Hello All,

we have a working mobile app that capture a picture and save it to the database (using the appeon_workspace.pbl)

it works with no problems we have only one issue we can not control the resolution of the picture and in same cases the image taked is huge and take a long time to be save to the database and when need it upload to the application.

we found out the it was cause by the settings of the phone (the camera used and resolution of the picture)

is any way to compress the image or change the resolution from the PB app?

Powerserver Debug options
Is PowerServer supported on Google Cloud Platform?

Hi Andres,

For how to use image SDK, please refer to attached PB case.

Hello Andres,

after you take a picture, you can reduce its size using the eon_mobile_imageex object from workaround pbl.

  • set resize options in eon_mobile_str_imageoption structure
  • reduce size by calling of_createimagewithoptions()

 

Best regards,
