DxDrawImageSection: Difference between revisions

Revision as of 09:03, 6 October 2012

Differing from dxDrawImage, this function only draws a part of an image on the screen for a single frame. In order for the image to stay visible continuously, you need to call this function with the same parameters on each frame update (see onClientRender).

Syntax

bool dxDrawImageSection ( float posX, float posY, float width, float height, float u, float v, float usize, float vsize, mixed image, 
[ float rotation = 0, float rotationCenterOffsetX = 0, float rotationCenterOffsetY = 0, int color = white, bool postGUI = false ] )

Required Arguments

posX: the absolute X coordinate of the top left corner of the image
posY: the absolute Y coordinate of the top left corner of the image
width: the absolute width of the image
height: the absolute height of the image
u: the absolute X coordinate of the top left corner of the section which should be drawn from image
v: the absolute Y coordinate of the top left corner of the section which should be drawn from image
usize: the absolute width of the image section
vsize: the absolute height of the image section
image: Either a material element or a filepath of the image which is going to be drawn. (.dds images are also supported). Image files should ideally have dimensions that are a power of two, to prevent possible blurring.

Optional Arguments

rotation: the rotation, in degrees for the image.
rotationCenterOffsetX: the absolute X offset from the image center for which to rotate the image from.
rotationCenterOffsetY: the absolute Y offset from the image center for which to rotate the image from.
color: the color of the image, a value produced by tocolor or hexadecimal number in format: 0xAARRGGBB (AA = alpha, RR = red, GG = green, BB = blue).
postgui : A bool representing whether the image should be drawn on top of or behind any ingame GUI (rendered by CEGUI).

Returns

Returns true if successful, false otherwise.
