Hello
I have noticed some rendering issues with Quartz Composer when initting a
QCRenderer with standard video colorspaces.
Specifically, I am using an ITU Rec. 709 colorspace and providing that as the
color space to a QC Renderer I create. Most patches and CI Kernels render ok
but I have issues in the console where images via the image loader, connected
to a simple billboard fail to render.
The error I receive is:
*** Failed creating texture on <QCOpenGLContext = 0x004DB450 | 2
rendering patches> from image <QCImage = 0x19205A00 | provider =
<QCProvider_CoreGraphics = 0x19222D80 | DOD = <QCRegion = 0x1922C370 |
rectangle = {{0, 0}, {627, 597}}> | colorspace = ICC Based RGB "sRGB
IEC61966-2.1" <0x188aeb60> | alpha = 1 | native pixel format = (null) | native
target = (null) | capabilities = 111 > | DOD = <QCRegion = 0x1922C370 |
rectangle = {{0, 0}, {627, 597}}> | transform = (null) | properties = {
}>
My gut tells me that the image, being marked as sRGB has a larger gamut than
Rec 709, and somehow that is causing a color conversion issue?
Is that correct? Should this just work?
