NAME
img-png - Img, Portable Network Graphics format (png)
SYNOPSIS
package require Tk
package require img::png ?1.3?
image create photo ?name? ?options?
DESCRIPTION
The package img::png 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::png.
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 Portable Network Graphics format (png). More specifically img::png extends Tk's photo image type.
The name of the new format handler is png. This handler provides new additional configuration options. See section PNG OPTIONS for more
detailed explanations.
All of the above means that in a call like
image create photo ?name? ?options?
[1] Image data in png format (options -data and -file) is detected automatically.
[2] The format name png 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 PNG OPTIONS.
PNG OPTIONS
The handler provides no true options at all, but accepts pairs of keys and values when writing a PNG file. Each pair will be written as a
named text chunk where the key provides the name of the chunk and the value its contents. For example
png Author <name> Title <title> Description ...
TRANSPARENCY
If you want to write images to disk which contain transparency information (e.g. PNG with alpha channel) you need at least Tk 8.3.
