Name
push()
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()
,
strokeWeight()
,
strokeCap()
,
strokeJoin()
,
imageMode()
,
rectMode()
,
ellipseMode()
,
colorMode()
,
textAlign()
,
textFont()
,
textMode()
,
textSize()
,
textLeading()
.
The
push()
and
pop()
functions were added with
Processing 3.5. They can be used in place of
pushMatrix()
,
popMatrix()
,
pushStyles()
, and
popStyles()
.
The difference is that push() and pop() control both the
transformations (rotate, scale, translate) and the drawing styles
at the same time.
Examples
-
fill(255); rect(0, 0, 200, 200); // White rectangle push(); translate(80, 70); fill(0); rect(0, 0, 200, 200); // Black rectangle pop(); // Restore original settings fill(100); rect(40, 40, 200, 200); // Gray rectangle -
ellipse(0, 200, 133, 133); // Left circle push();
