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');
imshow(out

have fun (and give credit)!
