- I have a few questions about programming HAM mode graphics. Please answer if
- you know the answers. I have started working on programming HAM stuff, but
- there still are some things I don't know about HAM. BTW, this is ECS (HAM6)
- HAM I'm asking about (not AGA).
-
- 1. Is there are HAM (how-to/explanation/etc.) documents available on the net?
- 2. How do you get rid of the left edge ham fringing (if that's what it's
- called) that occurs when you scroll the ham image to the left (so that the
- left part of the image is offscreen). What I'm talking about is those long
- (varying length) lines (starting from left edge) of the wrong color that
- appear on certain scanlines. I know there is a way to get rid of it,
- because GIF_view 4.4 (on aminet) has a PERFECT option that gets rid of it.
- Anyone know how that option is implemented (or how to get rid of this fringing)?
- The author refers to it as "left border color distortion". I think I know why
- the color distortion occurs, and I figure writing a specific color to the
- first viewable pixel of each line would solve it, but I have no idea what
- color that should be. Am I right about how it's done? Any information you
- could give me on how it's done would be helpful... Thanks...

- Please email me (our news service isn't the best)...
