I use
ImageEnIO->LoadFromFile
or
ImageEnIO->ParamsFromFile
and see
ImageEnIO1->Params->DpiX = 300
real DpiX = 200

I see the 200 value in AcdSee, FastStone, Corel ...

Why?

When I write "on-loading" I include also the case of loading parameters only. So, I repeat, it is not possible.
Of course you can still write your code to read the jpeg header, but this is out of topic, I'm sorry.

How to get the resolution value from header of JPG file BEFORE LOADING?

Now it is not possible, I'm sorry. The EXIF-dpi just overwrites the jpeg-headder value on loading.

Thanks.

New version of ImageEn is not free?

This image has two DPI info stored.
One is inside the jpeg-header and one in the EXIF metatags.
The jpeg-header contains the 200 dpi value, which is the value showed by other programs.
The EXIF metatags contain the 300 dpi value. ImageEn select this value, as you can see.

Because it is more common to select the jpeg-header value then the next release of ImageEn will follow this way also, so it will show 200 dpi as other softwares.
