Hello,
I'd like to use images of different DPI in my application and print them in correct scale.
But can'not read DPI for attached jpg file.
The file is a screenshot I got from Google map.
The Windows 11 properties window shows the DPI for it = 96.
But in my application I see 300.
my code is like this
iPor.IO.LoadFromFileAuto (pliktlo) ;
showMessage ( inttostr( iPor.IO.Params.DPI )) ;
And I get the message "300"
regards
S. Kowalski

Hi
In the folder that you installed ImageEn, there is a folder named \DLL\. You will find the latest version of the ielib dll in that folder.
https://www.imageen.com/help/ImageEn_DLLs.html
I find it best to create a script that automatically update all DLL in all locations after installing an update.

I'd like to correct my previous message:
when I added to my project the line:
, ieNativeJPEG, ieNativePNG, ieNativeJ2K // Important Compatibility Information (from v14.2.0)
for this test.jpg
- the DPI I get is 120 DPI
- the Windows file details information show 96 DPI
- the Paint application image properties show 120 DPI - as in my project
and I still have the message:
"A required library file iepdf32.dll is older than the minimum supported version the v.140.0.7249"

Hi,
I installed the v.14.2.7 and have no error in compiler in the line
IEGlobalSettings.CopyIEStatusToClipboard();
but in the runtime I get the error message
"A required library file iepdf32.dll is older than the minimum supported version the v.140.0.7249"
and finally the
showMessage ( inttostr( iPor.IO.Params.DPI )) ;
displays 300 DPI
May be the reason is the lack of requested dll version, but I can not find the iepdf32.dll in the download page

OK, you might be using an older version of ImageEn.
Can you clarify whether this is a 32 or 64bit application?
If 64bit, have you added ielib64.dll to your EXE folder?
What is the value of ActivePNGEngine:

Hi,
I have some problem calling it despite I have unit iesettings declared
in the line
IEGlobalSettings.CopyIEStatusToClipboard();
I get the message:
[dcc32 Error] uiePOR.pas(3807): E2003 Undeclared identifier: 'CopyIEStatusToClipboard'
But in the same unit I have other calls like
IEGlobalSettings().DefaultMeasureUnit := ieuMeters;
and this compiles ok

Hi
This is a PNG file rather than a JPEG. When I test it, I get 96 DPI in ImageEn.
Can you call:
IEGlobalSettings().CopyIEStatusToClipboard();
And paste the result into a reply?
