Cannot decode the image with very large resolutions using Windows Imaging Component (WIC)

Question

Hi,

Would you please tell me whether there is a limit to the images processed by Windows Imaging Component (WIC) and the maximum resolution of images that can be processed.

Image data to be processed:
Picture specifications
Byte size: 133M
Format: BMP
Resolution: 600DPI
Height: 56173
Width: 19866
Bit depth: 1

Code:

 CoInitialize(NULL);
 IWICImagingFactory* pFactory = NULL;
 IWICBitmapClipper* pIClipper = NULL;
 IWICBitmapDecoder *pIDecoder = NULL;
 IWICBitmapFrameDecode *pIDecoderFrame = NULL;
 IWICBitmapFrameEncode *piFrameEncode = NULL;
 IWICStream *piFileStream = NULL;
 IWICBitmapEncoder *piEncoder = NULL;
 WICPixelFormatGUID pixelFormat = { 0 };


 HRESULT hr = CoCreateInstance(
 CLSID_WICImagingFactory,
 NULL,
 CLSCTX_INPROC_SERVER,
 IID_PPV_ARGS(&pFactory)
 );
 if (FAILED(hr))
 {
 goto CLEAN;
 }
   //Error is caused at below line
 hr = pFactory->CreateDecoderFromFilename(
 originalPath,
 NULL,
 GENERIC_READ,
 WICDecodeMetadataCacheOnDemand,
 &pIDecoder
 );

Error Msg shown is:
Message :WINCODEC_ERR_UNKNOWNIMAGEFORMAT(0x88982f07)

Thanks in advance!!!

Hello,

There seems a limitation that when the dimensions of a bitmap image larger that 27000 * 19883 (or 56173 * 9556), it will not be displayed successfully (via File Explorer preview or Photos etc.) Meanwhile, CreateDecoderFromFilename results in error WINCODEC_ERR_UNKNOWNIMAGEFORMAT(0x88982f07).

Error message displayed in Photos like this:

So please check if the image can be displayed on Windows.

Thank you!
