drawFromGIF - Add pictures to your charts

This function allows you to add GIF pictures to your charts. If you turn on shadow support before calling this function, the merged picture will be drawn with the specified shadow parameters.

Calling this function
drawFromGIF($X,$Y,$FileName);
Where :

X,Y are the coordinate where will be drawn the top left corner of the picture.
FileName is the path to the picture file.

It is recommended to use PNG files when you want to include pictures into your charts. This is the only real portable format that can handle alpha channels, thus the pictures will look crystal clear.


Sample script



 /* Turn off shadow */
 $myPicture->setShadow(FALSE);
 $myPicture->drawFromPNG(180,50,"resources/computer.gif");

 /* Enable shadow */
 $myPicture->setShadow(TRUE,array("X"=>2,"Y"=>2,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>20)); 
 $myPicture->drawFromPNG(400,50,"resources/computer.gif");

This will draw two pictures, the first one with only transparency channel included in the GIF file and the second one with the internal pChart shadow algorithm.
