Overlay image requirements:
Image Formats
• Windows 24-bit BMP (full color)
• Windows 4-bit BMP (16 colors)
• OS/2 4-bit BMP (16 colors)
Overlay image limitations:
• The maximum overlay image size supported by the AXIS 210/211 is 640x480, even when using a lower resolution. The
overlay is automatically rescaled along with the image. See also the Technical Specifications, on page 46.
• Note that when a text overlay is also used, this reduces the amount of space available to the overlay image. To keep the
text readable at lower resolutions, the text overlay occupies proportionally more and more space, i.e., 16 pixels in height
at 640x480, 32 pixels at 320x240 and 64 pixels at 160x120.
• If the overlay is initially positioned so that part of it is outside the video image, it will be relocated so that it appears
over the video image, i.e. it is always the entire image that is displayed.

Image Size
The height and width of the overlay image in
pixels must be exactly divisible by 4.
