Delta row compression in PCLXL

Hi all, Is there a difference in the implementation of delta row compression between PCLXL and PCL5? I was using Delta Row compression in PCL5, but when I used the same method in PCLXL, the file is not valid. I checked the output using EscapeE and it says that the image data size is incorrect.. Could anyone point me to some material e...

Algorithm: Minimal Encoding, Error Correction, Please Help?

Say there's an array of 1024 bits that are all zeros: example: [0,0,0,0,0,0,0,...] Then I overwrite 20 zeros with ones at completely random positions: example: [0,1,0,0,0,0,0,...] What is the theoretical minimum number of bits needed to encode the location of these 20 randomly placed bits, assuming that I had a perfect encoder? I k...
