Trying to Scroll an image - Sprites, Drawpixels, or just PushImage?

[Pajservices]

Hi there, your library is awesome and I've used it for a number of applications.

However, I'm now trying to get an image to scroll across the screen, on a ESP32 BOX.

The images are 160 high x 320 wide - and the screen is 240 x 320.
I want it to start from the right hand side and display column by column across to the left - giving the impression of scrolling in and then disappearing from the left.

I initially tried in a convoluted way by a few loops that displayed image column 1 in screen column 320; then image col1 and 2 starting in screen 319 & 320; then 1, 2 ,3 in 318, 319, 320 ...etc...get the idea - very messy and very slow.

Also tried Pushimage of the whole image into the screen starting at right hand column - this just trashed memory.

I'm now trying to use sprites - maybe pushing columns at a time to the sprite and then that to the display - but struggling a little with fully understanding how they work.

Any help would be very gratefully received.
