drawPng draws one PNG image at the given locations and sizes.
drawPng(png_file,
xleft, ybottom, xright, ytop,
angle = 0, ...)
png_file |
a character string giving the name of the PNG file |
xleft |
a real value for left x positions. |
ybottom |
a real value for bottom y positions. |
xright |
a real value for right x positions. |
ytop |
a real value for top y positions. |
angle |
angle of rotation (in degrees, anti-clockwise from positive x-axis, about the bottom-left corner). |
... |
graphical parameters. |
The positions supplied, i.e., xleft, ..., are relative to the
current plotting region. If the x-axis goes from 100 to 200 then
xleft should be larger than 100 and xright should be
less than 200. The position vectors will be recycled to the length of the
longest.
