I have a question:
I need to supply custom bitmaps for the TImageEnMView control.
Is there a way to find out exact Width and Height of the bitmap within the dimensions of the thumbnail, taking into the account border and style settings, to avoid stretching/distortion of the bitmap.
I am using OnImageIDRequest event and it would be convenient to have pre-calculated Width and Height as incoming parameters to the event, so that bitmap can be created with exact measurements and displayed as is by the control.


Thanks,

Eugene

Hi

Please use:

https://www.imageen.com/help/TImageEnMView.ThumbSizeInfo.html

ThumbSize := ThumbSizeInfo( itsImage );


Explanation of ThumbSizeInfo Data param:

Here is a filled TImageEnMView:

_[o]_[o]_[o]_[o]_
_[o]_[o]_[o]_[o]_
_[o]_[o]_[o]_[o]_
_[o]_[o]_[o]_[o]_

itsImage: Just the thumbnail "o"
itsCell: Just the thumb cell "[o]"
itsOuter: Cell and the spacing around it "_[o]_"
