[HTML-3316] - Add imageScale option to write out larger images for higher quality zooming
Full release of experimental option added in the October 2019 release which allows image sizes to be increased for higher quality zooming.
When running BuildVu from command line, this can be enabled using the system property -Dorg.jpedal.pdf2html.imageScale=value where value is a floating point number greater than 1.
Default value is 1, which produces images at the same size they are displayed when the zoom is 100%. A value of 1.5 will generate images at 1.5x the standard size. The maximum size of an image is capped at the size of the source image stored in the PDF file. For example if the source image is 150x150, then increasing the imageScale value will not generate an image larger than 150x150.
It is important to remember that file size grows exponentially with the scaling factor. For example, scaling an image by 2 actually multiplies the number of pixels by 4. We therefore recommend a value such as 1.5 or 2.
[HTML-3291] - Jumpy text selection in Chrome/Safari/Edge/IE
Line height has been increased which increases the selection bounds of the text in Chrome/Safari/Edge/IE, making the cursor less likely to hit the background and reverse the direction of the selection.
