Hi list(s),
I have some questions about how CoreImage can fit a color managed
workflow.
Core Image supports three color spaces:
One can be supplied at creation of the CIImage - I name it the input
color space
Two can be supplied at creation of the CIContext - the working and
output color space
My understanding (and please correct me if I'm wrong) is that before
applying any filter, Core Image will transform all images from the
input color space to the working color space.
Then all filters get applied and as a last step CI will convert the
final image from the working color space to the output color space.
But there's no mention on the rendering intent used for the color
space conversions done by CI. What is it? Why was it omitted?
For a Quartz Images (CGImage) I see the rendering intent can be
chosen by the user.
Also, CoreImage defaults to using the GenericRGB colorspace, unless
another is specified. Is it correct to say that using GenericRGB is
terribly wrong when drawing to a calibrated screen. Shouldn't one
always use the screen colorspace as output so CoreImage can try to
match the colors "as good as possible" to the screen.
Best
Mark
