KCosine is Cosine implemented as kernel/filter
BSpline, Mitchell and Catmull-Rom use MitchellNetravali kernels with B/C = 1/0, 0.333/0.333 and 0/0.5 respectively
Lanczos2, Lanczos3, Lanczos4 use Lanczos kernels with a parameter 2, 3, and 4 respectively
2022-03-13 1.6.2
corrected: toolbar height problem on some computers
2022-03-13 1.6.1
new: EAA (Electronically Assisted Astronomy) helper - can stack images as they are captured or afterwards - online stacking process visualization only
dark subtration, flat division, debayering, asinh stretching, levels and hsl correction operations aplied on first image are replicated on each image of the stack
images are stacked by date/time order starting at the first image date/time and the origin folder is pooled for new images
hot/cold pixels can be detected on the stacking process
(all experimental)
new: dark image subtraction (with inversion detection for topdown/downtop fits)
new: flat image intensity division (with inversion option when using an inverted dark)
new: rgb alignment to image maximum point (ideal after debayering)
new: buffer/image max operation
new: display gamma slider - applies a gamma function to the displayed image
new: draw plot - superimposes on the displayed image the .png plot image file generated by plate solving
ui: if plate solved, Ctrl+* adds stars, Ctrl+Shift+* adds plot, Ctrl+Shift+Alt+* removes stars and plot
ui change: size/stroke drawing/painting sliders only visible when in draw/paint mode
2022-03-06 1.5.14
corrected/improved: restrict image alignment and merge levels stretching to RGB color space
corrected: image register failure crash when aligning unalignable images

improved: mouse draw size/stroke values
improved/corrected: internal bitmap alignment routines
new: rgb align to selection
registry: stretch and compression defaults
