When adding an image, scaling options are available.
- None leaves the size as is. In terms of performance, None is fastest but changes the document.
- Shrink to desired size will reduce the size of the image if it does not fit in the desired width and height specified. Shrink to desired size always fits within the document. Nothing else moves, but it can be slow and too small.
- Fit to desired size will change the size of the image to match the desired width and height specified. Fit to desired size always fits the document, but it takes up space and can be slow.
