Method Render

Namespace

PaintDotNet.Effects

Assembly

PaintDotNet.Effects.Core.dll

Render(void*, int, nint, in PixelFormat, RectInt32)

Renders the requested area and stores the result in the given buffer. The entire buffer is written to, including areas that are outside of the selection. The caller must perform any masking or blending.

void Render(void* pBuffer, int bufferStride, nint bufferSize, in PixelFormat bufferPixelFormat, RectInt32 renderRect)

Parameters

pBuffer void*

bufferStride int

bufferSize nint

bufferPixelFormat PixelFormat

renderRect RectInt32

Remarks

Most BGRA/RGBA pixel formats can be used for the buffer. If it matches the pixel format that the effect is using for its output buffer, no conversion will be necessary and performance will be optimal. Integer formats such as Bgra32 will be stored in gamma compressed format (e.g. sRGB), while floating point formats such as ColorRgba128Float will use linear gamma.

This method will handle clearing / zero-filling the buffer if necessary based on whether the effect uses UninitializedOutputBuffer. It is never necessary for the caller to clear / zero-fill the buffer before passing it to this method.

Exceptions

InvalidOperationException

Initialize(BitmapEffectInitializeInfo) must be called first.
