推荐答案
请勿使用.ExportAsFixedFormat。而是在每个幻灯片上使用.SaveAs或使用.Export方法。
Don't use .ExportAsFixedFormat. Instead, either use .SaveAs or use the .Export method on each slide.
。Export可以提供更多控制权。在VBA中,您会这样:
.Export gives you far more control. In VBA, you'd do like so:
Dim oSl As Slide
Dim lWidthInPixels As Long
Dim lHeightInPixels As Long
lWidthInPixels = 1024
lHeightInPixels = 768
For Each oSl In ActivePresentation.Slides
oSl.Export "c:\path\myfile" & Format(oSl.SlideIndex, "0000") & ".jpg", _
"JPG", _
lWidthInPixels, _
lHeightInPixels
Next
