Re: Large Image Sizes - CI & QC (Opus P. Penguin)

I work with large (4K, 8K, 16K per side) images, and was hoping I
could hit the ground running with all of the great filters in
CoreImage, not ot mention writing my own.  It seem that on my PB (ATI
Radeon 9000-class), QuartzComposer either 1) scales any input image
to 2K before any further processing (Image Importer) or 2) doesn't
render to a Billboard (Image With Movie).

I can confirm your findings. Core Image does the tiling automatically, but the Quartz Composer API (e.g. QCRenderer) fails to resize any CIImages that you pass to its input ports. I have heard that if you pass instead your input as an NSImage, the same problem does not occur.

I'm assuming the 2K is coming from the GL_MAX_TEXTURE_SIZE, but is
there any way to force it to use the full res?  Do I have to manually
break my images apart (tile), process them in separate pipelines,
then reassemble (composite) them in order to utilize CI?

As far as I could see, scaling images down to GL_MAX_TEXTURE_SIZE is the only workaround, but this problem has been filed on Radar, so hopefully we'll see it fixed soon.
