Description khirano 2003-08-25 05:18:31 UTC
Chinese characters overlap glid lines depending on resolution and zoom on
Windows98SE

When using Grid (lines and characters) in Text Grid and the following settings,
http://www.transwift.net/ooo/grid_sample_setting_en.html
only Chinese characters overlap glid lines depending on monitor's resolution and
Writer's zoom on Windows98SE.

A sample .sxw file is here:
http://www.transwift.net/ooo/grid_win98se_kochi.sxw

This only occurs when using Kochi fonts.
Kochi Mincho (kochi-mincho.TTF) is here:
http://www.transwift.net/ooo/kochi-mincho.TTF

Resolution&#65306;1024x768
Zoom&#65306;200% Fine, this is ok.

Sorry but don't use the following settings,
http://www.transwift.net/ooo/grid_sample_setting_en.html
This is for another issue ;->

Use Kochi fonts and simply open the following file.

pl->hdu: could you please have a look ?

It looks like the problem only occurs for glyphs and pixel sizes where embedded 
bitmaps are used. Can you export the document to PDF and attach it? This will get 
rid of embedded bitmaps and also show which font is used for glyph fallback if any.

Hi,

Here is the PDF export of the grid_win98se_kochi.sxw:
http://www.transwift.net/ooo/grid_win98se_kochi.pdf

But the PDF output shows another problem:

Comment 6 hdu@apache.org 2003-12-12 14:37:09 UTC
Looking closer at the problem I think the problem is caused by the combination of:
- Win98's vertical text handling
- Kochi Mincho having vertical alternates for selected glyphs (e.g. Kana)
- Kochi Mincho having embedded bitmaps for selected glyphs at selected sizes (10
to 17, 20 and 21 pixels)

I'm confident the problem is that Win98 runs into problems when a glyph which
both has a vertical alternate outline and an embedded bitmap for horizontal mode
doesn't have a matching vertical alternate for the embedded bitmap
=> not a OOo problem, but a W98+font problem
The problem the user sees is valid, but I'm setting the status of this issue to
invalid, because it is not OOo's problem.

Removing target from invalid Issue, to reduce the statistics.
