Script GRADARA_text.m

% Create the text in an axis:
t = text(.05,.5,'GRADARA', ...
'FontSize',24, 'FontWeight','demi')

% Capture the text from the screen:
F = getframe(gca,[10 10 200 200])
Fsize=size(F)

% Close the figure:
% close

% Select any plane of the resulting RGB image:
c1 = F.cdata(:,:,1);
c2 = F.colormap
c1size=size(c1)
c2size=size(c2)
% Note: If you have Image Processing Toolbox installed,
% you can convert the RGB data from the frame to black or white:
% c = rgb2ind(F.cdata,2);

% Determine where the text was (black is 0):
[i,j] = find(c1 == 0);
Z0=c1(i(end),j(end))
sizei=size(i)
sizej=size(j)

% Read in or load the image that is to contain
%the text in the array X defined by MATLAB:
% load mandrill
[X,map4]=imread('Gradara.bmp');
sizeX=size(X)

% Use the size of the X image, plus the row/column locations
% of the text, to determine locations in the new image:
%seconda posizione whos
% whos
ind = sub2ind(size(X),i,j);
%terza posizione whos, i ind e j assumono valore 330

% % Index into new image, replacing pixels with white:
X(ind) = uint8(255);
valueXend=X(end)
