: : Hi Everyone,
: : I need some help.
: : i loaded the bitmap image file without any graphic api and now
: : I am trying to zoom image trough Linear or Neighbor Interpolation
: : and bi linear interpolation.
: : Can anyone help me about this?
: : If you have any source code. Please help me.

: : Thanks& Regards

: I will just write the algo
: let us suppose image in array image[x][y]
: tmpimage[2x][y];
: finalimage[2x][2y];
: for j=0 , j<y , j++
: (
: z=0
: for i=0 , i<x , i++
: (
: tmpimage[z][j] = image[i][j]
: tmpimage[z+1][j] = image[i][j]
: z = z+2
: }
: }
:
: z = 0
:
: for i=0 , i<x , i++
: (
: z = 0
: for j=0 , j<y , j++
: (
: finalimage[i][z] = tmpimage[i][j]
: finalimage[i][z+1] = tmpimage[i][j]
: z = z+2
: }
: )
:
: I think you can just change it to you needs.
: I am have forgotton which interpolation is this but definately zooms
: and image.
:
: Also for the mentioned transformation I think you could just play
: around with the image array
:
Also I think I have seen Linear or Neighbor Interpolation and bi linear interpolation. code in matlab demos or sample or tutorial
just look for it in matlab image tutorial atleast you can get the algorithm
