Update: Based on the comments below, I have begun using "imresize" with the "nearest" option. Any advice? Perhaps it has something to do with the imageplot command? I cannot seem to get that to work in imwrite. How would I program that? I assumed that imwrite() would just write the image directly, but apparently I'm doing something wrong. If, however, I utilize the save function in the open figure (image #1) and save it manually, I get exactly what I want, which is that exact image stored on my computer. imwrite (img, './ccc.bmp' ), datagetframe (figure ( 1 )) imwrite (data.cdata, './ddd.bmp' ) figurefigure imwrite (h2.CData, './fff.bmp') img figure ( 2) h3imshow (img, 'border', 'tight' ) figure fgetframe (figure ( 2 )) imwrite (f.cdata, './ggg.

It's weird as when I run the same code in MATLAB desktop, everything works fine. I then save this image to my computer using the following commands: imwrite(P, 'images/plot.png') Īnd the resulting image is tiny, and missing some of the color information: I'm trying to save a plot as a jpg using imwrite in MATLAB cloud, but the following error occurs: Error using imwrite Unable to open file '/MATLAB Drive\imagesd1w0.05l0.1N40/img1.png' for writing. I produce a figure using the following code: figure(6),imageplot(P) drawnow For example, IMWRITE(A,’outimg. For example, IMWRITE(A,’outimg.jpg’,’JPG’) will save the image data A in a file ‘outname.jpg’ using the JPEG compression format. I have not been able to find any answers to this, either on StackOverflow or elsewhere. The function IMWRITE allows you to write an image saved in a data matrix to a file with a specified format. imwrite(X,map,filename,fmt)writes the indexed image in Xand its associated colormap mapto filenamein the format specified by fmt. The function IMWRITE allows you to write an image saved in a data matrix to a file with a specified format. I'm very new to Matlab, though I know a few other programming languages, so please forgive me if this is something simple.
