PostScript::Graph::Bar Perl module can draw a bar chart on a postscript file.

SYNOPSIS

Simplest

Take labels and values from a csv file and output as a bar chart on a postscript file.

use PostScript::Graph::Bar;

my $bar = new PostScript::Graph::Bar();
$bar->build_chart("survey.csv");
$bar->output("survey");

Typical

use PostScript::Graph::Bar;

my $bar = new PostScript::Graph::Bar(
file => {
paper => A4,
landscape => 1,
},
layout => {
background => [1, 1, 0.9],
heading => Test results,
},
y_axis => {
smallest => 4,
},
style => {
auto => [qw(green blue red)],
}
);

$bar->series_from_file( data.csv );
$bar->build_chart();
$bar->output( results );

The file data.csv has a row of headings followed by 4 rows of 10 items. This produces a bar chart with four groups of ten bars each. The groups are labelled with the first value in each row. The bars in each group are coloured ranging from brown through green and then shades of blue. A Key links the row of headings to each colour. In addition, the background is beige, a heading is placed above the chart and the y axis is not too crowded.

All options

use PostScript::Graph::Bar;

my $bar = new PostScript::Graph::Bar(
file => {
# Paper size, orientation etc
# See PostScript::File
},
layout => {
# General proportions, headings
# See PostScript::Graph::Paper
},
x_axis => {
# All settings for X axis
# See PostScript::Graph::Paper
},
y_axis => {
# All settings for Y axis
# See PostScript::Graph::Paper
},
style => {
# Appearance of bars
# See PostScript::Graph::Style
},
key => {
# Settings for any Key area
# See PostScript::Graph::Key
},
show_key => 1,
labels_row => 1,
);

PostScript::MailLabels are modules for creating PostScript files of mailing address labels.
Flexible enough to tackle other printing tasks, basically anything requiring a set fields be printed on a regular grid. Also creates PostScript(tm) code for calibrating and testing mailing label printing.
The module has three distinct output modes. In my experience, printing mailing labels is a matter of tweaking parameters to get them all to fit properly on the page. This module is designed with this in mind.
The first output is the calibration sheet. This is a pair of annotated axes, either in inches or centimeters, centered on the page and covering the whole page in X and Y directions. The intent is for you to output this page first, and simply read off the relevant page dimensions directly.
The second output is the label test. This output is a series of boxes drawn on the page, meant to outline the edges of all the mailing labels. Take this sheet and line it up with a sheet of labels to see if they actually match perfectly. If not, tweak the parameters until they do. Note that sometimes you will get a message at the bottom of the sheet saying ``Bottom gap too large, last row cannot be printed.
This means that the printable area of your printer is too small to utilize the last row of labels. I have this problem. But I handle it for you. Note also the arrows on the test sheet. As you hold the test sheet over a sheet of labels, hold it up to the light and slide the test sheet so that the boxes match the edges of the labels. If you slide in the arrow direction, that is a positive adjustment.
The other direction is negative. If the edges of some boxes come out dashed, that means that the non-printing border cuts off the end of the label, so I will adjust the printing area appropriately. Dont try to line up the dashed lines with label edges - it wont work. Just line up the solid lines.
The third output is the labels themselves. By default, I have set up a US-centric address definition :
firstname, lastname, street address, city, state, zipcode
But with version 2.0, you can now create your own definition. You can define new fields, and you can define how those fields land on a label. You can also control the fonts on a per-field basis. Not the size, yet - later pilgrim.
Parameters you can set :
Paper size, orientation, borders on the printable area (many printers will not print right up to the edge of the paper), where the labels live on the page and how big they are, overall x-y shift of page, whether or not to print PostNET barcode, font, fontsize, units (english or metric), which Avery(tm) product code to use, and where the first label starts.
This last needs explanation. If you have a partially used sheet of labels, you might want to use it up. So you count the missing labels, starting at the upper left, and counting across, and then down. For example, if I have 3 columns of labels, label five is the second label in the second row.
If you have an Avery(tm) product that I havent defined, send me the specs and Ill add it.
Also, if there is another brand of labels that you use, send me the relevant data and Ill add that as well. I suspect that there must be some other vendor in Europe, but I dont know who that would be.
When setting up the addresses, I check to see if they will fit on the label. If not, I try to shorten them semi-intelligently until they fit. This part could use quite a bit more work, if done right it probably merits a module all its own.
Briefly, for the name line, I start trimming the ends off the first name, and leave the last name alone.
For the street, I look for things like Road or Avenue and nuke those first, then I trim the street name from the right.
Enhancements:
- Parentheses are now escaped in the generated PostScript code.

GNU Barcode is a tool to convert text strings to printed bars. GNU barcode supports a variety of standard codes to represent the textual strings and creates postscript output.
Main features:
- Available as both a library and an executable program
- Supports UPC, EAN, ISBN, CODE39 and other encoding standards
- Postscript and Encapsulated Postscript output
- Accepts sizes and positions as inches, centimeters, millimeters
- Can create tables of barcodes (to print labels on sticker pages)

phpCDLabelPS creates labels for your data/MP3 CDs using PHP and PostScript (output will be a postscript file). It is controled by a frontend and a PostScript template.

To install, just extract all files somewhere in your webtree. Then point your browser to cdlabel.php - thats it. You may want to check the config.inc file and change the default values to your own preferences at any time: it just sets up the initial form values. One thing you may want to adjust right in the beginning is the mount-point of your media.

Plotting all 2D and 3D functions had never been so easy. Many samples are included.
Its also possible to print or export the plots in postscript format.
Main features:
- Plot any 2D or 3D parametric function
- Save and open parameters of a plot
- Print or export to postscript format
- Separate output and control windows to allow more working space
- Many samples included
- Zoom and axis control

PyScript project is a python module for producing high quality postscript graphics. Rather than use a GUI to draw a picture, the picture is programmed using python and the PyScript objects.
Main features:
- All scripting is done in python, which is a high level, easy to learn, well-developed scripting language.
- All the objects can be translated, scaled, rotated, ... in fact any affine transformation.
- Plain text is automatically kerned.
- You can place arbitrary LaTeX expressions on your figures.
- You can create your own figure objects, and develop a library of figure primitives.
- Output is publication quality.

AutoTrace is a program for converting bitmap to vector graphics. The aim of the AutoTrace project is the development of a freely available application with a functionality similar to CorelTrace or Adobe Streamline.
Main features:
- Inputformats BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick.
- Exportformat Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk
