Glad to hear from the you again. While I'm at it, I do remember those misshapen Mandelbrot sets... Do you plan on making more of these? And what are the formulas for the second video of misshapen Mandelbrot sets?

About the no such file or directory error, you have to return back to your kf-2.15.4 folder so that you can execute the bash command.

1. Seems some files are missing from the source archive. Try from git:
https://mathr.co.uk/kf/kf.html#source git checkout kf-2.15.4 tag

2. Maybe something broke with series skipping... No time to investigate, sorry.

3. Reuse center gave ugly videos with boxes visible. For zoom videos I recommend rendering exponential map with zoomasm to assemble final movie.

Bintray is no longer working now. It was shut down by JFrog, alongside JCenter,

I retried to compile KF

in the script prepare-msys.sh I replaced
Code: [Select]
https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.7z
by
Code: [Select]
https://osdn.net/projects/sfnet_boost/downloads/boost/1.74.0/boost_1_74_0.7z/
and it work.
Suspense for the next step.


edit :
error at   bash ./prepare-msys.sh 64

Code: [Select]

Hello.
I installed m4 to fix the previous error.

Yesterday I executed the shell "bash ./prepare-msys.sh 64"
and after 15-20 min, the script has displayed warning lines during all night like this.

Attached location takes 1m26 in 2.15.3, 6s in 2.14.10.2, 4s in 2.15.2.2.

When I disabled distance estimation and the slopes, render time was reduced to 28.597 seconds in 2.15.4.

Thanks for the bug report.

From the release notes in the manual https://mathr.co.uk/kf/manual.html#kf-2.15.3
Quote
...
- new: rescaled series approximation calculations for Mandelbrot power 2 (about 30% faster than the all-floatexp implementation, can be disabled if necessary in the perturbation and series approximation tuning dialog)
...
- known issue: some locations (especially Burning Ship “deep needle”) are much slower and need much more memory; workaround:
  -  disable “rescaled single” in number type selection dialog; and if still slow:
  -  disable “rescaled double” in number type selection dialog
...

Disabling rescaled double in the Number Types dialog (rescaled single is disabled by default) in 2.15.3 gets time down from 120 seconds to 15 seconds, but this is still 2x slower than 2.15.2.4 which takes 7.5 seconds on my machine.  The remaining difference can be eliminated by disabling Rescaled Series in the Perturbation Tuning dialog.  Rescaled series is supposed to be a speed enhancement but maybe the accuracy suffers and series skipping goes down, so overall time increases?

TL;DR try this as KFS settings:
Quote
NumberTypes: 38
UseRescaledSeries: 0

Drag'n dropping attached into a freshly opened KF gives a blank window in "done" state.  Click once and rendering starts.
But when opening it File-->Open it starts calculating right away as it should.
Seems specific to this krf (from another thread today).
Hardly a show-stopper but puzzling.

Also, when opening bob.krf KF window shrinks, menu only 1/2 visible, fonts also shrunk.
Manually resizing does not make menu visible again. Seems related to coloring.

On ctrl-W how can I set the size of bitmap and view in pixels the old fashioned way?
Say I want a 412X320 image for some reason?

Can't reproduce it here in Wine, does it still happen if you disable OpenGL in the KFR (with a text editor if necessary, or Ctrl-C Color dialog click OpenGL button bottom left unckeck the Enable checkbox)?

Say I want a 412X320 image for some reason?
See attached, you can select Custom (at the top of the dropdowns), and put in any values you want.

Here it does starts calculating the reference using 3 threads, but the screen is blank and it says "done" without any updates anywhere in the status bar.
Similar thing happens with the -l command line option (status bar is not updated properly).

I'll add both to the bugs list to maybe fix at some point.
