icetSetColorFormat,icetSetDepthFormat-- specifies the buffer formats
for IceT to use when creating images
void icetSetColorFormat( IceTEnum color_format );
void icetSetDepthFormat( IceTEnum depth_format );
When IceT creates image objects, it uses the formats specified by
icetSetColorFormatand icetSetDepthFormat.These will be the formats of
images passed to drawing callbacks (specified by icetDrawCallback or
icetGLDrawCallback) and of images returned from frame drawing functions
(icetDrawFrame or icetGLDrawFrame).
The following color_formats are valid for use in icetSetColorFormat.
Each entry is an RGBA color tuple. Each component is valued in
the range from 0 to 255 and is stored as an 8-bit integer. The
buffer will always be allocated on memory boundaries such that
each color value can be treated as a single 32-bit integer.
Each entry is an RGBA color tuple. Each component is in the
range from 0.0 to 1.0 and is stored as a 32-bit float.
No color values are stored in the image.
The following depth_formats are valid for use in icetSetDepthFormat.
Each entry is in the range from 0.0 (near plane) to 1.0 (far
plane) and is stored as a 32-bit float.
No depth values are stored in the image.
The color and depth formats are stored in the ICET_COLOR_FORMAT and
ICET_DEPTH_FORMAT state variables, respectively.
icetSetColorFormator icetSetDepthFormatwas called while IceT
was drawing a frame. This probably means that you called
icetSetColorFormat in a drawing callback. You cannot do that.
Call this function before starting the draw operation.
The color_format or depth_format given is invalid.
Calling either icetSetColorFormator icetSetDepthFormatdoes not change
the format of any existing images. It only changes any subsequently
The color format must be set before calling either icetDrawFrame or
icetGLDrawFrame. Doing otherwise would create inconsistencies in the
images created and composed together.
