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
