Raw Image Import Options dialog box
Input Data Canvas normally detects the appropriate option. You can select either
radio button.
Image specs Mode: Select the color mode for the image: Grayscale, RGB, BGR, CMYK,
LAB, or Multichannel.
Source: Select the source image type: 8 Bits/Channel, 16 Bits/Channel,
16 Bits/Channel signed, or Float-32 Bits/Channel.
Target: Select the target image type: 8 Bits/Channel, 16 Bits/Channel,
or Float-32 Bits/Channel.
Height & Width: You must know these specifications to properly
import the raw image.
Channels: The number of color channels depends on the image’s color
mode.
Resolution: Set the resolution for the image. Use either pixels/in or
pixels/cm.
Quantity: Indicates the number of images stored in the file.
Gap: Indicates the number of bytes from the end of one image to the
beginning of the next.
Channels order: Select either Interleaved or Planar. These options are
disabled if grayscale is selected as the color mode. Interleaved refers to
an image having the pixels stored contiguously; i.e., rgbrgbrgb. Planar
means the color data is stored in separate 8-bit planes.
Binary options Byte order: Indicates whether the file originates from a PC or Mac.
Header: Enter the number of bytes in the file before the first byte of
image data.
Alignment: Refers to the alignment of image data in memory. Each row
ends at a memory location, which is a multiple of 8 bits, 16 bits, 32 bits,
or 64 bits.
Image types and filters
Canvas supports 8-bit, 16-bit, and floating point (32-bit) images. All image filters are available for 8-
bit images. For Binary filters, the 8-bit image must be grayscale (see "Binary filters" on page 749).
