ftgl's Issues

Replace FindFTGL.cmake with FTGLConfig.cmake

Since FTGL is creating this file, it can just tell CMake where it lives rather than shipping a file on how to find itself.

NaN values in vectoriser

This here crashes when d[0] or d[1] is NaN which apparently can happen with some characters in some fonts. Not sure why there would be such values.

ftgl/src/FTVectoriser.cpp

Line 321 in 16f7667

gluTessVertex(tobj, const_cast<GLdouble*>(d), (GLvoid *)d);

This is where the segfault happens (inside the glu library):

ftgl/src/FTVectoriser.cpp

Line 326 in 16f7667

gluTessEndPolygon(tobj);

I have implemented a crude fix here:

error undefined reference to `FTExtrudeFont::FTExtrudeFont(char const*)'

while I am compiling my opengl code I am facing this error.how to remove this?

all: sample2D

sample2D: Sample_GL3_2D.cpp glad.c
        g++ -o sample2D Sample_GL3_2D.cpp glad.c -lGL -lglfw -ldl -std=c++11

clean:
        rm sample2D

this is my contents of Makefile
and my code for rendering the font

const char* fontfile = "Monaco.ttf";
GL3Font.font = new FTExtrudeFont(fontfile); // 3D extrude style rendering

if(GL3Font.font->Error())
{
    cout << "Error: Could not load font `" << fontfile << "'" << endl;
    glfwTerminate();
    exit(EXIT_FAILURE);
}

// Create and compile our GLSL program from the font shaders
fontProgramID = LoadShaders( "fontrender.vert", "fontrender.frag" );
GLint fontVertexCoordAttrib, fontVertexNormalAttrib, fontVertexOffsetUniform;
fontVertexCoordAttrib = glGetAttribLocation(fontProgramID, "vertexPosition");
fontVertexNormalAttrib = glGetAttribLocation(fontProgramID, "vertexNormal");
fontVertexOffsetUniform = glGetUniformLocation(fontProgramID, "pen");
GL3Font.fontMatrixID = glGetUniformLocation(fontProgramID, "MVP");
GL3Font.fontColorID = glGetUniformLocation(fontProgramID, "fontColor");

GL3Font.font->ShaderLocations(fontVertexCoordAttrib, fontVertexNormalAttrib, fontVertexOffsetUniform);
GL3Font.font->FaceSize(1);
GL3Font.font->Depth(0);
GL3Font.font->Outset(0, 0);
GL3Font.font->CharMap(ft_encoding_unicode);

Undefined reference to glew

while I am working on rendering fonts using ftgl in my opengl project I am encountering errors stating

looks like the errors is being raised by the libftgl.so library. I have installed the GLEW using the glew packages in the ubuntu. but dont understand why it isn't being referenced.

FTBufferFont clips bitmap fonts wrongly

See test/FTBufferFont-Bitmap.cpp from my pull request. (I created this test program to demonstrate fixing another bug, drawing garbage in this case, but the clipping bug remains.)

Info needed

(Edited after manually looking in the dylib for function names)

Hello,

It seems that the functions from the commit 92d175e are not present in the ftgl 2.1.3 library that was installed by brew install ftgl on my mac.

What should I do to install this version? Is it possible to merge the changes of this fork back to the main repository and make a new release?
