Provided Methods§

Get an rectangle like selection with specified top left and bottom right edges.

Example
let mut selection = pixel_paper.rect_selection(LeftTopEdge, (3, 3));
selection.apply_color(Black);

Get a copy of a fixed size ( H1*W1 ) section of a PixelsTable.

Example
let copy = pixel_paper.section_copy::<3, 3>(LeftTopEdge);

Cut, Modify, Replace

Modify a fixed size ( H1*W1 ) section of this PixelsTable separately and in place.

Example

Modify a 3*3 cut starting from LeftTopEdge as a separate Canvas.

pixel_paper.modify_section::<3, 3>(LeftTopEdge, |canvas| {
    canvas.change_pixel_color(RightBottomEdge, Red);
});
