NAME

ESetInfoA: Set font and/or glyph metrics. (V47)
ESetInfo: varargs form of ESetInfoA.

SYNOPSIS

error = ESetInfoA(EEngine, tagList)
D0 A0 A1

ULONG ESetInfoA(struct EGlyphEngine *, struct TagItem *);

error = ESetInfo(EEngine, firstTag, ...)

ULONG ESetInfo(struct EGlyphEngine *, Tag, ...);

FUNCTION

This function is similar to bullet.library/SetInfoA() but does not use a (hidden) "BulletBase" variable that may hold the library base of the wrong font engine if not set properly. It uses EEngine->ege_BulletBase as base of the font engine library to be called.

This function accepts a tag list whose tag field elements are valid for specification, and whose associated data fields are used to supply the specified data.

Data that is supplied via an indirect pointer (OT_Indirect is set) to an array or structure is copied from that array or structure into the internal memory of the library. Changes to the data after this call do not affect the engine.

INPUTS

EEngine: the glyph engine acquired via EOpenEngine() or OpenOutlineFont().
tagList: a tag list containing OT_ tags valid for specification paired with the specification data.

RESULT

This function returns a zero success indication, or a non-zero error code.

NOTES

The function may return with a non-zero error code before it has parsed the whole tag list.

EXAMPLE

// Get Euro glyph with 16 points height
if (!(error = ESetInfo(EEngine, OT_PointHeight, 0x00100000,

OT_GlyphCode, 0x20AC, TAG_END)))

{

if (!(error = EObtainInfo(EEngine, OT_GlyphMap, &glyph, TAG_END)))
{

...
EReleaseInfo(EEngine, OT_GlyphMap, glyph, TAG_END);

}
