H / V点上限为预缩放值32768

Question

The Point H/V properties from a given Path in a PDF seem capped at value of 32768 pre-scaling from a matrix transform. I'm trying to read the Point information for certain PDF's where it seems to be limiting the Point data incorrectly. When I try transforming the point using transform matrix for the associated element, the matrix appears to be applied to the capped value rather than the true underlying value. A given point as a reported by the library might have an H or V value greater than 32768 where the scaling value might be something like 0.006.

Is there a way to access a Point with a H or V value greater than 32768 before it is scaled? Or even getting the correct scaled value would be okay.

I've seeing this behavior in version 15.0.4PlusP4k and other 15.0.4.x versions.

Answer 1

Yes, there is are two interfaces to access the points in a path. PDEPathGetData returns a list of ASFixed values, and hence is limited to the ASFixed range (as you found). PDEPathGetDataEx (PDEPath path, ASReal *Data, int DataLen) will return the same array of Points, but they will not be limited to the ASFixed range.

Also, I should point out that Datalogics Support is always available to answer these types of questions from customers. Both on-line, and by Phone.
