Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Has anyone noticed this before?
I have an ILI9341 LCD panel set up in LANDSCAPE mode (320x240). If I do:

LINE 0,0,100,0
I get the expected top row horizontal line (along the screens long axis).

Now, trying out the GUI BITMAP command which has the format:
GUI BITMAP X, Y, BITS, WIDTH, HEIGHT, SCALE, C, BC (the last five parameters can be defaulted)

If I do:

x% = 1
GUI BITMAP 0,0,x%
I get the expected single pixel in the 8th position on the top row. Note that the width and height parameters are defaulted, i.e. 8,8 i.e. a square region.

If I do as above but change the width and height parameters to 32,1 i.e.
GUI BITMAP 0,0,x%,32,1
I get a single pixel in the 8th position down the screen (along the short screen direction).

Question is - should the WIDTH and HEIGHT parameters be swapped in landscape mode or is this a bug? If the former, then we need a note to that effect on page 22 of the Manual and the same in the command definition table.

This is definitely a bug - I've reported it to Geoff offline
