Method: RBPDF#LinearGradient

Defined in:

lib/rbpdf.rb

#LinearGradient(x, y, w, h, col1 = [], col2 = [], coords = [0,0,1,0]) ⇒ Object Also known as: linear_gradient

Paints a linear colour gradient.

@param float :x

abscissa of the top left corner of the rectangle.

@param float :y

ordinate of the top left corner of the rectangle.

@param float :w

width of the rectangle.

@param float :h

height of the rectangle.

@param array :col1

first color (Grayscale, RGB or CMYK components).

@param array :col2

second color (Grayscale, RGB or CMYK components).

@param array :coords

array of the form (x1, y1, x2, y2) which defines the gradient vector (see linear_gradient_coords.jpg). The default value is from left to right (x1=0, y1=0, x2=1, y2=0).
