I do not think the source is available.

Pretty cool smaller program for generating Guilloche patterns

When i downloaded this program and tried to run it it was missing a qt dll file.I have included this in the zip attached.

Just download and open the file and open guilloche execute and the program should open.

Here is a EMF converted to PNG

That's fun to play with. When you save the color seems a bit dark no matter which background you've used. A screen capture works well though.

Looks cool Rod; thought I already had this one but didn't. Thanks for your zipped version (found out that the installer was missing the right files too). GIMP is able to open WMF files by the way so wondered why you wanted to open it as an EMF file.

Why not an attempt; made black transparent.

Thanks! Another cool toy to play with

Looks like Spirograph on steroids.

It is fun.
Lyle i tried WMF files and couldn't open them either.

GIMP Error
Opening 'C:\Documents and Settings\Compaq_Owner.FAMILY-ROOM\Desktop\20120628-0730.wmf' failed:

Unknown file type

Strange Rod; I had no problem opening up WMF format GIMP. Even gave you the dialogue that a vector format will (i.e., you can choose to change the pixel size output if you like as you would get when opening a SVG file).

Lyle, you are using the Gimp-2.8 official release aren't you?
I am using Parthas build.
Are you dragging and dropping to Gimp or File>Open> select wmf?

WMF is pretty much a vector type file so it stands to reason it would open like a SVG file.
But when i open the open file dialog i see that Gimp doesn't even recognize the extension.
It isn't in the drop down list either. Do you have it in the drop down?

Funny thing is Gimp-1.2 does open them but doesn't support opaque.
I wonder if the plugin in Gimp-1.2 would work in Gimp-2.8?

In Gimp-2.6.8 the plugin crashes.


Upon 3 tries it did finally open.

GimpPortable 2.6.12 opens them.

I was able to track down the source c file for WMF.exe and i will try and compile it for Gimp-2.8.

Yes; drag and drop. I am also using the official build so maybe the wmf plugin somehow didn't get compiled in Partha's build.

Maybe a better solution Rod. Since the resulting wmf file is a vector, you can import it into Inkscape then save it as a SVG file. Just did that (not showing) and it worked like a champ. Always more then one way to skin a cat.

edit:

What the hey; went ahead and attaching the result svgz (compressed) file.

edit:

If you already downloaded the compressed file, go again and do so again. I added the cfg file to it.

Thanks Lyle. You and Sam were correct. I downloaded and installed the Gimp-2.8 official version and robbed the 2 wmf dll files and the binary.
This didn't work either. ... I don't understand why, unless the gimp dll is different?
The import window opens with a height and width auto set to 1 pixel, and the x and y are -2. Weird!

So i guess i will just use Gimp-2.6.12 Portable to open them until Partha adds the plugin.
Thanks for your help folks.

I thought I would try getting a wmf into Gimp (2.8, Vista 32). I had no problem with either File open or drag and drop. I got the usual Render Windows Metafile dialog. One thing I did notice; one of my renders from Guilloche was only 37x21. After opening in Gimp I was able to scale up with no noticeable degradation. This worked on a drag and drop, before saving.

Just out of curiosity.
Can be open or not?
As in 2.6 so - I copied all the *wmf to 2.8.
And it works (but only as in 2.6 for small files and read-only).
Wrote Lylejk-wmf - is good for Inkscape - wise words !
To try out (for experimenters) in Gimp 2.8.1 Partha win32bit files attached (of 2.6)

I will try your files MareroQ.
I did this once already and although it did open the render wmf dialog it won't open the file into Gimps image window.
