I"ve got things working now and use numpy to convert bluelines to SVG lines or
a python tuple that gets written out.
It could be of general interest for vectorizing if it treated a selection.
But I am converting scanned stripcharts, and the ink is blue... One y per x is
all I need, and there would be a slick way to do that with numpy; I"m just
using a stride for line thinning.
The part I dont understand is this; I pass my bluemask to (Fremlin"s)
write_out(drawable, image) as the image, it fails the assertion and does not
post...
numpy.array((image*256).round(0),"B")
def write_out(drawable, image):
"""by John Fremlin"""
byte_image = numpy.array((image*256).round(0),"B") # B is a ubyte
width = drawable.width
height = drawable.height
bpp = drawable.bpp
sys.stderr.write("write_out::drawable.width=%i drawable.height=%i
drawable.bpp=%i\n" % (width, height, bpp))
pr = drawable.get_pixel_rgn(0, 0, width, height, True)
assert(byte_image.size == width * height * bpp)
pr[:,:] = byte_image.tostring()
