NAME
img-ps - Img, Adobe PostScript Format (ps) SYNOPSIS
package require Tk package require img::ps ?1.4? image create photo ?name? ?options? _________________________________________________________________ DESCRIPTION
The package img::ps 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::ps. 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 Adobe PostScript Format (ps). More specifically img::ps extends Tk's photo image type. The name of the new format handler is ps. This handler provides new additional configuration options. See section PostScript OPTIONS for more detailed explanations. Note that this package provides a pdf handler too, i.e. a handler for the Adobe Portable Document Format. That handler accepts the same options as the ps handler. The package delegates the actual conversion of data in PostScript and PDF format into a raster image to the ghostscript application. It therefore depends upon the presence of said application and is non-functional is ghostscript is not present. All of the above means that in a call like image create photo ?name? ?options? [1] Image data in ps and PDF format (options -data and -file) is detected automatically. [2] The format names ps and pdf are 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 PostScript OPTIONS. POSTSCRIPT OPTIONS
The handler provides two options, both influencing the reading of PostScript or PDF images. The handler is not able to write images in PostScript or PDF. -index n This option is for reading from PostScript/PDF data containing more than one page. When specified it will read the n'th page in the data. The first page is at index 0 and will be read by default, i.e. when the option is not specified. Note: This option is not yet implemented. -zoom X Y Multiply image size by the given scale factors. If Y is missing, the default is the same as X. X and Y are allowed to be in floating point format, but they are rounded to the nearest practically possible value. For postscript this means the zoom factors should be multiples of 1/72. REQUIREMENTS
The code provided by Img does not perform the interpretation and rasterizing of the input by itself but delegates this to the gs applica- tion. This is the GhostScript implementation of PostScript (and PDF). If gs is not installed this format handler cannot be used. SEE ALSO

NAME
img-tiff - Img, Tagged Image File Format (tiff) SYNOPSIS
package require Tk package require img::tiff ?1.4? image create photo ?name? ?options? _________________________________________________________________ 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, smallen- dian, 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. SEE ALSO
