Despite the Bitmap API in Flash 8, I'd still recommend to use the GD library of PHP to do this, mainly for saving the resulting mosaic. Either way, you'll have to:
- 'homogenize' the size of the images in the pool. They will come in different orientations and sizes now, but in the end you have to map them to one of the square-shaped pixels in the target image. Cut out the central square part and size each to e.g. 100x100 pixels. - store the average color of each picture in a database. Get the average color by scaling a copy of the image down to 1x1 pixel, GD (or Flash) will do the work of calculating the average value. You may get better results by scaling down in several steps. - the average color is a value between 0 and > 16 millions - but the pool consists of only 3'000 images. To find a match for each pixel in the target image we'll not be able to work with identical colors, we'll have to find similar colors. Finding the closest 'websafe' color might be a good approach: http://chattyfig.figleaf.com/pipermail/flashcoders/2005-July/143567.html Now that the we have indexed all images and saved their average color in the db, we can take any other image, iterate through each pixel, get its color (probably convert to 'websafe'), search the db for images with matching colors, randomly select one of them, add it to the big, emerging mosaic. Be aware that these operations are very heavy on any processor (after indexing several ten-thousands 'googled' images, my ISP disabled the PHP script because it ate to many processor cycles...) If you do not need to do this 'on the fly' (and prepare for a rather slow flight...) I don't see a good reason why you would want to program this yourself - there are several programs, even free ones, out there (google). hth -------------- Andreas Weber motiondraw.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Corban Baxter Sent: Dienstag, 17.

I am looking to do the same thing but I am not sure where to start. I have this database with about 3,000 images I'd like to use to make photo mosaics out of. Does anyone remember the site for one and for two know of any tutorials that would get me started in creating this application. Thanks for the help everyone!
