- Dear whoever.
-
- I am trying to write a bitmap routine that updates from a constantly
- changing source (ie a live camer feed) to a windows (windows 3.11 16 or
- 32 bit ). I know how to do this in
- principle. However I would also like to be able to overlay on this image
- a set of croos hairs (not too difficult) but more importantly a scale
- along the side (in mm)
- ie something like below.
-

- 1mm -********************

- 4mm -********************
- ********************
- 5mm -********************
- ' ' ' ' ' '
- 1mm 2mm 3mm 4mm 5mm 6mm
-
- The asterix area needs to be the update from the live image feed (256*256
- pixels). However the scale will never change (unless the zoom option is
- used). How can I get something like this to work
-
-
- Anyhelp is greatly appreciated
