Image Import Resolution

[biagioni-paulette]

Is there a way to adjust Revit's default image resolution settings for imported images?

I'm inserting an image (company logo) and no matter what I do, it imports low-resolution and looks awful. I started with a vector file in Illustrator. All export out of Illustrator high quality and crisp, 300 dpi min. When I import into Revit (currently using 2021) they all import as 72 dpi, four times the size they need to be, and really fuzzy. I've read some other forum posts; they suggested trying a PDF, or turning off transparency in a PNG or TIF. So far I've exported as JPEG, PNG, TIF, PDF, with no luck on any of them. Any suggestions?

Revit seems to assume that the resolution of the image is 72 dpi.   We generate our images at 600 dpi.  After we import them, go to the properties of the image and multiply the width by 72/600.  That brings it to the correct size.

So when we bring in the image, the width shows as 1' 6 55/128".  Add an equal sign in front, and add * 72/600 at the end.

so: 1' 6 55/128"

becomes: =1' 6 55/128" * 72/600

The equal sign at the front tells Revit you're giving it a formula, and it will do the math.

I guess I should clarify - I don't want my images reduced to 72 DPI. I'd prefer them at 300.

Have you tried export the logo as DXF from Illustrator? That way your logo is always vectorized. If want to keep it rasterized, you can control with PDF import and change the DPI

Revit assumes the import dpi is 72 dpi when you bring it in.  Shrinking the image down doesn't reduce the resolution.  It will get you back down to the desired resolution.

Here's an example.  Two images.  One at 72 dpi, and one at 300 dpi and then reduced.  The 300 dpi image is a lot cleaner than the 72 dpi image.

I tried shrinking the original image down (72/300) to account for Revit's default adjustment, which made it worse. I tried enlarging the original (300/72 - inverse from your original suggestion) and that seemed to do the trick. Not sure if I actually figured out a workaround, or if I just sacrificed enough hours to the Autodesk gods that Revit finally felt pity on me. Either way - thanks for the input!
