7. Save 12-bits image

Although raw images store data using a 16-bit integer, the actual data typically uses 12-bit. Saving an image with a 12-bit bit depth can reduce storage requirements while preserving image quality.

#include "P1Image.hpp"
#include <iostream>


using namespace P1::ImageSdk;

int main()
{
    try
    {
        // 1. Load IIQ image
        RawImage im("Sample.IIQ");

        // 2. Convert
        ConvertConfig config;
        // Use at least 12-bit bitmap
        config.SetOutputFormat(BitmapFormat::Rgb48);

        BitmapImage bmp = im.Convert(config);

        // 3. Export to Tiff
        TiffConfig tiffConfig;
        tiffConfig.commonConfig.outputBitDepth = BitDepth::U12;
        TiffWriter("out.tiff", bmp, im, tiffConfig);

        return 0;
    }
    catch (const std::exception& e)
    {
        std::cerr << e.what();
        return -1;
    }
}

using P1.ImageSdk;

// 1. Load IIQ image
RawImage im = new("Sample.IIQ");

// 2. Convert
ConvertConfig config = new();
// use at least 12-bit bitmap
config.SetOutputFormat(BitmapFormat.Rgb48);

IBitmapImage bmp = im.Convert(config);

// 4. Export to Tiff
TiffConfig tiffConfig = new();
tiffConfig.commonConfig.outputBitDepth = BitDepth.U12;

im.WriteAsTiff("out.tiff", bmp, tiffConfig);

Note

Both JPEG, JPEG 2000 (JP2), and TIFF support 12-bit bit depth.
