copied!<p>I'm not familiar with Apple's "Zoom to Fit" feature and its exact behavior (though I can imagine its most important property)...</p> <p>One potential disadvantage when relying on the different *Box values (<code>MediaBox</code>, <code>CropBox</code>, <code>TrimBox</code>, <code>BleedBox</code> and (the deprecated) <code>ArtBox</code>) is, that the <strong><em>real</em></strong> white space may still be different (mostly bigger) from their returned values.</p> <p>Ghostscript has a special device called <code>bbox</code> which returns the "bounding box" of all the pages' rendered content. Example:</p> <pre><code>gswin32c.exe ^ -o nul: ^ -sDEVICE=bbox ^ input.pdf </code></pre> <p>returns (for a random 3 page example I tried this command with):</p> <pre><code>%%BoundingBox: 86 122 509 719 %%HiResBoundingBox: 86.993997 122.993996 508.013984 718.001978 %%BoundingBox: 103 199 152 271 %%HiResBoundingBox: 103.408098 199.998064 151.107956 270.897953 %%BoundingBox: 103 195 185 271 %%HiResBoundingBox: 103.208059 195.000041 184.000002 270.897953 </code></pre> <p>You can probably ignore the high-precision <em>HiResBoundingBox</em> values. This leaves you with:</p> <pre><code>%%BoundingBox: 86 122 509 719 %%BoundingBox: 103 199 152 271 %%BoundingBox: 103 195 185 271 </code></pre> <p>These four values represent the coordinates of the lower left and upper right corners or a rectangle which surrounds all rendered pixels. The units are PostScript points (<code>72 points == 1 inch</code>).</p> <p>Compare this to the <code>*Box</code> values as returned by <code>pdfinfo.exe</code>:</p> <pre><code>pdfinfo ^ -f 1 ^ -l 3 ^ -box ^ input.pdf [....] Page 1 size: 421 x 595 pts (A5) Page 2 size: 421 x 595 pts (A5) Page 3 size: 92 x 80 pts Page 1 MediaBox: 0.00 0.00 595.00 842.00 Page 1 CropBox: 87.00 123.00 508.00 718.00 Page 1 BleedBox: 87.00 123.00 508.00 718.00 Page 1 TrimBox: 87.00 123.00 508.00 718.00 Page 1 ArtBox: 87.00 123.00 508.00 718.00 Page 2 MediaBox: 0.00 0.00 595.00 842.00 Page 2 CropBox: 87.00 123.00 508.00 718.00 Page 2 BleedBox: 87.00 123.00 508.00 718.00 Page 2 TrimBox: 87.00 123.00 508.00 718.00 Page 2 ArtBox: 87.00 123.00 508.00 718.00 Page 3 MediaBox: 0.00 0.00 595.00 842.00 Page 3 CropBox: 92.00 194.00 184.00 274.00 Page 3 BleedBox: 92.00 194.00 184.00 274.00 Page 3 TrimBox: 92.00 194.00 184.00 274.00 Page 3 ArtBox: 92.00 194.00 184.00 274.00 [...] </code></pre> <hr> <p><strong>Update:</strong> Here is a screenshot showing the thumbnails of the PDF document's 3 pages which I used to demonstrate the differences above:</p> <p><img src="https://i.stack.imgur.com/E7Vhz.png" alt="3-page PDF with different page sizes and *Boxes"></p>
