To display image from a rawstring.

Former Member — Thu, 13 Nov 2014 09:42:31 GMT

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,

Provide graphic size also in below function module.

CALL FUNCTION 'DP_CREATE_URL'
EXPORTING
TYPE = 'IMAGE'
SUBTYPE = 'X-UNKNOWN'
SIZE = GRAPHIC_SIZE
LIFETIME = 'T'
TABLES
DATA = GRAPHIC_TABLE
CHANGING
URL = URL.

Thanks,

Ashok.

Hi Ashok,

Thank you for your reply. Now program gives a short dump but I don't know what is going wrong.

Dump details:

Program SAPLOLEA

Include LOLEAU10

Row 371

Module Type (FUNCTION)

Module Name AC_FLUSH_CALL_INTERNAL

Actual code:

CREATE OBJECT lo_custom_container

EXPORTING

container_name = 'CUSTOM_CONTAINER'.

CREATE OBJECT lo_picture

EXPORTING

parent = lo_custom_container.

READ TABLE gt_pics INTO ls_image index 1.

ls_pic_data-text = ls_image-picture.

APPEND ls_pic_data TO lt_pic_data.

lv_size = xstrlen( ls_pic_data-text ).

CALL FUNCTION 'DP_CREATE_URL'

EXPORTING

type = 'IMAGE'

subtype = 'X-UKNOWN'

size = lv_size

lifetime = 'T'

TABLES

data = lt_pic_data

CHANGING

url = lv_logo_url.

CALL METHOD lo_picture->load_picture_from_url

EXPORTING

url = lv_logo_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)
