Any chance if it is somehow possible to retrieve a list of the actual images used to build the mosaic? I'd like to be able to somehow move my mouse over the mosaic image and be able to click each and every image in the mosaic and then visit for instance a page with some background info on that very image.

I already looked around in the sourcecode for a sec but didn't find a solution right away.

i have the following directory structure:
/dir
-- test.jpg
-- collection/
-- small_img1.png
-- small_img2.png
-- and so on...

i invoke pymos using: me@mylaptop: ~/dir$ pymos test.jpg output.png ./collection/

this is what i see :

IndexError: list index out of range

my test.jpg is 256x256 and all collection images are 75x75

Ran into a small issue with the build_mosaic() function in core.py, line 76:

files = glob.glob(os.path.join(collection_path, '*.jpg'))

My files ended with the extention "*.JPG". The traceback or the error I got was the following:

Traceback (most recent call last):

    if (colormap[match[2]][2] == None):   # has not been resized yet
IndexError: list index out of range

which was rather unhelpful.

Two points:

1. A case insensitive glob might be better here.
2. One should make sure that the number of files is not 0 in the collection_path directory.

For some reasons it didnt work when I had the attached image in collections folder.

• also got to fix the b/w image issue
• the absolute path issue

how long does the program take? does the program take a longer time if the input images have large size or? What other factors affect the program's speed or the quality of the final mosaic?

** todo in some free time sometime later.

while input and output images work fine even on bigger sizes,
it was an assumption that users would supply a folder with real small thumbnails as collection param.
If some one passes a directory full of real digicam pics as collection, in most cases it freezes the user's system.

Solution - precalculations based on source dimensions and zoom factor

• warnings when more than a tolerable number of big images are found in thumbnails.

from @meshaabi

nah i have 2.5 gigs ram free.. source is 500 images.. worked with -z 2

btw was checking out the src.. you are checking every pixel on the image.. the index builder died when i tried to use the 7.1 megpix pics from my camera..

maybe could check pixel blocks or first generate a thumbnail itself before getting to average pixel counting
