Struct TestImage

Source
pub struct TestImage<C: RgbColor> { /* private fields */ }
Expand description

Test image.

The test image can be used to check if the display is working and to identify the correct orientation and color settings.

§Expected output

Note that the gray border around the image above is only added to make the white border visible on the light rustdoc theme and will not be visible when the test image is drawn.

  • There should be a one pixel white border around the display.
    Modify the display size and display offset settings, if at least one edge of the white border isn’t drawn or if there is a gap between the white border and the edge of the display.
  • A white triangle should be drawn in the top left corner and the RGB label text should not be mirrored.
    Modify the orientation setting to rotate and mirror the display until the test image is displayed correctly. Note that the white triangle might not be visible on displays with rounded corners.
  • The colored bars should match the labels.
    Use the color inversion and color order settings until the colored bars and labels match.
