SYNOPSIS¶
package require

package require
img::tiff ?1.4?

name? ?

DESCRIPTION¶
The package
img::tiff is a sub-package of
Img. It can be loaded as
a part of the complete Img support, via
package require Img, or on its
own, via
package require img::tiff.
Like all packages of
Img it does
not provide new commands, but
extends the existing
Tk command
image so that it supports files
containing raster images in the Tagged Image File Format (tiff). More
specifically
img::tiff extends
Tk's
photo image type.
The name of the new format handler is
tiff. This handler provides new
additional configuration options. See section
TIFF OPTIONS for more
detailed explanations.
All of the above means that in a call like
- image create photo ?name? ?options?
- [1]
- Image data in tiff format (options -data and -file) is
detected automatically.
- [2]
- The format name tiff is recognized by the option -format. In
addition the value for the option is treated as list and may contain any
of the special options listed in section TIFF OPTIONS.
TIFF OPTIONS¶
The handler provides three options, one for reading from a TIFF image, the other
two influencing the writing of such.
- -index n
- This option is for reading from TIFF files containing more than one image
( multi-page TIFF. When specified it will read the n'th
image in the data. The first image is at index 0 and will be read
by default, i.e. when the option is not specified.
- -compression type
- This option specifies the type of compression to use when writing TIFF
data. It has to be one of none, jpeg, packbits, or
deflate. The default is none.
- -byteorder type
- This option specifies the byteorder to use when writing TIFF data. It has
to be one of bigendian, littleendian, network,
smallendian, or the empty string. The default is the empty string.
The values bigendian and network are aliases of each other, as
are littleendian and smallendian.
