DK-TM4C129X: Screenshot of the user interface created using GrLib

Part Number: DK-TM4C129X

Hi Engineers,

I've used TI GrLib on TM4C129X Connected Development Kit. I need to take some screenshots of my user interface.

I am not sure about the internal workings of the GrLib. I think this can be achieved by copying the display buffer into a raw binary file and retrieve its content using software like Fiji. Is this the correct way to go ? If so could anyone point which part of GrLib needs to be updated so as to access the screen buffer ?

Is there any other alternative way to get clean looking screenshots ? I do not prefer to take pictures using a camera as the quality is bad when printed.

Thanks

    Hello Cheery

    The GrLib works by writing directly to the frame buffer in the Panel. There is no method to retrieve the data from the panel in the GrLib.

    In light of vendor Amit's response - and acknowledging "extra" time/effort - firm/I have done such via "simple, commercial Graphic programs."
    Note too the (rather severe) color limitations of vendor's GrLib - which is avoided via your use of a superior Graphic program - intended for printing.
