open binary files

[april]

hi...hope someone can help....
i'm writing a program that needs to open binary files of some images. i've tried file.read, fopen and some other functions. however, i don't know how can i display the opened files on the screen for the user to view. anyone has any advice ?

What image format (.bmp, .jpg, etc...) are the files? You need to know how to interpret the binary data.

dear Michael,
the format is .bin
my friend said there are a few formats for .bin files and i need to know which format it is in order to process it. is this true ?

April,

Unfortunately, I'm not sure that ".bin" tells you a whole lot about what kind of image format that file might contain. I don't recognize that as a standard image file extension. Generally, ".bin" is used simply to say that it contains binary data. Its not an indication of how to interpret the data. You and I can write binary files containing anything and give it a ".bin" extension.

Yes, it is true that you need to know the format in order to interpret the binary data within the file.

Is it some kind of "in-house" format that you may be using?

hi Michael,

i'm actually writing a program that opens binary files which : ( these are all that i know about the binary files ) :

an image is captured and its pixels values are stored into an unsigned int 256*256 buffer.
this buffer is then saved as a binary file.

April,

Is that the size of the image (256 wide X 256 high)?

Do you have an example file that I could look at?

April,

Since you're 12 hours ahead of me, send the file to my work and home. Maybe I can look at it before I go to bed tonight.
