When writing font data, tools should always write zero for reserved fields or bits. Implementations should never make assumptions regarding reserved or unassigned values or bits in bit fields, and can ignore them if encountered. Note that some field values that were undefined or reserved in an earlier revision may be assigned meanings in a minor version change. For purposes of compatibility, version numbers that are represented using a single uint16 or uint32 value are treated like a minor version number, and any format changes are compatible extensions. If the minor version is greater than the latest version recognized by the implementation, then the extension fields will be undetectable to the implementation. If an implementation understands a major version number, then it can safely proceed with reading the table. Minor version number changes always imply format changes that are compatible extensions.

Implementations reading tables must include code to check version numbers so that, if and when the format and therefore the version number changes, older implementations will handle newer versions gracefully. When Fixed is indicated as the type for a version field, the possible values should be treated as an enumeration of specific values, rather than as a numeric value capable of representing many potential major and minor versions. For example, the version number of 'maxp' table version 0. Rather, tables with non-zero minor version numbers always specify the literal value of the version number. When a Fixed number is used as a version, the upper 16 bits comprise a major version number, and the lower 16 bits, a minor version. Only certain tables use a Fixed value for version, and only for reasons of backward compatibility. Note that there are five different version number types, each with its own numbering scheme. Most tables have version numbers, and the version number for the entire font is contained in the Table Directory. It must have one to four non-space characters, padded with trailing spaces byte value 0x A space character cannot be followed by a non-space character. When re-interpreted as characters, the Tag value is case sensitive. As a result, a Tag value can be re-interpreted as a four-character sequence, which is conventionally how they are referred to.ДЇormally, however, the value is a byte array. Each byte within the array must have a value in the range 0x20 to 0x7E. To compute the actual value, take the integer and add the fraction.Д®xamples of 2. The following data types are used in the OpenType font file. TTC should only be used for font collection files. Some of this supporting data is used no matter which outline format is used some of the supporting data is specific to either TrueType or PostScript. YouвЂ™ll find the installation packages and the source code on Github, as well as some documentation on DominikвЂ™s blog.Rasterizers use combinations of data from the tables contained in the font to render the TrueType or PostScript glyph outlines.

ItвЂ™s been tested on macOS, Ubuntu 18.04/19.10, Windows 10 as well as Raspberry Pi OS / Raspbian. Ubuntu Mono 20pt on an E-Paper display connected to Raspberry Pi вЂ“ Click to EnlargeДЇontEdit is written in C++17 and relies on the Qt framework. Once youвЂ™ve flashed the board with your program with the embedded font, you can try it out. Options for the export function include MSB and LSB mode, invert all the bits, tab size, and the font array name. Once youвЂ™re done, you can export the font to an array compatible with C/C++, Arduino (using PROGMEM), or MicroPython/Python (list or bytes objects). You can still add more glyphs manually outside of this range. It does have some limitations as it only works with general-purpose fixed-width desktop font and imports font glyphs for characters in the ASCII printable range (32вЂ¦126 or 0x20вЂ¦0x7e). The program allows you to import fonts, edit glyphs, and potentially add your own custom drawings. So Dominik Kapusta decided to write a little tool to simplify the process.

Instead, you may have to prepare the font in an image editor and convert those into code with a script and that can be cumbersome. It works well as long as your system support standard font formats like TrueType or OpenType, but on embedded systems with even fewer resources, it may not be workable due to the size of the font file, and the footprint of the required libraries. Once I had to use a Chinese TTF font in a project were storage was limited, and I managed to reduce the font size with FontForge open-source editor.
