pythonによるScreenをキャプチャし、pptxに貼付けする際の最適な方法について
reportによってpptxに貼付ける際、思うように貼付けることができません。（大体は小さめに貼付されます。）何か最適な方法はありますでしょうか。 具体的には、CaptureVideoTool Classのtop,bottom値の考え方,width,heightの値の意味について、ご教示お願い致します。 また、プレースホルダの順序について、screenキャプチャが最前面にきてしまうのは変更することは可能でしょうか。（テキストの方が必ず後ろになってしまいます。） 以上、何卒よろしくお願いいたします。

panopticon 슬라이더 및 다중 인풋 입력 문제 보고
안녕하세요, 몇달 전 판옵티콘 대시보드에 대해 문의드린 적이 있습니다 이후 2025.0.1과 최근 업데이트된 2025.1.1 로 업데이트 후 재시도하였으나 1,2번 문제는 여전히 지속되고 있습니다 1) 대시보드에 액션 슬라이더와 액션 텍스트 박스를 같이 넣었을 때, 텍스트 박스에 직접 숫자를 입력하는 방식은 결과출력에 전혀 문제가 없습니다. 하지만 슬라이더 사용시, 아웃풋 항목들이 간헐적으로 사라지는 경우가 발생됩니다. 동시에 액션 텍스트 박스 값이 슬라이더 이동에 따라 변경되는데 이 값에 소수점이 굉장히 많이 표시됩니다. 이게 원인인지는 모르겠지만 사용자 경험면에서도 좋지…
