option

description

antialias

(Boolean) Specifies whether to activate antialiasing for the shading. Default: false

boundingbox

(Rectangle) A rectangle defining the shading’s bounding box in user coordinates. The bounding box will be applied as a temporary clipping path when the shading is painted (in addition to the current clippingpath which may be in effect). This option may be useful to clip the shading without applying PDF_clip( ).

Default for PDF_shading( ): no clipping

Default for the shading graphics appearance option: the matchbox or table cell rectangle

end

(List of 2 floats or percentages; not for PDF_shading( )) Coordinates of the ending point (for type=axial)or a point on the ending circle (for type=radial), specified as percentages of the rectangle’s width and height or in user coordinates. Default: {100% 100%}

endcolor

(Color; ignored if stopcolors is supplied; one of the options endcolor and stopcolors is required for the shading graphics appearance option) The shading’s end color. Default for PDF_shading( ): the last color provided in the stopcolors option if specified, otherwise the values supplied in the parameters c1, c2, c3, and c4

extend0

(Boolean) Specifies whether to extend the shading beyond the starting point or circle. Default: false

extend1

(Boolean) Specifies whether to extend the shading beyond the ending point or circle. Default: false

N

(Positive Float) Exponent for the color transition method. Default: 1

r0

(Float; only for type=radial) Radius of the starting circle in user coordinates. Default: 0

r1

(Float; only for type=radial) Radius of the ending circle in user coordinates. Default for PDF_shading( ): 

0. Default for the shading graphics appearance option: distance between start and end

start

(List of 2 floats or percentages; not for PDF_shading( )) Coordinates of the starting point (type=axial) or the center of the starting circle (type=radial), specified as percentages of the rectangle’s width and height or in user coordinates. Default: {0% 0%}

startcolor

(Color; ignored if stopcolors is supplied) The shading’s start color. Default: the first color provided in the stopcolors option if specified, otherwise the color specified in the option fillcolor for the matchbox or table cell

stopcolors

(List of pairs; one of the options endcolor and stopcolors is required for the shading graphics appearance option) List of two or more colors for the shading. Each pair contains a float value or a percentage

for the position of an intermediate shading color in the inclusive interval 0...1 and the corresponding color value. All color values must use the same color space except for spot colors with Lab alternate colors as described in the Details section above. The positions must be sorted in ascending order, but adjacent position values may be identical. If no value for position 0 is present the first list entry is used; if no value for position 1 is present the last list entry is used. If this option is supplied the options startcolor and

endcolor, the parameters c1,...,c4 and the current fill color are ignored. Examples:

stopcolors={0 red 0.4 magenta 0.75 green 1 black}

stopcolors={0% {cmyk 1 0 0 0} 33% {cmyk 0 0.4 0.3 0}} 100% {cmyk 0 0 0.2 0.8}}

stopcolors={0% {spotname {PANTONE 123 U} 1} 100% {spotname {PANTONE 289 U} 1} }

type

(Keyword) Shading type: axial for a linear shading or radial for a circle-like shading. Default: value of the parameter type if present (only for PDF_shading( )), otherwise: axial
