Hello TwinDragon, nice to see all your questions
I was away a couple of days around the 10th of Feb and completely missed your posts.
I'll try to answer them all
Wish: double click to zoom at the location of the mouse.
I always program the scroll wheel button to double click.
Using the scroll wheel massively to zoom in, is much less ergonomical - it induces RSI like symptons.
Currently, if I click once, the fractal moves a bit to the bottom right. What's the purpose of that?
Hold the Control key and click with the mouse. The zoom size from Actions->Zoom size is used with the mouse in the center. I usually use zoom size=32 and use Control+mouse, rather than scrolling.
Wish: that there's a help file in the program.
So you can look up the mouse and keyboard possibilities are, for example.
There is a rather extensive description on
http://www.chillheimer.de/kallesfraktalerSometimes, the program recalculates without my intention to do so. Or I accidently clicked ctrl+n in stead of ctrl+m. Then the calculation work gets lost (and also the fractal location you were busy at).
I'd like very much an undo function: if, for whatever reason the program starts calculating again or changes to something else, that you can go one step back and that the calculations of that previous calculation were automatically saved.
Yes, would be nice...
Wish: save as BMP or PNG or any other lossless 24-bit color file.
(I don't think the program uses lossless JPG2000? I think that format is prettt much dead.)
Yes, would be nice... (I do have 32-bit code for saving as BMP/PNG but never inserted it here...)
Only old-fashing jpeg is used.
This looks like a bug. Did you save the location so that I can test?
'Actions / Set window size' gives problems; it can occur that the top of the program isn't accessible anymore. (Out of reach.)
Bug?
I've encountered this myself when I want to have large AA and set the size to something large (i.e. 3840x2160).
The window is centered, seems the size of the window cannot be larger than the screen, but the left point is set as if it could, far outside the screen.
Press Alt+Space and select Move in the popup, then move the windown into the screen again with the Arrows
How to set image size to 1024x768?
When x=1024, then y=576
Activate Actions->Arbitrary size. Then you can enter both width and height
Unfortunately it takes an hour to compile the program, because of all the formulas implemented with the floatexp variable that use "__inline" and are expanded...
