Font Convert Tool

Font conversion tool features: Obtain the Unicode code corresponding to all characters to be converted from the standard internal code table (codepage file), custom Unicode code table (or supplementary code table .txt file, custom .cst file), and find the vector font data corresponding to characters according to the Unicode code from the font file (such as .ttf). Convert to a bitmap, and the output is a .bin file.

Font Bin Generation

Please refer to the following steps for how to generate files:

1. Copy the Font library file to the directory \Font Convert Tool\font.

2. Please refer to the documentation under the directory \Font Convert Tool\doc for the specific meanings of each parameter to configure font parameters by editing FontConfig.json.

3. Please open setting.ini and modify the optional configuration items.

4. Double-click fontDirctionary.exe and the font bin will be generated.

FontConfig.json Parameter Description

FontConfig.json parameter description

Field name	Field meaning
codePages	A list of selected characters arranged in a specific order for the text of a language. Multiple sets can be configured.
cstPaths	Binary Unicode code point CST file path. Multiple paths can be set.
customerVals	User-defined continuous Unicode characters. Multiple groups can be set.
firstVal	The starting value of a custom continuous Unicode character.
range	A custom number of consecutive Unicode character.
mappingPaths	User-defined Unicode character set file path. Multiple groups can be set.
fontSet	Used to specify font-related settings to be converted.
bold	Specifies whether converted characters are bolded.
italic	Specifies whether the converted characters are slanted.
scanMode	Specifies how the converted character data is saved. If the value is “H”, the fonts are saved by row; if the value is “V”, the fonts are saved by column.
fontSize	Specifies the converted character size.
font	Specifies the font file to use for the conversion.
renderMode	Specifies how many bits are used to represent a pixel in the converted character bitmap. Supports 1/2/4/8.
indexMethod	Specifies the index mode of the re-index area of the output bin file after conversion, and fills the address index with 0; offset index 1. When the number of characters exceeds 100, it is recommended to choose index mode 0.
crop	Compresses font file size. Always on is recommended. Currently only crop with IndexMethod=0 is supported.

Setting.ini Parameter Description

Setting.ini parameter description

gamma	1	The gamma value is a parameter used to describe the nonlinear relationship between input pixel values and output brightness. The higher the value, the higher the text brightness.
rotate	0	Font Rotation Angle. 0: No rotation. 1: Rotate 90° clockwise. 2: Rotate 90° counterclockwise.
