Utils for reading pixels from UTextureRenderTarget2D.

待办事项

This class only supports PF_R8G8B8A8 format.

在文件 PixelReader.h 第 34 行定义.

成员类型定义说明

Payload

using FPixelReader::Payload = std::function<void(void *, uint32, uint32, uint32)>

在文件 PixelReader.h 第 38 行定义.

成员函数说明

DumpPixels()

TUniquePtr< TImagePixelData< FColor > > FPixelReader::DumpPixels ( UTextureRenderTarget2D & RenderTarget )

static

Dump the pixels in RenderTarget.

前置条件

To be called from game-thread.

在文件 PixelReader.cpp 第 100 行定义.

引用了 WritePixelsToArray().

被这些函数引用 SavePixelsToDisk().

这是这个函数的调用关系图:

SavePixelsToDisk() [1/2]

TFuture< bool > FPixelReader::SavePixelsToDisk ( TUniquePtr< TImagePixelData< FColor > > PixelData, const FString & FilePath )

static

Asynchronously save the pixels in PixelData to disk.

前置条件

To be called from game-thread.

在文件 PixelReader.cpp 第 121 行定义.

SavePixelsToDisk() [2/2]

TFuture< bool > FPixelReader::SavePixelsToDisk ( UTextureRenderTarget2D & RenderTarget, const FString & FilePath )

static

Asynchronously save the pixels in RenderTarget to disk.

前置条件

To be called from game-thread.

在文件 PixelReader.cpp 第 114 行定义.

引用了 DumpPixels() , 以及 SavePixelsToDisk().

被这些函数引用 URoadMap::SaveAsPNG(), ASceneCaptureSensor::SaveCaptureToDisk() , 以及 SavePixelsToDisk().

函数调用图:

这是这个函数的调用关系图:

SendPixelsInRenderThread()

template<typename TSensor , typename TPixel >

void FPixelReader::SendPixelsInRenderThread ( TSensor & Sensor, bool use16BitFormat = false, std::function< TArray< TPixel >(void *, uint32)> Conversor = {} )

static

Convenience function to enqueue a render command that sends the pixels down the Sensor's data stream.

It expects a sensor derived from ASceneCaptureSensor or compatible.

Note that the serializer needs to define a "header_offset" that it's allocated in front of the buffer.

前置条件

To be called from game-thread.

Blocks until the render thread has finished all it's tasks.

待办事项

Can we make sure the sensor is not going to be destroyed?

被这些函数引用 SendPixelsInRenderThread().

函数调用图:

这是这个函数的调用关系图:

WritePixelsToArray()

bool FPixelReader::WritePixelsToArray ( UTextureRenderTarget2D & RenderTarget, TArray< FColor > & BitMap )

static

Copy the pixels in RenderTarget into BitMap.

前置条件

To be called from game-thread.

在文件 PixelReader.cpp 第 83 行定义.

被这些函数引用 DumpPixels() , 以及 ASceneCaptureSensor::ReadPixels().

这是这个函数的调用关系图:

WritePixelsToBuffer()

void FPixelReader::WritePixelsToBuffer ( const UTextureRenderTarget2D & RenderTarget, uint32 Offset, FRHICommandListImmediate & InRHICmdList, FPixelReader::Payload FuncForSending )

static

Copy the pixels in RenderTarget into Buffer.

前置条件

To be called from render-thread.
