Post-Processing

Note: These options munch processing power compared with the options in previous sections. They work by producing an intermediate image of the screenshot, and then performing actions upon it. Once any of these options are enabled, the shot will take longer to complete, due to the extra processing involved.

Normalize image

This checkbox transforms the image to span the full range of colour values. Default is off.

Equalize image

This checkbox enables histogram-based image equalization. Default is off.

Enhance image

This checkbox tell Screen-Shooter to clean up the image as best it can, and try to remove any noise. Default is off.

Despeckle image

This checkbox reduces spotting by removing single pixels which are very different in colour from their surroundings. The default is off.

Sharpen image by factor

Sharpening the image sharpens the image. The default is a factor of zero, but it can be raised to 100%.

Rotate image clockwise

This is how many degrees clockwise to rotate the image. The default is 0: unrotated.

Adjust gamma

This checkbox enables you to adjust the gamma. The gamma value is a value to do with the intensity of the lightness of an image (and rather complicated). The range Screen-Shooter provides is from 0.8 to 2.3 with a default of 1.6. This is not a linear (straight) scale so you will need to experiment. Lowering the gamma produces a darker image. Raising it produces a lighter one.
