Hi,

does anyone know if it is possible to have other dimensions or formats of the image file that is uploaded into the camera for the image overlay? the 128x128 pixels with max. 16 KByte Size and a 256 color bmp format is so incredible poor ...

the other question is, if it is possible to rotate different images with some http comands?
maybe there are firmware hacks aviable for this "problem" ?

for example i do this with the custom text line 1 and the channel title of the camera for rotating my weatherdata into the cameras stream(i user a raspberry pi with a script, to do time based):

wget -qO- "http://user:password@IP-of-the-camera/cgi-bin/configManager.cgi?action=setConfig&VideoWidget[0].CustomTitle[1].Text=YouRTextGoesHere"

wget -qO- "http://user:password@IP-of-the-camera/cgi-bin/configManager.cgi?action=setConfig&ChannelTitle[0].Name=YourTextGoesHere"

now the only problem left is to tweak something with the overlay image.

has anbody an idea, how to relize that?

Have a nice day
Dirk
