Image.FromStream don't work the same way on my new windows installation
I've got this test that used to works on my old machine. (Windows Vista Ultimate 32-bit)
开发者_如何学Cprivate static readonly byte[] TEST_BMP = new byte[]
{
0x42, 0x4D, 0x7E, 0, 0, 0, 0, 0, 0, 0, 0x76, 0, 0, 0, 0x28, 0, 0, 0, 0x2,
0, 0, 0, 0x2, 0, 0, 0, 0x1, 0, 0x4, 0, 0, 0, 0, 0, 0x8, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0x80, 0, 0, 0x80,
0, 0, 0, 0x80, 0x80, 0, 0x80, 0, 0, 0, 0x80, 0, 0x80, 0, 0x80, 0x80, 0, 0,
0x80, 0x80, 0x80, 0, 0xC0, 0xC0, 0xC0, 0, 0, 0, 0xFF, 0, 0, 0xFF, 0, 0, 0,
0xFF, 0xFF, 0, 0xFF, 0, 0, 0, 0xFF, 0, 0xFF, 0, 0xFF, 0xFF, 0, 0, 0xFF,
0xFF, 0xFF, 0, 0x40, 0, 0, 0, 0xF9, 0, 0
};
[Test]
public void Can_get_Image_from_BMP_Stream()
{
using (var memStream = new MemoryStream(TEST_BMP))
{
Image image = Image.FromStream(memStream);
Assert.NotNull(image);
}
}
On my new machine (Windows 7 64-bit) it doesn't work anymore.
I get this exception:
System.ArgumentException : Parameter is not valid.
at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)
at System.Drawing.Image.FromStream(Stream stream)
at Litium.Framework.Image.Test.ImageManagerTests.Can_get_Image_from_BMP_Stream()
If I instead try with this it works...
private static readonly byte[] TEST_GIF = new byte[]
{
0x47, 0x49, 0x46, 0x38, 0x39, 0x61, 0x2, 0, 0x2, 0, 0x11, 0, 0, 0x2C, 0, 0
, 0, 0, 0x2, 0, 0x2, 0, 0xA1, 0xFF, 0, 0, 0xFF, 0xFF, 0xFF, 0, 0, 0, 0, 0,
0x80, 0x2, 0x3, 0xC, 0x26, 0x5, 0, 0x3B
};
Why doesn't this work on my new machine?
Have you tried adding an extra 0 byte at the end? I have a good feeling about that!
