hi i converted some P5 type .pgm images to .jpg using x=Image.open("oldimage.pgm") imsz=x.size newimg=Image.new('L',imsz) newimg.putdata(x.getdata()) newimg.save("newimg.jpg")
when i again check the pixel data for these images using getdata() method i,I find that they are slightly different ie if oldimage.pgm has pixels [29 31 38 ..., 10 4 18] then the corresponding jpg image has [29 31 38 ..., 10 3 17] why this difference? shouldn't they be identical?can someone pls explain this? -- http://mail.python.org/mailman/listinfo/python-list
