Keeping a target color after adjusting opacity or alpha
by Jeff Kowalczyk 29 Nov '10

29 Nov '10

Color newbie: How do I keep a perceived color from changing when I add opacity? Is there a formula to use in RGBA space, or do one of the other color coordinate systems have this as one of their dimensions? I have a specific logo color #00538FFF that I'm using in other graphics. For these other graphics, I have a front layer with a rectangle fill of this color, opacity set the 80%. The desired effect is that photos in lower layers become visible but clearly tinted in the main color. The 80% opacity is clearly not a color match for the original RGBA #00538FFF, nor did I expect it would be. My question is: how do I calculate the matching color at a certain opacity? Thanks, Jeff P.S. I am using Inkscape bzr trunk. P.P.S. Apologies for not attaching an example, I have not been successful in attempts to subscribe to inkscape-users.

Drawing blury with the Calligraphic Pen Tool
by Mikael Ståldal 28 Nov '10

28 Nov '10

The Book Of Inkscape talks about drawing blury strokes with the Caligraphic Pen Tool. But how do you do that in a convenient way? I can't get it to remember the blur when drawing several strokes, so I end up having to set each stroke's blur manually. Is there a better way?

Inkscape needs your help!
by Ian Caldwell 27 Nov '10

27 Nov '10

hello, It's been a good long while since I've emailed the mailing list I am a part of the server management involving inkscape and have been for approximately 4+ years. I am writing you today for 2 reasons. 1. Our current site is terrible, I'm sorry but there is no chance of just brushing over it. I know there have been a fair number of people in the past 2 years who have submitted website mockup ideas and we've had contests but no one has ever followed through. Which I'll take partial blame for it. Things are just scattered every which way 2. I wanted to update you on the status of the Test suite, Osuosl is currently in the process of setting up the ability to run test suites so that we can test the SVG building more efficiently. So stay tuned for more info on this in the near future. Anyway back to problem 1. Here's how I think we can best solve this problem. We're going to break the website into different categories and duties. 1. UI (mockups) (*ARTIST*/PROGRAMMERS*) - Ability to make mockups of how you think the website should look. - After we pick yours we will request to see the top couple in HTML/CSS 2. Artwork for the website (*ARTIST*) - Ability to develop / sharpen logos as well as various buttons etc as needed 3. Drupal Modules (*PROGRAMMERS*) - Skills required - Knowledge of Mysql/PHP/JS and HTML - Knowledge or ability to learn how drupal works 4. Documentation (*WRITERS*) - Skills - Moderate knowledge and ability to update and port existing content over to the new site. 5. Translation - We need people who specialize in various languages to port content once completed into the various languages. So what's wrong with the current design? a lot, it's way too cluttered and disorganized not to mention you click wiki you go to a whole different navigation and sub site. That is just a pain to deal with as a user. So if you have skills in 1 of the above 5 categories, please contact me or the list directly and we'll assemble the a team and get this going! let me know what you think.... Thanks, Ian "Inc" C. P.S we've also started on a site map located here http://www.mindmeister.com/70256281/inkscape-web-site-frontpage Pw is: vectorfun

xml - path attribute (d)
by unknown＠example.com 26 Nov '10

26 Nov '10

Hello everyone, I'm trying to use Inkscape to digitalize a diagram of experimental data. This is how I went about it: 1) Get the page in the .pdf document that holds the diagram. 2) Print out this page to another .pdf document. 3) Import the .pdf of the diagram page into Inkscape (with the "fine" import precision). 4) Ungroup everything. 5) Cleanup the text so that it doesn't bother the page size - coordinatization. 6) Resize the page size to the diagram axis span. 7) Set the document units to 'mm'. 8) Draw a path along the line in the diagram. 9) Export the path node coordinates into a .txt, xml, or whatever file. Coordinate system is defined by the document metrics and the page (lower left corner is 0, as the border rules state). This is the .svg document in question: http://www.megaupload.com/?d=RZPI1084 Currently, I am stuck on the step 9 of the process. I have found the xml editor within Inkscape, but I haven't been able to find the option to export path data. The "d" attribute now holds values that are far to great to be in milimeters, although the document units are set in milimeters. There are letters like "M" (I believe it stands for "MOVE", I've played around with it) within the "d" attribute of the path. Is there a way to export just the paths I have drawn (I can give them sepparate id-s and names to distinguish them later on)? What is the best place to look for the description of the "d" attribute of a path? How do I sync the document units to the values of the d attribute? I have seen that there is a "transform" option in the xml property window of my path... what is that? Any advice would be greatly appreciated, Tomislav

PDF export error
by Matthew Beckler 16 Nov '10

16 Nov '10

Hello, Not sure how to describe this PDF export error, so I thought I'd check the list first. When I make a simple four node path in the attached SVG, the PDF export closes the path (test.pdf). Not sure if I'm doing something wrong here, so any input would be helpful. I get identical output whether I manually "Save As" PDF or convert it from the command line. Thanks in advance. I'm using a freshly installed copy of Ubuntu 10.10, with Inkscape 0.48.0 r9654. I can file a bug report if it's warranted. Thanks, Matthew

EPS Error

Hi, I got an error when I try to open a eps file that I create using Inkscape, I'm on windows XP. Actually I know the file is OK, because I converted to PDF and it looks nice. However, I cannot open it using GSview. Is it related to some problem on how GSview read the files? GSview 4.9 2007-11-18 GPL Ghostscript 8.70 (2009-07-31) Copyright (C) 2009 Artifex Software, Inc.
