Image Buttons for AHK GUIs.

To run the sample script, you have to copy PIC1.jpg and PIC2.jpg included in the \Resources folder into the script folder.

The class creates an image list and assigns it to the pushbutton control. Button image lists may contain one or six images. If they contain only one image, the image will be used to draw all button states (i.e. the button won't be animated). Otherwise the images will be used to draw the appropriate six button states:

PBS_NORMAL    = 1
PBS_HOT       = 2
PBS_PRESSED   = 3
PBS_DISABLED  = 4
PBS_DEFAULTED = 5
PBS_STYLUSHOT = 6 ; used only on tablet computers

1. Create a push button (e.g. Gui, Add, Button, vMyButton HwndHBTN, Caption) using the Hwnd option to get its HWND.

2. Call ImageButton.Create() passing two parameters:

    HWND        -  Button's HWND.  
    Options*    -  variadic array containing up to 6 option arrays (see below).
   

   The index of each option object determines the corresponding button state on which the bitmap will be shown (see above).

   If you don't want the button to be 'animated' on themed GUIs, just pass one option object with index 1.

   Each option array may contain the following values:

      Index Value
      1     Mode        mandatory:
                        0  -  unicolored or bitmap
                        1  -  vertical bicolored
                        2  -  horizontal bicolored
                        3  -  vertical gradient
                        4  -  horizontal gradient
                        5  -  vertical gradient using StartColor at both borders and TargetColor at the center
                        6  -  horizontal gradient using StartColor at both borders and TargetColor at the center
                        7  -  'raised' style
      2     StartColor  mandatory for Option[1], higher indices will inherit the value of Option[1], if omitted:
                        -  ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
                        -  Path of an image file or HBITMAP handle for mode 0.
      3     TargetColor mandatory for Option[1] if Mode > 0. Higher indcices will inherit the color of Option[1],
                        if omitted:
                        -  ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
                        -  String "HICON" if StartColor contains a HICON handle.
      4     TextColor   optional, if omitted, the default text color will be used for Option[1], higher indices
                        will inherit the color of Option[1]:
                        -  ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
                           Default: 0xFF000000 (black)
      5     Rounded     optional:
                        -  Radius of the rounded corners in pixel; the letters 'H' and 'W' may be specified
                           also to use the half of the button's height or width respectively.
                           Default: 0 - not rounded
      6     GuiColor    optional, needed for rounded buttons if you've changed the GUI background color:
                        -  RGB integer value (0xRRGGBB) or HTML color name ("Red").
                           Default: AHK default GUI background color
      7     BorderColor optional, ignored for modes 0 (bitmap) and 7, color of the border:
                        -  RGB integer value (0xRRGGBB) or HTML color name ("Red").
      8     BorderWidth optional, ignored for modes 0 (bitmap) and 7, width of the border in pixels:
                        -  Default: 1
   

   If the the button has a caption it will be drawn above the bitmap.

3. That's all!
