[SOLVED] About imagecopyresampled()

[king.oslo]

Hello,

 

I am looking to use this function to resize parts of an image to a fixed thumbnail size. I have used this functions many times, but I am trying to become more advanced as time pass by.

 

I have been looking on the web, however, I cannot find out what these four arguments control. I was hoping somebody knows.

 

I was hoping someone could give me an answer:

 

$src_x

x-coordinate of source point.

 

$src_y

y-coordinate of source point.

 

$dst_w

Destination width.

 

$dst_h

Destination height.

 

[MadTechie]

$src_x & $src_y are the X & Y position of the source image

X = from the left

Y = from the top

 

now just say you have 2 images, and I wish to put image S on top of image D, these allow me to say where the top left of image S start..

ie

image D has a height of 500 and width of 500

image S has a height of 100 and width of 400

and i want Image S to be in the middle of image D, I would set the $src_x to 50 and  $src_y to 200

((500-400)/2) = 50

((500-100)/2) = 200

 

Now just say Image D was 500x500, but image $dst_w and $dst_h, just resize to to whatever size

 

Hope that makes sense!

Doesn't make sense yet, but after breakfast I will look at it again, and I am certain you have provided enough constructive information for me to find out.

 

Topic solved.

 

Thank you,

Kind regards,
