Show Image
Show an image (picture) on the LED screen. After the @boardname@ shows an image, it will pause for 400 milliseconds (1000 milliseconds is one second).
let item: Image = null;
item.showImage(0);
Parameters
- an image (picture). It is usually a square with five LEDs on a side, but it might be wider.
- a number that says how many LEDs from the left of the picture the @boardname@ should start.
0means start at the first frame of the picture,5means start at the second frame,10means start at the third, and so on.
Example: Flip-flopping arrow
This program makes a big image with a frame of an arrow pointing up,
and a frame of an arrow pointing down. If you press button A, the
program will use show image to show the arrow pointing up. (It
starts 0 LEDs from the left in the big image.) If you press button
B, the program will use show image to show the arrow pointing
down, which starts 5 LEDs from the left.
let arrows = images.createBigImage(`
. . # . . . . # . .
. # # # . . . # . .
# . # . # # . # . #
. . # . . . # # # .
. . # . . . . # . .
`);
input.onButtonEvent(Button.A, ButtonEvent.Click, () => {
arrows.showImage(0);
});
input.onButtonEvent(Button.B, ButtonEvent.Click, () => {
arrows.showImage(5);
});
