GetImageStream()
Returns the image stream.
public Stream GetImageStream()
Return Value
A stream with the image.
Examples
The following example shows how to save images to files:
// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
// Extract images from document
IEnumerable<PageImageArea> images = parser.GetImages();
// Check if images extraction is supported
if (images == null)
{
Console.WriteLine("Page images extraction isn't supported");
return;
}
// Iterate over images
foreach (PageImageArea image in images)
{
// Open the image stream
using (Stream imageStream = image.GetImageStream())
{
// Create the file to save image
using (Stream destStream = File.Create(Guid.NewGuid().ToString() + image.FileType.Extension))
{
byte[] buffer = new byte[4096];
int readed = 0;
do
{
// Read data from the image stream
readed = imageStream.Read(buffer, 0, buffer.Length);
if (readed > 0)
{
// Write data to the file stream
destStream.Write(buffer, 0, readed);
}
}
while (readed > 0);
}
}
}
}
