Ideally I'd like to save the overlay without the background. I understand to erase an image with a white background using a white pen, but not sure how to do this using transparent images, and how to save them as transparent. I'm using the 'Notes' demo app that comes with Windev to test, and have added a base image under the drawing image, and some code to hide/show the base image on the control, but the two images are merged after the first draw. I expect the users to need to correct mistakes frequently - maybe a 'undo' button would be better than erase. Thanks for any tips Pete30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/56538-20-draw-over-background-image-separate-layer/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/56538-20-draw-over-background-image-separate-layer-56635/read.awp27 Feb 2016 11:48:00 ZHi Steven, No I didn't, sorry...
