led.image()¶

**led.image -- Simulated LED display image. (V42)

SUPERCLASS
    imageclass

DESCRIPTION
    The led.image image class provides a simulated LED image display.

METHODS
    OM_NEW--Create the LED image.  Passed to superclass, then OM_SET.

    OM_SET--Set object attributes.  Passed to superclass first.

    OM_UPDATE--Set object notification attributes.  Passed to superclass
        first.

    IM_DRAW--Renders the images.  Overrides the superclass.

    All other methods are passed to the superclass, including OM_DISPOSE.

ATTRIBUTES
    SYSIA_DrawInfo (struct DrawInfo *) -- Contains important pen
        information.  This is required if IA_BGPen and IA_FGPen are
        not specified.

    IA_FGPen (LONG) -- Pen to use to draw the lit segments.  If -1
        is specified then TEXTPEN is used.

    IA_BGPen (LONG) -- Pen to use to draw the unlit segments or
        background.  If -1 is specified then BACKGROUNDPEN is used.
        Ignored prior to V47.

    IA_Width (LONG) -- Width of the image.

    IA_Height (LONG) -- Height of the image.

    LED_Pairs (LONG) -- Number of pairs of digits.

    LED_Values (WORD *) -- Array of values.  One entry per pair
        is required.

    LED_Colon (BOOL) -- Is the colon between pairs lit or not.
        Defaults to FALSE.

    LED_Negative (BOOL) -- Is the negative sign lit or not.
        Defaults to FALSE.

    LED_Signed (BOOL) -- Leave room for a negative sign or
        not.  Defaults to FALSE.

    LED_Time (BOOL) -- Leave space for a colon or not. Defaults to
        TRUE. (V47.3)

    LED_Hexadecimal (BOOL) -- Hexadecimal instead of decimal output.
        Defaults to FALSE. (V47.3)

    LED_Raw (BOOL) -- Raw mode; allows arbitrary combinations of segments
        to be lit. In this mode, each byte of the array at LED_Values
        is interpreted as follows (on bits are lit, off bits are unlit):

        bit 7: currently ignored
        bit 6: top
        bit 5: top left
        bit 4: top right
        bit 3: middle
        bit 2: bottom left
        bit 1: bottom right
        bit 0: bottom

        The high byte of each word pertains to the left digit of the
        pair, and the low byte pertains to the right digit.

        Eg. to form a lowercase "ab", a value of $5F2F would be used.
        (V47.3)**
