Hello,

I try to read the attached picture with imread and to put the RGB values into the variable M

M = imread('test1.bmp');

but I get the following error:

Reference to non-existent field 'AlphaMask'.
Error in readbmpdata>bmpReadData32 (line 285)
    rgbaMaskArray = [info.RedMask, info.GreenMask, info.BlueMask,
    info.AlphaMask];
Error in readbmpdata (line 32)
                X = bmpReadData32(info);
Error in readbmp (line 17)
X = readbmpdata(info);
Error in imread (line 415)
    [X, map] = feval(fmt_s.read, filename, extraArgs{:});
