NAME

icetImageGetColorFormat,icetImageGetDepthFormat-- get the format of image buffers

Synopsis

#include <IceT.h>

Description

icetImageGetColorFormatand icetImageGetDepthFormatreturn an entry in an enumeration that specifies the data format stored in the given image. This format determines which one of the icetImageGetColor or icetImageGetDepth functions to use and the form of the resulting data.

Return Value

icetImageGetColorFormatreturns one of the following values with the associated meaning for the format of the stored color data.
ICET_IMAGE_COLOR_RGBA_UBYTE

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.

ICET_IMAGE_COLOR_RGBA_FLOAT

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.

ICET_IMAGE_COLOR_RGB_FLOAT

Each entry is an RGB color triple. Each component is in the range from 0.0 to 1.0 and is stored as a 32-bit float. Note that there is no alpha channel, so the color blending composite mode will not work with this color format.

ICET_IMAGE_COLOR_NONE

No color values are stored in the image.

icetImageGetDepthFormatreturns one of the following values with the associated meaning for the format of the stored depth data.
ICET_IMAGE_DEPTH_FLOAT

Each entry is in the range from 0.0 (near plane) to 1.0 (far plane) and is stored as a 32-bit float.

ICET_IMAGE_DEPTH_NONE

No depth values are stored in the image.

Errors

None.

Warnings

None.

Bugs

None known.
