Explain two functions to scale the given image.

 Explain two functions to scale the given image.

              imagecopyresized() function : It is an inbuilt function in PHP which is used to copy a rectangular portion of one image to another image and resize it. dst_image is the destination image, src_image is the source image identifier.

 Syntax: 

imagecopyresized(dst_image, src_image, dst_x, dst_y,src_x, src_y, dst_w,dst_h,src_w, src_h)

 dst_image: It specifies the destination image resource. 

src_image: It specifies the source image resource.

 dst_x: It specifies the x-coordinate of destination pointimagecopyresized() function : It is an inbuilt function in PHP which is used to copy a rectangular portion of one image to another image and resize it. dst_image is the destination image, src_image is the source image identifier. 

Syntax: imagecopyresized(dst_image, src_image, dst_x, dst_y,src_x, src_y, dst_w,dst_h,src_w, src_h) dst_image: It specifies the destination image resource. src_image: It specifies the source image resource. 

dst_x: It specifies the x-coordinate of destination point.

 dst_y: It specifies the y-coordinate of destination point.

 src_x: It specifies the x-coordinate of source point. src_y: It specifies the y-coordinate of source point. dst_w: It specifies the destination width

. dst_h: It specifies the destination height. 

src_w: It specifies the source width

. src_h: It specifies the source height. Example: imagecopyresized($d_image,$s_image,0,0,50,50,200,200,$s_width, $s_height); 

imagecopyresampled() function : It is used to copy a rectangular portion of one image to another image, smoothly interpolating pixel values thatresize an image. 

Syntax: 

imagecopyresampled(dst_image, src_image, dst_x, dst_y,src_x, src_y, dst_w,dst_h,src_w, src_h)imagecopyresized() 

function : It is an inbuilt function in PHP which is used to copy a rectangular portion of one image to another image and resize it. dst_image is the destination image, src_image is the source image identifier.
