<p>From my perspective the behaviour of QImageReader is correct.</p>
<p>QImage::read docs:</p>
<blockquote style="border-left: 3px solid #a7b5bf; color: #464c5c; font-style: italic; margin: 4px 0 12px 0; padding: 4px 12px; background-color: #f8f9fc;"><p>Reads an image from the device into image, which must point to a QImage. Returns true on success; otherwise, returns false.</p></blockquote>
<p>QImage::isNull docs:</p>
<blockquote style="border-left: 3px solid #a7b5bf; color: #464c5c; font-style: italic; margin: 4px 0 12px 0; padding: 4px 12px; background-color: #f8f9fc;"><p>Returns true if it is a null image, otherwise returns false.<br />
A null image has all parameters set to zero and no allocated data.</p></blockquote>
<p>It seems totally possible that an empty image file is read correctly. In this case read returns true, but the resulting image is a null image.</p>
<p>For this patch I would however prefer a new error message, something like "the loaded document is empty".</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R223 Okular</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D8415" rel="noreferrer">https://phabricator.kde.org/D8415</a></div></div><br /><div><strong>To: </strong>trufanov, ngraham, Okular<br /><strong>Cc: </strong>aacid, progwolff<br /></div>
