Image (gb.image)

This class implements an image.

The image contents are stored in the process memory, not in the display server like a Picture.

To get or set individual pixel values, you can treat the Image class as a two-dimensional array: Image[x,y] would refer to the pixel at position (x, y) within the image.

All methods except Copy modify the image and return itself.

This class is creatable.

This class acts like a read / write array.

Constants
Premultiplied   This constants represents an image whose pixels are encoded in premultiplied ARGB format.
Standard   This constants represent an image whose pixels are encoded in ARGB format.

Static properties
Debug   Return or set if debugging mode is enabled.

Properties
Data   Returns a pointer to the image data.
Depth   Returns the depth of the image.
Format   Return the internal image format as a string.
H   A synonymous for the Height property.
Height   Returns the height of the image.
Pixels   Return a copy the image pixels colors as an array of 32 bits integers.
W   A synonymous for the Width property.
