Can someone explaine to me why this happens, and how I can fix it. Actually I think I know why it happens.
I am making images for the web, my goal is to make the images transparent so they will work on any type of web background.
I draw the image with a white background, and the paint software generates a match to blend the ranges of colors on the background the to vectors. It looks fine on a white background, but as soon as I place the image on a different color background I get a distorted effect always around the vector portions.
I am saving the images in 89a format with white filtered out. To make is clearer I included a sample, compiled down into a bmp format.
The second image looks fine, but when placed on a different color background I get a distorted effect, which is by no mean acceptiable for a web graphic. I see a lot of very complex images on the web that work fine in any background type, what is the trick, that I am missing?
I know that the 89a format will filter out the color I select, but the blended shades of that color around the vectors, don't get blended, I don't think the format knows quite where the vectors start and stop.
