4. Use ImageScalingHorizontal and ImageScalingVertical to specify the horizontal and vertical

scaling ratio. For more information on how to specify the scaling ratio, see

Ratio.

Specifying the Scaling Ratio

Specify the scaling ratio in decimal point (maximum six decimal places) for ImageScalingHorizontal

and ImageScalingVertical. The setting range is 0.0625 to 1. If "1" is specified, the image will not be

scaled.

Caution:

Xscale automatically rounds down the width to the nearest value that is a multiple of 4

and rounds down the height to the nearest value that is a multiple of 2.

Note: When using Xscale, the horizontal and vertical scaling factors determine the size of the

virtual pixels in the scaled image. This information, plus any ROI that has been preset by the user,

determines the maximum number of whole virtual pixels possible in the output image.

Example 1

If you want to output an image with 50% scaling both horizontally and vertically, set

ImageScalingHorizontal and ImageScalingVertical to "0.5". (This is equivalent to the traditional 2 x 2

binning.)

Example 2

When you are replacing your camera with a new one but the new camera has a different pixel size and

resolution, you can reproduce the current camera's pixel size and output image size on the

replacement camera, using the

This example shows how to configure the ROI and ImageScalingMode settings when replacing the
