How to

Scale an image

Background

Fixed Aspect Ratio (Proportional)

(e.g. Scaling x-direction will also scale y-direction proportionally to maintain the aspect ratio)

Unfixed Aspect Ratio (Disproportionate)

(e.g. Scale in x-direction without scaling in y-direction)

Steps to Accomplish

Option 1: Edit Handles
Select the image
Select an edit handle
By default, the image will scale with a fixed aspect ratio
Optional: Press [Alt] to unfix the aspect ratio
Click new position of edit handle to resize
Note: This method will work if the image's aspect ratio is set to fixed in the Geometry section of the Element Information dialog. This method does not change the "Aspect Ratio Fixed" property for the image.

Option 2: Element Information Dialog
Select the image
Open the Element Information dialog
Expand the Geometry section
Specify if you want the "Aspect Ratio Fixed"
Enter the scale factor for the axis you want to scale the image about

For Unfixed Aspect Ratio: Toggle the lock icon to appear unlocked
Specify the scale by entering a factor in the Scale input box
Enter a data point at the same location, whatever the scale
All views update to reflect your scale adjustments

Option 3b: Raster Manager – 3 Points Scale Method
Note: Images pasted into the model may not appear in the Raster Manager
Open Raster Manager (File > Raster Manager)
Select the raster to resize
Select the Scale icon
In the tool settings dialog, select 3 Points Scale
For Fixed Aspect Ratio: Check Proportional
For Unfixed Aspect Ratio: Uncheck Proportional
Enter a point to scale the raster about
Enter a reference point
Enter a point to define the amount of scaling
