Hi,

I need to load an image to a predefined space (e.g. 600x450 px) and add some image and text layers.

Questions:

1.) Is it possible to show in ImageEnView only the predefined area and hide those parts of a layer/background image which is excessing the predefined area?

2.) When saving as JPG, is it possible to save only those parts of the content which is located on the predefined area?

Hi Al

1. Do you mean like:

https://www.imageen.com/help/TImageEnView.VisibleBitmapRect.html

2. You would need to copy it to another bitmap, e.g.

// Save the visible bitmap in ImageEnView1 to JPEG
bmp := TIEBitmap.Create;
bmp.Allocate( IERectangle( ImageEnView1.VisibleBitmapRect ).Width,
              IERectangle( ImageEnView1.VisibleBitmapRect ).Height );
ImageEnView1.IEBitmap.DrawToTIEBitmap( bmp, 0, 0, IERectangle( ImageEnView1.VisibleBitmapRect ));
bmp.Write( 'D:\im.jpg' );
bmp.Free;

Hi Nigel,

ad 1) solved with:
ImageEnView1.SoftCrop := iesfAlphaBlend;
ImageEnView1.SoftCropValue := 30;

ad 2) solved with
ImageEnView1.LayersCropped := True;
ImageEnView1.LayersMergeAll();
ImageEnView1.IO.SaveToFile(FileName);



Perfect for me. : )
