MATLAB: Showing GIF images in GUI

gif

I have gif images which are all black and white and I am trying to show them using this code:

for j=1:12
[I cmap] = imread(strcat(path,filename),'frames','all');
subplot(4,3,j)
image(I);
colormap(cmap);
axis off;
axis image;
end

For some images it works but for some displays only black picture

ALL IMAGES ARE BLACK AND WHITE AND IN .GIF FORMAT

If someone knows where is the problem help me please

for j=1:12
  [I cmap] = imread(strcat(path,filename),'frames','all');
  ax = subplot(4,3,j);
  image(I);
  colormap(ax,cmap);
  axis off
  axis image
end

Starting 14b, you can have a separate colormap for each axes, so try this.

Hi, it is difficult to provide exact solution without your variable BBIO and BIO. But I have made some changes in your code to make it behave the way you like. You should assign the changing title to ax1 without setting its visibility to ‘off’. You can refer to the code below.

figure4=figure(4);
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
M4=max((max(reshape(BBIO,503*647,146))'));
% Setting transparency conditions: if the pixel signal is > 0, then in matrix A it is marked as 1 (transparent). Otherwise it is 0 (opaque)
R4=reshape(BIO,503*647,146);
X=15;
for j=1:146
    for i=1:503*647
        if R4(i,j)<X
            R4(i,j)=0;
        else
            R4(i,j)=1;
        end
    end
end
A4=reshape(R4,503,647,146);
% Generating images and saving them into GIF
for i=1:146
    ax1 = axes('Parent',figure4);
    ax2 = axes('Parent',figure4);
    clims=[X M4];
    i1=imagesc(BIO(:,:,i),'Parent',ax2,clims);
    colormap(ax2,jet);
    hold on;
    set(i1,'alphadata',A4(:,:,i));
    colorbar;
    c3=colorbar;
    w=c3.Position;
    c3.Position=[0.860954412414402,0.110072689511942,0.030111111111111,0.815160955347871];
    set(c3,'YTick',[])
    hold on;
    imagesc(BIO_US_double(:,:,i),'Parent',ax1);
    colormap(ax1,gray);
    daspect(ax1,[1 1 1]);
    daspect(ax2,[1 1 1]);
    % Set only ax2 visibility off not ax1
    set(ax2,'Visible','off');
    ax1.XTick = [];
    ax1.YTick = [];
    % Add your changing title to ax1
    title(ax1,['\lambda=',sprintf('%d',2*i+678),'nm']);
    hold off;
    % gif utilities
    drawnow;
    frame = getframe(4);
    im = frame2im(frame);
    [imind,cm] = rgb2ind(im,256);
    outfile = 'BIO.gif';
    % On the first loop, create the file. In subsequent loops, append.
    if i==1
        imwrite(imind,cm,outfile,'gif','DelayTime',0,'loopcount',inf);
    else
        imwrite(imind,cm,outfile,'gif','DelayTime',0,'writemode','append');
    end
    % Clearing the title for every last frame except for the last one
    if 146~=i
        title(ax1,'');
    end
end
clear('ax1','ax2','clims','i','j','lambda','M4','R4','A4','figure4','i1');

Hope this helps!

What is img(j)? How is that a color or black and white image? It should be a filename string.
