USINT32 MAKE_TEXTURE_FLAG ( int index, int map, int mode, int flags )

int index; // An integer value that is a texture index

int map; // An integer value that is a texture mapping mode

int mode; // An integer value that is a texture blending mode

int flags; // An integer value that is a texture bit-flag

Synopsis

#include "silver.h"

The MAKE_TEXTURE_FLAG macro combines a texture index, map, blend-mode, and flags into a 32-bit unsigned integer value.

Parameters

index is an integer value that is an index into the global texture table. It must be between 1 and 65535.

map is a texture mapping mode whose meaning is as follows:

Constant	Meaning
TEXTURE_MAP_SPHERE	The texture is applied to the geometry using a spherical projection
TEXTURE_MAP_CYLINDER	The texture is applied to the geometry using a cylindrical projection
TEXTURE_MAP_PLANE	The texture is applied to the geometry using a planar projection
TEXTURE_MAP_BOX	The texture is applied to the geometry using box-mapping

mode is a texture decal mode whose meaning is as follows:

Constant	Meaning
TEXTURE_MODE_REPLACE	The texture will replace the surface color when it is applied to geometry.
TEXTURE_MODE_MODULATE	The texture will be blended with the surface color when it is applied to the geometry.

flags is a bit-flag whose meaning is as follows. These flags may be combined with the Or operator '|'

Constant	Meaning
TEXTURE_FLAG_HORZFLIP	Flip the texture horizontally before applying it to geometry
TEXTURE_FLAG_VERTFLIP	Flip the texture vertically before applying it to geometry
TEXTURE_FLAG_STRETCHTOFIT	Stretch the texture to fit the geometry in a manner appropriate for the mapping.
TEXTURE_FLAG_IGNORE_ALPHA	If the texture image contains alpha data do not use it

Return Value

MAKE_TEXTURE_FLAG returns a 32-bit unsigned integer value that is appropriate for a Flags field of a TEXTURE_DATA data type.
