Sven Neumann Subject: Re: [Gimp-developer] Proposed usabillity enhancement for PNG That's not true. The current background color is used. So if you want the background to be white, then you should set your background color to white. No. maybe should but does not for me My background color is as default white and i seldom change that but all my png if converted to jpg get a black background and anyway if was that the reason the color will be not always black ,since there are millions of other possible BG colors But result never change : png transparency become in jpg is always black , never yellow green or red,and more relevant never white this at least on my gimp 2.6.1 with windows xp.

I looked up the PNG spec about this already when first trying to decide if it was a bug or a feature. To the letter spec says: The oFFs chunk gives the position on a printed page at which the image should be output when printed alone. It can also be used to define the image's location with respect to a larger screen or other application-specific coordinate system. I see it mainly as a a directive to the rendering engine to place the image at a offset. Its useful in contexts where PNG-s are used for rendering an UI etc. and supporting it is good. But in current implementation it is a hindrance to editing without any added benefits even to the user that WANTS to use it(see described use case in the first ). Now looking at spec, specially the last sentence, as I understand it these fields could be used to define an offset in a coordiante system totaly different of PNG-s own, with makes the way gimp handles it now totally incorrect for those usecases. The image can be unedtable because the system using it has a larger coordinate system and it ends up 100% outside canvas. --Alexia ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

As mentioned already on IRC, I'm sure we had exactly the same bug with another image file format, and IIRC the bug was resolved by simply ignoring the offsets. I've searched bugzilla but didn't find anything. It maybe was BMP (could could have been TIFF or something else). Does anyone remember that old bug? ciao, --mitch ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
