= imageData() =
== Description ==
Returns the pixel data array of a [[GSDP:GAM100/CProcessing/PImage |PImage]] if it was created with the CP_IMAGE_STORE_PIXEL_DATA set by * [[GSDP:GAM100/CProcessing/setImageFlags() |setImageFlags()]]

==== Parameters ====
imageCreateTint(PImage img)

*img - ([[GSDP:GAM100/CProcessing/PImage |PImage]]) The image to extract the pixel data from.

== Example ==
<syntaxhighlight lang='c'>
PImage justin_face;
PImage tinted_justin_face;
int x_size, y_size;

void init()
{
setImageFlags(CP_IMAGE_STORE_PIXEL_DATA);
justin_face = loadImage("./Assets/justin1.png");
tinted_justin_face = imageCreateTint(justin_face, color(255, 0, 0, 255));
x_size = imageWidth(justin_face);
y_size = imageHeight(justin_face);
}

float rotation = 0;
void update()
{
background(color(255, 255, 255, 255));
imageRotated(tinted_justin_face, mouseX, mouseY, 100, 150, 255, rotation);
rotation++;
}
