Welcome to 71 Squared! A UK based indie company making innovative Mac apps and renowned for it's #1 particle design and bitmap font editing tools.

There are three types of font assets available to games made with Cocos Creator: system fonts, dynamic fonts, and bitmap fonts. The system font renders text by calling the system font that comes with the game running platform, and does not require the user to add any related assets to the project.
I have a question concerning Bitmap fonts. I need to create fonts for screen device. It should consists of bitmaps of all printable characters. To get a bitmaps of all characters I am using the fol.
Coco is a 2017 American fantasy adventure film produced by Pixar Animation Studios and released by Walt Disney Pictures. The story follows a 12-year-old boy named Miguel who sets off a chain of events relating to a century-old mystery, leading to an extraordinary family reunion.

This program will allow you to generate bitmap fonts from TrueType fonts. The application generates both image files and character descriptions that can be read by a game for easy rendering of fonts.

The program is freeware and open source, but a donation is greatly appreciated.

If you don't have an image viewer capable of reading TGA, PNG, or DDS files, I recommend PUPP, another free product from AngelCode.

Features

Support for complete Unicode 13.0 character set, as well as 8 bit OEM character sets
Optimal use of texture space, i.e. as little unused area as possible
Support for kerning pairs
Easy to use file format, either normal text file or xml files. Binary format is available for those that prefer that
8bit or 32bit texture output (TGA, PNG, and DDS files)
Option for packing 4 layers of font images into 1 32bit texture. Needs special shader to render with, but saves a lot of memory
Anti-aliasing, both through Windows native font smoothing and super sampling
Configurable padding and spacing between characters
Select characters from text file, supports both UTF8 and UTF16 encoded files
Generate bitmap font from command line
Import colored images as characters, supports: bmp, jpg, tga, dds, png
Optional outline to font characters
Optional packing of characters with outline into 1 channel. Needs special shader to unpack during rendering, but saves a lot of memory
Use TrueType fonts directly from the file without installing them first
Autofit font size for target texture size

Documentation

The manual is included with the tool, but for those who wish to take a look at it without installing the tool first it is also available here. The manual describes bothhow to use the tool and the file format of the generated files.

Source code

The source code is available under the widely known zlib license. The svn repositoryis hosted at SourceForge.net

Get the code by pointing your svn client at: http://svn.code.sf.net/p/bmfont/code/trunk.

If you want any support with the code, then please visit the forums.

Observation on virus alert

Avira anti-virus has been known to give a virus alert when scanning bmfont.exe or the installer. This is a falsepositive generated by their heuristic functions that tries to predict and catch unknown viruses. I've already reportedthis false positive to Avira a few times and each time they recognize it as a false positive, however for some reasonthe problem comes back months later (presumably when they update the heuristic functions).

If anyone has any idea what I need to change in the code to prevent this false alert I would very much like to know.
