This introduces a general new form of polar filters. --- DOCS/man/vo.rst | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'DOCS') diff --git a/DOCS/man/vo.rst b/DOCS/man/vo.rst index 0566fd6817..92b88dc523 100644 --- a/DOCS/man/vo.rst +++ b/DOCS/man/vo.rst @@ -304,6 +304,12 @@ Available video output drivers are: ``lanczos`` Generic Lanczos scaling filter.
