-<title>Bezier curves</title>
-
-<para>One cool thing with VLC sliders is that they are not necessarily rectilinear, but they can follow any Bezier curve. So if you want to have a slider moving on a half-circle, or even doing a loop, you can!</para>
-
-<para>This is not the place to explain how Bezier curves work (see <ulink url="http://astronomy.swin.edu.au/~pbourke/curves/bezier/">http://astronomy.swin.edu.au/~pbourke/curves/bezier/</ulink> for a nice introduction), the main thing to know is that a Bezier curve can be characterized by a set of points. Once you have them (thanks to the <link linkend="CurveMaker">CurveMaker</link> utility for example<!--XXX: deprecated-->), you just need to enter the list of points in the <link linkend="sliderpoints">points</link> attribute. Here is an example with 3 points: points="(2,50),(45,120),(88,50)".</para>
-
-<para>Bezier curves can be used with the <link linkend="Slider">Slider</link> and <link linkend="Anchor">Anchor</link> tags:</para>
-
-<itemizedlist>
- <listitem><para>For sliders, it defines the curve followed by the cursor of the slider. This curve is of course invisible, so if you want a visible background for your <link linkend="Slider">Slider</link> you need to provide it yourself using the <link linkend="Image">Image</link> tag.</para></listitem>
- <listitem><para>For anchors, the use of Bezier curves is more anecdotic. Its purpose is to have non-ponctual anchor, the whole curve becoming the anchor. In this case, a ponctual anchor (and only a ponctual one) can be attracted by any point of the curve, if it is in its range of action. In fact, you can consider the curve as an easy way to define at once many anchors that share the same properties (except their position, of course :)).</para></listitem>
-</itemizedlist>
-
-<note><para>The coordinates are relative to the upper-left corner of the control (i.e. to its <link linkend="x">x</link> and <link linkend="y">y</link> attributes).</para></note>

<title>The bitmaps</title>
-<para>Basically, you need one bitmap file (in PNG format) by state of control. For example, with a <link linkend="Image">Image</link> control you need 1 image, with a <link linkend="Button">Button</link> control you need 3 images (for the up, down and mouseover states). Of course, the same bitmap file can be used for many controls, provided you want to display the same image!</para>

The same bitmap file can be used for many controls, using <link linkend="SubBitmap">sub-bitmaps</link>.</para>
<para>The PNG format allows setting a transparency mask, which will be used wherever the image needs to be displayed (only non-transparent parts will be drawn). In addition, you can also specify a transparency color in the XML file: the bitmap will be considered as transparent wherever this color appears in the bitmap file.</para>
<note><para>Both the transparency mask and the transparent color will be taken into acount, so if the transparency mask is correctly set in the bitmap file you need to choose a unused color for the transparency color.</para></note>
+<note><para>Starting from VLC 0.8.5, it is not anymore necessary to use PNG format for the bitmap files: most common formats are supported. Using PNG format is still recommended, for compatibility with older VLC versions.</para></note>

<para>XML is a markup language, like HTML. It won't be explained here any further, please use Google if you don't know what XML is. You'll see, it is rather easy to understand.</para>
-<para>The XML file used for the VLC skins follows a predefined DTD. You can find this DTD in VLC CVS, and its reading is strongly advised, since it contains the default values used for the parameters. A skin that does not follow the DTD with which VLC was compiled won't be loaded by VLC (and it might even crash it...).</para>

