Hello, how can I check if an image is in Portrait or Landscape format and adjust it to display?
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
Button2Click
(
Sender
:
TObject
)
;
var
Fit
:
Single
;
begin
Fit
:
=
ImgView32_1
.
Height
/
ImgView32_1
.
Bitmap
.
Height
;
ImgView32_1
.
Scale
:
=
Fit
;
end
;
Width code
Code: Pascal
[Select]
[+]
[-]
Fit
:
=
ImgView32_1
.
Width
/
ImgView32_1
.
Bitmap
.
Width
;
How to connect together?

ShowMessage
(
'Portrait'
)
else
ShowMessage
(
'Landscape'
)
;
Fit
:
=
ImgView32_1
.
Height
/
ImgView32_1
.
Bitmap
.
Height
;
if
Fit > ImgView32_1
.
Width
/
ImgView32_1
.
Bitmap
.
Width
then
Fit
:
=
ImgView32_1
.
Width
/
ImgView32_1
.
Bitmap
.
Width
;
end
;
You can also set
ScaleMode
to smOptimal or smStretch and then the size will be automatically adjusted:
