Writing multiline text in pdf page - pdf

Question

I want to write a multiline text, I've tried this:
6 0 obj
<</Length 59>>
stream
BT /F1 24 Tf 100 520 Td (This is test\n This is test)Tj ET
endstream
endobj
But I am not getting a new line. Is there a simple way to achieve that or I must create another stream with position of the next line?
This is the full code:
%PDF-1.5
1 0 obj <</Type /Catalog /Pages 2 0 R>>
endobj
2 0 obj <</Type /Pages /Kids [3 0 R] /Count 1>>
endobj
3 0 obj<</Type /Page /Parent 2 0 R /Resources 4 0 R /MediaBox [0 0 500 700] /Contents 6 0 R>>
endobj
4 0 obj<</Font <</F1 5 0 R>>>>
endobj
5 0 obj<</Type /Font /Subtype /Type1 /BaseFont /Helvetica>>
endobj
6 0 obj
<</Length 75>>
stream
BT
/F1 24 Tf
100 520 Td
(This is test) Tj
T*
(This is test) Tj
ET
endstream
endobj

Answer 1

You may want to do something like this:
BT
/F1 24 Tf
30 TL
100 520 Td
(This is test) Tj
T*
(This is test) Tj
ET
or the shorter form:
BT
/F1 24 Tf
30 TL
100 520 Td
(This is test) Tj
(This is test) '
ET
You might want to read up on section 9.4.3 Text-Showing Operators in the PDF specification ISO 32000-1.
P.S.: Added text leading TL operators.
