DxCreateTexture

This function creates a texture element that can be used in the dxDraw functions.

It is possible to use dxCreateTexture to load cubemaps and volume textures, but these will only be useable as inputs for a shader. The Microsoft utility DxTex can view and change cubemaps and volume textures. DxTex can also convert standard textures into DXT1/3/5 compressed .dds which should reduce file sizes.

Syntax

element dxCreateTexture ( string filepath [, string textureFormat = "argb", bool mipmaps = true, string textureEdge ] )
element dxCreateTexture ( string pixels [, string textureFormat = "argb", bool mipmaps = true, string textureEdge ] )
element dxCreateTexture ( int width, int height [, string textureFormat, string textureEdge, string textureType, int depth = 1 ] )

Required Arguments

• filepath: The filepath of the image. (.bmp, .dds, .jpg, .png, and .tga images are supported). Image files should ideally have dimensions that are a power of two, to prevent possible blurring.

or

• pixels: Pixels containing image data. ('plain', 'jpeg' or 'png' pixels can be used here)

or

• width: Desired width (Must be a power of two. e.g. 128, 256)
• height : Desired height (Must be a power of two. e.g. 128, 256)

Optional Arguments

• textureFormat : A string representing the desired texture format, which can be one of:
  • "argb" : ARGB uncompressed 32 bit color (default)
  • "dxt1" : DXT1 compressed - Can take a fraction of a second longer to load (unless the file is already a DXT1 .dds). Uses 8 times less video memory than ARGB and can speed up drawing. Quality not as good as ARGB and does not support alpha blending.
  • "dxt3" : DXT3 compressed - Can take a fraction of a second longer to load (unless the file is already a DXT3 .dds). Uses 4 times less video memory than ARGB and can speed up drawing. Quality slightly better than DXT1 and supports smooth alpha blending.
  • "dxt5" : DXT5 compressed - Can take a fraction of a second longer to load (unless the file is already a DXT5 .dds). Uses 4 times less video memory than ARGB and can speed up drawing. Quality slightly better than DXT1 and supports crisp alpha blending.
• mipmaps : True to create a mip-map chain so the texture looks good when drawn at various sizes.

ADDED/UPDATED IN VERSION 1.3 r4035:

• textureEdge : A string representing the desired texture edge handling, which can be one of:
  • "wrap" : Wrap the texture at the edges (default)
  • "clamp" : Clamp the texture at the edges. This may help avoid edge artifacts.
• textureType : A string representing the desired texture type, which can be one of:
  • "2d" : Standard texture (default)
  • "3d" : Volume texture
  • "cube" : Cube map
• depth: Desired number of slices when creating a volume texture

Returns

Returns a texture if successful, false if invalid arguments were passed to the function.

Example

addEventHandler( "onClientRender", root,
    function()
        if myImage then
            dxDrawImage( 100, 350, 300, 350, myImage  )
        end
    end
)

-- Use 'toggle' command to switch image on and off
addCommandHandler( "toggle",
    function()
        if not myImage then
            myImage = dxCreateTexture( "moonpig.png" )  -- Create texture
        else        
            destroyElement( myImage )                 -- Destroy texture
            myImage = nil
        end
    end
)
