View list of data type meanings


Draws a gradient - that is a rectangle that gradually changes from the start colour to the end colour.

Note that changes to miniwindows will not become visible until the output window is redrawn. This happens when new (visible) lines arrive from the MUD, or if you call WindowShow, or Redraw.


WindowName - the name of an existing miniwindow.

Left, Top, Right, Bottom - describes the rectangle to draw into.

StartColour - the colour to start the gradient (or, see below if you are using Mode 3)

EndColour - the colour to end the gradient.

Mode - the drawing direction. One of:

1 - horizontal - left to right

2 - vertical - top to bottom

3 - make a texture by xoring the x and y columns sequentially.

For Mode 3 (make a texture) - the StartColour has 3 components, red multiplier, green multiplier, blue multiplier. These are multiplied by the generated colour to give special effects to the generated texture. For example: 0x010203 would multiply the blue component by 1, the green component by 2 and the red component by 3.
