+## Display characters
+
+> - Take the character size of `Font16` as an example:
+
+In the main function, call `Paint_DrawString_EN(5, 10, "HELLO", &Font16, WHITE, BLACK);`, and the character `HELLO` can be displayed vertically.
+
+## Display black dots
+
+> - Take the black dot size of 2x2 as an example:
+
+In the main function, call `Paint_DrawPoint(2, 2, BLACK, DOT_PIXEL_2X2, DOT_STYLE_DFT);`, and the black dots can be displayed vertically.
+
+In the main function, call `Paint_DrawPoint(250,122, BLACK, DOT_PIXEL_2X2, DOT_STYLE_DFT);`, and the black dots can be displayed in the lower right corner.
+
+## Display the image
+
+> - Reduce the resolution of the jpg image to 250x122
+
+Run ` resize_image.py ` to get a jpg image with a resolution of 250x122.
+
+> - Convert the jpg format to bmp
+
+In the terminal in the same directory, run the command ` covert input.jpg output.bmp ` to get a bmp format image.
+
+> - Convert the bmp format image to a black and white image
+
+In the terminal in the same directory, run the command ` convert input.bmp -colorspace Gray output.bmp ` to get a black and white image.
+
+> - Modulo the image to get the modulo array
+
+For reference: ` https://github.com/riuson/lcd-image-converter `
+
+Or for simpler images, you can run ` Modulo_array.py ` to get the hexadecimal array and copy the array to the ` ImageData.c ` file
+> - Display the image
+Call ` Paint_DrawBitMap(your arrays); ` in the main function to display the image.
