NAME

       icetSetColorFormat,icetSetDepthFormat--  specifies the buffer formats for IceT to use when
       creating images

Synopsis

       #include <IceT.h>

       void icetSetColorFormat(   IceTEnum   color_format  );
       void icetSetDepthFormat(   IceTEnum   depth_format  );

Description

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.

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_NONE
No color values are stored in the image.

The following depth_formats are valid for use in icetSetDepthFormat.

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.

The color and depth formats are stored in the ICET_COLOR_FORMAT and ICET_DEPTH_FORMAT
state variables, respectively.

Errors

       ICET_INVALID_OPERATION
               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.

       ICET_INVALID_ENUM
               The color_format or depth_format given is invalid.

Warnings

       None.

Bugs

       None known.

Notes

       Calling  either  icetSetColorFormator  icetSetDepthFormatdoes not change the format of any
       existing images. It only changes any subsequently created images.

       The color format must be set  before  calling  either  icetDrawFrame  or  icetGLDrawFrame.
       Doing otherwise would create inconsistencies in the images created and composed together.
