Drawing PNG, JPG and BMP files from the microSD card

Let's draw the example images of different formats on Inkplate, download them from the Inkplate library and place them in the root folder of the microSD card:

Let's draw image1.png at coordinates 0, 0 and using the display.drawImage() function:

// Make sure Inkplate and then the microSD card are initialized before this
if (!display.drawImage("image1.bmp", 0, 0, 1))
    {
        // If is something failed (wrong filename or wrong bitmap format), write error message on the screen.
        // REMEMBER! You can only use Windows Bitmap file with color depth of 1, 4, 8 or 24 bits with no
        // compression! You can turn of dithering for somewhat faster image load by changing the last 1 to 0, or
        // removing the 1 argument completely
        display.println("Image open error");
    }
display.display();

Now, lets draw image2.bmp by frst loading it using SdFat library class and then displaying it on epaper:

if (file.open("image2.bmp", O_RDONLY))
        {
            display.drawBitmapFromSd(&file, 0, 0);
        }
        else
        {
            display.println("Image open error");
        }   
        display.display();

Lets try another file format, for example, jpg:

if (!display.drawImage("pyramid.jpg", 100, 0, true, false))
        {
            // If is something failed (wrong filename or wrong format), write error message on the screen.
            // You can turn off dithering for somewhat faster image load by changing the fifth parameter to false, or
            // removing the parameter completely
            display.println("Image open error");
        }       
        display.display();

inkplate.drawImage()

Function draws image from char path.

Returns value: Returns true if image was successfully drawn, otherwise false.

Function parameters:

Type	Name	Description
const char*	path	Path and filename of the image. Can be a URL (for web images) or a file path (on the microSD card).
int	x	X-coordinate of the image's upper-left corner in the framebuffer.
int	y	Y-coordinate of the image's upper-left corner in the framebuffer.
uint8_t	dither	Dithering mode: 0 (disabled), 1 (enabled).
bool	invert	If true, inverts colors.
