Re: [libredwg] Testing LibreDwg - Header Variables.

[Felipe Castro]

Ok, but for that strange behavior maybe there is some memory corruption anywhere, it´s a somehow difficult bug to find.

Thanks

It worked...

Just an observation.

I have a R2000 dwg file. The header variable DIMUNIT is set as 2 in the file using CAD. When I try to find the value of DIMUNIT using LibreDwg with following code

printf("\"DIMUNIT\";\"%d\"\n",dwg->header_vars.DIMUNIT);

it gave me value as -678324552. I tried once again without changing the dwg file and it gave me 1929275832. And I tried again it gave me 521680120. Everytime I check it gives different value. Shouldn't it give a same value every time,whether correct or incorrect.

Sorry, I answered looking at the code in the simplified LIBdwg for LIBREdwg things are a litle bit longer, because BITCODE_H is declared as a Dwg_Object_Ref, so it should be:

dwg->header_vars.TEXTSTYLE->handleref.code

Sorry Didnt work

BITCODE_H is a structure of type Dwg_Handle, which has three fields: code, size, value.

You should access these fields with:

dwg->header_vars.TEXTSTYLE.code

dwg->header_vars.TEXTSTYLE.size

dwg->header_vars.TEXTSTYLE.value

ok?

HI

I am trying to check whether LibreDwg is able to output header variables correctly.

I was able to get values of most header variables for example
printf("\"DIMASO\";\"%d\"\n",dwg->header_vars.DIMASO);

But I am not able to get vaules of varible with BITCODE_H e.g. variable TEXTSTYLE

Can anyone help me with this? I have very basic knowledge of programming.
