Compactfile inverting images

I am in the process of migrating from one document imaging system to another. When I export a document that is a multipage tif it is exported into individual tiff files. I was using the compactfile method to insert the page into the last page to combine them back together. On some images there will be pages that are inverted (black with white text) I looked at the original image that was exports and it is fine. So is it possible that the compact file method is causing this and if so is there a way to prevent it from happening.

Also because I am getting inverted files I was trying to check the images and verify if they are inverted or not. I was using the codecs.getinformation command, then I would look at the bytesperline and if they were greater than 312 then I would call the invertcommand. It doesn't always work, so I not sure if I have the parameters wrong or not. I was telling it to overwrite the page.

Any help on these issues would be greatly appreciated. I am new to the leadtools sdk, so it might be a lack of knowledge or understand on my part.

Thanks,

I believe you sent this same question via email, so I will give you the same response plus a little extra.

Are all of the source images the same compression and palette?  Sometimes people will have inversion problems when they try to combine 1bpp LZW images and CCITT G4 images together because their palettes are opposites.  Checking the BytesPerLine is close to the idea, but you'd be better off checking the file format or checking the palette after you've loaded it.  You should be able to use the ColorResolutionCommand class on each image to ensure that they are all using the same palette, byte order, etc.

If they are different at times, then you may have to load and save files that differ to ensure that they all have the same compression.

If this does not answer your question, please send a small sample project (NOT your entire application) that isolates the problem you are experiencing so I can try to reproduce it here.
