![]() 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. Any advice? Perhaps it has something to do with the imageplot command? I cannot seem to get that to work in imwrite. For ex: Theme Copy imwrite (imDIF,'Image difference. Where A is ur image which u want to save,specify the file name and its format. Its not necessary that image needs to be present in ur folder. 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. For most formats: If A is of data type uint8, then imwrite outputs 8-bit values. The bit depth of the output image depends on the data type of A and the file format. ![]() imwrite creates the new file in your current folder. How would I program that? I assumed that imwrite() would just write the image directly, but apparently I'm doing something wrong. Digital Image Processing Using MATLAB How to Read, Write & Display Images in MATLAB IntellCity 5. imwrite (A,filename,fmt) This is the general format of imwrite. imwrite (A,filename) writes image data A to the file specified by filename, inferring the file format from the extension. 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. 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 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. I'm very new to Matlab, though I know a few other programming languages, so please forgive me if this is something simple.
