crash on save as .ps or eps and convert filtereffects to bitmap

[theAdib]

When I export the file filters.svg to eps or ps (using the cairo exporter) Inkscape chrashes.
You have to switch on: filtereffects to bitmap (I have 90DPI)

Inkscape consumes a lot of memory and run out of new memspace.

running Win32 nightly build from Sept 16, I get the attached crash message :

[Thomas Hicks (hicks-kingtom)]

Th problem seems to stem form the fact that the svg file has two <svg> elements in it, and inkscape gets confused while working out the bounding box of the objects in the inner svg element

- correct bounding box if inner test case is removed form the file and tested separately
-correct bounding box if inner <svg></svg> elements are removed or replaced with <g> (although the size changes)

-problem remains if the filter effect is removed but made worse by filter effect dimensions (problems with interacting with viewbox???)

[Alvin Penner (apenner)]

just confirming that in Inkscape this file contains a box whose width is reported as 83121.75 px and height is 18884.25 px.

[theAdib (theadib)]

I commited a patch in svn rev 21327 that Inkscape does not crash any more.
Adib.

Still crashing on Ubuntu 9.04
when I use 300 dpi it calculates=277037 and height=62825 times 4byte results in 69619398100. This number is larger than 2^32=4294967296.
So we need to test here for possible range overflow.
patch #1 will check for possible overflow?field.comment=Still crashing on Ubuntu 9.04

[theAdib (theadib)]

attached patch (in addition to #6) calculates the bbox for absolute filtercoordinates. Now it renders the picture almost ok.

[theAdib (theadib)]

attached the pdf that shows how patch #7 works.

still to go: when I select the filtered element the bounding box shows somewhere else. Now on the top left corner.

Fix committed in 22391. I am closing this report Adib, please commit your other work when trunk opens back up to general development again.

[theAdib (theadib)]

as the issue is marked as released further development continues on this one : https://bugs.launchpad.net/inkscape/+bug/273767
