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:

jwiegley - I'm confused as to how OmniGraffle's display is a problem for web graphics unless you are doing a screen grab to obtain them? Exported and copy/pasted images should look fine.

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.

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.
