Method GLUE.BaseTexture()->set_image_data()
- Method set_image_data
void set_image_data(Image.Image|mapping(string:mixed) data, bool|void no_resize)
- Description
Set the contents (and size) of the texture from the supplied data. The data is identical to what would normally be sent as the last argument to glTex[Sub]Image2D() or an Image.Image object.
If no_resize is specified, it is assumed that the data will fit in the texture, otherwise the parts that extend beyond it will be discarded.
- Parameter data
Besides being an Image.Image object, data can be either of two types of mappins. First it can be a mapping with Image data.
"rgb" : Image.Image Texture image data.
"alpha" : Image.Image Optional alpha channel.
"luminance" : Image.Image Optional luminance channel.
Second it can be a mapping pointing out a shared memory segment.
"mem" : System.Memory The shared memory segment.
"mem_w" : int The width and height of the memory segment.
"mem_h" : int "mem_format" : int The format of the memory segment, e.g. GL.GL_RGB.
"mem_type" : int The low level format of the memory segment, e.g. GL.GL_UNSIGNED_BYTE.
