A revised way of processing your pdf so you can read on kobo glo
Also you might want to read the original processing flow I mentioned above, before you read what’s below, because many key points and explainations I mentioned in there will not be repeated blow:
Here are the abstract of procedures:
1. Convert the pdf into a set of images (one image per page)
2. Crop all images to get rid of the useless spaces at the margins.
3. Flip all images by 90 degrees to the left (anti-clockwise).
4. Split all images horizontally into either 2 or 3 parts (note, each part should also contain some area of its neighboring parts to guarantee a continuous reading experience, therefore this is the hardest step, not just simply split.)
5. Compose the resulting images into a cbr/cbz.
So basically what you get in the end is a ebook that you can read as if it is in landscape mode in kobo, but with this version you can turn pages very easily. You just have to tap your way to read, without configuring views while reading.
For number step 1, 2, and 5, I have already explained a little bit in the previous procedure, which I will not repeat. Step 3 can be done easily with many massive picture processing softwares.
Now for step 4, you need a good massive picture processing software, and how it is done depends on your own software. For my software, I shall use the so called “capture” feature, which is used to extract certain part of picture, that applies to all pictures of your selection, and save the selected pictures in a specified directory. I use it to produce 2 (can be 3 if you want to) set of pictures, the first set is the upper part of pages (left part of flipped images), the second set is the lower part of the pages (right part of flipped images). Then I use a massive files rename feature (come with the picture processing software), to rename all files in the second set, so when I place pictures from the first and second set together in one directory and sort them by name, the lower part will appear right after the upper part of the same page. Then basically I will go to step 5 to compose them,
So that’s much about it, at least for now.

problem: pdfs containing pictures are big and very slow to display.
Better have some program that splits pages and distributing the letters accordingly. I've seen some programs for this splitting, but have not tried them
I would think of something like this:
extracting letter location, then using pycairo to make new (half) pages ..
maybe easier with pypdf? http://pybrary.net/pyPdf/
