1. Cut and paste one rectangular part of an image from a fixed location using select. 2. Zoom its size by 150% 3. Use CopySelectionToBitmap to grab the BMP. 4. Draw/Paste the BMP back into a cropped copy of the original image.
I now realise that setting zoom:=150 does not alter the underlying image that I initially selected.
Is there an easy way to zoom a selection and grab the bmp?

PS Your online help is very thorough and I thank you for it, but it desperately needs search functionality. I realise you can do this using Google but it's a bit hit & miss. Maybe I should use the .chm!
Can you not just resample the copied selection by the zoom to get the result you want?
i.e. bmp.Resample( ImageEnView1.Zoom / 100, rfLanczos3 );
Sorry about the lack of search functionality. The last release was a bit hurried (due to the simultaneous release of Delphi 13 and my departure for a holiday) and so the search box was not included. It will be back with the upcoming release (in the next week or so).
Moving up to the latest version of ImageEn hasn't been a real problem.
The biggest headache I've found is my new 4K monitor and the changes I've had to make for scaling of old applications with some other components I use.
