I solved the problem... and it was simple...
. Apparently you can draw in image directly to a windows form, but lines and rectangles have to be drawn to a PictureBox... go figure...
Al's ICCA is an Image Capture Composition Aid
. It is a resizable and transparent window you can drag over your image capture window/frame to help you compose your shot.
It produces a grid of line over the capture frame showing the centrelines, diagonals, and the 1/3 frame points (i.e. the corners of the inner rectangle). The "brightness" of the window and lines is adjustable.
Al's ICCA
does not always stay on top like Al's reticle does. If it did, it may obscure some controls on some software and have to be moved to access those controls. By allowing it not to be on top any obscured controls can be accessed as soon as the capture software is brought to focus.
Let me know what you think.
Al.
