ASSOCIATED OPTIONS

WIDGET-SPECIFIC OPTIONS

Name:                   filename
Class:                  FileName
Command-Line Switch:	-filename

The file to write the postscript output to (Only when output is set to "file"). If posterizing is turned on and hpagecnt and/or vpagecnt is more than 1, x.y is appended to the filename where x is the horizontal page number and y the vertical page number.

Name:                   hpagecnt
Class:                  PageCnt
Command-Line Switch:	-hpagecnt

Is used in combination with posterize to determine over how many pages the output should be distributed. This attribute specifies how many pages should be used horizontaly. Any change to this attribute will automatically update the "stamp". Defaults to 1.

Name:                   orient
Class:                  Orient
Command-Line Switch:	-orient

Determines the orientation of the output to the printer (or file). It can take the value "portrait" or "landscape" (default). Changes to this attribute will be reflected immediately in the "stamp". Defaults to "landscape" but will be changed automaticaly to the value deemed appropiate for the current canvas. Setting this attribute when the canvasprintbox is first constructed (instead of using the "configure" method) will turn off the auto adjustment of this attribute.

Name:                   output
Class:                  Output
Command-Line Switch:	-output

Specifies where the postscript output should go: to the printer or to a file. Can take on the values "printer" or "file". The corresponding entry-widget will reflect the contents of either the printcmd attribute or the filename attribute. Defaults to "printer".

Name:                   pageSize
Class:                  PageSize
Command-Line Switch:	-pagesize

The pagesize the printer supports. Changes to this attribute will be reflected immediately in the "stamp". Defaults to "a4".

Name:                   posterize
Class:                  Posterize
Command-Line Switch:	-posterize

Indicates if posterizing is turned on or not. Posterizing the output means that it is possible to distribute the output over more than one page. This way it is possible to print a canvas/region which is larger than the specified pagesize without stretching. If used in combination with stretching it can be used to "blow up" the contents of a canvas to as large as size as you want (See attributes: hpagecnt and vpagecnt). Any change to this attribute will automatically update the "stamp". Defaults to 0.

Name:                   printCmd
Class:                  PrintCmd
Command-Line Switch:	-printcmd

The command to execute when printing the postscript output. The command will get the postscript directed to its standard input (Only when output is set to "printer"). Defaults to "lpr".

Name:                   printRegion
Class:                  PrintRegion
Command-Line Switch:	-printregion

A list of four coordinates specifying which part of the canvas to print. An empty list means that the canvas' entire scrollregion should be printed. Any change to this attribute will automatically update the "stamp". Defaults to an empty list.

Name:                   stretch
Class:                  Stretch
Command-Line Switch:	-stretch

Determines if the output should be stretched to fill the page (as defined by the attribute pagesize) as large as possible. The aspect-ratio of the output will be retained and the output will never fall outside of the boundaries of the page. Defaults to 0 but will be changed automaticaly to the value deemed appropiate for the current canvas. Setting this attribute when the canvasprintbox is first constructed (instead of using the "configure" method) will turn off the auto adjustment of this attribute.

Name:                   vPageCnt
Class:                  PageCnt
Command-Line Switch:	-vpagecnt

Is used in combination with "posterize" to determine over how many pages the output should be distributed. This attribute specifies how many pages should be used verticaly. Any change to this attribute will automatically update the "stamp". Defaults to 1.

DESCRIPTION

Implements a print box for printing the contents of a canvas widget to a printer or a file. It is possible to specify page orientation, the number of pages to print the image on and if the output should be stretched to fit the page. Options exist to control the appearance and actions of the widget.

METHODS

The canvasprintbox command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form:

pathName option ?arg arg ...?
