Text to Image conversion

when i try to run this code with text file contain binary values that i attach..,

% Text to image conversion
% % Open the txt file
fid = fopen('Big_Picture.txt', 'r');
% Scann the txt file 
img = fscanf(fid, '%x', [1 inf]); 
% Close the txt file
fclose(fid) 
% restore the image
outImg = reshape(img,[128 128]);
outImg = outImg';
figure, imshow(outImg,[])

it shows error :

Error using reshape
To RESHAPE the number of elements must not change.

Error in hexnew (line 10)
outImg = reshape(img,[128 128]);

pls mention What mistake that i had done ??

Why are you assuming that the file has exactly 128 * 128 hex numbers in it? Did you check length(img) ?

[Lalitha Sivaraman]

image size is 256x120

[Walter Roberson]

Could you show an example text line?

If the image is 256 x 120 and you were to read it in successfully, then you are not going to be able to reshape it as 128 * 128 . You would have more hope if the image had been 256 x 128 instead of 256 x 120: in such a case there might be a reason why two adjacent elements in the input should become one element in output.

Try

img = fscanf(fid, '%x', [256, 120]);

then

resizedImage = imresize(img, [128, 128]);
