Tool for creating Irrlicht bitmap+vector fonts,
|
|
started by Gaz Davidson in December 2006
|
|
|
|
Due to my laziness and Microsoft's unintuitive API, surrogate pairs and
|
|
nonspacing diacritical marks are not supported!
|
|
|
|
Linux bitmap font support added by Neil Burlock Oct 2008
|
|
Note: Xft/Freetype2 is used to render the fonts under X11. Anti-aliasing
|
|
is controlled by the system and cannot be overriden by an application,
|
|
so fonts that are rendered will be aliased or anti-aliased depending
|
|
on the system that they are created on.

L"------------\n\n"
|
|
L"When making bitmap and vector fonts, you should consider the potential legal "
|
|
L"issues with redistributing the fonts with your software; this tool basically "
|
|
L"copies font data and some authors might not like this!\n"
|
|
L"If you purchased fonts or they came with an application or your OS, you'll have"
|
|
L"to check the license to see what restrictions are placed on making derivative works.\n\n"
|
|
L"PD and the OFL\n"
|
|
L"--------------\n\n"
|
|
L"You'll find lots of fonts on the web listed as Public Domain, you can do what you like "
|
|
L"with these.\n"
|
|
L"Many fonts are released under the Open Font License, which is a 'viral' open source "
|
|
L"license like the GPL. It's worth reading the license here: http://scripts.sil.org/OFL\n"
|
|
L"The most important restrictions are- you must include the original font's license, you "
|
|
L"can't stop your users from using or distributing the font, the font must have a "
|
|
L"different name the original.\n\n"
|
|
L"Some free fonts can be found here- www.openfontlibrary.org\n"
|
|
L"http://savannah.nongnu.org/projects/freefont/";
|
|
|
|
const wchar_t *helptext = L"This tool creates bitmap fonts for the Irrlicht Engine\n\n"
|
|
|
|
L"First select a character encoding from the list, then choose the font, "
|
|
L"size, and whether you'd like bold, italic, antialiasing and an alpha channel. "
|
|
L"In Windows, antialiasing will be ignored for small fonts\n\n"
|
|
|
|
L"Then select a texture width and height. If the output exceeds this then more than "
|
|
L"one image will be created. You can use the scrollbar at the top of the screen to "
|
|
L"preview them. Most modern graphics cards will support up to 2048x2048, "
|
|
L"keep in mind that more images means worse performance when drawing text!\n\n"
|
|
|
|
L"If you want a vector font rather than a bitmap font, check the vector box. "
|
|
L"Vector fonts are stored in system memory while bitmap fonts are in video ram\n\n"
|
|
|
|
L"Click create to preview your font, this may take lots of time and memory "
|
|
L"when making a font with a lot of characters, please be patient!\n\n"
|
|
|
|
L"Now you're ready to give your font a name, select a format and click save.\n\n"
|
|
L"To load your font in Irrlicht, simply use env->getFont(\"Myfont.xml\");\n\n"
|
|
|
