Max value for colors < 255

Hi, I have GTK+ 2.13.6, and had problems compiling Inkscape 0.46, until I found this patch http://launchpadlibrarian.net/15113774/gtk-clist.patch. Inkscape compiled pretty well, but now the color values are gone wild :-P I can't raise any of the color components more than 245. Even the default colors (in the color bar) are semi transparents (the alpha channel is at 245). I can write the HTML color "FF0000FF", and then the drawing turns solid red. But in the "fill and border" pannel, the values are at 245 (for red and alpha). If I try to change one of those values, they return to theier "correct" values (254), the image turns transparent again, and the HTML color shows "F50000F5". Here is a screenshot: http://drmad.org/inkscape-245-problem.png I've work with Inkscape 0.46 with a older GTK version without any problem. Help :( -- Oliver Etchebarne Bejarano drmad/paperclip http://www.paperclip.com.pe/

I think the .eps output is working well, unless someone else objects. https://bugs.launchpad.net/inkscape/+bug/168411/comments/20 Alvin

Microsoft Expression uses a profile shape method that is just like what Bulia suggested. The width equals the path length and the nodes along the profile shape equal the distance away from the centerline for the brush object's width. The LPE could be given three pieces of information... bottom most item is the stroke path, then brush object and then the profile path. If no profile path is selected, then the brush object is drawn along the stroke path without any change in brush width. ----- Original Message ---- Message: 2 Date: Wed, 03 Sep 2008 20:15:14 +0200 From: Maximilian Albert <Anhalter42@...173...> Subject: Re: [Inkscape-devel] "Live Pen" Feature Bounty To: bulia byak <buliabyak@...400...> Cc: inkscape-devel(a)lists.sourceforge.net, J.B.C.Engelen@...1578...

Since I had something like Pajarico's other suggestion in mind (see different email), I was thinking about how to store per-node information. But separating the width info from nodes and storing it in the described way will make the LPE very powerful and flexible. >> And finally, for the actual profile shape I think we should use a >> Spiro path for extra smoothness and natural flow.

"Live Pen" Feature Bounty
by Dave Crossland 04 Sep '08

Hi, I know Bryce has blogged about the annoyance of offering to fund development instead of contributing code, but if any developers are interested in Inkscape work for hire, I'd welcome the opportunity to commission the kind of feature seen in the LivePen Illustator plugin from http://01-lab.com in Inkscape :-) -- Regards, Dave

Could something like Microsoft's Expression live vector brush effects be created for Inkscape's LPE? If you have not seen what it does, Expression allows you to create a path and stroke the path using another object where the width of the stroke along the path is based on an contour path (think XY chart) where the width (X) is the location along the path to be stroked and the height (Y) is the width of the stroke at the point along the path. Ideally, the stroke object could be made up of multiple paths with various characteristics. For instance, you could create a stroke object that mimics a water color brush stroke. - Tony

question regarding wishblade robocraft support...
by stuart 03 Sep '08

03 Sep '08

Sorry for posting here if the user list if better. And sorry about the subject if it has been talked about before. I couldn't get sourceforge to add me to the inkscape user mail list and sourceforge was timing out on all my archive searches with no results. --- I remember reading that there was a patch or something to inkscape to support wishblade and robocraft users. Has that been integrated into the inkscape application? Is that what the DXF is all about? Wishblade users can not use DXF directly (needing the robocraft software to import DXF and change it to some sort of native (and maybe proprietary) GSD). Is there a way to get inkscape to save images in GSD in order to simplify the process? Ideally, I would prefer to skip bringing up the wishblade application. In my set up, I do all my work in linux (GIMP/INKSCAPE) and only the plotting in Windows. If I could do everything in linux it would simplify the flow of work greatly. Has anyone figured out how the craftrobo is communicated to in order to use it with common open source linux plotting software? Better yet, has anyone figured out how the wishblade has been crippled in order to use it with common open source linux plotting software? ...thanks

sorting out PS/EPS/PDF export mess
by bulia byak 03 Sep '08

03 Sep '08

It's always bad when the UI offers two ways to do the same thing without really explaining what's the difference. It's equally bad when UI uses some meaningless techno jargon such as "cairo" :) Unfortunately 0.46 was released still in the middle of a transition period which made both these evils inevitable. Now that we're in 0.47, however, I would like to address this issue by switching all of PS, EPS, and PDF output to cairo, removing the builtin Inkscape exporter, and purging the mentions of "cairo" from the UI. As a matter of fact, this has already partially happened (not sure who did this). Right now both PS export options work via cairo and produce identical output. The Inkscape-native PDF export is nowhere to be seen. The only exporter which still uses native code is EPS. However, since 1.5.2 cairo can produce EPS files too, so this can all be done in one place now (closng several EPS export bugs along the way). The only downside is that it will require cairo >= 1.5.2, is everyone OK with that? By the way, the latest cairo 1.5.12 finally fixes the bug where zooming in too closely in Outline mode produced messy broken lines. Now everything is neat and clean. Upgrade is recommended. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

LPE tool
by Alexandre Prokoudine 02 Sep '08

02 Sep '08

Hi, Honestly, I'm as much happy as much puzzled about the new tool called LPE tool. All across source code it is called an LPE tool, which probably means it's supposed to do editing of LPE params on canvas or draw LPE. It does both, but is restricted to geometric constructions only (and not all of them), which is why it probably has a "Create geometry constructions" tooltip. So the question is conceptual: is it supposed to do more than it does now and cover all possible LPEs or is it only geometry constructions related? Alexandre

new tool - lattice deformation
by ryrych＠...400... 01 Sep '08

01 Sep '08

hi! In latest revisions a new LPE effect appeared - Lattice deformation. But it hasn't been working properly these days. I propose to create a new tool - exactly Lattice deformation. This tool (idea) is in Adobe Photoshop. This tool would be very helpful. Currently we can bend a shape in a few way, but only in one direction. This tool would enable to bend the shape in many directions. Have a look at my image: http://img233.imageshack.us/img233/8486/siatkasn2.png I want to show a shape which is bent from top and bottom but I couldn't do it in Inkscape but I hope you know what I talking about - plaese see Everest logo: http://www.lackenbach.com/Images/Newsletter2000/Everlast.gif What do you thing about it? regards, Wojciech RRH Ryrych ps. sorry for my English
