MATLAB程序：设置图片尺寸与位置

发表于 更新于 分类于

写作高质量的学术文章时，个人认为首先要好看。

有人说，内容重于形式。好吧，我承认你是对的。

学术文章里的图片也是如此，第一个问题：想要2.71828cm*3.14159cm的图片怎么办？

为此，我编写了一个小程序，用于设置图片尺寸与位置。完整代码如下：

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 该脚本用于图像尺寸与位置设置
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% INPUT
% parameter1     :  - 矢量 1x4
% parameter1     =    [fw,fh,fx,fy] 
% parameter1(1)     - 图像宽度, 单位cm
% parameter1(2)     - 图像高度, 单位cm
% parameter1(3)     - 图像在屏幕中比例位置, 水平方向
% parameter1(4)     - 图像在屏幕中比例位置, 铅垂方向
% parameter2     :  - 矢量 1x4
% parameter2     =    [aw,ah,ax,ay] 
% parameter2(1)     - 坐标轴宽度(与图像宽度的比例)
% parameter2(2)     - 坐标轴高度(与图像高度的比例)
% parameter2(3)     - 坐标轴在图像中比例位置, 水平方向
% parameter2(4)     - 坐标轴在图像中比例位置, 铅垂方向
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% OUTPUT            - NONE
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 调用示例1 - 画一个图
% x=rands(10,1);plot(x);figset([8,9,0.1,0.1],[0.8,0.8,0.1,0.1]);
% 调用示例2 - 画多个图
% figure;x1=rands(10,1);plot(x1);figset([8,8,0.1,0.1],[0.8,0.8,0.1,0.1]);
% figure;x2=rands(10,1);plot(x2);figset([5,5,0.5,0.5],[0.8,0.8,0.1,0.1]);
% 调用示例3 - 只输入parameter1
% figure;x1=rands(10,1);plot(x1);figset([8,8,0.1,0.1],[0.5,0.7,0.1,0.2]);
% figure;plot(x1);figset([8,8,0.5,0.5]);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

function figset(parameter1,parameter2)

    %电脑屏幕尺寸
    set(0,'units','centimeters')
    cm_ss=get(0,'screensize');
    W=cm_ss(3);%电脑屏幕长度，单位cm
    H=cm_ss(4);%电脑屏幕宽度，单位cm

    %设置figure在screen中的比例位置与大小
    temp1=[parameter1(3),parameter1(4),parameter1(1)/W,parameter1(2)/H];
    set(gcf,'units','normalized','position',temp1);
    if nargin==2
        %设置axis在figure中的比例位置与大小
        temp2=[parameter2(3),parameter2(4),parameter2(1),parameter2(2)];
        set(gca,'position',temp2);
    end

end

MATLAB（我使用的是R2018b）支持十分友好的属性检查器（Property Inspector）图像化界面，在图像化界面里可以对Figure的所有属性（包括上述函数figset设置的大小与位置）进行傻瓜式操作，MathWorks还是用心了。
