TrueType font Support by FreeType Library

[darkliquid]

u r placing CGUITTFace instance as Local variable.
it will purge when constructor is done.
on drawing, CGUITTFont needs "Living" CGUITTFace too.
u have to place CGUITTFace as class variable same as ur CGUITTFont.

thx

I am such a MORON!

Damn, it was so obvious, I can't believe I didn't see it, I should know better than this by now!

Thanks zgock!

Hi,

great work, zgock! I only have one significant problem: AntiAlias only works fine with DirectX8, using DirectX9 or OpenGL results in fuzzy font which is a bit thicker than it's original, but doesn't look AA'd (using irrlicht 0.7.1). Anybody who had the same problems or anybody who figured this problem out already?

Greets,

LaVerne

Thanks, very very useful.

Hi.

I tried to use this in my project, however after debuging I found this module is generating serious memory leaks. Here's what _CrtDumpMemoryLeaks showed:

Object dump complete.

I went into details and removed those leaks by makinf following fixes:

1. In CGUITTGlyph::cache(u32 idx)
The object 'img' is allocated twice, but not deleted. So I added bolded lines:

Code: Select all

Driver->setTextureCreationFlag(video::ETCF_ALWAYS_32_BIT,true);
tex = Driver->addTexture(name,img);
Driver->setTextureCreationFlag(video::ETCF_ALWAYS_32_BIT,flg32);
Driver->setTextureCreationFlag(video::ETCF_ALWAYS_16_BIT,flg16);
delete texd;
[b]img->drop ();[/b]
cached = true;

Code: Select all

sprintf(name,"TTFontGlyph%d_16",idx);
video::IImage *img = Driver->createImageFromData(video::ECF_A1R5G5B5,core::dimension2d<s32>(imgw16,imgh16),texd16);
tex16 = Driver->addTexture(name,img);
Driver->makeColorKeyTexture(tex16,video::SColor(0,0,0,0));
[b]img->drop ();[/b]
delete texd16;

2. CGUITTFace::load() creates and initializes whole TT library. That's not good cause it means only one font face can be load or every next face will create separate library object. You should consider creating library object separately in your program and passing it to CGUITTFace objects.

As I said CGUITTFace::load() creates 'library' object. Also 'face' object is allocated. Booth are never deleted. Simpliest solution will be to create destructor for CGUITTFace.

Code: Select all

class CGUITTFace : public IUnknown
{
public:
  FT_Library library;
  FT_Face face;
  [b]CGUITTFace (): library (0), face (0) {};[/b]
  bool load (const c8* filename);
  [b]~CGUITTFace ();[/b]
};

Code: Select all

[b]CGUITTFace::~CGUITTFace () {
  FT_Done_Face (face);
  FT_Done_FreeType (library);
}[/b]

This should purge all memory leaks.

[NeedHelp]

has anyone compiled this with dev-c++ ?
id like to use this but cant figure out how to use it with my dev-c++ project

[Quall]

edit:

Anyone who uses this should use the 1.9 version of truetype 2. Don't use the new version 10 as it causes errors. I have read that the a cvs version had repaierd the problem though.

[Quibbler]

reply to Guest:
no, not with Dev-c++ but I have tried it with Borland's free compiler and it works fine for me.

I made my own makefile and compiled latest version of FreeType engine (2.1.10)

I highly recommend anyone using latest version because lots of bugfixes have been made.

I have a question though:

Is it possible to change the amount of AntiAlias in some way?
I mean, instead of just setting the AA-flag, you can set a value.
That would be really nice

Is there any way to get this to the .NET side also?

Yes, compiled with no problems in DevC++ with Freetype2 and IrrLichtSDK 1.0.

This is a quite useful add-on to the IrrLicht engine... I'd like to see it built in in the next version

[alguem]

using dev-c++ i got errors:

Code: Select all

using freetype219ST.lib at the linker

[hybrid]

you have to add the files to project such that the object files become compiled and will be linked to the library in the end.

Can someone submit this to the Irrlicht source code?

I'm not sure if this will make it into the Irrlicht core. Additional libraries are always problematic, and FreeType is rather large and complex. But, as said elsewhere, a better support for code contributions might be possible.

It worked here, but as previously mentioned there might be a problem when using winzip.
