Вставить PNG изображение через кнопку Userform VBA [дублировать]

Я использую эту функцию (обратите внимание, что функция может быть в отдельном модуле):

Private Sub UserForm_Activate()
With Me.Image1
    .BorderStyle = fmBorderStyleNone
    .PictureSizeMode = fmPictureSizeModeZoom
    .BackStyle = fmBackStyleTransparent
    .Picture = LoadImage("C:\images\MinersBag.png")
End With
end sub


Public Function LoadImagePat(ByVal h$) As IPicture 'si LoadImage ne marche pas , ou ne fait pas la transparance correct :
'code by lepelletier Patrick 28/02/2016

Dim Aff As Boolean
Dim Pic As Shape
With Application
    Aff = .ScreenUpdating
    .ScreenUpdating = False
End With
Set Pic = ActiveSheet.Pictures.Insert(h).ShapeRange(1)
With Pic
    .Copy
    Set LoadImagePat = PastePicture
    .Delete
End With
Set Pic = Nothing
If Aff Then Application.ScreenUpdating = True
End Function

Подпрограмма PastPicture принадлежит Стивену Буллену и здесь находится ( ссылка для прямой загрузки ). В случае ссылки rot, вот копия modPastePicture. Сохраните все это в modPastePicture.bas, затем импортируйте этот файл в редактор VBA.

'* MODULE NAME:     Paste Picture
'* AUTHOR & DATE:   STEPHEN BULLEN, Office Automation Ltd
'*                  15 November 1998
'*
'* CONTACT:         Stephen@oaltd.co.uk

'* DESCRIPTION:     Creates a standard Picture object from whatever is on the clipboard.
'*                  This object can then be assigned to (for example) and Image control
'*                  on a userform.  The PastePicture function takes an optional argument of
'*                  the picture type - xlBitmap or xlPicture.
'*
'*                  The code requires a reference to the "OLE Automation" type library
'*
'*                  he code in this module has been derived from a number of sources
'*                  discovered on MSDN.
'*
'*                  To use it, just copy this module into your project, then you can use:
'*                      Set Image1.Picture = PastePicture(xlPicture)
'*                  to paste a picture of whatever is on the clipboard into a standard image control.
'*
'* PROCEDURES:
'*   PastePicture   The entry point for the routine
'*   CreatePicture  Private function to convert a bitmap or metafile handle to an OLE reference
'*   fnOLEError     Get the error text for an OLE error code

Почему бы не использовать Insert / Picture, который принимает файлы png? Вы все равно можете присвоить ему макрос.

AFAIK только png-файлы поддерживают прозрачные фоны.

Если это для пользовательской формы, я не знаю ничего, что вы можете добавить, что поддерживает прозрачные объекты. Однако ваш фон должен быть статическим, чтобы вы могли его подделать.

Возможно, вы могли бы просто совместить цвет за изображением? Вы можете получить цветовой код из своих свойств формы.

Если это статический фон, но не один цвет, вы можете сделать снимок экрана и закрепить часть, которую вы хотите, в качестве фона для изображения, слой 2 изображения вместе в редакторе фотографий, затем выводятся как bmp, который сглаживает два слоя как один. Есть бесплатные редакторы фотографий, которые могут это сделать.
