MATLAB: How to convert image (bmp,jpg….) to .bin file

write image to .bin file

I have a colour image and I want convert it to binary such as .bin (without losing color). In C code, I can easly use 'fopen' but it can't work in matlab. Anybody help me please.
Sorry my E is not good.

dao - if you have read the image from file (as a bmp or jpg) using imread, then you can use fopen and fwrite to write the data to a binary file. For example,
 % read the image from file
 myImage = imread('someImage.jpg');
 % open a file to write to
 fid     = fopen('myBin.bin','w+');
 if fid>0
     % write the data to file
     fwrite(fid,myImage,'uint8');
     % close the file
     fclose(fid);
 end
In the above, we read in some image and open a file for writing (using w+ to indicate that we wish to open or create a new file for writing). It is assumed that the data type for the image is uint8 so we use that in our precision field of the fwrite function.
