#
# An Icon is an image with two additional server-side resources: a shape
# bitmap, which is used to mask those pixels where the background should
# be preserved during the drawing, and a etch bitmap, which is used to
# draw the icon when it is disabled.
#
class FXIcon < FXImage
# Transparency color [FXColor]
attr_accessor :transparentColor
#
# Create an icon with an initial pixel buffer _pix_, a transparent color _clr_,
# and _opts_ as in FXImage. The transparent color is used to determine which
# pixel values are transparent, i.e. need to be masked out in the absence of
# a true alpha channel.
# If the flag +IMAGE_OPAQUE+ is passed, the shape and etch bitmaps are generated
# as if the image is fully opaque, even if it has an alpha channel or transparancy
# color. The flag +IMAGE_ALPHACOLOR+ is used to force a specific alpha color instead
# of the alpha channel obtained from the image file.
# Specifying +IMAGE_ALPHAGUESS+ causes FXIcon to obtain the alpha color from the background
# color of the image; it has the same effect as +IMAGE_ALPHACOLOR+ in the sense that
# the icon will be transparent for those colors matching the alpha color.
#
# ==== Parameters:
#
# +a+:: an application instance [FXApp]
# +pix+:: initial pixel buffer [String]
# +clr+:: transparency color [FXColor]
# +opts+:: options [Integer]
# +w+:: width [Integer]
# +h+:: height [Integer]
#
def initialize(app, pix=nil, clr=0, opts=0, w=1, h=1) # :yields: theIcon
