GetFTextHeightEx

Syntax:

double pdfGetFTextHeightEx(

const PPDF* IPDF,

// Instance pointer

double Width,

// Width of output rectangle

TTextAlign Align,

// Base text alignment

const char* AText) // Formatted text

The function measures the height of a formatted text block. The function works in the same way as

GetFTextHeight() but the output rectangle must not be set manually beforehand.

The height of the output rectangle is set to -1 to avoid a page break during measuring.

The parameter AText must contain the same text (incl. format tags if any) as which should be

printed later with WriteFText().

Remarks:

This function is implemented in an Ansi and Unicode compatible version.

Return values:

If the function succeeds the return value is the height of the formatted text block. If the function fails

the return value is a negative error code.

GetFullyQualifiedFieldName

SI32 pdfGetFullyQualifiedFieldName(

const PPDF* IPDF, // Instance pointer

UI32 Handle,

// Field handle

UI16* ADDR Value) // Address of a UI16* variable

The function returns the fully qualified name of a field. Note that children of a radio button, for

example, have no name by its own. The export value must be compared to distinguish the children

fields in this case.

Return values:

If the function succeeds the return value is the name length in characters. If the function fails, the

return value is a negative error code.

GetGlyphIndex

Syntax:

SI32 pdfGetGlyphIndex(

const PPDF* IPDF, // Instance pointer

UI32 Index)

// Code page, Unicode, or CJK index

The function returns the glyph index of the given code page or Unicode index. How Index must be

defined depends on the code page with which the font was loaded. For example, if the font was