+<title>Layout model</title>
+
+<para>Placing the controls on a window is easy, using their x and y attributes, but these positions become insufficient for a resizable window. Some controls (or groups of controls) should stay centered in the window, others should follow the right side of the window, others should change their size automatically, etc... To handle these various behaviours, the layout model followed by the skins engine is a model based on nested boxes.</para>
+
+<para>There are 2 kinds of boxes:</para>
+
+<itemizedlist>
+ <listitem><para>
+ <emphasis>simple boxes</emphasis>: These boxes cannot contain other boxes. All the visible controls are simple boxes: Image, Button, Checkbox, Text, Slider, RadialSlider, Playlist, Playtree, Video.
+ </para></listitem>
+ <listitem><para>
+ <emphasis>container boxes</emphasis>: These boxes can contain other boxes. Only two XML tags create container boxes: <link linkend="Panel">Panel</link> and <link linkend="Layout">Layout</link>. The Layout tag is necessarily the top-level box for the current layout, and cannot be contained, but Panel elements can be contained.
+ </para></listitem>
+</itemizedlist>
+
+<para>A box inside a container box always defines how it should react when its container box is resized. Two different mechanisms are provided: corners anchoring (useful when resizing of the inner box is wanted, for example) and constant ratio (mainly useful to keep the inner box centered inside its parent):</para>
+<itemizedlist>
+ <listitem><para>
+ <emphasis>corners anchoring</emphasis>: The top-left-hand corner (TL) and the bottom-right-hand corner (BR) of the inner box are "tied" to corners of the container box (TL, TR, BL or BR). When any resizing occurs, tied corners move together, which can move or resize the inner box. For example, if the TL corner of the inner box is tied to the TL corner of the container (let's write it TL/TL), and if the BR corner of the inner box is also tied to the TL corner of the container box (BR/TL), the inner box will not be resized, and will always stay at the same place (this is the default behaviour). If we have TL/TL and BR/BL, the inner box is resized vertically when its container is resized. If we have TL/TR and BR/TR, the inner box moves with the TR corner of its container. We could even define TL/BR and BR/TL, in which case increasing the size of the container box would shrink the size of the inner box... until it disappears completely!
+ </para>
+ <para>This mechanism is controlled by the <link linkend="lefttop">lefttop</link> and <link linkend="rightbottom">rightbottom</link> attributes of the controls.
+ </para></listitem>
+ <listitem><para>
+ <emphasis>constant ratio</emphasis>: When a box doesn't fill completely its container box, there is space on the top, bottom, left and right of the inner box. It is possible to force the ratio between the space on the top and the space on the bottom (or the one on the left and the one on the right) to be constant. Any resizing of the container box will then move the inner box accordingly, and the size of the inner box will never change (it overrides the corners anchoring mechanism). The horizontal and vertical ratios being independent, it is for example possible to keep only the horizontal ratio constant, in which case the inner box can still resize vertically (depending on its attributes for the corners anchoring, of course).

+<title>Bezier curves</title>
+
+<para>One cool thing with VLC sliders is that they are not necessarily rectilinear, but they can follow any Bezier curve. So if you want to have a slider moving on a half-circle, or even doing a loop, you can!</para>
+
+<para>This is not the place to explain how Bezier curves work (see <ulink url="http://astronomy.swin.edu.au/~pbourke/curves/bezier/">http://astronomy.swin.edu.au/~pbourke/curves/bezier/</ulink> for a nice introduction), the main thing to know is that a Bezier curve can be characterized by a set of points. Once you have them (thanks to the <link linkend="CurveMaker">CurveMaker</link> utility for example<!--XXX: deprecated-->), you just need to enter the list of points in the <link linkend="sliderpoints">points</link> attribute. Here is an example with 3 points: points="(2,50),(45,120),(88,50)".</para>

+ <listitem><para>For anchors, the use of Bezier curves is more anecdotic. Its purpose is to have non-ponctual anchor, the whole curve becoming the anchor. In this case, a ponctual anchor (and only a ponctual one) can be attracted by any point of the curve, if it is in its range of action. In fact, you can consider the curve as an easy way to define at once many anchors that share the same properties (except their position, of course :)).</para></listitem>

<title>Generating Bezier curves</title>
<para>
-To generate easily Bezier curves, you can use the <ulink url="/vlc/skins/VLC-curve-maker.exe">curve-maker</ulink> (sorry, this is for Windows users only). Basically, you add and remove points at will, and you can move them to see how the curve evolves. When you have reached the perfect curve, you just have to copy-paste the list of abscissas and ordinates to form the <link linkend="sliderpoints">points</link> attribute of your <link linkend="Slider">Slider</link> or <link linkend="Playlist">Playlist</link>. The curve-maker also allows to load a .bmp file, this could be useful if you want to follow a specific pattern of a slider, for example.
