One graphicx transformation, as compiled from the option string.

Port of the @transform list Perl image_graphicx_parse builds (Util/Image.pm L142-196). Lengths are in bp, the unit to_bp yields, and angles in degrees counter-clockwise, as graphicx states them.

Variants

Page(u32)

page=N — which page of a multi-page source to take.

Trim

trim=l b r t — amounts to remove from each edge.

Fields

l: f64

b: f64

r: f64

t: f64

Clip

viewport=llx lly urx ury — an absolute box (Perl’s clip op).

Fields

l: f64

b: f64

r: f64

t: f64

Rotate(f64)

angle=N, counter-clockwise.

Reflect

Scale

scale=/xscale=/yscale=.

Fields

x: f64

y: f64

ScaleTo

width=/height=/totalheight=. A dimension left None is derived from the other through the aspect ratio; Perl spells that as a 999999 sentinel with keep_aspect forced on (L188-189).

Fields

w: Option<f64>

h: Option<f64>

keep_aspect: bool
