Aliased fonts using the Text tool
Hello, I'm using the text tool to create diagrams for posting on the web. Most everything is working great, except that all the fonts I try to use end up aliased, which looks really terrible. Is there a setting I need to turn on, so that it looks good? Even at 18pt, it my diagram on screen looks like something off an old dot matrix printer. -- john

This is actually a flaw in OS X, not OmniGraffle. Pages (at least version 1.0) has the same issue as would any other app that has to display fonts in the same way. I forget the actual cause of the problem, but a google search should pull something up on it.

But it's been a long pain since I start using Omnigraffle, and this problem still exist on leopard. Hopefully Omni can do something workaround. I really really really want to this problem to be solved. here is the link if you want to experiment with the problematic .graffle file: [url]http://rapidshare.com/files/67774933/textRender.zip[/url]

So... I take it from the sheer lack of response that no one else uses OmniGraffle to create graphics for the Web? Because that's one of the main reasons I bought it: to add illustrations to my blog. The current text rendering support renders it nearly useless for that purpose, however, as the text in my illustrations looks like I scanned a photocopy of a badly printed book.
This would seem like something that people would really want to do. Note that I can export to PDF and then do a screenshot of the PDF in Preview and the text looks just fine. So why again can't OmniGraffle render text as well as Preview? |
Omni folks, any reply?

I'm not the Omni folks, but here is the explanation for why this happens:

Hello! Exported images are exactly what I'm having the problem with. I export the image to the clipboard so I can paste it into RapidWeaver, where I then publish it to the Web. John |
jwiegley,
I use Graffle with RapidWeaver all the time. I have no problem with fonts, even as small as 10, 11 points. I don't think you're technically "exporting" the image. What I do is export the image to a PNG format--the diagrams/tables remain very small in size and look great when used in RapidWeaver. Unfortunately I can't replicate what you do. I always get a "pasted graphic" text in my published site if I replicate the steps you describe. But if you truly export the image as PNG to your hard drive then drop it into RapidWeaver as an asset it works fine. |
Found it!
It turns out this problem was very easy to solve, there was simply one fact I didn't realize: OmniGraffle, being a vector drawing program, can rasterized at any DPI. Therein lay my problem.
When I copied the object to the pasteboard for dragging into Scrivener (and from thence to RapidWeaver), it was rasterizing at a default dpi of 72. Of course, 72dpi is even less than my screen's resolution, which is what caused the result to look like it had been xerox'd from a poor photocopy. Instead, I selected the graphic I wanted to export, choose File | Export from the main menu, and then picked a PNG file at 600dpi. This, of course, produced beautiful text within my exported graphic.

Apps in OS X place several versions of their images on the pasteboard and apps request the highest quality version they can utilize. Most apps in OS X are happy with the .PDF format, some apps aren't.
Try this, copy your text, open Preview, and do Command-N. That creates a new file from whatever's on the pasteboard. You should see that the file that gets created is a .PDF. So, the output from OG is a high res vector image for the apps that can accept it. I don't have Scrivener, but I'd imagine that it's not placing a high resolution PDF back on the pasteboard for RapidWeaver. |
