+ Introduction
|
|
|
|
"gd" is a C graphics library created by Thomas Boutell that allows your
|
|
code to quickly draw complete images with lines, polygons, arcs, text,
|
|
multiple colors, cut and paste from other images, flood fills, read in
|
|
or write out images in the PNG, JPEG or GIF format. This is particularly
|
|
useful in World Wide Web applications, where PNG and JPEG are two of the
|
|
formats accepted for inline images by most browsers. gd does not provide
|
|
for every possible desirable graphics operation. It is not necessary or
|
|
desirable for gd to become a kitchen-sink graphics package, but it does
|
|
include most frequently requested features, including both truecolor
|
|
and palette images, resampling (smooth resizing of truecolor images)
|
|
and so forth. You can get more information about gd from it's homepage.
|
|
|
|
Lua-GD is a "binding": a library that exports gd functions to the Lua
|
|
Programming Language, allowing you to use gd from Lua. The API was
|
|
NOT literally exported, but changed in a way that make it familiar to
|
|
Lua users.
|
|
|
|
Lua-GD is a programming library, not a paint program. If you are looking
|
|
for that or are not familiar to the Lua Programming Language, you are
|
|
in the wrong place.
