ImageByteFormat enum
The format in which image bytes should be returned when using Image.toByteData.
Constants
- png → const ImageByteFormat
-
PNG format.
A loss-less compression format for images. This format is well suited for images with hard edges, such as screenshots or sprites, and images with text. Transparency is supported. The PNG format supports images up to 2,147,483,647 pixels in either dimension, though in practice available memory provides a more immediate limitation on maximum image size.
PNG images normally use the
.png
file extension and theimage/png
MIME type.See also:
- en.wikipedia.org/wiki/Portable_Network_Graphics, the Wikipedia page on PNG.
- tools.ietf.org/rfc/rfc2083.txt, the PNG standard.
const ImageByteFormat(2)
- rawRgba → const ImageByteFormat
-
Raw RGBA format.
Unencoded bytes, in RGBA row-primary form, 8 bits per channel.
const ImageByteFormat(0)
- rawUnmodified → const ImageByteFormat
-
Raw unmodified format.
Unencoded bytes, in the image's existing format. For example, a grayscale image may use a single 8-bit channel for each pixel.

values
