#introduction
Yes, this is yet another image viewer.
No, it was not written to compete with or even to replace your
favourite image viewer (I'm frequently using Visage). It's simply
a little tool that I wanted to have, so I sat down and coded it.
#how to use it
h8jpg is a shell-only program. The argument template is:
FILES/M one or more filenames
(if omitted a reqtools file requester appears)
FITSCREEN/S scale images down so that they fit the screen
(they can be up to 50% wider and/or higher)
While displaying images h8jpg recognizes these inputs:
Space/LMB next image
Esc/RMB exit
#technical stuff
This is where we get to the drawbacks of the HAM8-RGBB technique:
-enormous chip memory consumption
(h8jpg first tries to display the images in their original sizes,
if there should be not enough chip memory available then they
will be scaled down)
-low screen resolution
(h8jpg uses screen mode $8820, that is "Super-High Res HAM" of the
system default monitor driver - PAL or NTSC. the images will look
like "Low Res" because each image pixel is made of 4 screen pixels)
