Image::Base::Text -- draw in a plain text file or grid
use Image::Base::Text; my $image = Image::Base::Text->new (-width => 70, -height => 20); $image->rectangle (5,5, 65,15, '*'); $image->save ('/some/filename.txt');
Image::Base::Text is a subclass of Image::Base,
Image::Base::Text
Image::Base
Image::Base Image::Base::Text
Image::Base::Text extends Image::Base to create or update text files treated as grids of characters, or just to create a grid of characters in memory.
Colours for drawing can be a single character to set in the image, or there's an experimental -colour_to_character attribute to map names to characters. Currently black, #000000, #000000000000 and clear all become spaces and anything else becomes a "*". Perhaps that will change.
-colour_to_character
Perl wide characters can be used, in new enough Perl, though currently there's nothing to set input or output encoding for file read/write (making it fairly useless, unless perhaps you've got global PerlIO layers setup).
See "FUNCTIONS" in Image::Base for the behaviour common to all Image-Base classes.
$image = Image::Base::Text->new (key=>value,...)
Create and return an image object. A image can be started with -width and -height,
-width
-height
$image = Image::Base::Text->new (-width => 70, -height => 20);
Or an existing file can be read,
$image = Image::Base::Text->new (-file => '/my/filename.txt');
$new_image = $image->new (key=>value,...)
Create and return a cloned copy of $image. The optional parameters are applied to the new image as per set.
$image
set
$image->load ()
$image->load ($filename)
Read a text file into $image, either from the current -file option, or set that option to $filename and read from there.
-file
$filename
Tab characters in the file are expanded to spaces per Text::Tabs. Its $Text::Tabs::tabstop controls the width of each tab.
Text::Tabs
$Text::Tabs::tabstop
-height is set to the number of lines in the file, possibly zero. -width is set to the widest line in the file and other lines are padded with spaces to that width as necessary.
$image->save ()
$image->save ($filename)
Save the image to a text file, either the current -file option, or set that option to $filename and save to there.
Trailing spaces are included in the output so that the width is represented in the file, and to keep it a rectangular grid. Tabs are not used in the output.
Setting these resizes an image, either truncating or extending. When extending the new area is initialized to space characters.
