A still graphics to video generator using gdk-pixbuf
notes: >
Pixbuf has builtin scaling. It will rescale the originally rendered title to
whatever the consumer requests. Therefore, it will lose its aspect ratio if
so requested, and it is up to the consumer to request a proper width and
height that maintains the image aspect.
parameters:
- identifier: argument
title: File
type: string
description: >
The name of a graphics file loadable by a gdk-pixbuf loader.
See the output of gdk-pixbuf-query-loaders.
Definitely png, jpeg, tiff, pnm, and xpm will work.
If "%" in filename, the filename is used with sprintf to generate a
filename from a counter for multi-file/flipbook animation. The file
sequence ends when numeric discontinuity >100.
If the file sequence does not begin within the count of 100 you
can pass the begin property like a query string parameter, for
example: anim-%04d.png?begin=1000.
If filename contains "/.all.", suffix with an extension to load all
pictures with matching extension from a directory.
If filename contains the string "<svg", then pixbuf tries to load the
filename as inline SVG XML, which is convenient for melt commands.
