![]() It isn't the most elegant approach, if some one has another please post. ![]() It requires at least the amount of free ram as the file size you are working on, but it runs fast and file size isn't an issue with most TIFF's. ![]() the stripLabel method is specifically meant to remove the second to last page/directory and shift the last one up, but it should in theory work for any directory other than the last, and it could be easily modified to remove the last too. Offset = long(unpack('L', fmap))ĭef stripLabel(f, offsetList, labelIndex):įmap = fmap TagValue = int(unpack('H', fmap))Įlif tagValue = 34712 or tagValue = 33003 or tagValue = 33005: #if recognized use a string representation #if the tag is a compression, get the compression SHORT value and This copy only contains the pages that you wanted to keep. In these web browsers, you basically open your PDF and use the virtual PDF printer to make a new copy of your PDF. Print "offset: ", offList, "\t Compression: ", compList A quick and easy way to remove pages from a PDF is to use either Google Chrome or Microsoft Edge. import mmapįilename = raw_input("Input file name: ") I also looked into ImageMagick a bit, but I haven't been able to figure out how to do this there either. What I have tried, I have tried the LibTiff.Net library, found hereĪfter messing with it for awhile I asked the developer about my issue, they said that there wasn't currently support to do that. ![]() The page that I need to remove is very very small compared to the rest of the file, as is the page that may or may not be after it, around 500*500 pixels. If I can just remove the part of the file that I want and not create a new one that will go much faster. I have code that does that already, but as the TIFF files I am working with are around 1.0 gb - 3.0 gb heavily compressed, this is extremely time consuming. And I need to do it with out decompressing the previous pages in the file, so not creating a new TIFF and copying all the pages I still want to that. The page would be either the second to last, or the last page in the file. NET but can move to another language if some one knows how to do it in that language. I need to delete a page from a multipaged TIFF file. ![]()
