I want to display an image from my device. Currently i can read in the image using binblockread of type unit8 and print the image to a fie using fwrite and it displays fine.
However, I would like to display the image in MATLAB first for a user prompt i'm developing. The array is read into MATLAB as an m by 1 array ranging from 0 to 255. I have tried imshow, imagesc, and image. As well as playing with the different parameters but nothing wants to take.
Perhaps someone could help. I have attached the array I am reading into to matlab. THis is the same array i'm using to print to my .gif file.

Looking at that code, Yes, what you are receiving must already be in image file format. If you were to hunt around long enough you could probably find a Java or library that could accept an array of bytes that is the image file data, and which would decode the image file data into the pixel arrays so that you could display them... but it would be easier to write the file and read it with imread()
