Hi,
I want to draw a shape filled with a basic pattern (horizontal
stripes,)
using a color specified by the user. Basically like an old-school
drawing
program would.
Viewing earlier list entries, I saw that to use a pattern fill, I
had to
create the pattern as an image, and use:
[ [NSColor +colorWithPatternImage: myImage] setFill];
Done and done---but this only paints the pattern exactly as I
created it,
using the colors in the image. How on Earth do I fill that pattern
in a
specified color?
Use a greyscale pattern and then reduce the alpha on the user's color
and fill again?
Or fill with the user's color and then fill with your pattern which
has an alpha channel.
Second approach might be easier to work with and present the user's
color.
