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


       #include <IceT.h>

       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.




       None known.


       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.
