jpeg & bmp format viewer

[faraz_majidkhan]

Can Anyone tell me about a software that can show me the jpeg & bmp format files in text form like header info, pixels as RGB values(232,122,63),etc.

Also can someone tell me how to display images of bmp & jpeg formats using Turboc & <graphic.h>.

Try "ASCII Art studio" www.torchsoft.com for your first query.

For 1st, try IrfanView and for Q2, TurboC, let me search the code that I wrote..

The problem is that you cannot go more that VGA (640x480 in 16 colors) or SVGA (320x240 in 256 colors) in DOS version of TC.

You can download BMP format specifications from here

*www.aadipa.be/share/bmpfrmat.doc
Alternate Link: *rapidshare.de/files/16701265/bmpfrmat.doc.html

Also, I found out my code, but it is incomplete in TC (I lost completed copy in HDD crash few years ago ), but I opened/edited BMP images in VB and VC++, it is simple once you know format of BMP file.

Here are C sniplets of my code which may help you.

#define BYTE unsigned char
#define WORD unsigned int
#define DWORD unsigned long

/*STRUCTURE OF BITMAP FILE HEADER*/

/* FILE HEADER */
struct fileheader {
	char bftype[2];
	DWORD bfsize;
	WORD bfreserved1;
	WORD bfreserved2;
	DWORD bfoffbits;
	};

struct bitmapinfoheader {
	DWORD bisize;

	DWORD bixpelspermeter;

	DWORD biclrimportant;
	};


/* PALETTE HEADER*/
struct colortable {
	BYTE rgbblue;
	BYTE rgbgreen;
	BYTE rgbred;
	BYTE rgbreserved;
	};

void displayBMPInfo(FILE *fp) {

	unsigned long size;

	struct fileheader header;
	struct bitmapinfoheader info;
	//struct colortable table;

	/*TO CHECK THE EXISTENCE OF FILE */
	if(fp==NULL) {
		return;
		}

	fseek(fp, 0, SEEK_END);
	size = ftell(fp);
	fseek(fp, 0, SEEK_SET);
	fread(&header, 1, sizeof(header), fp);
	clrscr();

	/* TO CHECK THE SIGNATURE OF THE BITMAP FILE "BM" */
	if(header.bftype[0]!='B' || header.bftype[1]!='M') {
		 return;
		 }

	fread(&info,1,sizeof(info),fp);
	//if required the following BMP header informations can be displayed
	printf("\n\t\t\tBITMAP FILE HEADER");
	printf("\nSIZE= %d", size);
	printf("\nBMPFILE's SIGNATURE= %c",header.bftype[0]);
	printf("%c",header.bftype[1]);

Dear friend,
i appreciatate ur efforts towards helping me
Just for ur info i had completed reading the file in C:
My problem is that i will have to create the MINI project IN VB/VC which should satisfy the follwing:
1> Create, save BMP files,
2>Open close Bmp files
3>Editing file
4>adding basic shapes like circle, rectangle
5>adding text to it


This project will not help my cause as its just to be completed and given
with no gain for me whatsoever
So i wanted readymade codes for it

I would rather spend time in working on my major project FACE RECOGNITION

Can u help????????
Or can u suggest me some websites where i am likely to get the codes??
