I have used this code many dozen times. . .

And everything worked fine. . .

Perhaps the print driver is damaged. . .

I use "AutoCAD PDF (High Quality Print).pc3"

To John is this backwards ?

"C is a low level language so if you know C you can usually use/learn a higher level language like Lisp, VB(A), etc fairly easily."

Like lisp 4 lines of code C is like 10 lines of code.

Backwards in what sense?

Languages such as LISP/VBA are considered high level because many operations are abstracted away and instead performed by the interpreter/compiler; consequently, programs may be written far more succinctly using relatively readable 'natural' language rather than machine code, generally at the sacrifice of power and performance; whereas low level languages (such as Assembly) are 'closer to the metal', and consequently written in language more readable to a machine than a human, with far fewer operations abstracted, consequently requiring significantly more code to perform the same operation as a high-level language (in which the equivalent machine code is implemented through the design of the language itself, rather than the programmer).

Normally the VovKa code
works perfectly !

But today . . .

What happens ?

Have you tried giving the layer the points are on a color of 255,255,255? Then you could have 3 point styles to control the color of the tree symbol.

Not positive it would work, just thinking out loud.

Thanks for that. Unfortunately, my tree symbology relies on layer transparency to display correctly, so I can't turn that off. Lately, my work around has been to create a duplicate set of points to drive the labeling separate from the symbology. Far from ideal, but at least it works.
