In UNIX the dynamic libraries were NOT built with + the -fpic parameter. In MacOS X the dynamic libraries are in bundle format. The source code along with the + "config.mak" files for <b>Tecmake</b> are also available.</p> +<p>The DLLs were built using the <b>cdecl</b> calling convention. This should be +a problem for Visual Basic users.</p> +<p>In Visual C++ we use the single thread C Run Time Library for static libraries and the multi thread C RTL for DLLs. + Because this is the default in Visual Studio for new projects. In Visual C++ 8 both use the multi thread C RTL.</p> +<h3><a name="pack">Packaging</a></h3> +<p>The package files available for download are named according to the platform where they were build.</p> +<p>In UNIX all strings are based in the result of the command "uname -a". The package name is a concatenation of the + platform <b>uname</b>, the system <b>major</b> version number and the system +<b>minor</b> version number. Some times a + suffix must be added to complement the name. The default compiler is gcc, if the native compiler is used the name + receive the suffix "cc". Binaries for 64-bits receive the suffix: "_64". In Linux when gcc is changed for the same + uname in a new platform the major version number of the compiler is added as a suffix: "g3" for gcc 3 and "g4" for gcc + 4.</p> +<p>In Windows the platform name is the <b>compiler</b> and its <b>major</b> version number. +</p> +<p>All library packages contains binaries for the specified platform and includes. Packages with "_bin" suffix + contains executables only.</p> +<p>The package name is a general reference for the platform. If you have the same platform it will work fine, but it + may also work in similar platforms.</p> +<p>Here are some examples of packages:</p> +<p class="info"><b>iup2_4_AIX43_64_bin.tar.gz</b> = IUP 2.4 64-bits Executables for AIX version 4.3<br> +<b>iup2_4_Linux26g4_lib.tar.gz</b> = IUP 2.4 32-bits Libraries and Includes for Linux with Kernel version 2.6 built with + gcc 4.<br> +<b>iup2_4_Win32_vc7_lib.tar.gz</b> = IUP 2.4 32-bits Libraries and Includes for Windows to use with Visual C++ 7.<br> +<b>iup2_4_Docs_html.tar.gz</b> = IUP 2.4 documentation files in HTML format (the web site files can be browsed + locally).<br> +<b>iup2_4_Win32_bin.tar.gz</b> = IUP 2.4 32-bits Executables for Windows.</p> +<p>The documentation files are in HTML format. They do not include the CHM and PDF versions. These two files are + provided only as a separate download, but they all have the same documentation.</p> +<h3><a name="install">Installation</a></h3> +<p>For any platform we recommend you to create a folder to contain the third party libraries you download. Then just + unpack the packages you download in that folder. The packages already contains a directory structure that separates + each library or toolkit. For example:</p> +<pre>\mylibs\ + iup\ + bin\ + html\ + include\ + lib\Linux26 + lib\vc7 + src + cd\ + im\ + lua5\</pre> +<p>This structure will also made the process of building from sources more simple, since the projects and makefiles + will assume this structure .</p> +<h3><a name="usage">Usage</a></h3> +<p>For makefiles use:</p> +<pre>1) "-I/mylibs/iup/include" to find include files +2) "-L/mylibs/iup/lib/Linux26" to find library files +3) "-liup" to specify the library files</pre> +<p>For IDEs the configuration involves the same 3 steps above, but each IDE has a different dialog.

In a GL paradigm you use <strong>primitives</strong>, which have + <strong>attributes</strong>, to draw on a <strong>canvas</strong>. All the library functions reflect this paradigm.</p> + <p>The <strong>canvas</strong> is the basic element. It can have several forms: a paper, a video monitor, a graphic + file format, etc. The virtual drawing surface where the canvas exists is represented by a <strong>driver</strong>. + Only the driver knows how to draw on its surface. The user does not use the driver directly, but only the canvas.</p> + <p>To make the library simple we use the concept of an active canvas, over which all the primitives are drawn. This + also allows the use of an expansion mechanism using function tables. Unfortunately if a function is called without an + active canvas a memory invasion will occur. On the other hand, the mechanism allows the library to be expanded with + new drivers without limits.</p> + <p>The <strong>attributes</strong> are also separated from the primitives. They reside in the canvas in a state + mechanism. If you change the attribute's state in the canvas all the primitives drawn after that canvas and that + depend on the attribute will be drawn in a different way.</p> + <p>The set of <strong>primitives</strong> is very small but complete enough to compose a GL. Some primitives are + system dependent for performance reasons. Some drivers (window and device based) use system functions to optimally + implement the primitives. Sometimes this implies in a in small different behavior of some functions. Also some + primitives do not make sense in some drivers, like server images in file-based drivers.</p> + <p>The set of available functions is such that it can be implemented in most drivers. Some drivers have sophisticated + resources, which cannot be implemented in other drivers but can be made available using a generic attribute mecanism. + </p> + +<h3><a name="buildapp">Building Applications</a></h3> + + <p>All the CD functions are declared in the <tt>cd.h</tt> header file; World Coordinate functions are declared in the + <tt>wd.h</tt> header file; and each driver has a correspondent header file that must be included to create a canvas. + It is important to include each driver header <u>after</u> the inclusion of the <tt>cd.h</tt> header file.</p> + <p>To link the application you must add the <b>cd.lib/libcd.a/libcd.so</b> and <b> + freetype6.lib/libfreetype.a/libfreetype.so </b> libraries to the linker options.

