![]() 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. Update: Based on the comments below, I have begun using "imresize" with the "nearest" option. count fwrite(fid,A,precision) count fwrite(fid,A,precision,skip) Description. ![]() 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.jpg’,’JPG’) will save the image data A in a file ‘outname.jpg’ using the JPEG compression format. 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: imwrite (I,'newlena.jpg','Quality',100) I1imread ('newlena.png') As per imwrite documentation ('Quality',100) pair means no compression but I get a psnr around 59. The function IMWRITE allows you to write an image saved in a data matrix to a file with a specified format. 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. It allows matrix manipulations, plotting of functions, implementation of algorithms and creation of user interfaces. imwrite (A,filename) writes image data A to the file specified by filename, inferring the file format from the extension. It was developed by Cleve Molar of the company MathWorks.Inc in the year 1984.It is written in C, C++, Java. I produce a figure using the following code: figure(6),imageplot(P) drawnow It is a high-performance language that is used for technical computing. 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.
