forked from amazingfate/help
4453c0b2ed
and also drop the language that was changed to implied previously/defaults to
en-US unless specified.
This change doesn't affect translations, only the content of the
paragraph/headings is extracted.
done with:
perl -CSD -pi -e 'BEGIN {$base = qr/role="heading"|level="(?<level>\d+)"|(?<id>id="[^"]+")/;} s#<paragraph(((\s+($base)){3})|(\s+($base|xml-lang="en-US")){4})>(?<body>.*?)</paragraph>#<h$+{level} $+{id}>$+{body}</h$+{level}>#g'
and manually undoing the one that uses <sup>in body that's not valid
according to the dtd in the h tags.

Image compression is a type of data compression applied to digital images, to reduce storage size or transmission time. Compression may take advantage of visual perception and the statistical properties of image data to preserve information quality.</paragraph>
|
|
<paragraph role="paragraph" id="par_id511534716948194" xml-lang="en-US">Image compression can be lossless or lossy. Lossless compression allows the original image to be perfectly reconstructed from the compressed data. In contrast, lossy compression permits reconstruction only of an approximation of the original image, therefore with some loss of quality, though usually with improved compression rates (and therefore reduced file sizes).</paragraph>

A value of 100 means no quality loss and a value of 0 may result in a very poor image. The default value of 90 produces very good results and significant image data size reduction.</paragraph>
