Hi all,
i want to display images with the ui-element IWDImage. My problem is, that i read an image from a fpt-server with the function 'FTP_SERVER_TO_R3'. This runs very good. But now i have the image-source in a itab from the type BLOB.
How can i bind a BLOB to the source of an IWDImage element or how can i display an image, that i have in a itab with type BLOB?
I hope somebody can help me!
Regards,
Florian
If you have the binary content of the image in memory, you need to push it into the ICM Cache in order to generate a temporary URL which you can reference in an Image UI element. I'm not sure what you mean my IWDImage. That sounds like Web Dynpro Java, not Web Dynpro ABAP.
Here is a sample of how to publish content into the ICM Cache:
****Create the cached response object that we will insert our content into
data: cached_response type ref to if_http_response.
create object cached_response
type
cl_http_response
exporting
add_c_msg = 1.
* cached_response->set_compression( options = cached_response->IF_HTTP_ENTITY~CO_COMPRESS_IN_ALL_CASES ).
try. " ignore, if compression can not be switched on
call method cached_response->set_compression
exporting
options = cached_response->co_compress_based_on_mime_type
exceptions
others = 1.
catch cx_root.
endtry.
****set the data and the headers
data: l_app_type type string.
cached_response->set_data( lv_image ).
l_app_type = 'image/png'.
cached_response->set_header_field( name = if_http_header_fields=>content_type
value = l_app_type ).
cached_response->set_status( code = 200 reason = 'OK' ).
cached_response->server_cache_expire_rel( expires_rel = 60 ).
data: guid type guid_32.
call function 'GUID_CREATE'
importing
ev_guid_32 = guid.
concatenate '/sap/public' '/' guid '.' 'png' into lv_image_url.
****Cache the URL
cl_http_server=>server_cache_upload( url = lv_image_url
response = cached_response ).
wd_context->get_element( )->set_attribute(
name = `IMAGE_URL`
value = lv_image_url ).
