    copied!<p>I'm creating a dynamically generated PDF using FPDF.</p> <p>My PDF requires many exactly horizontal/vertical lines in a grid and when rendered they are anti-aliased and look very fuzzy and unacceptable to the client. I need to remove the anti-aliasing for these(or all) lines in the doc.</p> <p>I know this is possible because it's shown correctly in the adobe pdf specs itself <a href="http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf" rel="nofollow noreferrer">http://www.adobe.com/devnet/acrobat/pdfs/PDF32000_2008.pdf</a> (warning: big file) see the box in page 2 for how this should look.</p> <p>How would I duplicate the box shown on this page?</p> <p>-- EDIT -- </p> <pre><code>%PDF-1.6 3 0 obj &lt;&lt;/Type /Page /Parent 1 0 R /Resources 2 0 R /Contents 4 0 R&gt;&gt; endobj 4 0 obj &lt;&lt;/Length 44&gt;&gt; stream 2 J 1.00 w 20.00 821.89 m 200.00 821.89 l S endstream endobj 1 0 obj &lt;&lt;/Type /Pages /Kids [3 0 R ] /Count 1 /MediaBox [0 0 595.28 841.89] &gt;&gt; endobj 2 0 obj &lt;&lt; /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] /Font &lt;&lt; &gt;&gt; /XObject &lt;&lt; &gt;&gt; &gt;&gt; endobj 5 0 obj &lt;&lt; /Producer (FPDF 1.6) /CreationDate (D:20100311190240) &gt;&gt; endobj 6 0 obj &lt;&lt; /Type /Catalog /Pages 1 0 R /OpenAction [3 0 R /FitH null] /PageLayout /OneColumn &gt;&gt; endobj xref 0 7 0000000000 65535 f 0000000179 00000 n 0000000266 00000 n 0000000009 00000 n 0000000087 00000 n 0000000360 00000 n 0000000435 00000 n trailer &lt;&lt; /Size 7 /Root 6 0 R /Info 5 0 R &gt;&gt; startxref 538 %%EOF </code></pre> <p>This is a very simple PDF file that draws a single line showing the issue I'm having. I've figured out that the trick is to add this:</p> <pre><code>/Type /ExtGState /SA false </code></pre> <p>But I can't get it to work yet. SA is defined in 10.6.5 in the above PDF specs</p>
