How to reduce time while converting j2k image to bitmap using MagickImage dll?

Feb 13, 2014 at 6:05 AM
I am loading j2k images(by converting into Bitmap) using MagickImage.dll in c#.

sample code of loading j2k image in c# is :
 MagickImage image = new MagickImage(fileName);
  Bitmap bitmap= image.ToBitmap();
It is loading properly but taking a long time for e.g. 10-12 seconds per image. Can anybody tell how to reduce the time while converting image to Bitmap?

Thanks in advance.

Can you post them on dropbox or contact me through Codeplex to email them to me? And which version of Magick.NET are you using?

Can you first upgrade to the latest version and see if you can replicate the problem? The links to your images are not working.

Press the 'DOWNLOADS' button in the menu to get the latest version. I will try if I can reproduce your problem with the latest version during my lunch break.

Thank you.
is this a latest version?
I am facing same problem with this.

You are now using the latest version. The problem seems to be that ToBitmap now uses ImageFormat.Png to create the bitmap. When you use ToBitmap(ImageFormat.Bmp) the bitmap will be created much faster. I will make ImageFormat::Bmp the default in the next version of Magick.NET.

I have checked that by using ToBitmap(ImageFormat.Bmp).It gives me error for some images,
i.e. "MagicK: unable to decode image file".

That error message is from reading an incorrect j2k file. Changing ToBitmap() to ToBitmap(ImageFormat.Bmp) should not not affect this.
