How can I add a watermark to images at the left, not the right

HELLo开发者_运维知识库, i'm using this code and its work very good but it add the logo at the right and iam want in on the left

---

I see these lines:

21     // destination x and y
22     $imageWidth-$logoWidth, $imageHeight-$logoHeight,

That is probably the right (minus the width of the image) bottom (minus the height) point, from where the watermark is started to write.

Try and replace that with for instance this for left top:

21     // destination x and y
22     0 , 0,

Or if you want left bottom, try:

21     // destination x and y
22     0 , $imageHeight-$logoHeight,

In row 22:

0, $imageHeight - $logoHeight,
