I'm a long time user of ImageEn with an application currently using version 3.1.1. For the first time, I've got a user that has a bunch of TIFF files that I can't read.
I tested them using the PhotoEditor demo application I just downloaded from here and the results are strange, the OpenFile dialog preview shows the contents, but when I click OK, I don't actually see anything. When I select File|Properties in the demo it displays a dialog that says 0x0 pixel, 24 bit color, 444KB size, and 300x300 dpi.
Windows 7 shows the image natively just fine. Properties in Windows 7 shows 96x96 dpi, 816x1056 pixels, 96 dpi, and 32 bit color.
I'm afraid it's a medical image so I can't give you a copy of the file to look at. If I "recreate" the image by printing it to a file or loading it into Paint and saving it again, that new version works fine so I don't have any way to sanitize the file without eliminating the problem.
Any thoughts would be appreciated! |

I just noticed that in the Windows 7 properties dialog, in the Details tag, that the only information it lists is:
- Dimensions: 816x1056
- Width: 816 pixels
- Height: 1056 pixels
- Horizontal resolution: 96 dpi
- Vertical resolution: 96 dpi
- Bit Depth: 32
- Compression:
- Resolution unit:
- Color representation:
- Compressed bits/pixel:
Note that all of the last ones are blank, which isn't typical of other TIFF images I've checked. Hopefully this will mean something significant to someone!
Thanks! |

Unfortunately without an image to test I cannot help. Consider that the preview tries to read a thumbnail if present, so maybe ImageEn can only read the embedded thumbnail and fails to read the actual image.
Anyway try this:
1) load the image using LoadFromFileAuto
2) maybe the image is a raw file. Install the dcrawlib and try to open using LoadFromFileRAW
...3) send a copy of the image to xequte... |
