UIComponent.filters 속성에 필터를 할당하면 화면에 잘 표시되지만 FlexPrintJob을 통해 인쇄 할 때 무시됩니다.FlexPrintJob에서 그래픽 필터를 인쇄하지 않습니다.
DropshadowFilter, BlurFilter, BevelFilter를 시도했습니다. 그들 중 누구도 나타나지 않습니다. 나는 모든 비트 맵 캐싱 모드를 시도했다. 또한 printAsBitmap.
ASDoc for FlexPrintJob에서 예제로 이동해보십시오. 일부 인쇄 된 구성 요소에 필터를 지정하기 만하면됩니다.
어떻게 할 수 있습니까?
나는 첫 번째 파일에 필터를 넣어 :enter code here
