I want to produce the effect of a text string fading out when it's too long to be displayed in a rect. This kind of effect is used in many apps.
My first solution was to simply draw the text and then on top of it draw a gradient fill ranging from the fully transparent color to the background color of the rect. This works fine, however only for solid opaque backgrounds. Now I have the problem that the background is not solid and/or not opaque. There is no longer such thing as "background color" I could use in the gradient. How do I solve this problem? I've tried to go the way of converting the text to a path and fill it with gradient, but encountered some problems: 1) I don't know the right line width to stroke the path, I only fill it, and so the path never looks of the same weight as the simply drawn text; 2) the path is not aligned to the baseline of text, and I don't know the right offsets, so the path is never aligned the same way as the simply drawn text. 3) gradient fill of this path did not produce smooth fade out for some reason. I'm hoping there is an easier way I've missed, but any advice is welcome! _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
