MapInfo Pro can read the following types of raster images:
- Monochrome images: Each pixel in a monochrome image can be displayed using two colors, usually black and white. These images take up the least amount of space and will display the fastest.
- 8-bit gray-scale images: Each pixel in a gray-scale image can be black, white, or a shade of gray. These pixel colors are stored in a palette of up to 256 different shades of gray.
- 8-bit color images: Each pixel in a color image can be any color from a palette of available colors. The set of available colors depends in part on the image file format and the source of the image. An 8-bit image contains eight bits, or one byte, of information from a palette of 256 different colors.
- 24-bit color images: Each pixel contains twenty-four bits, or three bytes, of information per pixel. The 3 bytes represent the red, green and blue color components, which means that the image can contain any of over 16 million different colors.
- 32-bit color images: Each pixel contains 32 bits, or four bytes, or information per pixel. These bytes represent the red, green, blue and alpha color components. This allows the image to have variable amounts of transparency or translucency per pixel.
For best results when viewing a raster image, we recommend using a high resolution video display.
