I still have problems getting this to correctly render in Windows Lyle. :lol

GUI fan here too i guess.

I did at first too Rod. The trick is to run the settings with the mask option. This gives you a white triangular image that can be used as a template to create your target for feeding to the full rendering script.

see the action entry; normally it is set to render:

Code: Select all

# Common Parameters
p=4
q=5
jpegQuality=100

# create visible mask
infile=..\\example\\ptest.jpg
outfile=..\example\\ptestmask.jpg
action=mask

# Fundamental Region Parameters
px=300.0
py=330.0
rx=50.0
ry=330
maskColor=black

# Render Parameters
renderedSize=360
borderSize=4
supersamplingRate=4
perturbationFactor=0
outOfBoundsColor=white
unreachableColor=white
nonSourceColor=red
maxIterations=20
negate=false

Please, someone tell me where I can get this stuff.

Did a Sourceforge check and found this site O.

I found freeimage in synaptic. Not sure about Fedora.

Poincare is at http://poincare.sourceforge.net/

Thanks Lyle and mahvin.

Sounds like you found the files you need....

Also sounds like a real GUI would make this way more usable. Maybe I'll put this on my list of things to do this summer. Given this is a GIMP group, I suppose a GIMP plug in would be preferable. A Windows GUI would be a hell of a lot easier, though (maybe).

Any programmers out there who would like to help????

Path of least resistence I say Bill; unless some GIMP guru can help you out that is with a GIMP GUI. I'm use to stand-a-lones; trust me. lol

I appreciate whatever cool result (even if it is a command prompt version) personally. GUI would be nice though.

I PM'ed Bob about adding the directory path to the environment file, per this comment I made earlier:

Quote:

2. For command line usage the syntax will be (I need to find Bob's instructions on how to avoid this step - but until then the command line entry is):

./poincare render.txt

Bob recommended I use the export option, as the example shows in the code below:

Quote:

Code: Select all

export PATH=$PATH:<add new path here>

replacing <add new path here> with the actual list of directories you want included.

IMPORTANT! - make sure you include the '$PATH' portion as that simply completes to all of the directories you already have in your path.

So if you leave out '$PATH' and just enter the one you want, all others will be gone (not the directories...just their inclusion in PATH).

After that all new entries you want need to be separated by a colon (without any spaces between colons and entries). For example:
Code:
export PATH=$PATH:/mahvin/blah:/mahvin/blah/blah
would add the directories /mahvin/blah and mahvin/blah/blah to the end of the existing path.

Hope this helps. If you still have problems, let me know.

By adding the PATH to the location where the poincare binary resides, you will no longer have to use ./ when calling the poincare binary in terminal.

Now that I have added the PATH, all I do is cd to the poincare directory and type:

poincare render.txt

Thanks to both Bill (for Poincare) and Bob for his help with the PATH variable.

Looks like you've been ninja'ed one too many times and taking matters into your own hands Mahvin. lol

Like your new Avatar.

paynekj started it. He wants a ninja emoticon (I agree we need one). Bunch of GIMP Chat ninjas that we are.

Just realized that I've not installed Poincaré since I acquired my new computer. Had a hard time finding this thread because of the special character "é". lol

Had to re-figure how to use this program and find my old mask references. Used wayback machine and a link to another site that no longer exists in order to find this thread. lol

Anyway, why not share some more fun here.

Does anyone know of a way to resize a selection to fit the dimensions of another selection. Would be cool to, say resize a seamless square to fit into the Poincaré target.

Didn't Saulgoode write a script that puts a layer into a selection?

I thought so too, but cannot remember the name. Did a, what I thought intelligent, search at the Registry but to no avail Rod.
