I'm trying to track down an issue where I see the color shift 240 degrees in Hue from inside the Core Image Filter chain. As a test to track down the problem, I'm using a Core Image Filter that I created that will display a solid color to the screen. The Core Image filter works in stand alone application and displays the correct color to the Open GL context. I'm using the passed in FxTexture from RenderOutput and wrapping that to a CIImage. The image is drawn to the Open GL context and the color in the original video frame is displayed correctly in color. There's no shift in the original FxTexture. However, when the core image filter is applied to this image, the solid color being displayed by the core image filter is shifted around 240 degrees in Hue. I've tried a bunch of standard core image filters for manipulating the color in the image and they all have the same problem. In the CIColor used for this custom core image filter, specifying a solid blue color results in a red color being displayed to the screen. Creating a solid green CIColor displays as solid blue. Creating a solid red CIColor displays as solid green. So while the FxTexture is displayed on the screen correctly, any manipulation of the image with Core Image filters or anything of that sort is shifted around 240 degrees in Hue. Again, all the core image filters that I've applied all exhibit this color shift. Any ideas what could cause this? This email sent to site_archiver@lists.apple.com
