>>>Warning: This feature requires pixel shader model 2_a<<<

This function creates a quadrilateral shader that can be used for dgs elements.

Syntax

element dgsCreateQuad( table corners [, int color = 0xFFFFFFFF, texture background = nil, bool colorOverwritten = true ] )
Example Rounded Rectangle

Required Arguments

  • corners : A table of the corners of the quadrilateral. The structure is as follows:
{
	{ float LeftTopX, float LeftTopY, bool relative },
	{ float RightTopX, float RightTopY, bool relative },
	{ float RightBottomX, float RightBottomY, bool relative },
	{ float LeftBottomX, float LeftBottomY, bool relative },
}

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • color: An int of the color of the quadrilateral.
  • background: A texture element of the background of the quadrilateral.
  • colorOverwritten: A bool indicates whether the final color will be overwritten by color or the product of render color and color (resultColor = render color * color) when rendering.

Returns

Returns a dgs-dxquad element (dgs Type)/ shader (element Type) if succeed, false otherwise

Example

DGS = exports.dgs --get exported functions from dgs

local rndRect = DGS:dgsCreateRoundRect(50,false,tocolor(0,0,0,150))  --Create Rounded Rectangle with 50 pixels radius 
local image1 = DGS:dgsCreateImage(200,200,400,100,rndRect,false)  --Apply it to the dgs image

Syntax

element dgsCreateRoundRect( table multiArguments [, int color = 0xFFFFFFFF, texture background = nil, bool colorOverwritten = true, bool/int border = false, float borderHorizontalThickness, float borderVerticalThickness ] )

Required Arguments

  • multiArguments : A table contains at least 1 group of the radius of the corner. The structure is as follows:
{
	{ float LeftTopRadius, bool relative },
	{ float RightTopRadius, bool relative },
	{ float RightBottomRadius, bool relative },
	{ float LeftBottomRadius, bool relative },
}

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • color : An int of the color of the rounded rectangle.
  • background: A texture element of the background of the rounded rectangle.
  • colorOverwritten : A bool indicates whether the final color will be overwritten by color or the product of render color and color when rendering.

Returns

Returns a dgs-dxquad element (dgs Type)/ shader (element Type) if succeed, false otherwise

Example

DGS = exports.dgs --get exported functions from dgs

local quad = dgsCreateQuad({
	{20,10,false},
	{80,10,false},
	{90,90,false},
	{10,90,false},
},tocolor(255,255,255,100))
dgsQuadSetColorOverwritten(quad,false)

local btn = dgsCreateButton(500,400,400,50,"Button",false)
dgsSetProperty(btn,"image",quad)
