# PDF::API2::Resource::ExtGState(3pm)

Graphics state dictionary support

## NAME

PDF::API2::Resource::ExtGState - Graphics state dictionary support

## METHODS

- $egs = PDF::API2::Resource::ExtGState-\>new @parameters

  Returns a new extgstate object (called from `$pdf`-\>egstate).

- $egs-\>strokeadjust $boolean

  - $egs-\>strokeoverprint $boolean

  - $egs-\>filloverprint $boolean

  - $egs-\>overprintmode $num

  - $egs-\>blackgeneration $obj

  - $egs-\>blackgeneration2 $obj

  - $egs-\>undercolorremoval $obj

  - $egs-\>undercolorremoval2 $obj

  - $egs-\>transfer $obj

  - $egs-\>transfer2 $obj

  - $egs-\>halftone $obj

  - $egs-\>halftonephase $obj

  - $egs-\>smoothness $num

  - $egs-\>font $font, $size

  - $egs-\>linewidth $size

  - $egs-\>linecap $cap

  - $egs-\>linejoin $join

  - $egs-\>miterlimit $limit

  - $egs-\>dash @dash

  - $egs-\>flatness $flat

  - $egs-\>renderingintent $intentName

  - $egs-\>strokealpha $alpha

  The current stroking alpha constant, specifying the constant shape or constant opacity value to be used for stroking operations in the transparent imaging model.

- $egs-\>fillalpha $alpha

  Same as strokealpha, but for nonstroking operations.

- $egs-\>blendmode $blendname

  - $egs-\>blendmode $blendfunctionobj

  The current blend mode to be used in the transparent imaging model.

- $egs-\>alphaisshape $boolean

  The alpha source flag (alpha is shape), specifying whether the current soft mask and alpha constant are to be interpreted as shape values (true) or opacity values (false).

- $egs-\>textknockout $boolean

  The text knockout flag, which determines the behavior of overlapping glyphs within a text object in the transparent imaging model.

- $egs-\>transparency $t

  The graphics transparency, with 0 being fully opaque and 1 being fully transparent. This is a convenience method setting proper values for strokealpha and fillalpha.

- $egs-\>opacity $op

  The graphics opacity , with 1 being fully opaque and 0 being fully transparent. This is a convenience method setting proper values for strokealpha and fillalpha.
