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

59 description: How long (in frames) to repeat each picture in file sequences.
66 - identifier: meta.media.width
69 description: The original, unscaled width of the rendered image.
72 - identifier: meta.media.height
75 description: The original, unscaled height of the rendered image.
81 description: The last requested scaled image width.
87 description: The last requested scaled image height.
90 - identifier: force_reload
93 Reload the file instead of using its cached image. This property
94 automatically resets itself once it has been set 1 and processed.
99 - identifier: disable_exif
100 title: Disable auto-rotation
106 - identifier: force_aspect_ratio
107 title: Sample aspect ratio
109 description: Optionally override a (mis)detected aspect ratio
113 title: Loop sequence of images indefinitively
114 description: when 1 (default) loop sequences of images, when 0, play them only once
