This DPI setting function was removed in Rhino 8. There is no way to define the DPI amount. Tried different ways without success. Tried to increase the quality by setting “Final Quality”, tried to increase the scale in Capture Viewport to File panel…but nothing changes.
Hi @Paulo_Pugliesi_Filho
Since dpi only makes sense for physical units (and not for pixels), you’ll have to change the units to either inches, mm or cm.
The “DPI” setting doesn’t actually mean anything. The resolution is the resolution. All it’s going to affect is how it’s scaled initially when you drop it into Word. Its existence has never made a whit of difference to my workflow since 1997.
The dpi setting merely calculates the size in pixels from the physical size and the requested DPI (dots pr. inch), so if it’s 2"x3" at 300 dpi, it’s 600x900 pixels, but the file written is still “tagged” as being 72dpi. I remember this being mentioned before many, many years back, and obviously it still hasn’t been changed. I think @nathanletwory wrote a little plugin for it, but it might only be for renderings, not view captures.

But why there is a DPI setting if the output image is not according to the setting?
And the DPI makes difference when you need to display the image in bigger screens. For example, if you have an image with 72 DPI, it may be good for ordinary monitors. But if you need to display this same image in a big screen like a projection in White Board, you can “see” the lost of resolution. In this case, 300 DPI is way better.
The DPI in the image file is just a scale to use for printing, as a default. It means nothing in any other context. The pixel resolution is all that matters.
Other people who have complained about this, it’s always been that they have some automated workflow for bringing images in to a catalog or something where the DPI value is read to set the scale. You think that number in the metadata of the .jpg means something for the image quality? It doesn’t. The pixel count is all that matters. The “physical size” of a render means nothing. The physical size of a monitor or projector doesn’t even matter, the average projector is the same or worse than the average monitor.
