\page Image_Control Image Control
\brief **Used to show an image.**
\tableofcontents
The image control is used for displaying images in Kodi. You can choose the
position, size, transparency and contents of the image to be displayed.
--------------------------------------------------------------------------------
\section Image_Control_sect1 Example
~~~~~~~~~~~~~
<control type="image" id="1">
<description>My first image control</description>
<posx>80</posx>
<posy>60</posy>
<width>250</width>
<height>200</height>
<visible>true</visible>
<colordiffuse>FFFFFFFF</colordiffuse>
<fadetime>200</fadetime>
<texture border="5" flipy="true" flipx="false">mytexture.png</texture>
<bordertexture border="5">mybordertexture.png</bordertexture>
<bordersize>5</bordersize>
<texture>$INFO[MusicPlayer.Cover]</texture>
<aspectratio>keep</aspectratio>
</control>
~~~~~~~~~~~~~
--------------------------------------------------------------------------------
\section Image_Control_sect2 Image Size and Type Restrictions
For the <b>`<texture>`</b> tags, and for all <b>`<texture>`</b> tags in
other controls, there is a small set of rules that you should follow if at all
possible:
\subsection Image_Control_sect2_1 Size
Images can be any size, though some graphics cards allow only power of 2 textures,
so this may be a consideration. For the most case, it doesn't really matter what
size things are - Kodi will quite happily load most files.
\subsection Image_Control_sect2_2 Formats
If you wish to use transparency, then use PNG. It is suggested that you use PNG
and JPG as much as possible. Note that once the images are injected into
Textures.xbt, they are not stored as JPG or PNG – rather they are stored in
a native format used for GPUs for faster loading, such as ARGB or DXTc textures.
The size of the images (in kb) is therefore not as important as the size of the
images in pixels – so feel free to store them in a lossless (eg PNG) manner if
you wish.
The only exception to this is if you require an animated texture. In this case,
we support only animated GIF. There are also some animated gifs that may not
work. Use ImageReady CS and make sure you set the gif-anim to “restore to
background” and they should work fine.
--------------------------------------------------------------------------------
\section Image_Control_sect3 Available tags and attributes
In addition to the [Default Control Tags](http://kodi.wiki/view/Default_Control_Tags)
the following tags are available. Note that each tag is **lower case** only. This is
important, as `xml` tags are case-sensitive.
| Tag | Description |
|--------------:|:--------------------------------------------------------------|
| aspectratio | This specifies how the image will be drawn inside the box defined by <b>`<width>`</b> and <b>`<height>`</b>. [See here for more information](http://kodi.wiki/view/Aspect_Ratio).
| texture | Specifies the image file which should be displayed. [See here for additional information about textures](http://kodi.wiki/view/Texture_Attributes).
| bordertexture | Specifies the image file which should be displayed as a border around the image. Use the <b>`<bordersize>`</b> to specify the size of the border. The <b>`<width>`</b>, <b>`<height>`</b> box specifies the size of the image plus border.
| bordersize | Specifies the size of the border. A single number specifies the border should be the same size all the way around the image, whereas a comma separated list of 4 values indicates left,top,right,bottom values.
| info | Specifies the information that this image control is presenting. Kodi will select the texture to use based on this tag. [See here for more information](http://kodi.wiki/view/InfoLabels).
| fadetime | This specifies a crossfade time that will be used whenever the underlying <b>`<texture>`</b> filename changes. The previous image will be held until the new image is ready, and then they will be crossfaded. This is particularly useful for a large thumbnail image showing the focused item in a list, or for fanart or other large backdrops.
| background | For images inside a container, you can specify background="true" to load the textures in a background worker thread. [See here for additional information about background loading](http://kodi.wiki/view/Background_Image_Loader).
For the tags "texture" and "bordertexture", the following attributes are available.
| Attribute | Description |
|--------------:|:--------------------------------------------------------------|
| border | Used to specify a region of the texture to be considered a border that should not be scaled when the texture is scaled to fit a control's dimensions. The portion in the border region will remain unscaled. Particularly useful to achieve rounded corners that do not change size when a control is resized. Note that zoom animations and GUI rescaling will still affect the border region - it is just the scaling of the texture to the control size which is unaffected. Using border="5" will give a 5 pixel border all around the texture. You can specify each of the border amounts on each edge individually using border="left,top,right,bottom".
| infill | Available if the "border" attribute is used. Hint for the GUI drawing routine if the center portion or just the outer frame should be drawn. Useful if the texture center is fully transparent. Accepts boolean values "true" (default) and "false".
| flipx | Specifies that the texture should be flipped in the horizontal direction, useful for reflections.
| flipy | Specifies that the texture should be flipped in the vertical direction, useful for reflections.
| background | Used on the <b>`<imagepath>`</b> tag. When set to "true", this forces the image to be loaded via the large texture manager (except for textures located in Textures.xbt).
| diffuse | Specifies a diffuse texture which is "modulated" or multiplied with the texture in order to give specific effects, such as making the image gain transparency, or tint it in various ways. As it's applied per-pixel many effects are possible, the most popular being by a transparent reflection which slowly gets more and more opaque. This is achieved using a WHITE image where the transparency increases as you move down the texture.
| colordiffuse | This specifies the color to be used for the texture basis. It's is specified in hexadecimal notation using the AARRGGBB format. If you define <b>`<texture colordiffuse="FFFFAAFF">texture.png</texture>`</b> (magenta), the image will be given a magenta tint when rendered. You can also specify this as a name from the colour theme, or you can also use $VAR and $INFO for dynamic values.
@skinning_v20 <b>infill</b> New texture attribute added.
