Available since: Gideros 2011.6
Class: Texture

Description

Creates a new Texture object.

Texture.new(filename,filtering,options)

Parameters

filename: (string) The name of the texture file to be loaded.
filtering: (boolean, default = false) Whether or not the texture is filtered.
options: (table, optional) A table that specifies optional paramaters. The following options are supported:

  • transparentColor:Specify which color stands for transparent, for formats that don't supply an alpha channel such as JPEG
  • wrap:How to treat texels outside the texture. Possible values are Texture.CLAMP and Texture.REPEAT.
  • format:The GPU pixel format for the texture
  • extend:Wether the texture should be extended to a power of two size. Defaults to true.
  • scale:The scale at which this texture was made, if it cannot be determined by a suffix. Defaults to 1.

Example

-- do not filter and make the color 0xff00ff transparent
local texture = Texture.new("image.png", false, {transparentColor = 0xff00ff})
-- enable filtering and repeat the texture
local texture = Texture.new("image.png", true, {wrap = Texture.REPEAT})

Class: Texture

Description

Create a texture from pixel data.

Texture.new(pixels, width, height, filtering, options)

Parameters

pixels: (string) A string containing actual R,G,B,A compoents of each pixel in the new texture. Each component is stored as a byte. You can pass nil if you don't need to initialize texture content
width: (number) width of the texture to create
height: (number) Height of the texture to create
filtering: (boolean, default to false) indicate that the texture should be filtered optional
options: (table, optional) A table that specifies optional paramaters. The following options are supported:

  • transparentColor:Specify which color stands for transparent, for formats that don't supply an alpha channel such as JPEG
  • wrap:How to treat texels outside the texture. Possible values are Texture.CLAMP and Texture.REPEAT.
  • format:The GPU pixel format for the texture
  • extend:Wether the texture should be extended to a power of two size. Defaults to true.
  • scale:The scale at which this texture was made, if it cannot be determined by a suffix. Defaults to 1.

Example

-- Create a 300x400 empty texture. Prevent gideros from extending the texture to the next power of two size
local texture = Texture.new(nil,300,400, false, {extend=false})
