Element API

void fpg_element_begin(const char*desc);

• Cause opening element definition.
• Must be called before any drawing function is called otherwise the generated footprint would be broken.

void fpg_element_end(void);

• Cause element to close.
• Must be called when footprint generating is done.

void fpg_set_file(FILE *f);

• Set file handle to write footprint to.
• Must be called before any drawing function is called.
• Changing file in the middle of generating footprint would lead to broken fooptrint.
• You must close this file with fclose() after footprint was generated, this is not done automatically.
• Tip: you can pass stdout parameter for footprint to be written to stdout.

void fpg_set_file(FILE *f);

• Get file handle we are writing footprint to.

void fpg_set_units(enum fpg_units units);

• Set units we are working with.
• It's safe to change units while generating footprint.
• For default we are working with pcb default backend format that's mils/100.
• See enum fpg_units;

enum fpg_units fpg_get_units(void);

• Get units we are working with.
• See enum fpg_units;

enum fpg_units;

• fpg_mm milimeters.
• fpg_um micrometers.
• fpg_mil mils
• fpg_pcb pcb backend format mils/100
• Warning: all drawing functions takes integer numbers as parameters, so choose units wisely in order not to create huge rounding errors.
