IJPEG


The IJPEG interface is designed to configure output files to be saved in JPEG format.

Properties

Enum ColorSpace

Defines the bit depth of the resulting image measured as the number of bits representing each pixel. It is both readable and writable.
ConstantValueDescription
CS_256GRAYSCALE136Grayscale image (256 hues, 8 bits per pixel)
CS_TRUECOLOR24True color image (24 bits per pixel)

Enum Mode
Defines the type of JPEG used to create output files. It is both readable and writable.
ConstantValueDescription
JPG_PROGRESSIVE1A progressive-scan file which creates the image as a series of interlaced images. This functionality shows lower-resolution representations of an image while it is still loading (useful for the Internet).
