First time with LEDMatrix library. Text upside down [solved]

Hi,

I have just started playing with the LEDMatrix library and the characters are appearing up-side-down.

I am using a 20 x 7 matrix of WS2812B LEDS. The matrix is set up non-snake with the first LED at top left:

// 0 > 1 > 2 > 3 > 4
// |
// .----<----<----<—’
// |
// 5 > 6 > 7 > 8 > 9
// |
// .----<----<----<—’
// |
// 10 > 11 > 12 > 13 > 14
// |
// .----<----<----<----’
// |
// 15 > 16 > 17 > 18 > 19

Aaaron does state that the matrix should start at botton left but I had already built it before seeing his comment

I am using the example sketch, TextExample1, with left scroll only.
const unsigned char TxtDemo = { EFFECT_SCROLL_LEFT " LEFT SCROLL " };

The text is scrolling ok but all the characters are up-side-down, for the life of me I cannot figure out how to change, is there a way to reverse it?

Found the solution. It is built in to the library, just need to add a minus before the matrix height.
