Hi,
after cropping and saving, a white line appears at one of the borders of the saved image (PNG, JPG). In case of a horizontal crop the white line is at the right border of the image, in case of a vertical crop at its bottom.
The line doesn't appear in the ImageEnView.
In order to avoid the line, I like to specify the BitmapPolygon coordinates in the crop function, e.g.:
ImageEnView1.CropTool.Enact(x1, y1, x2 -1, y2 -1);
Now, after showing the CropGrid on the image, an user could modify its position manually. How do I get the current BitmapPolygon coordinates in order to decrease the x2 and y2 values before cropping?

Hi Al
I can't reproduce the border issue in the CropTool demo (with 9.1.1). Can you give me the exact steps.

Hi Nigel,
my mistake. I set the BitmapPolygon rect(0, 0, bmp.width, bmp.height) instead of rect(0, 0, bmp.width -1, bmp.height -1). In fact, if the grid is drawn manually inside the image, the behaviour is correct in my tool as it is in the CropTool demo, thus no white line will be added. I just corrected my app and it works fine now.
