I have a screen with a logo on it, I would like the logo to scale with
screen size. I have tried more than a couple variations on:
# Construct an image
@logo = FXPNGImage.new(getApp(), File.open("logo.png", "rb").read,
IMAGE_KEEP)
# Prep an image Frame
image = FXImageFrame.new(self, @logo, LAYOUT_FILL_X | LAYOUT_FILL_Y)
image.backColor = FXColor::Blue
image.connect(SEL_CONFIGURE) do |sender, sel, evt|
if image.width > 100 && image.height > 100
@logo.scale(image.width, image.height)
end
end
This works, but the image “degrades” from all the scaling. How would I
go about keeping the original image? Any sort of “dup” on the FXImage
results in an exception (at least for me).
Thanks in advance

Ok I am still very interested if there is a better solution, but this
works for me:
# Construct an image
@logo = FXPNGImage.new(getApp(), File.open("logo.png", "rb").read,
IMAGE_KEEP)
stream = FXMemoryStream.open(FXStreamSave,nil)
@logo.savePixels(stream)
puts stream
@buffer = stream.takeBuffer
stream.close
p @buffer
# Prep an image Frame
image = FXImageFrame.new(self, @logo, LAYOUT_FILL_X | LAYOUT_FILL_Y)
image.backColor = FXColor::Blue
image.connect(SEL_CONFIGURE) do |sender, sel, evt|
if image.width > 100 && image.height > 100
stream = FXMemoryStream.open(FXStreamLoad, @buffer)
@logo.loadPixels(stream)
@logo.scale(image.width, image.height)
stream.close
end
end
end

At the risk of talking to myself too much. Here is the cleaned up
solution:
class FXScaledImageFrame < FXImageFrame
def initialize(parent, img, opts =
FRAME_SUNKEN|FRAME_THICK,x=0,y=0,w=0,h=0,pl=0,pr=0,pt=0,pb=0)
@img = img
FXMemoryStream.open(FXStreamSave, nil) do |stream|
@img.savePixels(stream)
@buffer = stream.takeBuffer
end
super
self.connect(SEL_CONFIGURE) do |sender, sel, evt|
if width > 1 and height > 1
FXMemoryStream.open(FXStreamLoad, @buffer) do |stream|
@img.loadPixels(stream)
end
@img.scale(width, height)
end
end
yield self if block_given?
end
end
