gcf:获取当前显示图像的句柄: 默认 plot 的 position 是 [232 246 560 420] 0. save >> A = randn(3, 4); >> B = 'hello world'; >> save 'data.mat' A B % 将多个对象保存进 data.mat 文件中 >> save data A B % 两个保存语句是等价的: 1. imwrite.saveas.print I = imread('./name.bmp'

一.图片读取保存 (1)读取 clear all [filename,pathname]=uigetfile({'*.jpg';'*.bmp';'*.gif'},'选择图片'); if isequal(filename,0) disp('Users Selected Canceled'); else str=[pathname filename]; im = imread(str); imshow(im); end (2)保存 clear all x=0:0.01:2*pi; plot(x,si
js var url = canvas.toDataURL();//把canvas中的图片变成data:image C# string filepath = ""; string imgData = Request["url"].ToString(); var date = DateTime.Now.ToString("yyyyMMddmsms"); if (imgData.StartsWith("data:image/png;base
