I'm having trouble making an image semi-transparent. I have one image I'd like to set to 50% opacity and position it over another image(using composite operator:OverCompositeOp). Anyone know how an easy way to do such a thing?
A little background: I'm trying to make a good watermark to place over images, but I'm not fan of rmagick's built-in watermark() function or the shade-composite method.
