Ptint
processing
Sets the fill value for displaying images. Images can be tinted to specified colors or made transparent by including an alpha value.
To apply transparency to an image without affecting its color, use white as the tint color and specify an alpha value. For instance, tint(255, 128) will make an image 50pc transparent (assuming the default alpha range of 0-255, which can be changed with PcolorMode).
The value for the gray parameter must be less than or equal to the current maximum value as specified by PcolorMode. The default maximum value is 255.
