copied!<p>First of all: do not use <code>ImageResolution</code> when exporting! This buggy options is useless most of the time and does not do what one can expect. It works as an analog of <code>ImageSize</code>.</p> <p>Instead, use <code>Magnify</code> command and <code>Magnification</code> option of <code>Style</code>. They do what we want to get from <code>ImageResolution</code>!</p> <p>Now about the reason for the behavior showed in the first part of the question. Yes, it happens. And yes, it is machine-dependent. Is it a bug? Yes, at least a great imperfection. It it completely unexpected? As for me - not.</p> <p>It seems that the source of the problem is that rendering of graphics is in really made by the FrontEnd and the latter uses default settings for <code>Cell</code> when converting graphics to raster. </p> <pre><code>In[1]:= Options[Cell, PageWidth] Out[1]= {PageWidth -> WindowWidth} </code></pre> <p>Lets try to see how output of </p> <pre><code>Table[Rasterize[Style[x^2 + y^2, 40], Background -> None, ImageResolution -> r], {r, {300, 400, 500, 600}}] </code></pre> <p>looks at different <strong>run-time</strong> sizes of the notebook window:</p> <p><a href="https://i.stack.imgur.com/tZqJS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tZqJS.png" alt="enter image description here"></a></p> <p>One can see the obvious dependence of the output on the notebook window size.</p> <p>A workaround is to pass <code>PageWidth</code> directly to <code>Cell</code>:</p> <pre><code>Rasterize[ Cell[BoxData@ToBoxes@Style[x^2 + y^2, 40], PageWidth -> Infinity], ImageResolution -> 600] </code></pre> <p><img src="https://i.stack.imgur.com/Ejed4.png" alt="enter image description here"></p> <hr> <p>P.S. In addition. The only case I know when <code>ImageResolution</code> works as expected is PDF export with <code>"AllowRasterization"->True</code>:</p> <pre><code>First@ImportString[ ExportString[Plot3D[Sin[x + y^2], {x, -3, 3}, {y, -2, 2}], "PDF", "AllowRasterization" -> True, ImageResolution -> 200], "PDF"] </code></pre> <p>But it does not allow to specify transparent background.</p>
