zoomer(1) generate a video from a picture by zooming from one point to another


zoomer options...


zoomer automatically generates a video from a picture. It starts at the full picture and then zooms into the first point. Then zooms out and into the next point, etc. At the moment of reaching a point, zoomer will write a text (e.g. a name).

zoomer needs a picture (bigger is better) and a data file to define the points to be zoomed into.


the data file setting the details to be zoomed.
show a verbose output
how many frames between details
how many frames focused on the detail
the size of the text
the name of the output video
the name of the input picture (bigger is better)
will automaticaly delete a file with the same output name
will show a nice graphical progress bar
the video resolution in the WxH notation like 480x360


The data file is a simple text file to provide informaton about where zoomer must zoom. There must be one line by detail and no other information. The zoomer don't supports empty lines or commentaries.

The detail line has the pattern: X,Y Width Text

See a data example:

364,178 57 Bart 
233,246 62 Lisa 
396,274 52 Maggie 
302,059 61 Marge 
228,130 66 Homer 

The Width is the with of the soom square. The Height will be ever proporcional to the output setted height.
