PNG File Export
 
I am creating images in Omnigraffle on the Mac to be used as iPhone and iPad icons and splash screens.

I set the Ruler Units to Pixels. I create a rectangle the size I want, i.e. 57x57 px or 320x480 px. I create the icon or splash screen

I choose Export, PNG format, and either select "Specific Region" and ensure the region is still the size [Height & Width] I want or select the rectangle and choose "Current Selection".

The output file is rejected by the Apple SDK as being incorrect size.

If I open the file in Preview, the inspector tells me the file is larger than I set at export. For example a 320x480 size is Exported by Omnigraffle as 764px × 1146px. A 57px x 57px is exported as 145 px x 145 px.

How can I get the specific size I request in PX exported from Omnigraffle?

It could be the DPI settings affecting it. Is it 72?

Sorry if this is answered in another thread I can't find. I'm also trying to create iPhone-type icons, e.g. 57x57 and 114x114 .png files. I discovered by trial and error that if I have a 1"x1" square in OmniGraffle and export it as a PNG with 54 dpi resolution (current selection, no margin), I can create a 57x57 pixel png. I'm sure there's something that I'm missing that would make this easier.

Unfortunately I can't generalize that to make a 114x114 pixel png... when I try exporting a 1"x1" square at 108dpi and do a 'get info' in finder, it shows as 115x114 pixels.

Is anybody else having luck creating iOS application icons in OmniGraffle?
