0.64 win-x64: Image size is wrong

Post by tboy »

XnViewMP 0.64 on windows 8.1-64 bit
Image size (in centimeters) for thumbnail labels and tooltips is wrong.
For example same file in:
XnView - 16.00 x 21.00 cm
XnViewMP - 15.24 x 20.32 cm
Photoshop - 16.00 x 21.00 cm

File is here as attachment.
Screenshots are made in Windows7-64bit and results are same as in Windows 8 64-bit.
I'm still using XnView-standard more.
Please make xnViewMP menubar detachable and resizable as any toolbar - this will save a lot of space in menu/toolbar rows for minimalistic idiots like me.

Thank you for the exelent XnView.

Thank you for the fast response !

Mr. Pierre,
There is a Zoom command called "Real size" (XnView-Standard).
When I click on it Zoom ratio is set to 38% for a 250 dpi picture.
I think this ratio depends on screen resolution (???).
On my monitor actually it has to be 40% - not 38% as it is by default (monitor calibration is standard and never been changed).
Is there a way to set manually a custom ratio for "Real size" command, .INI settings or something ?
If not - is it possible to add this option in "Settings" for further releases?
May be a custom value for screen resolution will be suitable and will correct "Real size" ratio (???).

Which value of dpi has your monitor?

Registry value HKEY_CURRENT_USER\Control Panel\Desktop - "LogPixels" say:
101 dpi.
This value is automatically chosen by windows 8.1
Monitor is HP L2035 (20,1 inch) 1600x1200 native display resolution.

(This explains the difference 38% -40% in my example If "real size" is based on 96 dpi.)
Is there a way to correct actual DPI settings used in xnView?

Setting Pixel ratio is available in Tools » Settings | View | View.

This problem is supposed to be fixed in current v0.84. Could you please try and confirm the bug fix, tboy?

Pixel ratio is something different.
If I resize an image in Photoshop for example and make it 20cm wide - then when I zoom it to "Real size" in xnView it has to be 20cm wide on my monitor screen - this depends on DPI settings of screen (I think).

In this topic 3 questions exist:
1. Main post was about wrong image size in labels - it was fixed immediately.
2. Next question was about 'Real size' zoom - now it is OK too (less than 1% difference).
3. Pierre said he will add settings for custom correction of DPI - there is something in INI,but I'm not sure & don't know how to use. (may be because I don't need corections now)

@Pierre: Did you add such a setting? Where can this settings be found?
