Hm... Then it could be the dpi. The dpi is definitely different in the lab and in the office. There is no way around to have the points displayed correctly on different screens?
Good news. I finally found a solution for the PictureSnap screen DPI issue when displaying stage coordinates on an image, that was acquired on a monitor with a different screen resolution. It is now fixed.
Basically this is the Windows screen resolution parameter when, under Win 7, you right click the desktop, select the Screen Resolution menu, select the Make Text and other items larger or smaller link, and select one of the options. Usually one will see 100% (the default), 125% and 150%.
The new PictureSnap code saves this screen resolution DPI to the .ACQ file (along with the other calibration parameters) when the image is saved. When the image (in PictureSnap) is displayed on another monitor, the new code adjusts the screen calibration so the image and the stage coordinates are properly displayed.
This code will work on all ACQ files generated since 6/29/2017 (v. 11.9.4). If you have an older ACQ file, simply re-generate the ACQ file by exporting it again, or by re-running the calibration on the original computer/monitor. The ACQ file will be updated properly with v. 12.1.0 or higher of PFE.
Alternatively one can simply edit the old ACQ file for the new parameter as seen here:
[stage]
PictureSnap mode="0"
Number of calibration points="2"
Number of Z calibration points="0"
Screen reference point1 (twips)="7680,7680"
Screen reference point2 (twips)="0,0"
Stage reference point1="50.2185,50.6295"
Stage reference point2="50.4815,50.3705"
X_Polarity="-1"
Y_Polarity="-1"
Stage_Units=mm
ACQScreenDPI="1"
Where the ACQScreenDPI is the DPI of the monitor that the image was acquired on, and 1 = 100%, 1.25 = 125% and 1.5 = 150%. So just edit the ACQ file in any text editor for the DPI of the system it was acquired on and save the file. It should then load fine in PictureSnap on any DPI monitor now.
Odd that this different DPI monitor issue only showed up in PictureSnap, not any other places where stage coordinates are plotted on images. And sorry it took me so long to find a solution, it was actually pretty simple once I understood the problem. Thanks.
