You set the size of an image during the import under the ‘Size’ tab:
(The image size can also be set on the image element, if you are using a dynamic image).
Here you can set either a resolution or a fixed size (Measure).
If you select Resolution, then the image size will depend on the resolution selected. The higher resolution you select the smaller the image will be. The reason is, that the image is a certain number of dots in height and width. The resolution is set as a number of dots per inch (DPI), so if you set a large DPI, then each dot will take up a very small space and the image will be small.
When selecting the measure you can set the size of the image via the Aspect ratio.
The aspect ratio can be set to these values:
(The measurement used is the measure, that you have chosen under ‘Setup’ and ‘Measure’).
