For an application that displays pictures of articles, we use ComponentOne Vsview.ocx to print.
Initially, the pictures where of BMP format, we thought the application might become quicker if we converted the pictures to JPG format.
The strange thing is that although the JPG files are 10 times smaller than the BMP files, it takes twice as long for Vsview to display them…
We get the handle to the JPG image by using another OCX that only does this:
Public Function LoadImage(ByVal PicName As String) As Picture
Set LoadImage = LoadPicture(PicName)
End Function
This is not slowing things down, the problem seems to be inside Vsview.
Does anyone have experience with this phenomenon?
