2D
TRANSLATION AND SCALING
AIM:
Program
to implement 2D transformation
ALGORITHM:
·
Declare
the variables and use graphics function
·
Create
an image to implement 2D transformation
·
First
image translation or repositioning is performed
·
Second
image scaling or alter a sign
·
Print
the output 2D image
CODINGS:
#include<stdio.h>
#include<conio.h>
#include<graphics.h>
#include<math.h>

the translate value (tx,ty):\n");

the scale value (sx,sy):\n");

the x value:\n");
for(i=0;i<=2;i++)
scanf("%d",&x[i]);
printf("Enter
the y value:\n");
for(i=0;i<=2;i++)
scanf("%d",&y[i]);
x[3]=x[0];
y[3]=y[0];
for(i=0;i<=2;i++)
line(x[i],y[i],x[i+1],y[i+1]);
printf("1.Translate\n");
printf("2.scaling\n");
printf("3.Exit\n");
printf("Enter
the choice:");
scanf("%d",&c);
switch(c)
{
case
1:
translate();
break;
case 2:
scale();
break;
default:
printf("Invalid
input\n");
break;
}
}
OUTPUT:
Enter the x value:
100
20
30
Enter the y value:
50
80
60
1.
Translate
2.
Scaling
3.
Exit
Enter the choice:1
Enter the translate value(tx,ty):
50
100
Enter
the x value:
100
20
30
Enter the y value:
50
80
60
1.
Translate
2.
Scaling
3.
Exit
Enter the choice:2
Enter the scale value(sx,sy):
2

RESULT:
Thus, the program has been
successfully executed & output is verified.
