Re: fetch jpeg image dimension without load it small_programmer3-Jul-07 3:00 small_programmer 3-Jul-07 3:00  thank you . but can you offer a formula between density and unit that result in the height and width in pixel. if you do it i will thank you very much Re: fetch jpeg image dimension without load it Colin Angus Mackay3-Jul-07 3:43 Colin Angus Mackay 3-Jul-07 3:43  Well, according to the link. If units is zero then Xdensity and Ydensity are already in pixels. If it is 1 or 2 it is in dots per inch or cm respectively. You will then need to find out the dots per inch/cm on the output device and scale appropriately. For example, if the image is a photo at 300dpi and it is to be displayed on a screen at 96dpi then you need to reduce the number of pixels by source/destination or 300/96 (3.125) Upcoming events: * Glasgow: Mock Objects, SQL Server CLR Integration, Reporting Services, db4o, Dependency Injection with Spring ...

Re: fetch jpeg image dimension without load it [modified] small_programmer3-Jul-07 4:50 small_programmer 3-Jul-07 4:50  it does not give me the height and width in pixel yet. i want only height and width. unit and density does not help me thank you again. How to save images into Access DataBase AR Reddy3-Jul-07 2:15 AR Reddy 3-Jul-07 2:15  Hi, I want to save the images into Access database in C#.

You can save the data to a file or the registry when you exit, and simply read them when you start again. Cheers, Vıkram. After all is said and done, much is said and little is done. Problem with MemorySream wesch3-Jul-07 1:58 wesch 3-Jul-07 1:58  Why does the following code snippet MemoryStream stream = new MemoryStream(); XmlTextWriter writer = new XmlTextWriter(stream, Encoding.UTF8); writer.WriteStartDocument(); writer.WriteElementString("Test", "Test"); writer.WriteEndDocument(); writer.Flush(); stream.Seek(0, SeekOrigin.Begin); Console.WriteLine(Encoding.UTF8.GetString(stream.ToArray())); produce the following output: ?<test>Test The question mark at the beginning is meant. I've tried different encodings, it does not happen with Default and ASCII. When I use a StreamReader I can get it to work, but I will understand where the problem is. Re: Problem with MemorySream WillemM3-Jul-07 2:31 WillemM 3-Jul-07 2:31  Let me try that piece out... Looks interesting. It has something to do with the number of bytes in a character. The "old" ASCII uses 7 bits, while UTF8, you guessed it uses 8 bits. But it doesn't really explain why you get the weird character at the beginning. Have you tried looking up some info about text encoding on google? Re: Problem with MemorySream wesch3-Jul-07 2:37 wesch 3-Jul-07 2:37  Yes, I've tried to find some hints on Google but without success. Console.WriteLine(new StreamReader(stream).ReadToEnd()); works correct. Re: Problem with MemorySream Luc Pattyn3-Jul-07 2:42 Luc Pattyn 3-Jul-07 2:42  when you create a stream or file in UTF8 or in Unicode, it will start with a 2-byte indication of the encoding; in your case it is 0xFE 0xBB. Only then will appear the first "real" character (0x3C for <). If you write to file, then open the file in a text editor, both cases work just fine, because the editor consumes the optional 2-byte to understand how it needs to interpret the remainder. Your reading code however does not discover the encoding, it has that information baked into the code, so it treats the 0xFE oxBB as real characters and since they are not really printable (above 0x7E), it turns them into a single question mark.
