Re: [Inkscape-devel] Rendering problem for an object with blur / 0.46 Official vs 209225 vs 20967

Hi, I'll try to explain better what I mean with a new screenshot: http://www.corpsmoderne.net/~eve97/vertex/rocket_bug/display_inkscape_046_v… First, I'd like to state a few things: - I'm not an artist, but I draw things in Inkscape, and I draw them in SVG to have them displayed as SVG. So my "visual perception" of SVG is what Inkscape shows to me, not a PNG (which I often not even generate). It means I design the object *as I see it rendered on Inkscape canvas*. - I have several drawings made with 0.46 or previous versions of Inkscape, and there are many places where I could download SVG designed with that (openclipart, etc.) So, let's take the following hypothesis: - After seeing a nice SVG in my browser, I download or open in Inkscape 0.47 a file which was drawn with a previous 0.46 version, in order to use it as a clipart, or to rework on it. On the top of the screenshot, it is a shape drawn in Inkscape 0.46, with filter quality set to average (default). It is what I see in my browser, or on the PNG if I generate it. My 0.47 Inkscape is set to default for both Blur display and Filter display, as I have a small machine (512Mb memory, Intel Pentium III mobile, 1133Mhz). I open the file, and I see what shows at the bottom of the screenshot. I hope you'll admit that it is awful and doesn't look like at all what shows in my browser. BUT it is what I work on, I have no other way to work on SVG. I'm not switching back and forth to PNG or to the browser to check what it looks like there. What am I supposed to do at this point? Remember, I'm an average user, not knowning the Inkscape internals. A) I say: this Inkscape program is mad, I'm not going to use it. I close it, end of story. B) I could try to change the blur quality and/or the filter quality to better or best. OK, I do that. But the problem is, the canvas is not updated when I do that, and it's a general preference, not a per-document preference. So, first, I'll have to: - with my document still opened, change the Blur / Filter effect and see that what is displayed on canvas has not changed. - close the document and Inkscape, reopen Inkscape which now has Blur and Filter set to better or best, and see that the file looks like what it should. (or something similar, because I have no idea of the exact real value of the quality). SO: setting the displays to a "lower" average quality in Inkscape 0.47 than in Inkscape 0.46, which was supposed to be intentional to help the designer (the designer in Inkscape 0.47) conserve CPU, results in fact in obliging me (who opened on older file) to set Inkscape to high quality, for all my documents. And I have a small machine - I can't afford to do that. C) I could just do what I was adviced to in the channel: remove the filters on the object. This means I need to find all objects with blur/filter, one by one, and remove that. After such a tedious task, then I lose the original information (here, the blur was 0.3), meaning I am absolutely unable to re-create or re-see the original file, as the artist designed it. What am I supposed to do now? For all the reasons explained above, I think that, although done with the best intention, the fact that the blur/filter display "average quality" has changed results in the opposite effect as the one intended. It seems to me that, at the moment, there are more SVG "done with 0.46" than "done with O.47', and that the case I am describing will arrive for a long, long time... If I missed an obvious point, I'd very much like to hear it.

GSOC: Interested in joining Inkscape
by sonali mendis 29 Mar '09

29 Mar '09

Hi, I'm Sonali Mendis from University of Moratuwa, Sri Lanka. I went through the project ideas listed at Inkscape page and I think it is a great project of my interest. I'm a graphic designer plus a developer and I think and I want to add my ideas and effort to improve this open source project. While using Inkscape, I thought *Guide Improvement *is essentially needed. In addition to that I have another my own idea of introducing different brush types with ability to increase and decrease the size by click of a key while drawing to the pencil tool and introduce an eraser tool with the same options. I need your kind feed back on the ideas mentioned above to select one which will benefit the Inkscape most. Thanking You, Regards, Sonali Mendis

Blurry Icons Problem on OSX
by André Berg 29 Mar '09

29 Mar '09

Hi, In the latest build from source on OSX (rev 21007) 95% of all user interface icons continue to be totally blurred. I submitted a screenshot in an earlier thread which, if it interests you, can be viewed here: http://img102.imageshack.us/img102/9260/inkscape20798osx105inte.png I understand that this is probably not at the top of the priority list. On that end, I would like to just ask two questions: 1. Is this normal for the current OSX builds or is this tied to my environment only? 2. Is there something I can do to revert back to rev. (approx) 20600 behaviour? At least until this has been fixed. As I understand, the icon engine was radically changed. Thank you very much for reading! André

[GSoC] kidscape and NFT dialog ideas!
by Jesus Mager 27 Mar '09

27 Mar '09

HI! My name is Jesus Mager. I am Computer Science Student in Mexico, and I wanna apply in this GSoC for Inskape. But I cant decide what idea I will choose to work on. May be the list can help me: Kidscape I was working with kids software, so: The kid-version of inkscape is a real important idea in the idea list so i con work on it? (In blueprint ti appear as a low priority) If yes: should it be a independent branch of the project, may be a separate project or should it be a option in the same inkscape. (I think the first is the best) The idea is make it for kids in what sense: easier, fashionable, lighter?? I saw the possible GUI: It only seems to do it for netbooks, and lighter platforms. But if the main idea is make it for kids: what about make a cooler kid-friendly interface... may be like tuxpaint (www.tuxpaint.org)? Any idea? New From Template dialog Is it a better option than kidscape? Should it only be the interface, or may be also a guitool to make new templates (dynamical)?? I hope you can give me a orientation to find the appropriate idea and clarify my questions. Bests Jesus Mager

Rendering problem for an object with blur / 0.46 Official vs 209225 vs 20967
by worms invasion 27 Mar '09

27 Mar '09

Hello, I have opened a file which I had done originally with 0.45.1 with the latest win32 snapshot (rev 20967) and there is a problem of rendering in Inkscape. The most obvious object is a simple object with fill and stroke solid colours, and a blur of 0.3. You'll find, for each version that I tested: - the object extracted from the original file, in svg - a screenshot of the rendering in the chosen Inkscape verion - the PNG exported by the said version. In all three versions, the filters/blur parameters were set to average (the default). I'll put them on my server so everyone can see the differences. There is also a zip of the 9 files to download. In short: the exported PNG appears correct in the three versions, but the screenshots of the rendering in Inkscape look very (or very) different across versions. The file looks absolutely normal, as I draw it, in 0.46 official. In r20225, the object is already badly rendered in Inkscape. In r20967, it's awful... How will the user figure out what do draw, or what will happen when a file made with 0.46 will be opened in a later version? Which one is correct to draw?

Logo for SVG Open 2009
by Jon A. Cruz 26 Mar '09

26 Mar '09

Hello all, I just wanted to put out that SVG Open 2009 is looking for header graphics for their new website... which is about to go live. SVG Open 2008 had a subtle header with outlines of the castles in Nuremberg, so is probably not good for this year's conference in California. If anyone is interested, this is a great opportunity to showcase both SVG and Inkscape. I believe that the site will be able to serve SVG directly for browsers that support it.

Filters zoom problem solved

While cleaning up the filters from unuseful primitives I removed some blur redundanceswhich caused that some Bevel filters display badly at full page zoom. I commited the file some minutes ago. ivan
