Scale Raster

Used to change the proportionate dimensions of an image. To scale an image, use an Active Scale or 3 Points Scale method. The Scale Raster tool adjusts the origin, pixel size, and dimensions of the image. The number of lines and pixels do not change.

You can access this tool from the following:

Ribbon: Drawing > Attach > Raster
Toolbox: Raster Control

Note: This tool is no longer blocked when more than one raster is selected.

Setting	Description
Method	Sets the method. Active Scale ? Scale by the active scale factors (X Scale and Y Scale). If a scale factor is 0-1 (for example, 0.25), size in that direction is decreased; if a scale factor is greater than 1, size in that direction is increased. 3 Points Scale ? Scale graphically, through the entry of three data points. The scale factors are computed by dividing the distance between the first and third points by the distance between the first and second points.
X Scale	Scale factor along view x-axis (horizontal), when Method is Active Scale.
Y Scale	Scale factor along view y-axis (vertical), when Method is Active Scale.
Proportional	If on, the raster (X-Y) proportions are maintained, when Method is 3 Points Scale.
