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.
Examples
Example
local texture = Texture.new("image.png", false, {transparentColor = 0xff00ff}) -- do not filter and make the color 0xff00ff transparent
local texture = Texture.new("image.png", true, {wrap = Texture.REPEAT}) -- enable filtering and repeat the texture
Available since: Gideros 2016.08
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.
Examples
Example
local texture = Texture.new(nil,300,400, false, {extend=false}) -- Create a 300x400 empty texture. Prevent gideros from extending the texture to the next power of two size
