Quick warning regarding loading images using the Loader class in Flash Player 9…

Image files that are saved with a CMYK profile will appear with inverted colours, this includes JPEGs. It might sound a random thing to encounter but it can happen if you are allowing users to upload images. So it’s probably best to re-save the images on the server using an RGB profile and also check for things like a high DPI, which is likely to also be the case with CMYK images that have been designed for print originally.

Should you want to do this in Flash after loading the CMYK image here’s an excellent resource to get you started:

Yeah all sorted. For anyone wishing to report bugs the URL is:

(I'm posting this because it is not the first URL you find when searching for it, which leads to bugs.adobe.com, allowing only Flex and BlazeDS bugs to be sent).

If I'm loading and CMYK image and just invert the colours for 'preview' so I can keep the image in the CMYK colourspace...will that work ?

The colours aren't inverted per-se, that's just how they can be described, really they are re-mapped to a different colorspace. So in reply I don't think that would work.

Is there a way to 'stream' the loading process? I can't help but think it would cut down on load times
