SHOW_IMAGE

Purpose

To show a bitmap image on the LCD.

Syntax

SHOW_IMAGE(x%, y%, size_x%, size_y%, image$)

Remarks

"x%" is an integer variable, indicating the x coordinate of the upper left point of the

rectangular area.

"y%" is an integer variable, indicating the y coordinate of the upper left point of the

rectangular area.

"size_x%" is an integer variable, indicating the width of the rectangular area in

pixels.

"size_y%" is an integer variable, indicating the height of the rectangular area in

pixels.

"image$" is a string variable, containing the bitmap data of the image.

The user needs to allocate a string variable to store the bitmap data of the image.

The string begins with the top row of pixels. Each row begins with the left-most

pixels. Each bit of the bitmap represents a single pixel of the image. If the bit is set

to 1, the pixel is marked; if it is 0, the pixel is unmarked. The first pixel in each row

is represented by the least significant bit of the first byte in each row. If the image is

wider than 8 pixels, the ninth pixel in each row is represented by the least significant

bit of the second byte in each row.

Below is an example of the company logo and the string variable - icon$, which is

used to store the bitmap data.

1 2 ... 90 91 92 93 94 95 96 97 98 99 100 ... 197 198
