Examples
--------

To plot the remote image needle.jpg, scaling it be 7 cm wide (height is scaled
accordingly), use::

    gmt psimage @needle.jpg -Dx0/0+w7c > image.ps

To plot the same file but reversing the bands, use::

    gmt psimage @needle.jpg+b2,1,0 -Dx0/0+w7c > image.ps

To only plot its red band as gray shade, use::

    gmt psimage @needle.jpg+b0 -Dx0/0+w7c > image.ps

To include an Encapsulated PostScript file gallo.eps with its upper
right corner 2 inch to the right and 1 inch up from the current
location, and have its width scaled to 3 inches, while keeping the
aspect ratio, use::

    gmt psimage @gallo.eps -Dx2i/1i+jTR+w3i > image.ps

To replicate the 1-bit remote raster image vader1.png, colorize it
(dark gray background and yellow foreground), and setting each of 6 by 12 tiles
to be 2.5 cm wide, use::

    gmt psimage @vader1.png -Gdarkgray+b -Gyellow+f -Dx0/0+w2.5c+n6/12 -P > image.ps
