问题 I want to crop an image to its smaller size, by cutting the white areas on the borders. I tried the solution suggested in this forum Crop a PNG image to its minimum size but the getbbox() method of pil is returning a bounding box of the same size of the image, i.e., it seems that it doesn't recognize the blank areas around. I tried the following: >>>import Image >>>im=Image.open("myfile.png") >>>print im.format, im.size, im.mode >>>print im.getbbox() PNG (2400,1800) RGBA (0,0,2400,1800) I

Suppose the unpadded image was a BufferedImage and is called 'image'. Suppose the amount of whitespace you want on each side is 'w'. What you want to do is create a new BufferedImage wider than the

问题 I would like to Scale, Move, Resize Image. I would like to surround the image with Indicators which guide user what operation these indicators perform i.e. Moving, Rotating, Scaling. I've tried Scaling - but it only crops down. No chance to increase length and height of image. Rotate - achieved but via inserting manual degrees. That's not a good option in here. Moving - as I'm achieving drag on Api < 11. So little bit of difficult. Still no hope in here. Is there any library which can do me

问题 Is there a MATLAB function that does the following: For an image input, it tells me what proportion of the bits are darker than a particular color of my choosing. So if I entered an image of a chess board and used the color gray, the output would be roughly one half. (the image I need to process in this way is not that simple, though) 回答1: function CompareMap = BitWiseCompare('filename',c) % c = [R , G , B]; A = imread('filename'); CompareMap = zeros([size(A,1),size(A,2)]); CompareMap = (A(:,
