When I call SetOrigin(), what is the scope of the change - am I changing the origin for the current stream, the current page, or the entire document?
Thanks, Chris |

Hi,
the reference guide says: "Sets the origin for all subsequent drawing operations." Beware: There is nothing written about pages. Setorigin has no effects for content, which is made before this setting, independed how did make it. It gives QP only an advise, how are coordinates in following function calls to be interpreted. And so it is valid over page boundaries, until you set the origin new. In the background has QP much more to do. If you are interested to understand what, look at "4.2.3 Transformation Matrices" in Adobes PDF-Spec. Werner Edited by edvoigt - 14 Apr 12 at 4:52PM |
