Description

Use PixelFormat to set the pixel format of the jpeg image to 8-bit for video drivers that cannot display 24-bit. The native format of a jpeg image is 24-bit. PixelFormat is used for decompression, that is, for reading in files. PixelFormat will also apply to a bitmap if the image is copied to it.
