Description
Specify the default clipping settings. There are three methods:
A) Tiles, where
nx
,ny
specify to cut the contents intonx
horizontal (ny
vertical) pieces of equal size, andx
,y
choose the piece at x (, y).
B) size/offset, where
width
,height
specify the horizontal (vertical) size of the clipping window, andhoffset
,voffset
: window shift
C) metapost path
mp
: (see example below)
Example
To clip, from page 3 of a PDF, a piece of 60x25, 25 mm from the left edge of the paper and 18+25 mm from the top (assuming A4 paper):
\clip [width=60mm, height=25mm, hoffset=25mm, voffset=\dimexpr 297mm-18mm-25mm\relax] {\externalfigure[file.pdf][page=3]}%
To clip a picture to a circle (from the MetaFun manual):
\startMPclip{circleclip} clip currentpicture to fullcircle shifted (.5,.5) xscaled \width yscaled \height ; \stopMPclip \clip[nx=1,ny=1,mp=circleclip]{\externalfigure[hacker.png]}
