Playing with Julia in SketchBlock 2.6

Here is a sequence of images created with the "julia" filter coming with SketchBlock 2.6

SketchBlock generates fractals now? Looks nice.

It looks like the first few images would work as an animation (watching it grow).

Yes, just simple julia sets for this release, just had a conversation on IRC about some older fractal software, and after reseraching the basic julia sets don't take much code.

Animation: (if it works in this bbcode).

This is just so cool, Andy!

Feature request!

Lyapunovia sets pleeeeaaaaase!

Some code from the BeOS port from the Amiga 68k version is on the Lyapunovia site.

Hi Broadblues,
Thank you for the continued development of SketchBlock!

I seem to get an error with the Full Sobel convolve in SketchBlock 2.6
Perhaps it is a user error, but it locks sketchblock and requires a reset.

@ddni

Not sure why the error it works here, hopefully I haven't depended something on an unreleased python version.

Some info on the image your "sobeling" would help to debug that.

But to release SketchBlock after such a 'crash'

rx "ADDRESS SKETCHBLOCK UNSETAPPLICATIONBUSY"

This is analogous to the same issue in ImageFX when a rexx script lock the gui the exits early. A more modern app should deal with this, when possible, will have to investigate how.

(It's non trival as script run asynchronously and you can never easily know which script has done what )

Thanks Andy, rx "ADDRESS SKETCHBLOCK UNSETAPPLICATIONBUSY" helped.

I went back to v2.5 and confirm the same error happens with Full Sobel there too.

The image I am using it on is simple a rough scribble with the default brush.

I tested the sobelscript on the latest public and it worked fine for me, (it's damn slow though!) so not sure what is going wrong for you.

Your date may be different but does the size match?

I just reproduced the bug, I actually got a DSI before the error, which hit the stack , must be a memory trash in there somewhere in the ReadPixels function, need to investigate that.

In the mean time I wrote a new filter to do the combine operation, just about to test...

Okay, new version works for me, PM me an email address and I'll send you atest archive.

Thanks to BroadBlues, my issue with full sobel is resolved.
