📖 NAME

Font::TTF::EBLC - Embedded Bitmap Location Table

🚀 Quick Reference

Use Case	Command	Description
📂 Read EBLC data from a font file	$t->read	Reads the location information of embedded bitmap from the TTF file into memory
💾 Output EBLC data	$t->out($fh)	Outputs the location information of embedded bitmap for this font to a filehandle
🔍 Access bitmap size table	$t->{'bitmapSizeTable'}	Array of tables containing metrics like ppem, bitDepth, flags, etc.
🔍 Access index subtable array	$t->{'indexSubTableArray'}	Array of range information (read-only)
🔍 Access index subtables	$t->{'indexSubTable'}	Array of offsets to EBDT data (read-only)

📝 DESCRIPTION

Contains the sizes and glyph ranges of bitmaps, and the offsets to glyph bitmap data in indexSubTables for EBDT.

Possibly contains glyph metrics information.

📦 INSTANCE VARIABLES

The information specified (R)ead only is read only, those are calculated from EBDT, when it is update-ed.

bitmapSizeTable

An array of tables of following information:

• 📏 indexSubTableArrayOffset (R)
• 📏 indexTablesSize (R)
• 🔢 numberOfIndexSubTables (R)
• 🎨 colorRef
• ↔️ hori
• ↕️ vert
• 🔢 startGlyphIndex (R)
• 🔢 endGlyphIndex (R)
• 📐 ppemX
• 📐 ppemY
• 🖥️ bitDepth
• 🏷️ flags

indexSubTableArray (R)

An array which contains range information.

indexSubTable (R)

An array which contains offsets of EBDT table.

🔧 METHODS

$t->read

Reads the location information of embedded bitmap from the TTF file into memory.

$t->out($fh)

Outputs the location information of embedded bitmap for this font.

🐛 BUGS

Only indexFormat == 1 is implemented. XML output is not supported (yet).
