I was wondering what those nonsense characters below the maximum were. Update: I've successfully stored the header (P6, 650, 652, and 255)) in their right variables (I know because I tried printing their values and they came out right). I'll worry about that once I can actually read and write the text files.
#BINARY HEADER FOR IPICTURE FORMAT HOW TO#
I'm still not sure how to make this program work so I don't store the 650 in width and 652 in height. The goal of my writePPM function (I haven't done anything for that function yet) is to write the PPM format image to an empty file from the given information returned from my readPPM function. The goal of my readPPM function is to return the pixel data in a one-dimensional array of unsigned chars, plus the width and height of the image. This header includes mandatory and optional information: this second one is only needed for the authentication (STM32MP1 Series) and decryption (STM32MP13x lines ) processes.
#BINARY HEADER FOR IPICTURE FORMAT INSTALL#
Windows users can install the OpenJPEG binaries available on the OpenJPEG. The image is in color so there are three bytes (red, green, blue). Each binary image loaded by the ROM code needs to include a specific STM32 header added on top of the binary data. The Python Imaging Library supports a wide variety of raster file formats. Each category image is 172 pixels wide and 120 pixels tall and consumes. Specifically, the Picture column for each record holds the binary contents of a grainy, low-quality, 16-color bitmap image. At the end of the header is a \n and then the binary pixel data. The Picture column in the Categories table already contains binary data for the various category images. The last field gives the maximum pixel value. The next two fields are the width and height of the image. A media type (also known as a Multipurpose Internet Mail Extensions or MIME type) indicates the nature and format of a document, file, or assortment of bytes.MIME types are defined and standardized in IETFs RFC 6838. The header consists of something like this:

I’m trying to read this PPM format image, which contains an ASCII header followed by binary pixel data. Since the result is a picture, we must convert the original numeric datetime value to a character value using the PUT function. I’m fairly new to C programming and I’ve been trying to figure out how to do this for 6 hours without any success.
