When opening TOpenImageEnDialog on a secondary monitor that has different scaling than the primary, the dialog appears as shown in the attached image.
I spent a little time stepping through the code but did not find the cause. Even setting a data breakpoint on FLeft for the ImageEnView and ImageEnMView did not reveal the source of the issue. I am not experienced with coding for HighDPI. However, neither of these monitors are using HighDPI.
Primary desktop is set at 125% (Recommended) scaling and secondary desktop is set at 100% (Recommended) scaling. If I set the secondary desktop to 125%, the dialog looks as expected on the secondary monitor.
ImageEn 11.4.5. I have 12.0 downloaded but have not installed it yet.
Thanks |

Hi Jon
I cannot reproduce that in 12.0.0, but there are often quirks related to VCL scaling.
You might prefer to set ModernDialog to true to use the Windows dialogs instead.

I updated to 12.0.0 and the issue still occurs on my dev laptop. I am currently the only person running this version of our app, so I don't know whether would occur for any of our users.
Since I am calling ImageEnMView.MIO.ExecuteOpenDialog and not a TOpenImageEnDialog directly, I tried setting IEGlobalSettings().UseWindowsOpenSaveDialogs := True; That works and shows the Windows dialog. I do prefer the preview of the ImageEn dialog. I will try to spend more time on the scaling issue once our next release is finished.
Thanks Nigel.

Hi Jon
I can't reproduce that, but the ImageEn dialog is built on an older Windows control, and it doesn't cope well with per-monitor scaling, so you are better to use the ModernDialog option.
Also, ensure you are using "Per Monitor v2" DPI awareness.

We are using Per Monitor v2, although I didn't know it. I've been in Unix/Linux working environments the past couple of years so these DPI issues are new to me. ;)
Thanks for a little education. ;)
