C# Read Byte [] to Image
- by LucasGuitar
I have an application which I'm adding pictures and these are automatically converted to binary and stored in a single file. how can I save several images, I keep in an XML file start and size of each set of refente to an image byte. But it has several images in bytes, whenever I try to select a different set of bytes just opening the same image. I would like your help to be able to fix this and open different images.
Code
//Add Image
private void btAddImage_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog op = new OpenFileDialog();
op.Title = "Selecione a Imagem";
op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" +
"JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" +
"Portable Network Graphic (*.png)|*.png";
if (op.ShowDialog() == true)
{
imgPatch.Source = new BitmapImage(new Uri(op.FileName));
txtName.Focus();
}
}
//Convert Image
private void btConvertImage_Click(object sender, RoutedEventArgs e)
{
if (String.IsNullOrEmpty(txtName.Text))
{
txtName.Focus();
MessageBox.Show("Preencha o Nome", "Error");
}
else
{
save(ConvertFileToByteArray(op.FileName), txtName.Text);
}
}
//Image to Byte Array
private static byte[] ConvertFileToByteArray(String FilePath)
{
return File.ReadAllBytes(FilePath);
}
//Save Binary File and XML File
public void save(byte[] img, string nome)
{
FileStream f;
long ini, fin = img.Length;
if (!File.Exists("Escudos.bcf"))
{
f = new FileStream("Escudos.bcf", FileMode.Create);
ini = 0;
}
else
{
f = new FileStream("Escudos.bcf", FileMode.Append);
ini = f.Length + 1;
bin = new TestBinarySegment();
}
bin.LoadAddSave("Escudos.xml", "Brasileiro", nome, ini, fin);
BinaryWriter b = new BinaryWriter(f);
b.Write(img);
b.Close();
f.Dispose();
}
//Load Image from Byte
private void btLoad_Click(object sender, RoutedEventArgs e)
{
getImageFromByte();
}
//Byte to Image
public void getImageFromByte(int start, int length)
{
using (FileStream fs = new FileStream("Escudos.bcf", FileMode.Open))
{
byte[] iba = new byte[fs.Length+1];
fs.Read(iba, start, length);
Image image = new Image();
image.Source = BitmapFrame.Create(fs, BitmapCreateOptions.None,
BitmapCacheOption.OnLoad);
imgPatch2.Source = image.Source;
}
}
