SNIPPETS
A snippet is a rectangular area within an image. To specify a snippet, enclose it in parentheses as follows:
( Tn Bn Ln Rn ) where T, B, L, and R are the top, bottom, left, and right borders of the area and n
is the distance of the border from an edge of the image. If n is positive, it represents the distance from the
bottom or right edge; if negative, from the top or left edge. An integer represents pixels, a number
containing a decimal point represents inches, and a number with a comma in place of the decimal point
represents centimeters. There are 200 pixels per inch. These four parameters are all optional and may
occur in any order.
Note
When a snippet is specified, the resulting file will be uncompressed
grayscale with 1, 2, 4, or 8 bits per pixel as given in SWI.
Multiple snippets may appear on the same command line. The commands that may use snippets are: TI,
SI
, and BC. For example:
TI ( T375 B325 L500 R100)
specifies a snippet 51 pixels high by 401 pixels long.
SI ( L2.0) ( R-1,8)
specifies two snippets: (the right-most 2 inches) and (the left-most
1.8 cm).
