Detailed Description

For U_EMR[POLY]EXTTEXTOUT[A|W] emrtext field.

EMF manual 2.2.5, Microsoft name: EmrText Object

Differs from implementation in Mingw and Wine in that the core struct has a fixed size. Optional and movable components must be handled with offsets. Following invariant core there may/must be:

U_RECTL rcl; (Optional, absent when fOptions & U_ETO_NO_RECT) grayed/clipping/opaque rectangle

U_OFFDX offDx; (required) but position isn't static. Offset in bytes to the character spacing array measured from the start of the RECORD, NOT from the start of this structure.

The order of the next two may be reversed, they are found from their offsets.

char string (required) String buffer holding nChars (padded to a multiple of 4 bytes in length).

uint32_t Dx[1] (required) character spacing, array with one entry per glyph.
