push()

The push() function saves the current drawing style settings and transformations, while pop() restores these settings.

Examples

def setup():
    py5.fill(255)
    py5.rect(0, 0, 50, 50)  # white rectangle

    py5.push()
    py5.translate(30, 20)
    py5.fill(0)
    py5.rect(0, 0, 50, 50)  # black rectangle
    py5.pop()  # restore original settings

    py5.fill(100)
    py5.rect(15, 10, 50, 50)  # gray rectangle

def setup():
    py5.ellipse(0, 50, 33, 33)  # left circle

    with py5.push():
        py5.translate(50, 0)
        py5.stroke_weight(10)
        py5.fill(204, 153, 0)
        py5.ellipse(0, 50, 33, 33)  # middle circle

    py5.ellipse(100, 50, 33, 33)  # right circle

Description

The push() function saves the current drawing style settings and transformations, while pop() restores these settings. Note that these functions are always used together. They allow you to change the style and transformation settings and later return to what you had. When a new state is started with push(), it builds on the current style and transform information.

push() stores information related to the current transformation state and style settings controlled by the following functions: rotate(), translate(), scale(), fill(), stroke(), tint(), stroke_weight(), stroke_cap(), stroke_join(), image_mode(), rect_mode(), ellipse_mode(), color_mode(), text_align(), text_font(), text_mode(), text_size(), and text_leading().

The push() and pop() functions can be used in place of push_matrix(), pop_matrix(), push_style(), and pop_style(). The difference is that push() and pop() control both the transformations (rotate, scale, translate) and the drawing styles at the same time.

This method can be used as a context manager to ensure that pop() always gets called, as shown in the last example.
