I'm trying to convert an input image to a JPEG output image with this code

L_LoadBitmap((LPSTR)lpszName, &m_bmhLEAD, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL)

BITMAPHANDLE * pLeadBM = &m_bmhLEAD;

int iFormat = FILE_JFIF;

iResult = L_SaveBitmapMemory(&m_hFileInMemory, // file comes back here
            pLeadBM,     // the LEAD format BITMAPHANDLE
            iFormat,     //
            0,       // using existing resolution
            0,      // perfect quality (lossless)
            &uMemSize, NULL);

pData = (L_CHAR L_FAR *)::GlobalLock(m_hFileInMemory);
iWidth = pLeadBM->Width;
iHeight = pLeadBM->Height;

I'm attaching the input image and the output image. The output image won't open in any viewer, this is in Leadtools C++ SDK version 14.5.0.43

Do you have any idea what's going wrong?

Attached is the input image, I'll attach the output image in the next comment

Here's the output from Leadtools, as you can see it doesn't open

Most viewers do NOT support Lossless JPEG compression (QFactor = 0). You will be able to open this file with LEADTOOLS and viewers that support lossless JPEG. You need to save with a QFactor of 2-255 to get the most compatibility with other viewers.
