❔ Help compressing image!
I need help compressing a jpeg that comes in as a base64string. It currently gets compressed via gzip but this is wrong! I want to shrink the image down therefore lowering the res:
using System.IO.Compression;
public static class ImageCompressor
{
// This function takes a base64 string and converts it into a bytes array.
// The bytes array is then saved in memory, is passed into GZIP which compresses it.
// Flush and Close Gzip.
// Then it returns what we saved in memory as an array.
// We then Convert it back into base64 string
public static string Compress(string oldImage)
{
byte[] imageBytes = Convert.FromBase64String(oldImage);
byte[] compressedData = CompressBytes(imageBytes);
string compressedBase64String = Convert.ToBase64String(compressedData);
// For testing
Console.WriteLine(compressedBase64String);
return oldImage;
}
private static byte[] CompressBytes(byte[] inputBytes)
{
using (var ms = new MemoryStream())
{
using (var gzip = new GZipStream(ms, CompressionMode.Compress))
{
gzip.Write(inputBytes, 0, inputBytes.Length);
}
byte[] compressedStream = ms.ToArray();
return compressedStream;
}
}
}using System.IO.Compression;
public static class ImageCompressor
{
// This function takes a base64 string and converts it into a bytes array.
// The bytes array is then saved in memory, is passed into GZIP which compresses it.
// Flush and Close Gzip.
// Then it returns what we saved in memory as an array.
// We then Convert it back into base64 string
public static string Compress(string oldImage)
{
byte[] imageBytes = Convert.FromBase64String(oldImage);
byte[] compressedData = CompressBytes(imageBytes);
string compressedBase64String = Convert.ToBase64String(compressedData);
// For testing
Console.WriteLine(compressedBase64String);
return oldImage;
}
private static byte[] CompressBytes(byte[] inputBytes)
{
using (var ms = new MemoryStream())
{
using (var gzip = new GZipStream(ms, CompressionMode.Compress))
{
gzip.Write(inputBytes, 0, inputBytes.Length);
}
byte[] compressedStream = ms.ToArray();
return compressedStream;
}
}
}
