Standard of jpg and png files.

[Andreas]

Hi,

I use Qt 4.6.2 with the library 'libqjpeg'.
With my program I can save png- and jpg- files.
And now my question:
Does anyone know where/how I can find out which standard (ISO /RFC) the png/jpg -files have?
I didn't find anything in the docu -maybe I am to stupid...

Thanks in advance

Andreas

Did you search in the docs for libjpeg and libpng? It took me two minutes to find it.

Anyway...
http://www.jpeg.org/jpeg/index.html
http://www.w3.org/TR/PNG/

It seems, that I am too stupid.
I searched in QtAssistant an in Online Docu Reference.
- I has to support JPEG ISO 10918: 94-98 and PNG RFC 2083
Ok, there are not so much standards for png and jpeg, but I can't find, whichone Qt supports.
I think the newest, but I need an evidence.

Could you give me a link to the corresponding Qt-docu please?

Qt supports whatever the libpng and libjpeg used by it support.
