    Hi All,
     
    Does anyone know the format of images on the newer 7945/7965 phones ? We are using the XML tag <CiscoIPPhoneImageFile> to have a image viewer (similar to the SDK sample: PNGViewer).
     
    The Development Notes state: Resolution: 298 x 156, 16 Color Depth (bits), PNG.
     
    Our problem is that we can not figure out how to format the images. It is a different format than the one required for background images. By random trying, we have found one which works, which I am attaching.
     
    How do we have to format PNG images ? What image programs are you using ? Special settings ?

    Any help is highly appreciated,
    Michael

    As far as I know pretty much any .png file close to the right size and color depth will be fine.  PNG being an open standard graphic image format: http://en.wikipedia.org/wiki/Portable_Network_Graphics
     
    If you are having difficulties with specific PNG images, you might try removing special features like transparency, interlacing, animation, etc.
     
    If you have a PNG which think should work but isn't, feel free to attach.

    Thanks David for looking into this.
     
    We have done more testing with some PNG images from the IP Phone XML SDK from Cisco. We are using the ASP code from PNGviewer sample. None of it worked on 7945/65 but it works on the 7970. We are still stuck how to format the PNG so that it displays on 7945/65.
     
    Please find attached the PMG images we used for testing (from the SDK) and I paste here the XML code which seems to work. On the 7945/65 a small icon with a red X appears. Does that mean it is not happy with the format ? BTW, phone loads are default CUCM 7.1.3 (SCCP45.8-5-2SR1S)
     
    Any help is appreciated, Thanks !

    You need to change the image resolution to 298 x 156 for the 7945G, 7965G.
    The 7970G/7971G/7975G supports 298 x 168.
