Function Documentation

void* create_image_data (  png_bytep *  rows_ptr, int  c_type, TEXTURE *  tex )  [static]

Definition at line 137 of file texture.c.

TEXTURE* create_texture (  int  w, int  h )  [static]

Definition at line 245 of file texture.c.

void fix_png (  png_bytep *  rows_ptr, int  height, int  width )  [static]

Definition at line 300 of file texture.c.

void free_tex_tbl (  int  number, TEXTURE **  tex )

Free a texture table. This library uses a simple array table to manage several textures. This function erases a texture on that table. Be careful! A erased texture is retained on main memory. So, we have to free that memory area explicitly with using free_texture. Definition at line 127 of file texture.c.

void free_texture (  TEXTURE *  tex  )

Free a texture data. Parameters: pointer  to a texture data TEXTURE Unlock a memory area used for a texture image and free it. Definition at line 117 of file texture.c.

int get_exponent_number (  int  number  )  [static]

Definition at line 10 of file texture.c.

int load_textures (  int  tex_number, TEXTURE **  tex_tbl )

Set texture to VRAM. Parameters: tex_number  the number of texture to load tex_tbl  pointer for TEXTURE array VRAM is a working memory area for graphics. In case of PS2, VRAM means GS local memory. This function treats GS local memory device and load a image data to use texture to that memory. Definition at line 72 of file texture.c.

TEXTURE* read_png_file (  char *  file_name  )

read PNG file and create a texture file_name a PNG file This function reads a specified PNG image file and creates a texture data. Usually, a texture is a image data to painting 3D object's face. So, this function uses a PNG formated file and read it, then create a texture data. Definition at line 340 of file texture.c.

TEXTURE* read_png_file0 (  char *  file_name, int  flag )

read PNG file and create a texture file_name a PNG file This function reads a specified PNG image file and creates a texture data. Usually, a texture is a image data to painting 3D object's face. So, this function uses a PNG formated file and read it, then create a texture data. This function is equal to read_png_file function. But, turned up by kono-sensei. Definition at line 345 of file texture.c.

void set_default_texenv (  TEXTURE *  tex  )  [static]

Definition at line 39 of file texture.c.

void swap4 (  png_bytep  a, png_bytep  b )  [static]

Definition at line 282 of file texture.c.
