[FOP-2927] Windows HiDPI: pixelated preview window

• Type: Bug
• Status: Open
• Priority: Critical
• Resolution: Unresolved
• Affects Version/s: 1.0, 2.4
• Component/s: renderer/awt
• Assignee: Unassigned

Description

If you scale your Windows display (All settings > System > Display) to >100% the AWT-Renderer renders a pixelated view. Please see my attachments.

How to reproduce?

• In Windows (7-10) go to
  All settings > System > Display
  and set e.g. 150% for the "size of text, apps and other items"
• extract the FOP archive
• open a shell in fop-2.4\fop
• run the command: fop.bat examples\fo\basic\fonts.fo -awt
• the opening view is pixelated

How to fix?

Windows-Java returns a pre-scaled Graphics2D object. I guess this Stackoverflow question can help:
https://stackoverflow.com/questions/43057457/jdk-9-high-dpi-disable-for-specific-panel

final Graphics2D g = (Graphics2D) graphics;
final AffineTransform t = g.getTransform();
t.setToScale(1, 1);
g.setTransform(t);

But where is the right place (class) for this fix?

 

Thank you

Eric
