Render RGB text over RGB or Grayscale Image
by Davide Di Gloria
with the great contribution of Franz-Gerold Url
Render RGB text over RGB or grayscale images of ANY RESOLUTION!
usage:
out=rendertext(target, text, color, pos, mode1, mode2)
target ... MxNx3 or MxN matrix
text ... string (NO LINE FEED SUPPORT)
color ... vector in the form [r g b] 0-255
pos ... position (r,c)
optional arguments: (default is 'ovr','left')
mode1 ... 'ovr' to overwrite, 'bnd' to blend text over image
mode2 ... text aligment 'left', 'mid' or 'right'.
out ... has same size of target
example (generates the sceenshot above):
in=imread('football.jpg');
out=rendertext(in,'OVERWRITE mode',[0 255 0], [1, 1]);
out=rendertext(out,'BLEND mode',[255 0 255], [30, 1], 'bnd', 'left');
out=rendertext(out,'left',[0 0 255], [101, 150], 'ovr', 'left');
out=rendertext(out,'mid',[0 0 255], [130, 150], 'ovr', 'mid');
out=rendertext(out,'right',[0 0 255], [160, 150], 'ovr', 'right');

have fun (and give credit)!
