InvertPdfBitmap - PDFiumPas

렌더링된 32비트 TBitmap 의 RGB 채널을 제자리에서 반전해 다크 모드나 고대비 보기에 사용합니다

Syntax

procedure InvertPdfBitmap(Bitmap: TBitmap);

Bitmap TBitmap

The helper forces pf32bit and updates ScanLine pixels directly, so it works after RenderPage or ToBitmap without an extra staging buffer

Use these helpers before displaying, saving, or exporting the rendered bitmap when the reader needs a low-vision colour mode

This is a pure helper and does not require an active component instance
API names, type names, and PDF terms keep their original spelling so code search remains reliable

Bitmap := Pdf1.RenderPage(0, 0, Width, Height);
InvertPdfBitmap(Bitmap);
