* LibGDX port of Terrarum Sans Bitmap implementation
|
||
*
|
||
* Filename and Extension for the spritesheet is hard-coded, which are:
|
||
*
|
||
* - ascii_variable.tga
|
||
* - hangul_johab.tga
|
||
* - LatinExtA_variable.tga
|
||
* - LatinExtB_variable.tga
|

* - kana.tga
|
||
* - cjkpunct.tga
|
||
* - wenquanyi.tga.gz
|
||
* - cyrillic_variable.tga
|
||
* - fullwidth_forms.tga
|
||
* - unipunct_variable.tga
|
||
* - greek_variable.tga
|
||
* - thai_variable.tga
|
||
* - puae000-e0ff.tga
|
||
*
|
||
*
|
||
* Glyphs are drawn lazily (calculated on-the-fly, rather than load up all), which is inevitable as we just can't load
|
||
* up 40k+ characters on the machine, which will certainly make loading time painfully long.
|
||
*
|
||
* @param noShadow Self-explanatory
|
||
* @param flipY If you have Y-down coord system implemented on your GDX (e.g. legacy codebase), set this to ```true``` so that the shadow won't be upside-down. For glyph getting upside-down, set ```TextureRegionPack.globalFlipY = true```.
