Convert ascii text to a binary image using pre-computed templates.
Input strings can only contain standard characters (ascii character
32-126). First time char2img() is ever called with a given height h,
txt2img() is used to create a template for each ascii character. All
subsequent calls to to char2img() with the given height are very fast as
the pre-computed templates are used and no display/screen capture is
needed.
USAGE
masks = char2img( strings, h, [pad] )
INPUTS
strings - {1xn} text string or cell array of text strings to convert
h - font height in pixels
pad - [0] amount of extra padding between chars
OUTPUTS
masks - {1xn} binary image masks of height h for each string
EXAMPLE
mask=char2img('hello world',50); im(mask{1})
mask=char2img(num2str(pi),35); im(mask{1})
