Spent some time on another amazing addition to freeware. If this would work correctly, I don't really see a need for the "Set DPI" dialog.I was looking for a program to really dig into and learn and this was just the ticket. Hm, thinking about it, it should be considered a bug. But if you uncheck the box and then change the PPI, the same happens! The print size remains unchanged and the pixel size changes. However, it does not work perfect: if you change PPI with the checkbox checked (thus keeping the print size) it will do what you expect – the pixel size is changed. In XnViews "Resize image" there is a similar checkbox called "Keep print size", which should function just as Photoshops "Resample image" I imagine. Therefore Photoshop does not need two different dialogs, you can do it all in "Image size". Very handy and gives total control over PPI/pixel size/print size. When checked the pixel size is changed, when unchecked the print size is changed. You can, under "Image size" (the Photoshop equivalent to XnView's "Resize image") you can use the check box "Resample image" to toggle between resizing print/pixel-size when changing PPI. You can't even do that in Photoshop directly IIRC. Ah, maybe its a question of taste?ĭanny wrote:But remember that the current functionality would be lost (change PPI -> resize image, but keep print size). Its more pedagogic too, isn't it? Change of DPI should not affect the actual pixels of the image, because such an action will resize the image (yes, even in the "Resize" dialog ). I suggest it works like in the "Change DPI" dialog in both dialogs = print size is affected. I was quite suprised when I discovered this difference. If I change DPI in one of the dialogs, I would take for granted it would work the same in the other dialog, when changing the same value. 1.A I don't see what's supposed to be inconsistent. In "Set DPI", the printsize changes instead. If you change DPI in "Resize", the pixelvalues change as compensation. We could even have a setting for LPI (lines per inch) in there as well.Ī. Like i said before, it's ok with me to have a seperate "Change print size" dialog. Dots is what your printer spits out, which is something completely different (don't get me started ). XNView is the only program i know that's treating x and y differently btw.Īpart from that, it should be called PPI anyway, 'cause that's what they really are - pixels. Change DPI dialog -> only affects print size, no pixels are changed.ġ.B Good question.In "Set DPI" you can change X and Y individually, but not in "Resize"? Why? 1.A I don't see what's supposed to be inconsistent. Troken wrote:The only reason to keep the "Set DPI" dialog would be for those who are not accustomed to the "Resize"-dialog yet.ī. So this issue unfortunately has many side effects. Suddenly the image that you thought had 720 dpi gets 'distorted' and very thin, even if this actually is the correct view. This can become troublesome in the "Print" dialog as well, if you select "Single - DPI". Now the image in our example will be shown correct - very thin. go to "Paint" and cancel, to update the image view. Inconsistent if you ask me, and very confusing.Īnd a bug: the image is not updated with this new dpi (720/72), it still looks like 72/72 dpi. So with this in mind, take this strange example: What happens if you in "Set DPI" change the X value only, say from 72 to 720 dpi? Now look in "Resize", the overall DPI is set to 720 (XnView choses to display the X DPI only, not the Y DPI). In "Set DPI" you can change X and Y individually, but not in "Resize"? Why? We can start with the funny thing how different the "Set DPI" dialog and the "Resize" dialog works:Ī. When reading this old post again, it appears to me that the problem gets more serious. The only reason to keep the "Set DPI" dialog would be for those who are not accustomed to the "Resize"-dialog yet. Yes, some kind of feedback for the user would be nice. Thank you Danny for adressing this issue again. Danny wrote:IMO it can stay in it's own dialog, but there's got to be a feedback on the print size changes.
