I create my icons as vector graphics without worrying *at all* about pixel boundaries and then scale them to fit at display time. Life improved markedly when I went this route. Although they might not be as sharp as 'pixel-perfect' bitmapped images it means I don't have to worry too much about the exact size at which they will be displayed. That said, my talents are limited and my icons are pretty boring. The alternative is to create 'pixel-perfect' bitmaps in a bitmap editor at the size they will be displayed, but it's hard work and I would only do it for a small image where display quality is paramount.
I would store your vector-graphics icons as PDF. You only need a .icns file for your application icon. Make your images with the correct aspect ratio and if you need the same image with two different aspect ratios, make two separate PDF's. Just my $0.02.

Short of getting a degree in graphic design or spending money on software or hiring a graphic artist, what can I do that will make better looking toolbar icons? The pdf art work looks good. The toolbar icons don't look so good, the edges are a little fuzzy. The toolbar icons at regular size are slightly larger than the original pdf. With an NSButton the pdf file works great and looks great when scaling set to none. When the pdf file is used as the image for the toolbar item, it gets asymmetrically stretched and looks horrible. Thus the reason for converting the pdf to an icns file. The "MakeThumbnail" application actually makes 9 images from very large to small. The large ones are obviously an overkill for the toolbar. The Apple Human Interface Guidelines has this to say "Although toolbar icons should conserve screen real estate (32 x 32 pixels is the recommended size), they should be inviting and easy to identify." This is nice to know but doesn't provide much help. --Richard _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
