hi. I am currently working on halftoning in PIL. I need to convert pixels of a certain image into different shapes. I have done that, but I have some problems with: 1) I need to select a few pixels (with for loop I think) and convert them into one shape, because now the image gets a few times bigger than original one. 2) I need to set pixels to become bigger depending on the color value. Could anyone help me with these problems?
