Photo Mosaic Python Plugin

[PhotoMaster]

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.

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.

I like the outcome, but the image bleeds/extends beyond the border edge.

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.

[PhotoMaster]

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.

[PhotoMaster]

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!

[Oregonian]

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

[Oregonian]

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.

[Rod]

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

[Oregonian]

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.

[PhotoMaster]

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

[PhotoMaster]

Oregonian! You rock! Your technique worked perfectly!!

[Oregonian]

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.

[Oregonian]

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.

[PhotoMaster]

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.
