gif animation

It is very convenient to write programs with MATLAB to make gif animations with arbitrary settings, only a dozen lines of code.

Demo1:

The example shows a change from 1 to 10, with a texture attached, the code is as follows:

%% gif images can only display 256 colors, so only index images are supported
filename = 'mygif';
image = uint8(255*zeros(480,640));
image = cat(3,image,image,image);

for i = 1:10
    %% text
    RGB = insertText(image,[200,240],num2str(i),...
        'FontSize',100,'font','LucidaSansRegular','BoxColor',...
        'green','TextColor','red');
    
    %% write
    [im,map] = rgb2ind(RGB,255);
    if i==1
        imwrite(im,map,filename,'gif','LoopCount',inf,'DelayTime',1);
    else
        imwrite(im,map,filename,'gif','WriteMode','append','DelayTime',1);
    end
end

This is the official timing, please wait patiently~

function createGIF2()
% Create a personalized GIF animation Demo
%
A = ones(480,480);
positions = 0.4*[size(A,2),size(A,1)];
positions(2,:) = 0.1*[size(A,2),size(A,1)];

dispnumber = 10:-1:0;
image = imread('lena.jpg');% Enter your own image here
Num = length(dispnumber);
imageNum = 1;%length(imds.Files);

for i = 1:Num+imageNum
    if i<= Num
        RGB = insertText(A,positions,{num2str(dispnumber(i)),'Please wait...'},...
            'BoxOpacity',0,...
            'FontSize',60,...
            'textcolor','r',...
            'Font','Simsun');% 宋体
    else
        C = {'Am I beautiful? ',' Still looking at me? ',' Still looking at me? ? '};
        str = sprintf('%s\n%s\n%s',C{:});
        RGB = insertText(image,0.07*[size(image,2),size(image,1)],...
            str,...
            'BoxOpacity',0,...
            'FontSize',100,...
            'Font','STXingkai',...% Chinese Xingkai font
            'TextColor','g');
        RGB = imresize(RGB,size(A));    
    end
    
    %% write
    [ind,map] = rgb2ind(RGB,255);
    if i == 1
        imwrite(ind,map,'mygif1.gif','gif',...
            'LoopCount',inf,...
            'DelayTime',0.8);
    elseif i == Num+imageNum
        imwrite(ind,map,'mygif1.gif','gif',...
            'WriteMode','append',...
            'DelayTime',3);
    else
        imwrite(ind,map,'mygif1.gif','gif',...
            'WriteMode','append',...
            'DelayTime',1);
    end  
end
