Category: None Group: None >Status: Closed >Resolution: Duplicate Priority: 2 Private: No Submitted By: dooglus (dooglus) Assigned to: Nobody/Anonymous (nobody) Summary: GIF output looks rough sometimes Initial Comment: See http://dooglus.rincevent.net/synfig/gif-target.html for an example of how .gif output can look rough compared to .png output. I realise this is probably caused by the .gif format having a limit of 256 colours per frame, but even given that limitation it should be possible to make the results look better than this. ---------------------------------------------------------------------- >Comment By: dooglus (dooglus) Date: 2007-08-17 14:36 Message: Logged In: YES user_id=1546005 Originator: YES This is a duplicate of bug 1776135 (which I also raised), which goes into more detail than this one does. ---------------------------------------------------------------------- Comment By: dooglus (dooglus) Date: 2007-03-23 15:24 Message: Logged In: YES user_id=1546005 Originator: YES I looked into this to see what was happening, and it is due to the limited number of colours in the palette. synfig-core/src/synfig/palette.cpp's Palette::Palette(const Surface& surface, int max_colors) picks pixels at random from the image and adds them to the palette if they're different enough from the rest of the palette. This is likely to lead to small areas of colour the image not being represented in the palette. It's a non-trivial problem to pick the 'best' 256 colours for the palette, or even to define what 'best' means here. The dithering wasn't helping, either. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=757416&aid=1685573&group_id=144022 ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
