status = annot:SetLineAnnotPosition(startpoint, startstyle, endpoint, endstyle)
The startstyle
and endstyle
parameters must be one of the following constants:
#HPDF_LINE_ANNOT_NONE #HPDF_LINE_ANNOT_SQUARE #HPDF_LINE_ANNOT_CIRCLE #HPDF_LINE_ANNOT_DIAMOND #HPDF_LINE_ANNOT_OPENARROW #HPDF_LINE_ANNOT_CLOSEDARROW #HPDF_LINE_ANNOT_BUTT #HPDF_LINE_ANNOT_ROPENARROW #HPDF_LINE_ANNOT_RCLOSEDARROW #HPDF_LINE_ANNOT_SLASH |
The parameters startpoint
and endpoint
must be tables that describe a point each.
Thus, each of those tables must contain the fields x
and y
.
Returns #HPDF_OK
on success. Otherwise, returns an error code and the error handler is invoked.
