king.oslo Posted November 10, 2009 Share Posted November 10, 2009 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 Posted November 10, 2009 Share Posted November 10, 2009 $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.
