FontMgr

[a740g]

This is basically a continuation of some code I posted here.

I originally planned this for an upcoming update to InForm-PE's UiEditor. However, while experimenting with this, it turned out to be nice little 4-function cross-platform library. I am sharing it here hoping it might be useful.

The library has 4 functions:

Code: (Select All)

''' @brief Builds an array of fonts from that are available in the host OS (user installed + system installed).

''' @param fontList This a dynamic string array. The function will redimension fontList starting from 1.

''' @return The count of fonts found.

FUNCTION FontMgr_BuildList~& (fontList() AS STRING)





''' @brief Returns the font name by directly probing a font file.

''' @param filePath This the font file path name.

''' @param fontIndex This is the font index inside a TTC and it is always zero based. Must be 0 for TTF & OTF.

''' @param nameId The component needed from the font's name table

''' @return The name of the font. Invalid filePath or fontIndex will return an empty string.

FUNCTION FontMgr_GetName$ (filePath AS STRING, fontIndex AS _UNSIGNED LONG, nameId AS _UNSIGNED _BYTE)





''' @brief Returns the number of fonts in a collection (TTC).

''' @param filePath This the font file path name.

''' @return 1 or more for valid font files. 0 for invalid font files.

FUNCTION FontMgr_GetCount~& (filePath AS STRING)





''' @brief Probes and returns the supported font size range (useful for bitmap fonts).

''' @param filePath This the font file path name.

''' @param fontIndex This is the font index inside a TTC and it is always zero based. Must be 0 for TTF & OTF.

''' @param outMinSize [OUT] The minimum size supported by the font

''' @param outMaxSize [OUT] The maximum size supported by the font

''' @return True if a valid size range was probed

FUNCTION FontMgr_GetSizeRange%% (filePath AS STRING, fontIndex AS _UNSIGNED LONG, outMinSize AS _UNSIGNED _BYTE, outMaxSize AS _UNSIGNED _BYTE)

Demo output:



Update: Added functionality to read any string from the font name table like family name, style, full name, vendor, designer, copyright etc.
