<div dir="ltr">If I may make a suggestion: use yellow and blue as highlighting colors instead of red and green because about 8% of males ( 0.5% of females) have some form of red-green color blindness (actually "color perception deficiency" would be more accurate). This means that all of us probably know a few people among our friends and colleagues who are red-green colorblind. Only about 0.008% have blue-yellow color blindness, so blue-yellow is a better choice than red-green.<div><br></div><div>Best Wishes --</div><div><br></div><div>--- Ed Trager</div><div> Bioinformatics,</div><div> Kellogg Eye Center</div><div> UMICH</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, May 25, 2016 at 3:07 PM, Sascha Brawer <span dir="ltr"><<a href="mailto:sascha@google.com" target="_blank">sascha@google.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi all,<br><div><br>we just released the <a href="https://github.com/googlei18n/fontdiff" target="_blank">fontdiff</a>, a small utility for testing fonts. When you modify a TrueType or OpenType font, fontdiff generates a PDF showing the typeset text both before and after the change. You can use this PDF to easily review the changes and spot any errors caused by a font switch. For every line in the text sample, the tool renders two raster images in high resolution. One image is typeset using the original font, and the second uses the new font. If there is any difference between these two high-resolution images (even if it’s just whitespace caused by kerning changes), the output PDF highlights the difference in color.</div><div><br></div><div><img src="cid:ii_154e946baaaf8ff4" alt="Inline image 1" width="466" height="114"><br></div><div><b><a href="https://github.com/googlei18n/fontdiff" target="_blank">https://github.com/googlei18n/fontdiff</a></b><br></div><div><b><a href="https://github.com/googlei18n/fontdiff" target="_blank"><br></a></b></div><div>— Sascha</div><div><br></div><div><br></div><div>Sascha Brawer · <a href="mailto:sascha@google.com" target="_blank">sascha@google.com</a> · <a href="mailto:sascha@brawer.ch" target="_blank">sascha@brawer.ch</a></div><div><br></div></div>
