handling memory for display buffers
by bulia byak 15 Oct '06

15 Oct '06

Previously, Inkscape didn't check if there's enough free memory for its pixel buffers and could crash without warning due to insufficient memory, e.g. upon zooming in. This problem became much worse after implementing Gaussian blur, because rendering blurred objects at high zooms may require a pixel buffer much bigger than the visible canvas. Now this situation is handled more gracefully: if a display operation requires more memory than available, or more than 100Mb (which corresponds to a 5000x5000 pixel buffer), it is skipped. This may result in blurred objects "disappearing" at high zooms. This is purely a display issue, however, it never corrupts data; just zoom out (or reduce blur radius) and the missing object will show up OK. The "100Mb" magic number was chosen so that to prevent too large allocations which, even if they succeed, bog the system down to an almost unusable state. I realize it's far from perfect, but at least it's a solution which kinda works for a "typical" system with at least 256Mb memory. Any suggestions on how to better handle this are welcome. -- bulia byak Inkscape. Draw Freely. http://www.inkscape.org

inkscape.org server full
by Jon Phillips 15 Oct '06

15 Oct '06

Hello, now that I have access to our server, it looks like the server is full. Bryce, it looks like the /var/log/apache/ftp folder is 4 gigs of space. Seems like we shoudl unmerge apache-1.3 IMO and that ftp issue...looks like failed ftp attempts on there have mounted up over time... Anyway...I think this is causing the wiki issue and any php cookie issues on the site...(and is why I can't change some rewrite rules).

wiki error
by Jon Phillips 13 Oct '06

13 Oct '06

Hey all, I tried to save some non-english text onto our wiki and now am getting a db error: please see the wiki http://wiki.inkscape.org/ Bryce or ACSpike, could you restart the wiki please? This is weird that it can't take non-english text. I was trying to copy the language bar from the Open Clip Art Library... Please update..looks like the wiki is borked until it can be restarted...I hope we have backups as well in case we need to change things...otherwise, I think we could hand hack those fields in the db with non-english texts. Suck...maybe I can get some more powers on the server to do things...I can help fix this type of thing in seconds ;) I went onto the server and tried to refreshLinks.php in maintenance after this and here is the backtrace: Jon rejon@...1522... /home/inkscape/inkscape_web/wiki/maintenance $ php refreshLinks.php Refreshing link table.

metadata corruption

Whoever recently changed metadata or related code, please look into this bug: http://sourceforge.net/tracker/index.php?func=detail&aid=1575829&group_id=9… It's pretty bad because with it, setting metadata makes the file invalid and not loadable. -- bulia byak Inkscape.

Expanded alternative to normalized matrix file encoding
by Jonathan Shook 12 Oct '06

12 Oct '06

I like to use inkscape to build UI elements which I can access in raster form via a caching renderer. Typically, there are one or two aspects within the xml which I need to vary in order to get the dynamic effect I am looking for. I'll substitute values into the xml and render according to the request. Unfortunately, with the normalized matrix form being the final encoding, access to all of the basic transformations is cryptic. I would really like to be able to assign an id to an element, and access its discrete transforms individually, by type. For example, I would like to be able to render a watch into raster form by specifying a normalized rotation for hour, minute, and second. It would be pretty easy for me to do this now, only if I had the option of not collapsing the xml for transforms, and instead could access individual named or numbered transformations which constitute them, in addition to being able to access their high-level parameters, like "rotate by" instead of in affine form. Think of it as leaving procedural hooks for specialized renderings. Perhaps a property on a transform which indicates it should remain separate would suffice. Reactions?

Blur tips
by bulia byak 12 Oct '06

12 Oct '06

Some tips for using blur in Inkscape SVN: 0. Use the Blur slider in the Fill and Stroke dialog. You can blur anything - paths, shapes, strokes, calligraphy, bitmaps, text, clones, groups. 1. Currently, the maximum blur radius is 10% of the object size. Any larger blur will reveal the clear-cut margins - the blurred object cannot (currently) spread wider than the 10%. However it's easy to work around this limitation: group the object that you want to blur with some large fully-transparent object, thus making the group larger than the object, and blur the group. 2. Objects that store their transformation matrices (texts, groups, shapes, but not paths - unless you set "Store transforms" to "Preserved"), when scaled, scale also the blur applied to them. This means you can squeeze an object and its blur will be bigger in one dimension than the other. (It's also possible to do that by setting different blur radii for X and Y, but we don't yet have UI for that, though it works if you set it manually.) 3. You can combine blurring with gradients. For example, an ellipse with elliptic opacity gradient will look much softer and more natural when blurred. An object with a horizontal linear opacity gradient, when blurred, will look like it is more blurred on its transparent side than on its opaque side. 4. Masks and clipping are applied AFTER blur. That is, if you clip an object and then blur it (or blur it first and then clip - it makes no difference), the clipped edges will remain crisp. Often, this is what you want. If, however, you want to blur the clipped/masked edges too (possibly with a different radius), you can use grouping: group the clipped object with some other object (which you can then delete from the group) and blur the group. 5. A recipe for an autoupdating black drop shadow for object of any color: create object; unset its fill (it becomes black); create two clones of it; put one clone on top and paint any color; put the other color at bottom, blur it and shift sideways. Now you can edit the unset-fill original (use Alt+click to select it) and everything will update. Obviously, if you want a drop shadow of the same color as the object itself, just one clone for the shadow will suffice. 6. If an object has a fill that you don't want to blur (e.g. pattern, or if it's a bitmap), but you want to feather its edges, use blurred transparency mask: copy the object; paint it white; blur it as needed; scale the blurred copy down so its blur margins are entirely within the original object; select both the original and the blurred mask; do Object > Mask > Set. 7. You can use the Tile Clones dialog to create patterns of variously blurred clones - either with smooth variation of the blur per row/column, or/and with randomized blurring. -- bulia byak Inkscape.
