Collection of Areas
In this example, the page content is divided into areas. Each area has a location

relative to the top left of the page, a width, a depth and a rotation. Each area’s
contents are specified as an X/Y coordinate relative to the top left of the area. For
simplicity, assume that all data is in points and is in ASFixed format:
"C" Example: Multiple Containers per Page with Rotation
void WritePage (DLPDFDOC *Doc, ASFixed Width, ASFixed Depth,
areadata *AreaData)
{
DLPDFPAGE *Page = dlpdfdoccreatepage (Doc, Width, Depth);
areadata *CurrentArea = AreaData;
while (AreaData)
{
DLPDFCONTENT *Content = dlpdfcontentcreate (Doc);
dlpdcontenttranslate (Content, AreaData->X,
Depth - AreaData->Y);
dlpdfcontentrotate (Content, AreaData->Rotation);
WriteLines (AreaData->UserData, Content);
dlpdfcontenttopage (Content, Page);
AreaData = AreaData->Next;
}
