first of all its almost same after downloading the file you upload on link,your file is in png format,if you want to increase the quality u can create a jpg file first and then using quality command u can see the change in it. a = imread('pdf.jpg'); imwrite(a,'pdf.jpg'); imshow('pdf.jpg'); imfinfo('pdf.jpg'); imwrite(a,'pdf1.jpg','quality',100); figure, imshow('pdf1.jpg'); imfinfo('pdf1.jpg');
hope this will help you...
