[Kde-graphics-devel] Need test TIFF and JPEG images

Hi, me again! Does anyone have a good set of multipage TIFF images and/or JPEG 
images with lots of different EXIF metadata? I need some test images for 
MImage.

I'm on dialup so please don't attach anything without emailing me first to get 
confirmation, tho... I may already have gotten what I need and I don't want 
too many megabytes emails :P Certainly don't reply with any to the list, 
email me in private ;-)

If anyone knows of a site with good image test suites that would be excellent 
as well.

As for what I've been working on: bitmap support, shared image references, X11 
RGB database support, and of course still on the encoders. I got XPM, PNM, 
PNG, BMP, GIF (w/ animation), TIFF (multipage), XCF (with separate image 
layers), and JPEG decoders finished. Still need to do a few more and finish 
encoders for most formats except PNG. Of course Imagemagick is also supported 
so there won't be a lack of format support, but I want to do as many native 
ones as I can. 

I probably won't put too much more time on this before releasing because while 
the native encoders are good because they are more efficent than calling 
ImageMagick the only real important ones are the ones that use MImage's 
extended metadata handling: JPEG, TIFF, PNG, and XCF. The other ones can be 
done after an alpha release. Imlib2 hardly has any native encoders.

Another thing I've noticed is recently Digikam has been getting lots of GPL 
filters and I've seen a lot of places where I can optimize or utilize inline 
asm with good results. After the initial release I'll probably do an 
additional MImage GPL filter library for these effects. ImageMagick got some 
newer ones such as Radial Blur as well, and these would go into the GPL 
library because it's new wonky license. The GPL filter library can only be 
used by GPL applications. The normal filters are BSD.

Thanks.
