Methods
Begin(GraphicsContext, ref Matrix, BlendStateDescription?, SamplerState, RasterizerStateDescription?, DepthStencilStateDescription?, int)
Begins a image batch rendering using the specified blend state, sampler, depth stencil, rasterizer state objects, and the view-projection transformation matrix. Passing null for any of the state objects selects the default default state objects (BlendState.AlphaBlend, DepthStencilState.None, RasterizerState.CullCounterClockwise, SamplerState.LinearClamp).
public void Begin(GraphicsContext graphicsContext, ref Matrix viewProjection, BlendStateDescription? blendState, SamplerState samplerState, RasterizerStateDescription? rasterizerState, DepthStencilStateDescription? depthStencilState, int stencilValue)Parameters
graphicsContextGraphicsContextThe graphics context to use.
viewProjectionMatrixThe view projection matrix used for this series of draw calls
blendStateBlendStateDescription?Blending options.
samplerStateSamplerStateTexture sampling options.
rasterizerStateRasterizerStateDescription?Rasterization options.
depthStencilStateDepthStencilStateDescription?Depth and stencil options.
stencilValueintThe value of the stencil buffer to take as reference

sourceRectangleRectangleFThe rectangle indicating the source region of the texture to use
elementSizeVector3The size of the ui element
borderSizeVector4The size of the borders in the texture in pixels (left/top/right/bottom)
colorColorThe color to apply to the texture image.
depthBiasintThe depth bias of the ui element
imageOrientationImageOrientationThe rotation to apply on the image uv
swizzleSwizzleModeSwizzle mode indicating the swizzle use when sampling the texture in the shader
snapImageboolIndicate if the image needs to be snapped or not
DrawRectangle(ref Matrix, ref Vector3, ref Color, int)
Draw a rectangle of the provided size at the position specified by the world matrix having the provided color.
public void DrawRectangle(ref Matrix worldMatrix, ref Vector3 elementSize, ref Color color, int depthBias)Parameters
