True Color BMP display on the ZX Spectrum Next.

What it is
==========

Viewer for 24/32 bit BMP with a somewhat crude UI. Everything is shown in a 256 x 192 window, hit QAOP / cursors to scroll if larger. A 2MB Next can show up to about 1280 x 1024 (I didn't test exactly though), 1MB - up to about 800 x 600.

Idea
====

R and G are shown on 256 x 192 x 8bpp L2 (each pixel is RRRRGGGG),  B is shown on (downsampled by averaging) 128 x 96 x 4bpp Radastan (each pixel is BBBB).  Then these two layers are mixed with addition.
Since Next palette is 3:3:3, the result can be pretty poor if a lot of shades of the same color are used (see example underwater pictures).
There's a gamma setting (hit space), governing how 0-15 pixel nibbles map onto the 8 possible intensities - linearly or logarithmically (log gives the darker tones more values).  May help some pictures.

Keys
====

0-9,A-H - .bmp files in the current dir (Space in the list - next page)
QAOP, cursors - move within large images
Space (when pic is shown) - toggle linear/log
EDIT,BREAK - go back to the file list

All pictures have been taken by me.

Have fun!
