xmpGImg data to jpeg file

-

i trying extract jpg data in xapgimg:image element, know have convert data base64, getting data (i think). start seems ok "ffd8" , "ffc4" (huffman)is there, here seems go wrong, no "ffc0" , file not end "ffd9" (end of image), ideas??

are running problems getting data out of xmp packet or in decoding after that.

there couple of web hosted base64 encoder/decoders. might try going through process manually. opening file in text editor, finding "xampgimg:image" tag, copying data, pasting web based decoder , converting it, , examing structure of jpeg.

that should narrow down problem originating application inserted thumbnail, xmp extraction, or base64 decoding.

i encoder/decoder at:

(although i've not used in situation.)

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); ...
