Filters

Image Marker includes some basic image manipulation.

• In Filter > Stretch, the user can set the brightness scaling, the two options being Linear (default) and Log.

• In Filter > Interval, the user can set the interval of brightness values which are displayed. The two options are Min-Max (default) and ZScale. Computation of the stretch and interval is done with astropy.

• In Filter > Gaussian Blur, the user can blur the image using a slider. The blurring computations are done using astropy and scipy.
