jpeg image raw data from sql

jpeg image raw data from sql

(OP)
All,

I am using a java tool for test execution which stores the screen captures in SQL. The image is stored as raw data, am not sure about the format, may be base64. Am trying to write a wrapper in tcl to retrieve that data from SQL, build the image and store it in the local machine.

This is where i am,

package require Img
foreach file [glob *.jpg] {
set root [file rootname $file]
set image [image create photo -file $file]
foreach {format suffix} {JPEG jpg GIF gif PNG png} {
$image write $root.$suffix -format $format
}
}

This code takes an image as input and creates copies in other formats (jpg -> png, png -> jpg etc.,) But i need to pass the data stored in SQL which goes like this, "0xFFD8FFE000104A46494600010101006000600000FFDB0043000F0A0B0D0B090F0D0C0D11100F11162518161414162D20221B25352F3837342F34333B4255483B3F503F33344A644B50575A5F605F3947686F675C6E555D5F5BFFDB0043011011111613162B18182B5...." and so on for 1 image. I used the command, 'image create photo data <data>' but it doesn't work. I tried decoding, binary, hex conversion, but nothing works. Any help would be greatly appreciated.

Thanks,
Madhubala.
