{{Useful Function}}
<lowercasetitle/>
__NOTOC__
This function draws a 2D blured rectangle on the screen - rendered for one frame. This should be used in conjunction with onClientRender for continuous display.

== Syntax ==
<syntaxhighlight lang="lua">
bool dxDrawBluredRectangle ( float x, float y, float width, float height )
</syntaxhighlight>

=== Required Arguments ===
* '''x:''' An float representing the '''absolute''' origin X position of the rectangle, represented by pixels on the screen.
* '''y:''' An float representing the '''absolute''' origin Y position of the rectangle, represented by pixels on the screen.
* '''width:''' An float representing the width of the rectangle, drawn in a ''right'' direction from the origin.
* '''height:''' An float representing the height of the rectangle, drawn in a ''downwards'' direction from the origin.
