) 
 

Constructor for installed truetype font gallery item.

Author:

Date:
27/1/95
Parameters:
PreviewFontsToDisplay - A pointer to a kernel bitmap which will be used [INPUTS] by this item on redraws. FontName - Pointer to a description to place alongside the preview in the gallery IL - Internal leading value required by preview generation code - saves passing an entire newtextmetric about lplf - a pointer to a log font structure which corresponds to this item. We need to allocate memory and store the entire structure for each item at the moment so we can generate thumbnails later on. This needs sorting out at some point ! TheID - ID to associate item with... This is only really used for the filenames for saving at present.
