13 A still graphics to video generator using Qt QImage
15 QImage 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.
20 - identifier: argument
24 The name of a graphics file loadable by Qt.
26 If "%" in filename, the filename is used with sprintf to generate a
27 filename from a counter for multi-file/flipbook animation. The file
28 sequence ends when numeric discontinuity exceeds 100.
30 If the file sequence does not begin within the count of 100 you
31 can pass the begin property like a query string parameter, for
32 example: anim-%04d.png?begin=1000.
34 If filename contains "/.all.", suffix with an extension to load all
35 pictures with matching extension from a directory.
37 If filename contains the string "<svg", then qimage tries to load the
38 filename as inline SVG XML, which is convenient for melt commands.

56 description: How long (in frames) to repeat each picture in file sequences.
63 - identifier: meta.media.width
66 description: The original, unscaled width of the rendered image.

72 description: The original, unscaled height of the rendered image.
78 description: The last requested scaled image width.
84 description: The last requested scaled image height.
87 - identifier: force_reload
90 Reload the file instead of using its cached image. This property
91 automatically resets itself once it has been set 1 and processed.
