Hello Markus, grabber operators,

instead of the absolute value for width, a percentage can be given. Then=
 you don't have to worry about the exact value and you can even change the=
 size of the grab without adapting the html code.
Some browsers however seem to do funniy things when height=3D"100%" is giv=
en. So best it to ommit height, in that case the apect ratio will be maint=
ained.
So <img src=3D"aktuell.jpg" width=3D"100%"> should do the job.

73, Rik  ON7YD - OR7T

Onderwerp: LF: Rescaling of grabber images

Dear grabber operators,

some grabber captures sometimes look a bit distorted in the browser (see=
 attached example), which sometimes conceals pixel lines or makes text har=
d to read. This apparently happens because by default, Internet Explorer=
 rescales images without pixel interpolation.

A simple solution would be to leave out the scaling information in the htm=
l code, eg. instead of
 <img src=3D"aktuell.jpg" width=3D"863" height=3D"401">
simply use
 <img src=3D"aktuell.jpg">
Then the image is diplayed at its original size, even is that has changed=
 since the generation of the html code.

Best 73,
Markus (DF6NM)
