I am still working on FreeType for D, and I am having trouble, of course.

Sooo, if FreeType is in C, and I am writing a binding... And there is an enum in the headers, which is refered to by the name of the enumeration...

I should take this...

/* C Code */
typedef enum FT_Glyph_Format_
{
	FT_GLYPH_FORMAT_NONE = 0,
	FT_GLYPH_FORMAT_COMPOSITE = 1668246896,
	FT_GLYPH_FORMAT_BITMAP = 1651078259,
	FT_GLYPH_FORMAT_OUTLINE = 1869968492,
	FT_GLYPH_FORMAT_PLOTTER = 1886154612
} FT_Glyph_Format;
/* */

and write this?

/* D Code */
alias int FT_Glyph_Format;
const int FT_GLYPH_FORMAT_NONE = 0;
const int FT_GLYPH_FORMAT_COMPOSITE = 1668246896;
const int FT_GLYPH_FORMAT_BITMAP = 1651078259;
const int FT_GLYPH_FORMAT_OUTLINE = 1869968492;
const int FT_GLYPH_FORMAT_PLOTTER = 1886154612;
/* */

The reason I am asking, is because I am getting an error that the FT_Glyph_Format is invalid, which to me hints wrong data type, but I have tried everything I feel like...

How big is a C enumeration in D? Am I doing this all wrong? ANY Help would be really great!

I would personally just do this:

enum FT_Glyph_Format
{
    FT_GLYPH_FORMAT_NONE = 0,
    FT_GLYPH_FORMAT_COMPOSITE = 1668246896,
    FT_GLYPH_FORMAT_BITMAP = 1651078259,
    FT_GLYPH_FORMAT_OUTLINE = 1869968492,
    FT_GLYPH_FORMAT_PLOTTER = 1886154612
}

But you could do this:

alias int FT_Glyph_Format;
const FT_Glyph_Format FT_GLYPH_FORMAT_NONE = 0;
const FT_Glyph_Format FT_GLYPH_FORMAT_COMPOSITE = 1668246896;
const FT_Glyph_Format FT_GLYPH_FORMAT_BITMAP = 1651078259;
const FT_Glyph_Format FT_GLYPH_FORMAT_OUTLINE = 1869968492;
const FT_Glyph_Format FT_GLYPH_FORMAT_PLOTTER = 1886154612;

An enum will be, afaik, an int by default.

How about this?

    enum FT_Glyph_Format {
        NONE      = 0,
        COMPOSITE = 1668246896,
        BITMAP    = 1651078259,
        OUTLINE   = 1869968492,
        PLOTTER   = 1886154612
    }

No point forcing yourself to write such redundancies as FT_Glyph_Format.FT_GLYPH_FORMAT_COMPOSITE all the time.  This way, the final underscore effectively turns into a dot.  This is how, in SDWF, I create enums from Windows API constants.
