img-ppm - Img, Portable Pixmap format (ppm)
package require Tk
package require img::ppm ?1.3?
image create photo ?name? ?options?
The package img::ppm 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::ppm.
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 Pixmap format (ppm). More specifically img::ppm extends Tk's photo image type.
The name of the new format handler is ppm. This handler does not provide additional configuration options.
All of the above means that in a call like
image create photo ?name? ?options?
 Image data in ppm format (options -data and -file) is detected automatically.
 The format name ppm is recognized by the option -format.
SUPPORTED PPM TYPES
There are two types of PPM files: RAW (binary) and ASCII. Currently only the RAW format is implemented.
8-bit pixels: Grayscale, also known as PGM.
24-bit pixels: True-color (RGB, each channel 8 bit).
List of currently supported features:
Type | Read | Write |
| -file | -data | -file | -data |
8-bit | Yes | Yes | Yes | Yes |
24-bit | Yes | Yes | Yes | Yes |

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
