.NET Forum / Windows Forms / Drawing / June 2004Open image : Out of memory exception
I got an out of memory exception when trying to open a tif file. But the tif file can be opened from windows imaging. MSDN mentioned that an out of memory exception will be thrown "If the file does not have a valid image format or if GDI+ does not support the pixel format of the file" How I can open such a file with .NET(C#)? Is there anyway to work around? Thanks a lot for your advice Do you happen to know the picel format? Tiff is such a broad spec it virtually impossible for every reader to read every sort of image that can be stored as a tiff.

Also, it keeps the image as 1-BitPerPixel (for B&W images) so less memory is required. > I got an out of memory exception when trying to open a tif file. > But the tif file can be opened from windows imaging.
