Module tex

Lua bindings to interact with OpenGL textures.

This will allow you to load textures.

An example would be:

 t  = tex.open( "foo/bar.png" ) -- Loads the texture
 w,h, sw,sh = t:dim()
 sprites, sx,sy = t:sprites()
 

Functions

__gc (t)	Frees the texture.
open (path[, w=1[, h=1[, sx=1[, sy=1]]]])	Opens a texture.
readData (File)	Reads image data from a file.
toData (t)	Saves texture data as a png.
dim (t)	Gets the dimensions of the texture.
sprites (t)	Gets the number of sprites in the texture.
spriteFromDir (t, a)	Gets the sprite that corresponds to a direction.
setFilter (tex, min[, mag])	Sets the texture minification and magnification filters.
setWrap (tex, horiz[, vert[, depth]])	Sets the texture wrapping.

Functions

__gc (t)

Frees the texture.

Parameters:

• t Tex Texture to free.

open (path[, w=1[, h=1[, sx=1[, sy=1]]]])

Opens a texture.

Note open( path, (sx=1), (sy=1) ) Note open( file, (sx=1), (sy=1) ) Note open( data, w, h, (sx=1), (sy=1) )

Parameters:

• path string, File or Data Path, File, or Data to open.
• w number Width when Data or optional number of x sprites otherwise. (default 1)
• h number Height when Data or optional number of y sprites otherwise. (default 1)
• sx number Optional number of x sprites when path is Data. (default 1)
• sy number Optional number of y sprites when path is Data. (default 1)

Returns:

Tex The opened texture or nil on error.

Usage:

• t = tex.open( "no_sprites.png" )
  

• t = tex.open( "spritesheet.png", 6, 6 )
  

readData (File)

Reads image data from a file.

Parameters:

• File file |string File or filename of the file to read the data from.

Returns:

1. Data Data containing the image data.
2. number Width of the loaded data.
3. number Height of the loaded data.

toData (t)

Saves texture data as a png.

Parameters:

• t Tex Texture to convert to string.

Returns:

string Texture as a string.

dim (t)

Gets the dimensions of the texture.

Parameters:

• t Tex Texture to get dimensions of.

Returns:

1. number The width the total image.
2. number The height the total image.
3. number The width the sprites.
4. number The height the sprites.

Usage:

w,h, sw,sh = t:dim()

sprites (t)

Gets the number of sprites in the texture.

Parameters:

• t Tex Texture to get sprites of.

Returns:

1. number The total number of sprites.
2. number The number of X sprites.
3. number The number of Y sprites.

Usage:

sprites, sx,sy = t:sprites()

spriteFromDir (t, a)

Gets the sprite that corresponds to a direction.

Parameters:

• t Tex Texture to get sprite of.
• a number Direction to have sprite facing (in radians).

Returns:

1. number The x position of the sprite.
2. number The y position of the sprite.

Usage:

sx, sy = t:spriteFromDir( math.pi )

setFilter (tex, min[, mag])

Sets the texture minification and magnification filters.

Parameters:

• tex Tex Texture to set filter.
• min string Minification filter ("nearest" or "linear")
• mag string Magnification filter ("nearest" or "linear"). Defaults to min. (optional)

setWrap (tex, horiz[, vert[, depth]])

Sets the texture wrapping.

Parameters:

• tex Tex Texture to set filter.
• horiz string Horizontal wrapping ("clamp", "repeat", or "mirroredrepeat" )
• vert string Vertical wrapping ("clamp", "repeat", or "mirroredrepeat" ) (optional)
• depth string Depth wrapping ("clamp", "repeat", or "mirroredrepeat" ) (optional)
