Picture frame image resolution

Rhino Rhino for Windows
1

Hi,
when creating a picture frame I often have the problem that the image appears in very low resolution. Is there a way to increase the resolution of the displayed image? I wanted to take measurements of scanned blueprints (the scans are very high quality in jpg format), but the resolution is really bad if loaded in Rhino.

Thanks in advance!

Hi Thorst- are the images very large? Can you post or send one of these to tech@mcneel.com (Att’n:Pascal) for a look?

thanks,

I’ve sent an email with a sample scan to you. Yes, it happens only with larger files, with considerably more than about 1 megapixel size.

Thanks,

Hi Thorst- I think beyond a certain size, Rhino resamples large images to display them - My understanding is that this is much more efficient if the image is sized to a power of 2, even if this involves adding a margin or cropping (slightly) . So, making your image 4096 by 4096 and then resizing to 2048 by 2048 yourself, or using the full size may look better- that said, your image looks good here as-is, so it may be a matter of graphics support as well.

Thanks for your answer. So does it look better on your machine than on this screenshot?:

The sampling is really so low that I can hardly see the smaller numbers.

Can I improve the graphic support with other options? Couldn’t find a relevant menu yet.

Here is a grab on my screen- zoomed in to see the dimensions-

Is that reasonable?

Wow yes this is just the full information of the original scan. Have you manipulated the image size therefore or was it just how I sent it to you? Can I change any options to get better graphics support of Rhino?

thanks,
