To display image from a rawstring.

[Former Member]

Hello everyone,

I m trying to display image on screen with CL_GUI_PICTURE. Additionally, the image is stored in database as RAWSTRING.

I have tried using  DP_CREATE_URL to create a published URL for image. Below is the code snippet which is not working. On the other hand, I am able to display image uploaded via SE78 so the container usage is fine.

TYPES: BEGIN OF ts_hex,

            hex TYPE xstring,

          END OF ts_hex.

data: lt_pic type table of ts_hex,

        ls_pic type ts_hex.

select single * into ls_table_row from <images_table>.

ls_pic-hex = ls_table_row-image_hex.

append ls_pic to lt_pic.

CALL FUNCTION 'DP_CREATE_URL'

      EXPORTING

        type     = 'IMAGE'

        subtype  = cndp_sap_tab_unknown

      TABLES

         data = lt_pic

      CHANGING

           url = lv_url.

CALL METHOD lo_picture->load_picture_from_url_async

       EXPORTING

         url = lv_url.

Hi,

Is gt_pics contains only one line?

Thanks,

Ashok.

Yes, it is one image per row. The data is something like this (this is not the entire field value as there are limitations to SE16)
