Reg: Display image form application server

Former Member — Mon, 04 Aug 2008 07:32:20 GMT

Hi Experts,

I have an image stored in application server for eg d:\test.gif.

My requirement is to display the image from this path into a container in screen programming.

How can i achieve it. Kindly help.

I tried using load_picture_from_url method of class cl_gui_picture, its not working.

If i try to display an image from presentation server using this class and method its working fine. But my requirement is to display it form application server.

Help me on this.

Thanks and Regards

Naveen

To Download a File from Application Server

use the folloeing code

OPEN DATASET <filename>

FOR INPUT/OUTPUT/APPEND

IN TEXTMODE

ENCODING DEFAULT.

READ DATASET <filename> INTO <workarea>

CLOSE DATASET <filename>.

First download the image to presentation server from application server and then Load the Image using your approach with the classes you mentioned.

Hi Naveen,

If the image that you are displaying is lying outside of the ABAP Application Server, you can use the above mentioned method. (load_picture_from_url).

But if the same document is lying in ABAP Application Server, then you can use the BDS ( Business Document Server ) to manage data. This is a new tool. Below is the link and sample demo code which will give you a good overview of the same.

The first link is place which will give u the sample code.

Hi Naveen,

Below is the code base which is used to upload a picture from the SAP Application Server.


    TYPES pict_line TYPE x LENGTH 1022.
    DATA l_mime_api   TYPE REF TO if_mr_api.
    DATA l_pict_wa    TYPE xstring.
    DATA l_pict_tab   TYPE TABLE OF pict_line.
    DATA l_length     TYPE i.
    DATA l_url        TYPE c LENGTH 255.

    l_mime_api = cl_mime_repository_api=>get_api( ).

    l_mime_api->get(
      EXPORTING i_url = '/SAP/PUBLIC/BC/ABAP/Sources/PLANE.GIF'
      IMPORTING e_content = l_pict_wa
      EXCEPTIONS OTHERS = 4 ).

    IF sy-subrc <> 0.
      RETURN.
    ENDIF.

    l_length = XSTRLEN( l_pict_wa ).
    WHILE l_length >= 1022.
      APPEND l_pict_wa(1022) TO l_pict_tab.
      SHIFT l_pict_wa BY 1022 PLACES LEFT IN BYTE MODE.
      l_length = XSTRLEN( l_pict_wa ).
    ENDWHILE.
    IF l_length > 0.
      APPEND l_pict_wa TO l_pict_tab.
    ENDIF.

    CALL FUNCTION 'DP_CREATE_URL'
      EXPORTING
        type    = 'IMAGE'
        subtype = 'GIF'
      TABLES
        data    = l_pict_tab
      CHANGING
        url     = l_url.

    picture->load_picture_from_url(
         EXPORTING url = l_url ).
    picture->set_display_mode(
         EXPORTING display_mode = picture->display_mode_stretch ).

The Entire code is available in the program DEMO_CFW.

Thanks,

Samantak.
