Hi there,

I've disovered the following problem. If any image which is refered in SMIL slides is larger than the maximum resolution of the phone screen, the presentation does not play. According to my investigation, the issue is only with Nokia phones, at least 6220 and some others. For example, Nokia 6220 has 128x128 maximum screen resolution, hence if any of the images in the SMIL is 128x129, SMIL presentation won't play (you must scroll through the SMIL objects manually).

I would like to ask how do NowSMS gateway tries do adapt the content dynamically. I already know that it takes information from UAprofile, but which node it uses to gather the information about the resolution? For Nokia 6220, there are two of them:

<mms:MmsMaxImageResolution>352x288</mms:MmsMaxImageResolution>

and

<prf:ScreenSize>128x128</prf:ScreenSize>

According to the most papers from Nokia and other manufacturers, the maximum guaranteed resolution for a MMS image is 160x120 and it's also said, that if image is bigger, phone WILL try to resize it.

I would like to ask if any of you has faced the similar problem or if there is any workaround by playing with SMIL's layout headers or similar.

By the way, the same SMIL with Motorola C450 and some Sony Ericsson I've tried works fine.

regards,

i think something wrong with the UAProfile features. Simply try select "set to fit screen" over "default size" on the nowsms gateway when sending wallpaper over it still stay with default size instead of 'force to fit to mobile screen'.

There are two options in the NowSMS configuration...

Scale images to:

(a) Screen Size

(b) Max Supported Size

Setting (a) uses the <ScreenSize> setting.

Setting (b) uses the <MmsMaxImageResolution> setting.

If the setting that NowSMS is looking for is not present in the UAProf file, then in both cases, it will try the other setting and use that instead.

if i have a wallpaper of 128x128, and when S60 users trying to download, which features shd i use to make it to "fit screen" of S60 phones? Tried both a and b, seems it still 128x128 size on S60 phones. Testing using Nokia 6600, it just wont "fit the screen" of the 128x128 wallpaper.

I'm not sure I understand. NowSMS will only scale down the size, it won't scale it up.

It's probably easiest for me to understand with an example. Can you upload a file here, and I'll try to send it to a Nokia 6600 so that I can understand what you're referring to.
