GetItemPicture with Codeunit

(0) ShareShare
ReportReport
Posted on by Community Member

Hello,

I need to create a code unit method to get item picture.

I only have the SetItemPicture method working.

SetItemPicture(ItemNo : Code[20];Picture : BigText)
Item.GET(ItemNo);

Bytes := Convert.FromBase64String(Picture);
MemoryStream := MemoryStream.MemoryStream(Bytes);

Item.Picture.IMPORTSTREAM(MemoryStream, ItemNo, 'image/png');

Item.MODIFY;

I tried couple of example but they never work with NAV 2017

Thanks,

/Eric

    I cannot use in NAV 2017 Item.Picture.CREATEINSTREAM(IStream);

    I tried that already :(

    Try something like this

    Item.GET(ItemNo);

    Item.CALCFIELDS(Picture);

    IF NOT Item.Picture.HASVALUE THEN

     EXIT;

    FileName := FileMgt.ServerTempFileName('txt');

         FileMgt.BLOBExportToServerFile(TempBodyTempBlob,FileName);

         EXIT(Convert.ToBase64String(File.ReadAllBytes(FileName)));

         FileMgt@1001 : Codeunit 419;

         Convert@1003 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Convert";

         File@1004 : DotNet "'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.IO.File";

         FileName@1002 : Text;

    Hi, you can use below as alternative way.

    Tested is working .

    Name DataType Subtype
    Item Record Item
    Instr InStream  
    MediaRec Record Tenant Media
    MemoryStream DotNet System.IO.MemoryStream.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
    Bytes DotNet System.Array.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
    Convert DotNet System.Convert.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
    Picture BigText  

    Item.GET('1600');
    IF Item.Picture.COUNT = 0 THEN
        EXIT;

    MediaRec.GET(Item.Picture.ITEM(1));
    MediaRec.CALCFIELDS(Content);
    IF MediaRec.Content.HASVALUE THEN BEGIN
        MediaRec.Content.CREATEINSTREAM(Instr);
        MemoryStream := MemoryStream.MemoryStream();
        COPYSTREAM(MemoryStream,Instr);
        Bytes := MemoryStream.GetBuffer();

         Picture.ADDTEXT(Convert.ToBase64String(Bytes));
    END;

    MESSAGE('%1',Picture);

    RE: GetItemPicture with Codeunit

    Hi,

    After some debugging the error comes from that line

    MediaRec.GET(Item.Picture.ITEM(1)); 

    LOCAL GetItemPicture(ItemNo : Code[20];VAR Picture : BigText)
    Item.GET(ItemNo);
    MediaRec.GET(Item.Picture.ITEM(1)); 
    MediaRec.CALCFIELDS(Content);
    TempBlob.Blob := MediaRec.Content;
    TempBlob.Blob.CREATEINSTREAM(Instr);
    MemoryStream := MemoryStream.MemoryStream();
    COPYSTREAM(MemoryStream,Instr);
    Bytes := MemoryStream.GetBuffer();
    Picture.ADDTEXT(Convert.ToBase64String(Bytes));

    Create a TempBlob of Type Record 99008535

    and assign the Picture to it like below

    after Item.CALCFIELDS(Picture)

    TempBlob.Blob := Item.Picture;

    and then use the TempBlob in the FileMgt.BLOBExport(TempBlob,FileName)

    Hi,

    Thanks for your help but I cannot compile the code you send me.

    The error comes from the line 

    TempBlob.Blob := Item.Picture;

    Item Picture in NAV 2017 is no longer blob, you should get it from tenant media instead.

    Item.GET(ItemNo);
    IF Item.Picture.COUNT = 0 THEN
        EXIT;

    MediaRec.GET(Item.Picture.ITEM(1));
    MediaRec.CALCFIELDS(Content);
    IF MediaRec.Content.HASVALUE THEN BEGIN

       TempBlob.blob  = MediaRec.Content;

       //continue here

    END;
