I read RAW image data from a binary file stream. I have to read just
bytes one by one and put them into a matrix of structs of unsigned
chars.
I have to use unsigned chars because their rangs go from 0 to 255. If
I use chars then a value of 129 will be -128 :(
The problem:
infile.get(Imag eDATA[i][j].R);
Reads only chars... Ok, it works fine with chars, but when I access to
the matrix the value is read like char... but i want rang from 0 -
255...
Help meeeeee
The source is something like that:
#include <iostream>
#include <fstream>
#include <ctime>
#include <stdlib.h>
using namespace std;
struct structRGB {
unsigned char R;
unsigned char G;
unsigned char B;
};
structRGB ImageDATA[576][720];
int main(int argc, char *argv[]) {
int i,j;
ifstream infile;
ofstream outfile;
infile.open("im age.raw", ios::binary);
for(i=0; i<576; i++) {
for(j=0; j<720; j++) {
infile.get(Imag eDATA[i][j].R);
infile.get(Imag eDATA[i][j].G);
infile.get(Imag eDATA[i][j].B);
}
}
infile.close();
outfile.open("c opy.raw", ios::binary);
for(i=0; i<576; i++) {
for(j=0; j<720; j++) {
outfile.put(Ima geDATA[i][j].R);
outfile.put(Ima geDATA[i][j].G);
outfile.put(Ima geDATA[i][j].B);
}
}
outfile.close() ;
system("PAUSE") ;
return 0;
} 1 4761

How about
ImageData[i][j].R = infile.get();
istream::get() returns an int, which is plenty.

Hello All:
I have a field in the database that is an Image. I have no idea how the

Hi,
I am trying to read an image from MS Access DB based on the following article:

The article author is using PictureBox for windows application, while I am

This may be the root cause of my problem. For read button, I converted his VB

Hi Community,
I think I can store Binary Data in SQL Server but when I try to retrieve it,
I always only get one byte.
I think I stored my Binary Data in SQL Server in a Colum of Type Image. At
least when I execute the following code, I get some significant network
traffic. When I check the database with query analyzer, I see 4 Hex Chars in
the image colum. Like 0xe0 etc.

I have been tasked to read some image data from an sql database and
save the files to flat files. OK, sounds easy as I'v used BLOBs
before. But this is an old database and I cannot get the image to
work.
The columns in the database are of type text. Here is one of the

In this article I will provide you an approach to manipulate an image file. This article gives you an insight into some tricks in java so that you can conceal sensitive information inside an image, hide your complete image as text ,search for a particular image inside a directory, minimize the size of the image. However this is not a new concept, there is a concept called Steganography which enables to conceal your secret...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
