object sharing the same gradient. One object was more opaque than the other even though the opacity for both was 100. I checked the XML editor and found that whilst both objects had Opacity:1, one of them had fill-opacity:0.71. I don't know how to reproduce this. It only happened once in an entire drawing. On a side note, I had been getting very confused when making a stop on a gradient transparent. I would change the Alpha value and the gradient would reflect the change, but later I would see the alpha value would be 255 instead of what I had set and what I saw on the graduent. It took me ages to spot that the alpha value was being replaced with the Master Opacity. Is this something that is still being worked on? -- View this message in context: http://www.nabble.com/Opacity-Bug--tf4664986.html#a13326117 Sent from the Inkscape - Dev mailing list archive at Nabble.com.

No autopackages of developer versions
by Rudekuvert 24 Oct '07

24 Oct '07

Hi From http://www.inkscape.org/download/ you can download Inkscape development versions. I can still get development versions for Windows that are only a few days old, but the latest autopackages for Linux is from 06-Sep-2007 12:02. Why? I'd like to test it on Linux. Best regards
