I have made a function for high level line entity access, Can we have
functions like this for all entities.
Function:-
Dwg_Entity_LINE **
extract_lines(Dwg_Data *dwg)
{
int i,x=0;
Dwg_Entity_LINE ** lines = (Dwg_Entity_LINE **) malloc(
count_data(dwg, "LINE") * (sizeof (Dwg_Entity_LINE*) + 2));
for (i = 0; i < dwg->num_objects; i++)
{
Dwg_Entity_LINE *line;
if(DWG_TYPE_LINE==dwg->object[i].type)
{
lines[x] = dwg->object[i].tio.entity->tio.LINE;
x++;
}
}
return lines;
}
Usage :-
Dwg_Entity_LINE **all_lines;
all_lines = extract_lines(&dwg);
for (i = 0; i < count_data(&dwg,"LINE") ; i++)
{
printf("%f \n",all_lines[i]->start.x);
}
I have created a count_data function that counts different types of
entities according to input to the function
Please check it here [0]. Function was large so I showed here.
example usage is like :-
count_data(&dwg,"LINE")
count_data(&dwg,"ARC")
count_data(&dwg,"LAYER")
count_data(&dwg,"LAYER_CONTROL")
count_data(&dwg,"BLOCK_CONTROL")
