Unwanted outlines on 300dpi bitmap

[gwpriester]

This is nothing new but something I would like to see addressed.

When I create my stereograms for publication, I work at 300dpi, the industry standard resolution. My page size is 8" x 10" 960px X 768 My repeating panel size is 17% of the width: 163px x 768px 17 or 15% width work best for viewing. My repeating panel is positioned just off the page over the pasteboard at X -180 Y 0.

More often than not, when I create my stereogram, there is a faint outline in the repeating pattern. If my panel is black, the faint outline is more pronounced.

My work-around for this is to place a rectangle behind my repeating panel and make it the same color. (What we used to advise when working with 256 colors) and this works. For more complex panels I create a series of colored rectangles.

But all excuses aside, the bitmap creation should be more precise and not show a thin outline. Especially at 300dpi.

Acorn will say, make the panel 164px wide, Xara does better with even numbers. Egg will say to make the resolution 288px and that will solve the problem. And it does. But 300dpi is the resolution I work at. And it is the resolution my client requires. It is not negotiable.

I don't expect this ever to be fixed, just as from day one (in 1996 in my case) many of us who migrated from Corel Draw have asked for a Ctrl + R to repeat the last action.

It's just a slow day and I thought I would kavetch a bit.
