HPDF_Page_SetDash

[Finn Arildsen]

Hi

 

I have been using a fairly old version (@2014) of LibHaru, and finally decided to update to the latest.

 

While integrating the latest version, I found that HPDF_Page_SetDash was changed at some point from taking an array of HPDF_REAL to taking an array og HPDT_UINT16 for the dash_ptn parameter.  Also, I realized that there is now a check that none of the elements in the pattern can be zero.

 

I don’t know if someone can explain this change?   It breaks my code – in particular the check for elements of value 0.    Using a pattern with REAL length elements and allowing zero length elements has been working flawlessly for many years.   Using zero length dashes with round line ends renders a dotted line.   This may not be the most elegant approach, but it works.

 

😊

 

Best regards,

Finn

I also have an old version, and the HPDF_Page_SetDash routine I have takes an array of integers. My source dates from 2009, and the configure file references libHaru 2.2.1. Yours might be a *lot* older.

It does look like it would be relatively easy to re-gen a function definition that uses REAL's.

There is one call to HPDF_IToA that builds a successive buffer using the UINT16 values. You could function overload to use REAL to access a different routine with the same name. The compiler should be able to handle that.
