PURPOSE ^

Convert text string to a binary image.

SYNOPSIS ^

function masks = txt2img( strings, h, txtPrp )

DESCRIPTION ^

 Convert text string to a binary image.

 For each input string, creates a binary matrix of dimensions [hxw] that
 when displayed as an image shows the string. See example for usage.
 First, uses text() to display the text using Matlab's display
 functionality. Next uses getframe() to capture the screen and crops the
 resulting image appropriately.

 USAGE
  masks = txt2img( strings, h, [txtPrp] )

 INPUTS

  h        - font height in pixels
  txtPrp   - [] additional properites for call to "text"

 OUTPUTS
  masks    - {1xn} binary image masks of height h for each string
