FreeImage support for other images

    I could have sworn that I saw somewhere that FreeImage has plugin support for Nikon .NEF files, among others. Am I dreaming?

    If there is other support, where is it?

      You are dreaming :)
      However, the support for NEF images is planned for a future release.
      Today, you can use dcraw to convert your images to 24-bit ppm and load them with FreeImage. See

    using vb vrapper, imgFormat = FIF_RAW

    dib = FreeImage_Load(imgFormat, fFileName, RAW_DISPLAY)

    It is opening D300s camera raw file for like 5s, while irfanview opens it instantly, furthermore images opened are much darker that those opened with iv.

    Any advice on that ?

    About the speed, you could use the RAW_PREVIEW flag in order to get the embedded JPEG.
    The RAW_DISPLAY flag load the image as 48-bit and convert to 24-bit with a simple bit shifting (that's why the image looks dark). You should use the RAW_DEFAULT load flad to load the image as 48-bit, then use a tone mapping operator to convert the image as 24-bit.
