Hi, I'm following the directions of the livedocs to create a watermark for my images:
The watermark is coming out at the top left corner because the coordinates of the watermark image are set to 0,0. My question is, How do I set it so that the watermark comes out on the bottom center of the image? do i dynamically calculate that or is there a way to do it?

Thanks

Thanks Jayesh that worked. what I did was I got the W and H and subtracted for the hight and width of the watermark image, here's the code:

<cfset alignH =#myImage.height#-120> <cfset alignW =#myImage.width# / 2 - 150>
<cfset ImagePaste(myImage,myImage2,#alignW#,#alignH#)>

Well..I think if you do it ImageRotate way...you have to rotate both the Images. I havent tried it but should work.

May be also you can use ImageGetwidth/imageGetheight functions to find out the dimensions of both the images and calculate the coordiantes.

Rotate the image 180 degrees then add the watermark to the top upside down, then rotate it 180 degrees again.
