BMP IMAGE ROTATION WITH C/x86-64 HYBRID PROGRAMMING

ŁUKASZ STANISZEWSKI

I. HOW TO:

• USE LINUX OS!
• ADD .BMP (BLACK-WHITE) IMAGE FILE TO MAIN DIRECTORY
• CHANGE FILE NAME IN project.c FILE:

	int main(int argc, char* argv[])
	{
		imgInfo* pInfo;
		if (sizeof(bmpHdr) != 62)
		{
			printf("Change compilation options so as bmpHdr struct size is 62 bytes.\n");
			return 1;
		}
		if((pInfo = readBMP("eiti.bmp"))!=0)			// <---- HERE
		{
			allocate_for_output(pInfo);								
			change_headder(pInfo);
			...

• THROUGH SYSTEM CONSOLE CHANGE DIRECTORY TO PROJECT'S DIR AND TYPE:

make all

• NEXT TYPE IN CONSOLE:

./program

• RESULT IMAGE IS IN result.bmp FILE
