[Note: I did not strive for a literal translation, but rather one that sounds more like native English structure, grammar, and usage. Unfortunately, it is hard to write technical documentation when I don't even know how GD works myself.] ------------------------------------------------------------------------------------ <html lang="en"> <head> <title>Caché: a plug-in environment for GD dynamic graphics</title> <meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=windows-1252" /> <base href="http://karataev.nm.ru/"; /> <!-- translated from Russian using http://www.free-translator.com/translator5.html --> <style type="text/css"> dt { font-size: small; font-family: monospace; text-indent: -10em; margin-left: 10em; } dd { font-size: small; font-family: sans-serif; text-indent: 0em; margin-left: 20em; } </style> </head> <body> <table width="740" align="center"> <tr><td align="center"> <hr size="1" /> <b>| <a href="/index.html">Main</a> | Mathematics | Programming | Caché | Creativity | Calculators |</b> <hr size="1" /> </td></tr> </table> <table border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td valign="top"> <h1 align="center">Caché: a plug-in-environment for GD</h1> <h2 align="center">graphics on-the-fly</h2> <h3>Installation:</h3> <p align="justify"> Files cos_gd.so (.dll) need to be saved into a bin directory where Caché is.
