GNOME Bugzilla – Bug 555033
jpg memory allocation
Last modified: 2008-10-04 22:38:41 UTC
Please describe the problem: When opening a jpg image with the dimensions 15000px to 15000px and 8bit depth, gimp should allocate about 215MB. But it consumes round about 1.1GB Steps to reproduce: 1. open or create a jpg with the dimensions 15000px to 15000px with 8bit depth 2. save that jpg 3. reopen the jpg Actual results: Memory consumtion beyond expected calculation, Depending your RAM no working possible. Expected results: lower memory consuption. Does this happen every time? yes Other information: tracked this problem down to libjpeg62 on Linux or jpeg62.dll on windows. It's also reproduceable in the 2.4.x version of gimp.
If you think that this is a problem in libjpeg, why do you report it against GIMP?
I'm sorry if it is wrong to point to gimp. I thought as an image manipulation program that libjpg62 is a result of the work of the gimp-devs. Secondly, I believe it is libjpg62 but I could be wrong with that - mybe it's a wrong calculation in Gimp itself? Thirdly Gimp is the application where I found the problem and can reproduce it ... Anyway if you have a better place where to file the bug please tell me.
I think your bug report is based on a misunderstanding and wrong assumptions. If you want us to explain memory usage of GIMP to you, why don't you ask on the mailing-list? The bug-tracker is the wrong place for this.
I'm sorry if I caused any inconvenience. But please follow my steps. You will see and have to agree that the memory allocation of gimp is wrong, do you?
No, I disagree. And I kindly asked you to ask on the mailing-list if you need to have this explained. Perhaps it is sufficient though if you read the last section on http://www.gimp.org/unix/howtos/tile_cache.html
Ok. I'm pretty sure it has nothing, absolutely nothing, todo with the tile cache but I asked my question on the mailing list. Maybe you can help me what misunderstanding I'm in. I will leave this report at current resolved invalid state.
