Does anybody have any ideas why a simple jpg to tiff conversion leads
to a corrupted tiff file on OSX 10.4 PPC?
I'm using the following code:
using System;
using System.Drawing;
using System.Drawing.Imaging;
public class Test{
public static void Main(string[] args){
using(var photo = new Bitmap(args[0])){
using(var output = new FileStream(args[0]+".tiff",
FileMode.Create)){
output.SetLength(0);
photo.Save(output,ImageFormat.Tiff);
}
}
}
}
The resulting tiff file is unreadable when produced by mono 2.0.1 on
osx, and works just fine using mono 1.9.1 on linux.
When I compare the two files using "cmp -l good.tiff bad.tiff" the
output I receive is:
1 111 115
2 111 115
3 52 0
4 0 52
5 10 0
6 300 0
7 22 0
19 20 377
2579 30 377
5139 43 377
7699 51 377
10259 47 377
12819 43 377
15379 43 377
17939 46 377
20499 0 377
23059 120 377
25619 117 377
28179 50 377
30739 63 377
33299 37 377
35859 3 377
38419 44 377

The interesting thing is that after the first 7 bytes, the bad value
is always listed as 377, and the offset between bad bytes is 2560.
So this seems like a bug in mono, but I wanted to ask just to make
sure that I'm not doing anything stupid. Thanks!
