4. Advanced HLS
– This allows the change of hue/saturation/lightness for the different
colour-bands in the image. You can for instance only saturate the red-orange colours
in an image. Or you can make those bluish parts of the image have a lower lightness
and become less obvious. The control is alike the gamma control and allows you to
add/delete control points at will. You can hover the mouse over the image and see
what hue's are under the cursor. This will make it easier to decide on which part of the
color-band you want to make changes. Next to this a histogram for the different hue's is
shown on top of the image. This histogram represent the image as it was created on the
processing-page and will not change.
5. Cropping
– You can crop part of the image by drawing a box around the feature you
want to work on. Both clipboard and saving will then only work for that area unless the
cropping checkbox (appears only when you draw a box) is unchecked. Be aware that
this crop will not follow the rotation so first rotate and only then use this. The program
will show the X,Y position of the top-left corner and the X,Y dimension of the crop you
are creating.
6. Overview Image
– Especially useful when working on large images, an overview
image shows where you are working.
7. Resize
– The same functionality as on the Wavelet-page.
8. Clipboard
– Allows direct copying of the image (or a cropped part) to the clipboard
9. Save
– Standard saving in several image formats including 16-bit FITS (3 separate files if
colour was used) and 48-bit TIFF.
