Hello,
I'd like to make a snapshot of the sreen/window/area at run time form my PhAB C apllication. I bulid an HMI and I want to add new integrated functionality for users to make a screenshot of current data on the screen. As I found it was easy to do it in QNX 4.25 with snapshot command (with relevant options) e.g.:
snapshot -A 100*100 -o 50*50 -p "BMP Spool File" -f /src/photon/apps/print1.bmp
But in QNX 6.3 version it doesn't work by this way.
Could you give me a tips how to do it by code, please?
Thans, Meg |

The parameters given to snapshot are just for the GUI-App Snapshot, so not a direct screenshot.
I don´t think there is anythink like the old console-driven-snapshot possible, unless you write your
own shot-app |

I think you would need to open a memoryContext and Copy your current DC into it, where the DC is the MAIN-Screen
I do right now do not have the time to check this, but i will try this soon i guess  |
