UTFT read screen

Anyone know if it is possible to read what is on a UTFT display at a particular location....

I could do with reading either the whole screen or a section of it so that I can put it back after a pop up has appeared.

Im using the SSD1963, CTE 7" display using same pin outs as CTE use on their shields....

use the GLCD.print("..."); method that wrote the text in the first place just call it after the popup... AFAIK there is no way to 'read' the display and If there were, You would STILL have to print it again So. What are you saving.. If you are printing variables that might change then call the method that printed the changes data.

I didn't think that there would be but it was worth a check. I'm writing a library which will not know what it is overwriting. There are ways round it but it just makes it more complicated.

How? you know what was there originally and where it’s at… just refresh the overwritten data. It works for me and I have about 4 of those displays in use.

I am writing a GUI with pop up touch screen keyboard etc. The library pop up routines will not know what has been draw but I have had a think about the way I am doing everything and will have objects for everything on screen so I can cycle through them redrawing any that have been overwritten. Being able to read the screen would just have made things simpler especially if I were to implement a mouse pointer.
