5 Offer a preference to not create thumbnails in the name of speed
6         Accomplish this with special case param of thumb_size = 0 to gm.thumb
7         This will still return the date taken but will not actually do the thumbing

11 In case we ever want to set PROPER EXIF orientation rather than actually rotating pixels,
12 here is the C code:
13
14 long orient = exif["Exif.Image.Orientation"].toLong();
15 if (1 > orient || 8 < orient) {
16         orient = 1;
17 }
18 switch (orient) {
19         case 1:
20                 if (90 == degrees) {
21                         orient = 6;
22                 } else if (-90 == degrees || 270 == degrees) {
23                         orient = 8;
24                 }
25         break;
26         case 2:
27                 if (90 == degrees) {
28                         orient = 5;
29                 } else if (-90 == degrees || 270 == degrees) {
30                         orient = 7;
31                 }
32         break;
33         case 3:

45                 }
46         break;
47         case 5:

59                 }
60         break;
61         case 7:
62                 if (90 == degrees) {

149 cal     : i assume there's a good reason why we can't build the xpcom objects in msys/mingw?
150 richard : um
151 richard : i don't think so but i don't completely understand the compatibility issues between binaries out of visual studio and binaries from msys
152 richard : er, mingw's g++
