问题描述
我有一组图像,这些图像已经布置成矩形,看起来像拼贴画。如何在Ruby中拍摄这些图像并从中创建单个图像?
I have a collection of images that have been laid out in a rectangle to look like a collage. How can I take those images and create a single image out of them in Ruby?
例如,我想在图像中放置三个图像,如下所示:
For example I have three images that I want placed in the image as follows:
图片1:(0,0) - (300,400)
Image 1: (0,0) - (300,400)
图片2:(350,0) - ( 500,200)
Image 2: (350, 0) - (500, 200)
图3:(350,220) - (500,400)
Image 3: (350, 220) - (500, 400)
推荐答案
你可以用RMagick尝试这样的事情:
You can try something like this with RMagick:
require 'RMagick'
bg = Image.read('bg.png') # may be a background image...
image1 = Image.read('image1.png')
image2 = Image.read('image2.png')
image3 = Image.read('image3.png')
bg.composite!(image1, 0, 0, OverCompositeOp)
bg.composite!(image2, 350, 0, OverCompositeOp)
bg.composite!(image3, 350, 220, OverCompositeOp)
bg.write('collage.png')
