Hi Appeon Team,
I'm using PowerBuilder 2022 R3 3391 Build,

we are following this below approach to parallelly converting multiple PSR files into individual PDFs files(i.e. 100 pdf files  created out of 200 psr’s) :

Problem:

In the PSR files, we have a computed column where we set a .bmp image (logo) by passing its file path as the column expression. However, when we process multiple PSR files (around 20 or more), suppose if we process 100 psr's then around 4 to 5 of the generated PDFs have problems such as

  • The image appears broken
  • The colors look incorrect
  • Sometimes the image is not shown at all


the column we use in the PSR:


"compute(name=logo visible="1" band=detail font.charset="0" font.face="Arial" font.family="2" font.height="-8" font.pitch="2" font.weight="400" background.mode="2" background.color="1073741824" color="33554432" x="2432" y="3488" height="232" width="754" format="[GENERAL]" expression="bitmap(~"C:~\Program Files (x86)~\Smart~\Ins~\Temp~\logo.bmp~")" alignment="0" border="0" crosstab.repeat=no )"


Please Find below images:

 Is there a fix or workaround there to prevent bitmap image corruption during batch conversion of PSRs to PDFs?
