ZoomFactor

is an option for DynamicImage that specifies the magnification factor of a zoom.

Details

  • The following settings can be given:
  • Automaticdetermined by image size (default)
    Fullshow entire image if aspect ratio permits
    zpositive magnification ratio

Examples

Basic Examples  (1)

By default, a zoom factor is used such that the larger dimension of the image fits the viewer:

Wolfram Language code: filename = ExampleData[{"TestImage", "Man"}, "FilePath"];
Wolfram Language code: DynamicImage[filename]

Specify the zoom factor:

Wolfram Language code: DynamicImage[filename, ZoomFactor -> .5]

Use ZoomFactor->1 to get the full resolution:

Wolfram Language code: DynamicImage[filename, ZoomFactor -> 1]

Magnify the image using zoom factors larger than 1:

Wolfram Language code: DynamicImage[filename, ZoomFactor -> 5]
