## Function Documentation

### int th\_render\_cell\_mac (struct thcell\_t cell, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given cell using Mac Thai glyph set.

**Parameters:**

*cell* : the cell to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
 *is\_decomp\_am* : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

**Returns:**

total number of glyphs written to *res*\[\]

Calculates glyphs from Mac Thai glyph set for the given *cell*, and store the glyph string in *res*, terminated with '\\0'. If resulting glyphs are longer than the provided buffer, only the first *res\_sz* glyphs are stored.

### int th\_render\_cell\_tis (struct thcell\_t cell, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given cell using TIS-620 glyph set.

**Parameters:**

*cell* : the cell to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
 *is\_decomp\_am* : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

**Returns:**

total number of glyphs written to *res*\[\]

Calculates glyphs from TIS-620 glyph set for the given *cell*, and store the glyph string in *res*, terminated with '\\0'. If resulting glyphs are longer than the provided buffer, only the first *res\_sz* glyphs are stored.

### int th\_render\_cell\_win (struct thcell\_t cell, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given cell using Thai Windows glyph set.

**Parameters:**

*cell* : the cell to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
 *is\_decomp\_am* : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

**Returns:**

total number of glyphs written to *res*\[\]

Calculates glyphs from Thai Windows glyph set for the given *cell*, and store the glyph string in *res*, terminated with '\\0'. If resulting glyphs are longer than the provided buffer, only the first *res\_sz* glyphs are stored.

### int th\_render\_text\_mac (const thchar\_t \* s, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given text using Mac Thai glyph set.

**Parameters:**

*s* : the string to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
 *is\_decomp\_am* : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

**Returns:**

total number of glyphs written to *res*\[\]

Calculates glyphs from Mac Thai glyph set for the given string *s*, and store the glyph string in *res*, terminated with '\\0'. If resulting glyphs are longer than the provided buffer, only the first *res\_sz* glyphs are stored.

### int th\_render\_text\_tis (const thchar\_t \* s, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given text using TIS-620 glyph set.

**Parameters:**

*s* : the string to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
 *is\_decomp\_am* : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells

**Returns:**

total number of glyphs written to *res*\[\]

Calculates glyphs from TIS-620 glyph set for the given string *s*, and store the glyph string in *res*, terminated with '\\0'. If resulting glyphs are longer than the provided buffer, only the first *res\_sz* glyphs are stored.

### int th\_render\_text\_win (const thchar\_t \* s, thglyph\_t res\[\], size\_t res\_sz, int is\_decomp\_am)

Render the given text using Thai Windows glyph set.

**Parameters:**

*s* : the string to render \
 *res* : the buffer for storing output glyph string \
 *res\_sz* : the size of *res* buffer \
