IndexedColor images select pixel colors indirectly through a palette of up to 256 colors. Use Image#palette to access the associated Palette object.
Like Image#merge_from except an optional final argument can be specified to preserve the hue of the source by converting the destination pixels to grey scale before the merge.
# File lib/gd2/image.rb, line 753 def merge_from(other, dst_x, dst_y, src_x, src_y, w, h, pct, gray = false) return super(other, dst_x, dst_y, src_x, src_y, w, h, pct) unless gray SYM[:gdImageCopyMergeGray].call(image_ptr, other.image_ptr, dst_x, dst_y, src_x, src_y, w, h, pct.to_percent.round) self end
