Hi adam
This is how i generated Multiple page pdf
I have stored the product details in array aryPrdCode,aryPrdName,aryPrdImageData which i want to draw on pdf
Rest follow the comments..
Happy coding
maybe this error generated coz it din't find the font......if any one can suggest

}maybe this error generated coz it din't find the font......if any one can suggest
