Class Detail

cc.Texture2D()

This class allows to easily create OpenGL or Canvas 2D textures from images, text or raw data.
The created cc.Texture2D object will always have power-of-two dimensions.
Depending on how you create the cc.Texture2D object, the actual image area of the texture might be smaller than the texture dimensions
i.e. "contentSize" != (pixelsWide, pixelsHigh) and (maxS, maxT) != (1.0, 1.0).
Be aware that the content of the generated textures will be upside-down!

Field Detail

{Number} height
- Content height in points
{Number} maxS
- Texture max S
{Number} maxT
- Texture max T
{WebGLTexture} name
- <@readonly> WebGLTexture Object
{Number} pixelFormat
- <@readonly> Pixel format of the texture
{Number} pixelsHeight
- <@readonly> Height in pixels
{Number} pixelsWidth
- <@readonly> Width in pixels
{cc.GLProgram} shaderProgram
- The shader program used by drawAtPoint and drawInRect
{Number} width
- Content width in points
