a2Option_FlipY() This returns a value used by the "options" parameter of the a2DrawImage command.
Syntax
    a2Option_FlipY()
Parameters
This function has no parameters.
Returns
This function returns a value of 2.
Description
This function is used by the "options" parameter of the Advanced 2D a2DrawImage command to indicate that the image is to be drawn vertically flipped. The original image is not changed. Note that when the image is drawn vertically flipped, the local y origin is changed by the height of the image, but can be reassigned with the centerY parameter of the a2DrawImage command.
Example Code
    cls 0xFFFFFFFF
    a2FillBox 2,2,62,62,0xFFFF0000
    font1 = a2CreateFont("ariel", 78, a2Size_Char(), a2Style_Normal())
    a2Text font1, 2, -10, "R", 0xFFFFFFFF
    get image 1,0,0,64,64,1
    cls 0

    rem Draw the unflipped image
    a2DrawImage 1,150,100,0,0,0,1,0,0xFFFFFFFF

    rem Draw the horizontally flipped image, offset by image width
    a2DrawImage 1,150,200,0,64,0,1,a2Option_FlipX(),0xFFFFFFFF

    rem Draw the vertically flipped image, offset by image height
    a2DrawImage 1,250,100,0,0,64,1,a2Option_FlipY(),0xFFFFFFFF
