Image manipulation

Tucked way behind the Annotations menu, the image manipulation panel allows you to adjust the visual settings of any file in V7 and its annotations.

From the image manipulation tab, you can adjust the fill and border opacity of your annotations, invert files, and adjust their brightness, contrast, image saturation, color map, and windowing.

None of the changes you make will change the properties of the source file, and all adjustments can quickly be reversed to their defaults:

Tips & Tricks

  • When labelling with polygons, adjust Annotation fill opacity to 100% to get a preview of how the annotations will appear when exported as a .png semantic mask.
  • To adjust window levels without opening the image manipulation tab, hold Tab and move your cursor up and down or side to side.
  • If your use case involves objects with difficult-to-identify contours, adjust the file's contrast, color map, or windowing to make them more easily distinguishable.
