Export to PNG crashes at dpi > 150 [0.48.2 - Win7]

[Simone Bianchini]

Hello everyone and thanks in advance for your help.

I'm trying to export to PNG (at high dpi, I was actually aiming for 300) a huge composition with many objects comprised of thousands of nodes, the problem is that Inkscape just crashes everytime I prompt the exporting process.

I'm using Inkscape 0.48.2, Windows 7, 8 Gb of RAM an i5 2500k microprocessor and a 560 Ti graphic card.

I will attach the file that's causing me troubles as well (I just hope that you guys will be able to open it correctly without the gradients filters files, just let me know if it won't work).

by the way, the gradients should look like this (although the image in the linked file is slightly different):

Could you please explain what "gradient filter files" would be? Note: the filter definitions of applied filter effects are stored within each SVG file, even if you applied them from custom predefined effects (e.g. made available in menu 'Filters > Personal', or copy&pasted from another file).

AFAICT based on the naming of the custom filter effects and the looks of the drawing, it makes use of the sample filter effects provided by Ivan Louette in this InkscapeForum topic:

@Alvin or @JazzyNico - could one of you confirm this with a recent development build on Windows?

[Alvin Penner (apenner)]

crash confirmed on Windows 7, Inkscape 0.48.3
- at 90 dpi I get the below warnings, but also got a .png file size = 836K
- at 300 dpi I get an immediate crash with the memory allocation error below.

<off-topic>
The original SVG file has a huge amount of unused resources (mostly gradients) in the <defs> section (use 'File > Vacuum defs' to clean them up), and two hidden parts (resulting from hidden layers of imported drawings which are not visible).

After cleaning up the file (defs, deleting the stuff which is hidden anyway (with help of 'Edit > XML Editor')), the file size is reduced to 211'841 Bytes (from 2'134'770 Bytes), which does lower the initial memory footprint of the file at least a bit.

> New → Confirmed

@Alvin - I could already have confirmed the crash with stable Inkscape (see comment #4): the real question is whether current trunk with the new renderer and the updated devlibs still immediately crashes on Windows when trying to export at a higher resolution (300 dpi), or whether the report can be set to status 'Fix Committed'.

[su_v (suv-lp)]

<off-topic>
@Alvin - please accept my apologies for my impolite and impatient last comment - I'm aware that it does takes quite a while to export at such sizes, and success can only be confirmed at the end because Inkscape might fail at any point during that lengthy process.

on Windows XP, Inkscape rev 11367, at 300 dpi, I get a crash after about 10 minutes or so, with the messages

Crash reproduced on Windows XP, Inkscape trunk revision 11859.
Inkscape eats all available memory and then exits.
