kfblibrary

A third-party library for kfb format whole slide image.

Usage

Compile this project and then replace libkfbslide.so. For the API usage, you can refer to main.cpp.

Why re-implement libkfbslide?

I find there is some memory leak issues in the raw libkfbslide.so, which crashs my model training process. Therefore, I re-implement the library, and add deallocation API and auto buffer deallocation in the kfbslide_close.

1. libkfbslide.so will load associate_images in kfbslide_open(), which slows down the performance.
2. All image data buffers allocated by libImageOperationLib.so will not be freed by the library.

In this project, I only re-implement all apis in libkfbslide.so. However, some operations in libImageOperationLib.so are not been implemented, including:

(functions reading properties)
    GetGetImageBarCodeFunc
    GetImageChannelIdentifierFunc
    GetMachineSerialNumFunc
    GetScanLevelInfoFunc
    GetScanTimeDurationFunc
    GetVersionInfoFunc
    
(functions reading data from filepath)
    GetLableInfoPathFunc
    GetPriviewInfoPathFunc	
    GetThumnailImageOnlyPathFunc
    GetThumnailImagePathFunc

(maybe concurrent loading)
    GetLUTImageManyPassageway
    GetImageStreamManyPassagewayFunc
    GetImageDataRoiManyPassagewayFunc

GetLUTImage
GetImageRGBDataStreamFunc
UnCompressBlockDataInfoFunc

You can implement this API with the help of IDA Pro.
