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.
21 - identifier: argument
25 The name of a graphics file loadable by Qt.
27 If "%" in filename, the filename is used with sprintf to generate a
28 filename from a counter for multi-file/flipbook animation. The file
29 sequence ends when numeric discontinuity >100. If the file sequence
30 does not begin with the count of 100, you can also embed the number
31 of the first image between the "%" and a "d", "i", or "u".
33 If filename contains "/.all.", suffix with an extension to load all
34 pictures with matching extension from a directory.
36 If filename contains the string "<svg", then qimage tries to load the
37 filename as inline SVG XML, which is convenient for melt commands.

86 - identifier: force_reload
