RAW format is a flexible file format for transferring documents between different applications and computer platforms. It is basically an import/export format rather than a storage format.
A RAW file has no predefined format, not even for image width and height, palettes, etc. RAW format consists of a stream of bytes describing the color information in the file.
You have two options when exporting to RAW format: binary (.raw) or text (.txt).
Image Specs | This section indicates the color mode, image size, and color depth. |
Binary options | Output: For 8-bit and 16-bit images, this menu is disabled and only indicates the color depth shown in the Image Specs section. For images with a color depth of FP-32 bits/channel, you can select the output depth. 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. Byte order: For 8-bit images, this option is disabled. Select whether the byte order is for PC or Mac. Alignment: Refers to the alignment of image data in file. Each row ends at a location, which is a multiple of 8 bits, 16 bits, 32 bits, or 64 bits. Header: Enter the number of bytes in the file before the first byte of image data. BGR (Reverse Colors): Select this checkbox to reverse the color order. |

Text options | Format: Select from Comma delimited, Tab delimited, Space delimited, Colon delimited, or Semicolon delimited. Output: For 8-bit and 16-bit images, this menu is disabled and only indicates the color depth shown in the Image Specs section.

You have three options when importing RAW files: binary (.raw), text (.txt), or comma separated values file (.csv).
Binary (.raw) is the most common selection since devices, like microscopes or various measuring equipment, produce binary (.raw) files.
Input Data | Canvas X Draw 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. |
