It would be nice to have api support for generating the pHYs section, as it is part of the PNG Specification.
It's possible to do it manually if there is already a chunk:
stream.each_chunk do |c|
if c.type == 'pHYs'
c.content = [5906, 5906, 1] .pack('N2C')
end
end
But it's not as easy to insert this node into a fresh PNG. I plan on inserting a ChunkyPNG::Chunk::Generic into #other_chunks, but this feels really a tad dirty. I propose that Datastream have ChunkyPNG::Chunk::Phys and a corresponding phys_chunk accessor.