For this reason, we provide + a code of the + simplest driver possible, see <a href="../download/cdxx.h">CDXX.H</a> and <a href="../download/cdxx.c">CDXX.C</a>. + But first you should read the <a href="internal.html">Internal Architecture</a>.</p> + +<h3><a name="Play">Intercepting Primitives</a></h3> + + <p>To fill data structures of library primitives during a <font face="Courier New">cdPlay</font> call you must + implement a driver and activate it before calling <font face="Courier New">cdPlay</font>. Inside your driver + primitives you can fill your data structure with the information interpreted by the <font face="Courier New">cdPlay</font> + function.</p> + +<h3><a name="IUP">IUP Compatibility</a></h3> + + <p>The <strong>IupCanvas</strong> element of the <a target="_blank" href="http://www.tecgraf.puc-rio.br/iup/">IUP</a> + interface toolkit can be used as a visualization surface for a CD canvas. There are two moments in which one must be + careful when an application is using both libraries: when creating the CD canvas, and when changing the size of the + IUP canvas.</p> + <h4>Creating the CD Canvas</h4> + + <p>The CD_IUP driver parameter needs only the Ihandle* of the <strong> + IupCanvas</strong>. But <strong>cdCreateCanvas</strong> must be called <u>after</u> the <strong>IupCanvas</strong> element has been + mapped into the native system.</p> + <p>But a call to <strong>IupShow</strong> generates an ACTION callback. And a + direct call to <strong>IupMap</strong> can generate a RESIZE_CB callback. </p> + <p>So the best way to create a CD canvas for a IUP canvas is to use the + <strong>IupCanvas</strong> MAP_CB callback. This callback will be always called before + any other callback.</p> + + <p>The application must be linked with the <strong>iupcd</strong> + library that it is available in the IUP package.</p> + + <h4>Resizing the IUP Canvas</h4> + + <p>When a IupCanvas is resized the CD canvas must be notified of the size + change. To do that simply call <strong>cdCanvasActivate</strong> in the + RESIZE_CB callback.</p> + + + +</body> + +</html> diff --git a/html/en/history.html b/html/en/history.html new file mode 100644 index 0000000..6042519 --- /dev/null +++ b/html/en/history.html @@ -0,0 +1,932 @@ +<html> + +<head> +<meta http-equiv="content-type" content> +<meta http-equiv="Content-Language" content="en-us"> +<title>History</title> +<link rel="stylesheet" type="text/css" href="../style.css"> +</head> + +<body> + +<h1>History of Changes</h1> +<h3>Version 5.1 (14/Oct/2008)</h3> +<ul> + <li><span style="color: #0000FF">New:</span> CD_DEBUG driver.</li> + <li><span style="color: #0000FF">New:</span> the "imlua_cd" library moved + from IM to CD under the name "cdluaim".

The SIMULATE driver no longer exists, therefore the applications that used it must be modified to use the new +function, <font face="Courier New"><strong>cdSimulate</strong></font>, without the need for creating a new driver.</p> +<ul> + <li>Changed: the internal structure of the library was changed once again. One of the purposes is to make the + drivers become independent from the function table. With this change, adding a new function to the function table does + not imply editing the old drivers. We also allowed the drivers not to implement functions that do not make sense in + their context. Another modification simplifying the work in the drivers was to bring the attribute query mechanism to + the library's control part, freeing the drivers from this obligation. Taking the chance, we determined that a change + in an attribute to a value equal to the current one will not be effective, thus saving calls to the driver. Now, the + value of an attribute is changed even if the driver function is not implemented, as the driver can query this + attribute later on. The management of default values of the attributes is also done by the library's control part. All + these changes prepare the library to a new philosophy: before, if a driver did not contain a certain feature, it + simply did nothing. The new philosophy will be: if a driver does not contain a certain feature, then the simulation of + this feature will be activated.</li> + <li>Changed: when a canvas which is already active is activated again, an internal driver function is now called, + notifying an update instead of an activation.</li> + <li>Changed: the use of the CD canvas with a IUP canvas is better described in the manual, showing the various + ways of treating the canvas creation prooblem.</li> + <li>Changed: all functions in the control module now have <font face="Courier New">ASSERT</font> directives.

Thus, if the <font face="Courier New"><b>cdKillImage</b></font> function is + called with an active canvas of a different kind from that in which the image was created, the + <font face="Courier New"><b>KillImage</b></font> function of the correct driver will be called.</li> + <li>Changed: in the X-Windows driver, the XV code was used to optimize functions <font face="Courier New"><strong> + cdPutImageRectRGB</strong></font> and <font face="Courier New"><strong>cdPutImageRectMap</strong></font>.</li> + <li>Changed: the Lua binding was updated.

The + <font face="Courier New"><strong>cdFlush</strong></font> function was not preserving the canvas attributes.

Such + modules are totally independent from the implemented drivers, as well as every driver + independs from one another, unless there is an intentional dependency.</p> + + +<h3>Linking</h3> + + + <p>Since the drivers independ from one another, we could create a library for each of + them. For the drivers provided with CD it was easy to include them in their own library, + thus simplifying the application's linking process. Note: Internally, the drivers are + called "context".</p> + <p>In order to establish this dependency, when creating a canvas in a given driver the + user must specify the driver to be used. This specification is done by means of a macro + which is actually a function with no parameter, which passes the function table from that + driver to the canvas creation function. For instance:</p> + + <pre><b>CD_PS</b> <em>(is in fact)</em> cdContextPS() +cdCreateCanvas(<b>CD_PS</b>, "teste.ps"); <em>(will do)</em> canvas-><b>Line</b> = context-><b>Line</b></pre> +<p>If the context function is not invoqued then that driver does not need to be +linked with the application.
