Here you define the image type for the output files. The image type also decides the size of created raw data. These image types are available:
1 bit per pixel. 1 Bit pro Pixel. Gray values by rasterization. Color separation is available. Most black&white printers and typesetters use this format.
1 byte per pixel. 256 grayscales without rasterization or separation. Continuing grayscale images are used for further image processing most of the time.
3 bits per pixel. 8 colors by combining Red, Green and Blue. Rasterization may offer additional ditheRed colors. This format can be used when the data have to be proceeded in RGB but the Calamus rasterization should be used.
3 bytes per pixel. 16 million colors available by combining 256 nuances of Red, Green and Blue respectively, without rasterization. This format is used for color images, video applications, or if scanned images will have to be separated to CMYK later.
4 bits per pixel. 16 possible combinations from Cyan, Magenta, Yellow and Black. Rasterization may offer additional ditheRed colors. This way you can produce separated and rasterized color plane sets for placing in other applications or for archiving.
4 bytes per pixel. 4 billion colors available by combining 256 nuances of Cyan, Magenta, Yellow and Black respectively, without rasterization. Image type for ready separated, not rasterized color plane sets.
