Improve image scaling...

Postby Uncle Spooky » Tue Aug 05, 2008 4:17 am

I've been downloading full size artwork with the MWS Picture Assistant and adding to my MTG Studio Card Art collection.

Unfortunately, the downscaling in MTG renders the medium and small size images quite poorly, particularly the text is difficult to read. A quick test in photoshop shows that scaling from the full image to the smaller size results in very good images with very readable text... Of course, I'm not sure which scaling algorithm is being used in MTG Studio, but could you see if there's any way of improving the scaling to work well with the full images stored under Card Art?

Many thanks,

MTG Studio 2.0 uses bi-cubic(Photoshop like) smooth scaling of images. MTG Studio 1.x currently does not? This can be changed in the next versions I known how to do it, it is just on page 50 of my TODO list :wink:

Use bi-cubic SHARP - this is better for reductions.

MTG Studio 1.6.1 will support bicubic scaling.
I decided to completely rewrite the Card Preview component with the following changes:
1. Removed any Assembler code (used previously for performance when calling GDI rendering)
2. Use GDI+ library for drawing the fade in/out effect
3. Use interpolation mode High Quality Bicubic
4. Use High Quality Smoothing Mode
5. Add Flip icon for easily rotate the card image at 180 degrees for Flip Cards such as Budoka Pupil
6. Add Out of Print label for cards which officially will not be printed any more.

The sample below is from an 200x285 image resized as 480x680.

I hope you like it. :wink:
