Hi,
Of course, looks interesting. Can you provide us with a sample pdf?
Please create an issue on JIRA [1] and attach both the patch and the
sample pdf to it.
I created an issue on JIRA.

Hi,
Hi,
I understand that PDFToImage currently doesn't support drawing
vertical text like Identity-V encoding. But I had to use it,
so I tried to let it work with modification as show below.
Even though I don't know whether this code is proper or not, I
could make image files with vertical text PDF file.
I'm happy if this information is something useful.
