Overview
SLGPUImage’s base source object
Images or frames of video are uploaded from source objects, which are subclasses of SLGPUImageOutput. These include:
- SLGPUImageVideoCamera (for live video from an iOS camera)
- SLGPUImageStillCamera.h (for taking photos with the camera)
- SLGPUImagePicture (for still images)
- SLGPUImageMovie (for movies)
Source objects upload still image frames to OpenGL ES as textures, then hand those textures off to the next objects in the processing chain.
