Could be cool to have a print size calculator based on a DPI input in the output panel.
Re: DPI to Pixel
Nice idea. I always use Ps to calculate it.
Re: DPI to Pixel
Me some times too, but If you own a Rhino license (Cheap), a V-Ray license (Cheap) I don’t think I can Spend more money in a Photo retouch Software just to calculate de DPI, (I use PS fo that porpouse to retouch renders) use a software that it’s free called “DPI to pixel” google it. 
Re: DPI to Pixel
No need to use PS to calculate this. It’s easy math.
sizeInInch * DPI = pixelSize
And there’s an array of online tools, like this: Stock Photos, Vectors and Royalty Free Images from 123RF
Re: DPI to Pixel
yeah we know that, but it would be cool to have a interface like PS to have a DPI slot qere if you change the values they autoupdate.
