new image dialog not userfriendly


Recommended Posts

Hi,

if i want to make a new picture of defined size, i change the print size to xy cm. Then i raise the resolution to a higher px/cm ratio. After that, the defined size in cm is lost/changed.

Perhaps pdn should remember which field (px or size) has changed last and lock this value if changing px/cm ratio.

Thanks a lot

Holger

Image size and the DPI are intrinsically linked. You can't change one without affecting the other.

This should help explain: DPI and you

> Why was this posted in Troubleshooting?

Thanks for the moving the thread. I thought this was the correct place, since my girlfriend had a trouble with ugly fonts after printing, due to too low resolution. 8-)

> Just remember to set the resolution before the print size.

I titled the post "not userfriendly" with a reason.

The problem to solve is: I want to make an image to look nice when printed at a photolab on photopaper with 10x15cm². Homemade greeting card for example. There the main parameter are the size on paper and the dpi value. I do not care how many pixel this will be.

So it would be nicer if it would make no different which of the two options (size on paper and dpi) i enter first. I did not said, that PDN do it wrong, but how it could be improved for unexperienced users.

> Image size and the DPI are intrinsically linked

I know that pixel count and printed size is linked through DPI, but pixel count is sometimes really nonrelevant.

The size on paper is calculated from the pixel size and DPI. Not the other way around.

Print Width = Pixel Width * DPI

All you need to do is adjust DPI (resolution) until the print size matches what you want.

Very relevant, as Rick explained above. Trying to ignore one half of the equation as 'nonrelevant' is not going to make it go away.

Do i write in chinese...? :-)

The equation is converted valid, too:

Pixel Width = Print Width / DPI

Very relevant, as Rick explained above.

Perhaps not nonrelevant for the programm, but for the user to solve the problem.

Nonrelevant in the term of: I do not care which pixel size the picture will get. But i want a 10cmx15cm print with 300 dpi, so PDN should calculate the pixel size regardless which of my two (dpi, print width) i enter first.

I hope this is now clear. Thanks :-)

If you're going to continue being cranky and argumentative then there's no reason for us to try and talk you down. You've got the facts, now go use them in a productive manner that doesn't waste our time.
