DP_CREATE_URL from application server cropped image

crepmaster — Tue, 14 Jul 2020 14:16:35 GMT

hello Folks i'm having an issue with DP_CREATE_URL loading a jpg in a container. the image is cropped and i can't manage to understand how have the full image.

here is my piece of code

TYPES pict_line(256) TYPE x.
  DATA: lt_pict_tab  TYPE TABLE OF pict_line,
         wa_pict_line TYPE pict_line,
         len          TYPE i,
         lv_size TYPE i.

  DESCRIBE FIELD wa_pict_line LENGTH len IN BYTE MODE.
  OPEN DATASET i_url FOR INPUT IN BINARY MODE.
  IF sy-subrc = 0.
    DO.
      READ DATASET i_url INTO wa_pict_line MAXIMUM LENGTH len.
      IF sy-subrc = 0.
        lv_size =  XSTRLEN( wa_pict_line ) + lv_size.
        APPEND wa_pict_line TO lt_pict_tab.
      ELSE.
        EXIT.
      ENDIF.
    ENDDO.
  ENDIF.
  CLOSE DATASET i_url.
  CALL FUNCTION 'DP_CREATE_URL'
    EXPORTING
      type                       = 'IMAGE'
      subtype                    = cndp_sap_subtype_unknown
      size                       = lv_size
*   DATE                       =
*   TIME                       =
*   DESCRIPTION                =
*   LIFETIME                   =
*   CACHEABLE                  =
*   SEND_DATA_AS_STRING        =
    TABLES
      data                       = lt_pict_tab
    CHANGING
      url                        = lv_url
 EXCEPTIONS
   dp_invalid_parameter       = 1
   dp_error_put_table         = 2
   dp_error_general           = 3
   OTHERS                     = 4.

then i just use

CALL METHOD lo_picture->load_picture_from_url_async
EXPORTING
url = lv_url.

what do i miss please?

Is it a size issue?

Thanx in advance

issue solved by changing tthe code to:

  OPEN DATASET i_url FOR INPUT IN BINARY MODE.
  IF sy-subrc = 0.
    mlen = 1024.
    alen = 9999.
    WHILE alen <> 0.
      READ DATASET i_url INTO buffer MAXIMUM LENGTH mlen ACTUAL LENGTH alen.
      IF sy-subrc = 0.
        CONCATENATE content buffer INTO content IN BYTE MODE.
      ENDIF.
    ENDWHILE.
    CLOSE DATASET i_url.

    CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
      EXPORTING
        buffer        = content
      IMPORTING
        output_length = blob_size
      TABLES
        binary_tab    = blob.

    CALL FUNCTION 'DP_CREATE_URL'
      EXPORTING
        type                 = 'IMAGE'
        subtype              = 'JPG'
        size                 = blob_size
      TABLES
        data                 = blob
      CHANGING
        url                  = lv_url
      EXCEPTIONS
        dp_invalid_parameter = 1
        dp_error_put_table   = 2
        dp_error_general     = 3
        OTHERS               = 4.
  ENDIF.
