- * Use MPlayer as a framebuffer to read bitmaps and commands from a FIFO
- * and display them in the window.
- *
- * Commands are:
- *
- * RGBA32 width height xpos ypos alpha clear
- * * Followed by width*height*4 bytes of raw RGBA32 data.
- * ABGR32 width height xpos ypos alpha clear
- * * Followed by width*height*4 bytes of raw ABGR32 data.
- * RGB24 width height xpos ypos alpha clear
- * * Followed by width*height*3 bytes of raw RGB32 data.
- * BGR24 width height xpos ypos alpha clear
- * * Followed by width*height*3 bytes of raw BGR32 data.
- *
- * ALPHA width height xpos ypos alpha
- * * Change alpha for area
- * CLEAR width height xpos ypos
- * * Clear area
- * OPAQUE
- * * Disable all alpha transparency!
- * Send "ALPHA 0 0 0 0 0" to enable again!
- * HIDE
- * * Hide bitmap
- * SHOW
- * * Show bitmap
- *
- * Arguments are:
- * width, height Size of image/area
- * xpos, ypos Start blitting at X/Y position
- * alpha Set alpha difference. 0 means same as original.
- * 255 makes everything opaque
- * -255 makes everything transparent
- * If you set this to -255 you can then send a sequence of
- * ALPHA-commands to set the area to -225, -200, -175 etc
- * for a nice fade-in-effect! ;)
- * clear Clear the framebuffer before blitting. 1 means clear.
- * If 0, the image will just be blitted on top of the old
- * one, so you don't need to send 1,8MB of RGBA32 data
- * everytime a small part of the screen is updated.
- *
- * Arguments for the filter are hidden:opaque:fifo
- * For example 1:0:/tmp/myfifo.fifo will start the filter hidden, transparent
- * and use /tmp/myfifo.fifo as the fifo.
- *
- * If you find bugs, please send me patches! ;)
- *
- * This filter was developed for use in Freevo (http://freevo.sf.net), but
- * anyone is free to use it! ;)
