`pdfScaleCoords`

Concatenate a scale transform (independent X/Y factors, pivot

BOOL32 __stdcall pdfScaleCoords(PPDF IPDF, double sx, double sy);

Delphi

function pdfScaleCoords(const IPDF: PPDF; sx, sy: Double): LongBool; stdcall;

Purpose. Concatenate a scale transform (independent X/Y factors, pivot fixed at the current coordinate origin) onto the current transform.

Description. Applies [sx 0 0 sy 0 0] via the same cm-emit pattern. Unlike pdfRotateCoords/pdfSkewCoords, there is no pivot-point parameter — scaling is always relative to (0,0) in the current coordinate system; to scale about an arbitrary pivot, a caller must bracket this call with translations (or use pdfSetMatrix with a precomputed matrix).

Parameters.

Parameter	Description
`IPDF`	Document handle.
`sx`, `sy`	Scale factors along X and Y; `1.0` = no change, negative values mirror that axis.

Return value. True on success; False if there is no current content stream.
