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...

i have already mentioned the code above seems you havnt try it, try it first, it increases the quality to 100 % of the jpg image. you upload pnj image not pdf, and you can convert pdf to image format have a look to this link http://www.mathworks.com/matlabcentral/fileexchange/7952-text2image-convert-an-ascii-text-file-to-image hope you satisfied with the answer
