![]() ![]() This scales the image properly, but the resulting image is still curiously darker (and therefore has less information) than if I hit the "save" button in the figure. imwrite(X,map,filename,fmt)writes the indexed image in Xand its associated colormap mapto filenamein the format specified by fmt. Update: Based on the comments below, I have begun using "imresize" with the "nearest" option. 1 Answer Sorted by: 2 You must specify the BitDepth option when saving JPEG images with more than 8-bits: note that 16-bit only accepts grayscale images img imread peppers. 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. For example, IMWRITE(A,’outimg. ![]() 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: The function IMWRITE allows you to write an image saved in a data matrix to a file with a specified format. I produce a figure using the following code: figure(6),imageplot(P) drawnow I have not been able to find any answers to this, either on StackOverflow or elsewhere. For most formats: If A is of data type uint8, then imwrite outputs 8-bit values. If Xis of class double, the imwritefunction offsets the values in the array before writing, using uint8(X-1). If Xis of class uint8or uint16, imwritewrites the actual values in the array to the file. The bit depth of the output image depends on the data type of A and the file format. imwrite(X,map,filename,fmt)writes the indexed image in Xand its associated colormap mapto filenamein the format specified by fmt. imwrite creates the new file in your current folder. I'm very new to Matlab, though I know a few other programming languages, so please forgive me if this is something simple. imwrite (A,filename) writes image data A to the file specified by filename, inferring the file format from the extension. ![]()
