How to Embed Thumbnail image on an Jpeg Image

beemaneni

Hi Friends,

Eid Mubarak to all.......:-)

Here i come up with a problem of how to embed thumbnail property in to an jpeg image in qml.As we know the frame format has metadata,image and thumbanil in it.Here i create thumbnail using rectangle(128x128) and using Exif properties i need to embed on original image..How do i do that..Any guidance and help would be highly appreciated..

Thanks in Advance friends,

Hi,

For that you'll need to go lower-level. AFAIK Qt does not provide any facility to embedded thumbnails, you'll have to write a helper class using the jpeg library to update your image file with it

Do you want just embed the image inside image ? Is it ok if the final image is displayed on widget ?

@ Dheerendra what beemameni wants is not to superpose two images but to write the thumbnail version in the "meta-data" of the original image
