JPG image load and save are welcome additions in PureBasic 3.60, however, SaveImage() would be more useful if it were possible to set the JPG quality.
The current SaveImage() gives about 20:1 compression with corresponding low quality. For digital photographs you might use 3:1 for archiving and 8:1 for Web publishing. You need to set this depending on the application.

so basicly you're asking for a SetJPGQuality() command or the adding of an argument to the SaveImage() command? either way would be nice..

Well, more than nice, fixed 20:1 compression is no use at all for me.
Is this really missing?
Someone tell me if I've missed something here.

I would like to get a better control for the compression level when saving jpeg files, the given 10% steps (1%, 10%, 20%,... 90%, 100%) results are not so perfect for photos. A typically used compression value is 97% or so. Of course, enhanced features (like color sampling, Huffman optimizing etc.) would be fine, but that's another story...

We don't read [Implemented] topic anymore, so it's not exactly the same request, it's much better to open a new topic or it will probably be missed.

What? It didn't say that the other day when I read this topic.
