Subject: image scaling problem in khtml
X-MARC-Message: https://marc.info/?l=kfm-devel&m=101752561006554

Hi,

The following image isn't rendered correctly with khtml :
(test.png being 256x256 pixels for example)

<TABLE>
<TD WIDTH=3D512 HEIGHT=3D512 VALIGN=3DTOP >
<IMG SRC=3D"test.png" HEIGHT=3D"100%" WIDTH=3D"100%"></IMG>
</TABLE>

The problem is the height attribute of the image. Somehow, khtml won't sc=
ale=20
the height of the image when it's given as a percentage relative to the=20
available height (which is the height of the table cell, 512 in this case=
).=20
I've been going through the code (render_box.cpp & render_image.cpp) for =
a=20
few hours, but couldn't find where the image scaling takes place, and whe=
re=20
the height of the encapsulating element is asked. I'd like to point out t=
hat=20
horizontal image scaling works ok, with the exception that it's possible =
to=20
scale an image horizontally larger than is allowed by the encapsulating t=
able=20
cell (it's possible to scale the image out of the cell).

Dirk ? Lars ? If you could five me a hint where to look for the related c=
ode,=20
I can try and fix this one myself. If not - maybe you can have a look at =
it ?

Thanks in advance,
