## gDPSetTileSize [macro]

Sets the tile descriptor parameters.

Syntax

    #include <ultra64.h> /* gbi.h */
    gDPSetTileSize(Gfx *gdl, u32 tile, u32 uls, u32 ult, u32 lrs, u32 lrt )
    gsDPSetTileSize(u32 tile, u32 uls, u32 ult, u32 lrs, u32 lrt )

Arguments

- gdl is the dsplay list pointer.
- tile is the tile descriptor index (3-bit precision, 0~7).
- uls is the texture tile's upper-left s coordinate (10.2, 0.0~1023.75).
- ult is the texture tile's upper-left t coordinate (10.2, 0.0~1023.75).
- lrs is the texture tile's lower-right s coordinate (10.2, 0.0~1023.75).
- lrt is the texture tile's lower-right t coordinate (10.2, 0.0~1023.75).

Explanation
Sets the parameters of a tile descriptor defining the origin and range of a texture tile.

uls, ult
  Defines the s,t texture coordinates at the tile origin. This is used when shifting a texture to straddle the face of a polygon. It also defines the lower-limit boundary when clamping.
lrs, lrt
  Used when clamping to define the upper-limit boundary.

For details, see Section 13.4, "Tile Attributes," and Section 13.5, "Tile Descriptor Loading," in the N64 Online Programming Manual.
