zuse Posted November 8, 2010 Share Posted November 8, 2010 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 Link to comment Share on other sites More sharing options...

Ego Eram Reputo Posted November 8, 2010 Share Posted November 8, 2010 Image size and the DPI are intrinsically linked. You can't change one without affecting the other.

zuse Posted November 15, 2010 Author Share Posted November 15, 2010 > 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.

Rick Brewster Posted November 15, 2010 Share Posted November 15, 2010 There the main parameter are the size on paper and the dpi value. I do not care how many pixel this will be. 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.

Ego Eram Reputo Posted November 15, 2010 Share Posted November 15, 2010 ....pixel count is sometimes really nonrelevant. Very relevant, as Rick explained above. Trying to ignore one half of the equation as 'nonrelevant' is not going to make it go away. ebook: Mastering Paint.NET | resources: Plugin Index | Stereogram Tut | proud supporter of Codelab plugins: EER's Plugin Pack | Planetoid | StickMan | WhichSymbol+ | Dr Scott's Markup Renderer | CSV Filetype | dwarf horde plugins: Plugin Browser | ShapeMaker Link to comment Share on other sites More sharing options...

Print Width = Pixel Width * DPI All you need to do is adjust DPI (resolution) until the print size matches what you want. 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.

Rick Brewster Posted November 19, 2010 Share Posted November 19, 2010 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.
