Hi;

How can we select the possition in where ImageEnMView.Acquire will insert the result?.

It seems that after SelectedImage become > -1 it is not possible to set SelectedImage := -1 anymore. Also, it is not possible to set SelectedImage := ImageCount. And if I set SelectedImage := (ImageCount-1) then the image will be inserted before the last one.

So, I can't find how to insert the next aquired page after the last one, when manualy scan pages one by one.

Thank you!

ImageEnMView1.SelectedImage := ImageEnMView1.ImageCount - 1;
If no image is selected (see Deselect) then Acquire will append after the last image.

Yes Bill, thank you, but ImageEnMView.Acquire?. The only way I see is by inserting in OnAcquireBitmap and then set Handled. Right?

To Add a image as the last one use ImageEnMView1.AppendImage.
AppendImage appends a new image at last position in the list and returns the new image position.

To Insert an image before the SelectedImage use ImageEnMView1.InsertImage.
InsertImage inserts a new image at position, idx (where 0 is the first and ImageCount-1 is the last.

You can not set SelectedImage := ImageCount because the ImageEnMView indexes are 0 based, so use ImageEnMView1.InsertImage(index) where the first image index is 0 and the last image index is ImageCount-1.
