Ricoh Aficio SP W2470 Software Manual page 195

Bitmap images
For reference, the top position of the strip data must be contained in the value of
the StripeOffsets (273) tag. The data size (byte) after it is coded must also be spec-
ified by the value of StripeByteCounts (279) tag.
The byte at the end of the last page's strip data must be the same as the byte at
the end of the TIFF data.
The bitmap data must be one of the following types:
Bitmap image type
Monochrome: one sample, one bit (two colors)
per pixel.
Gray scale: one sample, four bit (16 colors) per
pixel.
Gray scale: one sample, eight bit (256 colors)
per pixel.
The bitmap image data must be coded using one of the following compression
methods.
Compression method
Uncompressed method
The value of the BitsPerSample (256) tag must
be set to 1. Each pixel must be white when the
sample value is 0, and black when the sample
value is 1.
The value of the BitsPerSample (256) tag must
be set to be at 4. Each pixel must be white
when the sample value is 0, and black when
the sample value is 15.
The value of the BitsPerSample (256) tag must
be set to be at 8. Each pixel must be white
when the sample value is 0, and black when
the sample value is 255.
Limitations
The image is not compressed.
Data for each pixel is stored in
the order it is created or
scanned. Extra data is added
to the end of each line as a pad
in place of unused bytes.
The value of the Compression
(259) tag must be set to 1 and
the T4Options (292) tag cannot
be included. Also, the value of
the StripByteCounts (279) tag
must be set as follows:
• 2 color monochrome image
ImageWidth ×
ImageLength / 8
• 16 color gray scale image
ImageWidth ×
ImageLength / 2
• 256 color gray scale image
ImageWidth × ImageLengt
