Ready to make a really pretty image? The quickest way to do this will be to have all your images ready and in the same directory.. so you can carry more than 1 URL easily.
Below..way way below..I'll have examples to show you just what you can do with this frame :-)
This moon frame requires you to take 2 trips to ImageMagick. Your first trip you will need this frame (or any of my other frames below) and the image you want framed. This image can be anything.. I used a scene and placed a transparent pegasus gif over that.. saved it and was ready to go from there :-)
Go to "composite" and use your image URL. Use "in" and "center" should work.. you may have to play with the +0+0 numbers to have it perfect. If there's not enough room for most of your image.. go ahead and re-size the frame.. but be sure to have 2 moon frames the exact same size (either before you start or make a copy when you get done with the next part)... you'll need a second one later :-)
Output and save as a gif. You'll see why in a minute :)
Go to the "paint" option and choose "matte" "replace" and erase the "white" leaving it blank. Click on the _red_ portion of the moon.
Now go to "composite" and use your background tile URL. Use "in" and check "tile across". Click composite.
Your tile will fill the one side and outline the bigger circle.
Use the URL of your moon framed image with "plus" "center" and be sure to uncheck the tile across.
