Function Detail

processCcittModifiedGroup3FaxMsb

const proc: processCcittModifiedGroup3FaxMsb (in string: faxData, in pixel: whitePixel, in pixel: blackPixel, in integer: startLine, in integer: height, in integer: width, inout pixelImage: image)

Read modified CCITT group 3 faxData with MSB bit ordering into image. A modified CCITT Group 3 one-dimensional Huffman run-length encoding is used. The CCITT group 3 facsimile standard has been defined by CCITT in 1988. This encoding is used in TIFF files if compression = 2. MSB bit ordering processes the bits from the MSB (most significant bit) to the LSB (least significant bit). This function fills a part of the image destination. The part starts with startLine and extends over height lines.

Parameters:
faxData - Modified CCITT group 3 one-dimensional encoded fax data with MSB bit ordering.
whitePixel - Pixel to be used for white.
blackPixel - Pixel to be used for black.
startLine - First line of image to which the pixels are assigned.
height - Number of lines to be processed.
width - Width of the lines to be processed.
image - Destination of the pixel lines.
