I just downloaded the Photo Mosaic Python Plugin from the GIMPStuff web site.

I like the outcome, but the image bleeds/extends beyond the border edge. So I used the color select tool to select the border, did a selection invert and used the eraser tool to erase the bleed/over extension. Here are a couple of images.
And

Dang! I didn't know what to name it so I named it photo_mosaic and put it in my plug-ins folder. It doesn't show in Filters > Artistic. I did close and re-open GIMP after saving it, and I did allow it to execute as a program.

On the splash screen when it was being queried in the plug-ins it took a very long time to load. At first I thought GIMP was going to freeze there but then it went on and loaded.

I wish it saved as a file rather opening the plug-in. What do you have it saved as, Greg? Did you put a .py extension on it?

Ignore all the above. I put a py extension on it and it works fine.


The final image comes out larger than the canvas. You need to click Image > Fit Canvas to Layers and the image will expand to fit. Then do Ctrl + E to see the full-sized image.

I used the default settings and got this.



Before I started the script I made a copy of the original layer. Ran the script, then on the original layer I right-clicked the layer and scaled the layer to fit the current size. No "holes" in the edges.



If anyone wants the plug-in I saved, download the attached one below. I had to zip and save it for it to upload in here. Be sure to unzip it before putting it into your plug-ins folder.

Interesting ...

Very nice, Mike.

This is such a fun plugin.

Awesome work everyone! They even look good on the phone!

Oregonian, if you notice the image is cut away between each tile, but not along the outside edge. That's what I was mentioning. I, too, love this plugin! So much fun!

Here I took the original image (downloaded from the Gimpstuff site), divided it into 4 parts, ran the photo mosaic filter on each part, and put it back together. Viola!

I read through the posts here and thought I'd show what I mean when I talk about overlap.
This image is what I get.

I don't want the parts of the original image that are outside of the border.
This is the image I want. I must manually cut/erase the outer image data.

Here is a manual method using the plug-in with no border. Warning! Some settings of the mosaic filter causes a divide by zero error!

Ah! Now I understand, Greg. Yes, it would be nice if that overlapping didn't occur. It takes away from the effect of little snapshots.

Interesting effect to create torn pictures, neat script. =)


Settings

Try this, Greg.

Open an image and add an alpha channel. Image > Canvas Size. Unlink w & h. Add at least 50 pixels to both measurements. Click the Center button.

Do NOT do layer to image size. Run the photo mosaic plug-in.

I did this image of an elephant. I added 100px of canvas both ways and did not have any overlapping parts of the image. I filled in a bg layer with blue and cropped it, other than that the image is as it finished up from the plug-in.



This one I added 50px to h & w for canvas. I used the default settings in the filter, and the only change I made was to make the bg color red.

Wow, this filter is fun to play with. =)

I'm loving what you are coming up with, Rod. Good work!!!

I took a colorful image of a toy giraffe and used pinch and swirl, then i ran The stained glass filter,after that i took out all the inside black lines so i had individual stained glass panels gave it a white bg, then finally i ran mosaic filter.

As soon as I can get back on my computer, I will try it out! Sounds like it should work.

Oregonian! You rock! Your technique worked perfectly!!

I got a clue when I made this image with a transparent bg and it came out with no bg.


Thought I'd try adding some transparency around an image and see what came out. You can see the results. I think 50px or even less would work fine. Was a lucky

I hate to be the buzz kill, but I ran across the following bug. It is repeatable, at least on my machine. I will send this to the author.

I've had that message more than one time. I got another one when I changed a different setting also. It is a buggy plug-in. Time to get out the flyswatter.

I sent a msg to the author, with the URL for this page, so he can see the error msgs. I know a fair amount of script-fu, but haven't looked into python scripting, so I can't help to fix the problem... yet.
