Problem when editing large-size TIFF-image

[mwarden]

I have a problem editing a big tiff-image (14392 x 158092 x 1)

The tiff-image is created by an OCE TDS400-Scanner. As the scanner-image is rotated and too big, I want to rotate it and cut its top off.

1) rotating
I open the picture, rotate it 90° to the left and then save it under a new name. When opening the image again, it shows the correct size (158092 x 14392 x 1), but only the first (leftmost) approx. 27500 x 14392 pixels of the image show, the rest is simply black.
The tiff-writing parameters are on "LZW+Predict." for color and LZW for black&white

2) selecting
When i try to select any section of the original image for pasting into a new picture, I get a system error "unknown software exception" (0x00000094) at address 0x004a3ef0

Some other edits work without problem. E.g. if i try to change the canvas size to 6500 x 158092, the image is cropped correctly, also after saving and reopening.

I am using XnView 1.91.4 on WindowsXP SP2 with all current security patches installed.

The version XnView 1.82.4 that i was using until yesterday had a similar bug for previewing and viewing the same picture: it cut off approximately the same portion. That seems to work in the new version.

Thanks

(I am a new poster: it seems i can only link to images published on the internet. I have no easy way of publishing the image in question this way. Let me know if you need it for reproducing the mistake. Size approx 1.5MB)

Could you send me the file or post it?
