This was mostly an excuse to play a bit with the
Python Image Library (PIL).
Contrary to most other on-line or standalone bubblers, BubbleRand is used as a script and take an image, a mask,
and then start creating random bubbles to avoid showing the masked zones.
It can also create gradients, and generate a number of frames.
Now for some samples - thanks to my friend Manu for allowing me
to use some photos of her.
Here's an image generated using just a simple mask. Red pixels marks the zones that should not show:
It's also possible to use the blue color to ensure that some zones will show:
Here's an Animated GIF created assembling 6 different frames:
A look to all the different options and some notes:
usage: bubblerand.py [-h] [-v] [-f num] [-m mask] [-s factor] [-o output]
[-c1 color1] [-c2 color2] [-vg] [-b] [-d]
Create bubbled images from an image & mask pair
image original image file
-h, --help show this help message and exit
-v, --version show program's version number and exit
-f num frames to create (default: 1)
-m mask mask to use (default: None)
-s factor rescale bitmaps before processing (default: 1)
-o output output filename (default: bub.bmp)
-c1 color1 starting gradient color (default: black)
-c2 color2 ending gradient color (default: blue)
-vg vertical gradient (default: False)
-b bigger bubbles (default: False)
-d display output (default: False)
The only needed parameter is the source image file (in any usual format). If the mask name is omitted, it's assumed
to be a PNG file, with the image name + "_mask". If the "-f" switch is used to create many frame, a 5 digit counter
is added just before the file extension.
The "-s" switch is used to get better quality results when dealing with low res images.
Or can be less than 1 to speedup the calculations. The option to use bigger bubbles is useful when the images
have large areas that should remain hiddens, as small bubbles will tend to show the outline of the mask.
It's possible to specify an output filename; the format will be determined automatically by the file extension.
When creating gradients, it's possible to use any color string recognized by PIL, like "yellow", or "#ffff00", etc.
To quickly show the results (if only one image is created), use the "-d" switch.
