QuartzCore.framework
Public Framework
Availabile 2.0 – present
Class Prefix CA

QuartzCore, also known as Core Animation, is an Objective-C framework that creates simple animations on UI elements.

Debugging

Signature unsigned CAGetDebugFlags();
Available in 2.0 –
Signature void CASetDebugFlags(unsigned flags);
Available in 2.0 –

Applications linked with QuartzCore will recognize the following debugging (boolean) environment variables:

Flag Environment variable
1 CA_COLOR_FLUSH[1]
2 CA_COLOR_COPY
4 CA_COLOR_OPAQUE[1][2]
8 CA_COLOR_NO_WAIT[1]
16 CA_AUTO_FLUSH
32 CA_PRINT_TREE[1]
64 CA_PRINT_OBJECTS
128 CA_LOG_IMPLICIT_TRANSACTIONS
256 CA_LOG_MEMORY_USAGE
512 CA_LOG_IMAGE_COPIES
1024 CA_PRINT_PERF
2048 CA_DISABLE_OCCLUSION_CULLING
4096 CA_DISABLE_DIRTY_REGIONS
8192 CA_LOG_TRIPLE_BUFFERING
16384 CA_COLOR_SUBPIXEL
32768 CA_DISABLE_RENDER
65536 CA_ALWAYS_RENDER
131072 CA_COLOR_OFFSCREEN
262144 CA_COLOR_DETACHED
524288 CA_COLOR_CACHED
1048576 CA_DISABLE_DETACHED

Alternatively, you can use the CASetDebugFlags() to update the flags in runtime.

Other environment variables

Additionally, the following environment variables not governed by CASetDebugFlags() also exist:

Environment variable Default Meaning
CA_BENCHMARK
LK_BENCHMARK
false -
CA_LOG_IMAGE_QUEUE_FRAMES false -
CA_PRINT_SHADERS false Log the vertex and fragment shader codes when creating them.
CA_DISABLED_EXTENSIONS NULL A space-delimited list of the following OpenGL extensions that should be disabled:
CA_DISABLE_WORKAROUNDS false -
CA_MAX_TEXTURE_UNITS ? -
CA_MAX_TEXTURE_SIZE ? -
CA_ENABLE_OGL true -
CA_ENABLE_TILING true -
CA_RESIZE_YUV_SCALE 0.8 -
MBX2D_OFFSCREEN
MBX2D_PAGE_FLIP
true -
CA_CLONE_OVERSCAN_AMOUNT 0.0? -
CA_CLONE_DISPLAY false -
