Hi Roger,
Glad to know that you’ve made such interesting discovery.
I highly doubt that
it’s the gasp
table that is linked to the “Grid Fitting” properties you
posted. You can find the list of tables in the “Font Info” Tab -
“SFNT” Sub-Tab in the ftinspect
tool. The raw data of the gasp
table of SimSum 3.03 is as follows:
The second entry (the
third quadlet) indicates the max PPEM equals to 24 and the flag
is set to GASP_GRIDFIT.
To access the gasp
table programmatically, try the FT_Get_Gasp
function. It provides limited functionality, so maybe you need
to do your own parsing with FT_Get_Sfnt_Table
and FT_Load_Sfnt_Table,
if you want to read the whole table.
Cheers,
chariri
