imwrite Function in MATLAB

I want to get multiple images from different axes and append them in a single image through imwrite function. The code is:

A=getimage(gca);

[File_Name, File_Path] = uiputfile('*.bmp', 'Save As');

imwrite(A,File_Name,'bmp','WriteMode','append');

I get this Error:

Error using ==> imagesci\private\writebmp Too many input arguments.

it works when i don't mention the writemode. but i want to append the next image so i wanted to use this parameter. Any help would be appreciable, thanks in advance.

'WriteMode' append doesn't appear to work for *.bmp files.

Try writing to a tif/gif/png file.

Okay, i got it. But now i got errors for:

GIF: RGB output not supported.

TIFF and HDF: invalid Colormaps

is there some other function through which multiple images be appended and saved?

What exact code are you using?

[Image Analyst]

What if you stitch them together before writing

tallImage = [topImage; bottomImage]; % One atop the other.
wideImage = [leftImage, rightImage]; % side by side.

repeat as many times as needed to get all the images stitched.

@Sean

I was using the code i mentioned in the question. Changed a little.

@Image Analyst

Okay done with the stitching. Thank you so much!
