我正在尝试在matlab中创建一个闪烁的棋盘格movie()
。我正在使用以下代码创建框架:
close all;
n=80; % length of checkerboard squares in pixels
p=5; % number of checkerboard rows
q=6; % number of checkerboard columns
loops=100;
A=zeros(p*n,q*n,2);
my_checkerboard=logical(checkerboard(n,p,q));
A(:,:,1)=double(my_checkerboard(1:p*n,1:q*n));
A(:,:,2)=ones(p*n,q*n);
%A(:,:,2)=double(~my_checkerboard(1:p*n,1:q*n));
F(loops)=struct('cdata',[],'colormap',[]);
h=figure;
for ii=1:1000
figure(h);
imshow(A(:,:,mod(ii,2)+1));
drawnow;
F(ii)=getframe;
end
现在,如果我正在播放这样的电影
close all;
h=figure;
movie(h,F,1,10)
我将能够通过绘制图形的角来缩放影片。但是,如果我像这样以前缩放数字
close all;
h=figure('Position',[2640,280,960,800]);
movie(h,F,1,10)
电影不会按照人物比例缩放。相反,电影将在图的左下角播放。
我感觉这不仅可以缩放图形,还可以缩放轴,但是我不知道该怎么做。
编辑:如果有人可以将gif生成器上的某些资源链接到我,我也将很高兴,它可以轻松地创建具有可定制数量的图块的可扩展的闪烁棋盘。

我认为MATLAB movie
...中有一个错误
以下代码在大多数情况下有效:
close all;
n=80; % length of checkerboard squares in pixels
p=5; % number of checkerboard rows
q=6; % number of checkerboard columns
loops=100;
A=zeros(p*n,q*n,2);
my_checkerboard=logical(checkerboard(n,p,q));
A(:,:,1)=double(my_checkerboard(1:p*n,1:q*n));
A(:,:,2)=ones(p*n,q*n);
%A(:,:,2)=double(~my_checkerboard(1:p*n,1:q*n));
F(loops)=struct('cdata',[],'colormap',[]);
h=figure;
for ii=1:10
figure(h);
%imshow(A(:,:,mod(ii,2)+1));
imshow(A(:,:,mod(ii,2)+1), 'Border', 'tight'); %Show image without borders
drawnow;
F(ii)=getframe;
end
savefig(h, 'h.fig') %Save the figure to a file, (not the best solution).
%Playing the movie
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
close all;
h = openfig('h.fig'); %Load the figure
% h=figure;
movie(h,F,1,10)
保存和加载图形只是保持原始图形尺寸的一种简单方法。
