Read HEIC File into Array in C#

This code snippet efficiently loads a HEIC image file, extracts its pixel data in the specified format, and stores it in an array for subsequent operations.

• Open the HEIC file named "filename.heic" using FileStream.
• Load the HEIC image from the file stream into a HeicImage object.
• Extract pixel data from the HEIC image in the ARGB32 format and store it in an integer array.

Copy and paste the code snippet below into your main file and execute the program.

 
using (var fs = new FileStream("filename.heic", FileMode.Open))
{
    HeicImage image = HeicImage.Load(fs);
    int[] pixels = image.GetInt32Array(Heic.Decoder.PixelFormat.Argb32);
}

Read HEIC file into Bitmap in C#

The following code illustrates how to open an existing HEIC image file, extract its pixel data, and create a WriteableBitmap object for further processing:

• Open the HEIC file named "filename.heic" using FileStream.
• Load the HEIC image from the file stream into a HeicImage object.
• Extract pixel data from the HEIC image in the BGRA32 format and store it in an array.
• Get the width and height of the HEIC image.
• Create a WriteableBitmap object with the specified width, height, and pixel format.
• Define a rectangle covering the entire bitmap area.
• Write the extracted pixel data to the WriteableBitmap object.

Copy and paste the code snippet below into your main file and execute the program.

 
using (var fs = new FileStream("filename.heic", FileMode.Open))
{
    HeicImage image = HeicImage.Load(fs);
     
    var pixels = image.GetByteArray(Heic.Decoder.PixelFormat.Bgra32);
    var width = (int)image.Width;
    var height = (int)image.Height;
     
    WriteableBitmap wbitmap = new WriteableBitmap(
        width, height, 72, 72, PixelFormats.Bgra32, null);
    Int32Rect rect = new Int32Rect(0, 0, width, height);
    wbitmap.WritePixels(rect, pixels, 4 * width, 0);
}

Convert HEIC to JPG Programatically in C#

The provided code demonstrates how to programmatically load a HEIC image file, convert it to a JPEG image, and save it as "output.jpg" using C#. Here's a breakdown of the steps:

• Open the HEIC file named "filename.heic" in read mode using FileStream.
• Load the HEIC image from the file stream into a HeicImage object.
• Extract the pixel data from the HEIC image in the BGRA32 format, storing it in a byte array.
• Retrieve the width and height of the HEIC image.
• Create a WriteableBitmap object with the specified width, height, DPI, pixel format, and palette.
• Define a rectangle covering the entire bitmap area.
• Write the extracted pixel data to the WriteableBitmap object.
• Create or open a file stream for saving the converted image as "output.jpg".
• Create a JpegBitmapEncoder object to encode the bitmap as a JPEG image.
• Add the bitmap frame to the encoder.
• Save the encoded image to the file stream.

Copy and paste the code snippet below into your main file and execute the program.

 
using (var fs = new FileStream("filename.heic", FileMode.Open))
{
    HeicImage image = HeicImage.Load(fs);
     
    var pixels = image.GetByteArray(Heic.Decoder.PixelFormat.Bgra32);
    var width = (int)image.Width;
    var height = (int)image.Height;
     
    var wbitmap = new WriteableBitmap(width, height, 72, 72, PixelFormats.Bgra32, null);
    var rect = new Int32Rect(0, 0, width, height);
    wbitmap.WritePixels(rect, pixels, 4 * width, 0);
    
    using (FileStream saveStream = new FileStream("output.jpg", FileMode.OpenOrCreate))
    {
        JpegBitmapEncoder encoder = new JpegBitmapEncoder();
        encoder.Frames.Add(BitmapFrame.Create(wbitmap));
        encoder.Save(saveStream);
    }
}
