Where do I change the image resolution for rendering

I’ve rendered an image as a .png file and when I open it in Fireworks and look at the image resolution I get an 11.something pixels per inch resolution and I need like 200px/inch…

I have not found a way to change this

can someone help me?

thanks in advanced

you mean the pixels/inch

blender doesn’t control that, just the number of pixels per side. Hence fireworks (or photoshop, illustrator, the gimp…) will say the dpi is 72 or 110 (the latter is probably that of your particular display)

you should be able to change that in the gimp or fireworks or most any application. Odd way it works though. You want to scale the image to a different number of pixels/inch with the same number of pixels. It isn’t difficult but it can be odd. in the gimp: image menu->image->scale image
at the bottom part (“Print size and display unit”) change resolution X and Y to 300 (or whatever), notice that the number of pixels doesn’t change on the top half of the dialog. Press OK and your done.

Use a calculator.

I got it, but if I do just that the image looses quality and I want to use it 4 printing

Then use teh calculat0r!

(Hint: you can change the pixel resolution of renders in the Display buttons: SizeX and SizeY. :-))

yep I’ve got that, but lets say I want to render a 1024 x 768 image, so I set the sizeX and Y respectively… the image I get from Blender is 72 px/inch no matter what size you set on the SizeX/Y buttons, it’s resolution remains 72 and I want it to be 200px/inch so if I change it in Photoshop/Fireworks or GIMP it will be stretched out and thus I will get an ugly picture.

they should implement some sort of export dialogue to the F3 function that allows you to determine the resoluition for the image you are exporting, being this independent of the size in pixels …I hope I make myself clear

I don’t understand how it could stretch the picture if you change the DPI. That’s not really logical.
