            Bug ID: 125153
           Summary: StarViewMetafile import regression
           Product: LibreOffice
           Version: 6.2.0.3 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: michael.stahl at cib.de

Description:
there is another performance problem though, which is *not* an infinite loop
but at least in a debug build it's taking a bloody long time scaling a bitmap
inside a metafile that must be somewhere in the document to a width of 865
million pixels; this is due to these values read from the metafile:

MetaBmpExScaleAction::Read()

p maPt
$43 = Point = {
  x = 621353314,
  y = -1397620223
}
p maSz
$44 = Size = {
  width = 1917665794,
  height = 242
}

this happens while creating preview image in
SfxPickListImpl::AddDocumentToPickList() during load.
