Use of transparent images with MuseScore
I wondered if transparent images would work with MuseScore - and indeed they do, though the results may be unpredictable. PNG-test.mscz
The images can be any image which includes transparency - alpha layer - so typically would be in PNG format, as here. These can be created in appropriate photo editors or designer packages. The technique also works with some TIFF and GIF files, though the "degree" of transparency may vary between formats. That might mean that using some files with a wide range of colours - particularly GIF files - might not give the desired results. I've not tested that exhaustively. PNG files should generally work.
Here are examples showing a green ellipse and a reddish rounded rectangle superimposed on a MuseScore score. Unfortunately it's not always possible to get things exactly right, as MuseScore will try to reformat the score as the images are themselves moved around, or resized. I was wondering if this technique could be used, for example for marking up existing scores - for example by performers wanting to take a score, and add in their own markings.
That would require a layer (at least one) above the MS score - which could then be "written" upon using graphic or other images with transparency where appropriate. This could, for example, be useful if several people wanted to write on the same score, as each could have one or more layers linked to them, and they could "write" on their own layer in colours which would be appropriate for each of them.
Although the functionality I'm imagining doesn't quite exist yet in the current versions of MuseScore, the example here shows that it ought to be feasible.
On this occasion I went the extra mile to upload the example to MS.com so that it would display here - and maybe attract attention - but this does seem extraordinarily clunky. I shouldn't really have to do that - IMHO. :-)
If the file is downloaded users can click on the ellipse or the rounded rectangle, and move them around to see how the format and layout changes. This does work - but attempting to do a live update "inline" will not work. To see this download the example file.
Someone round here was recently asking about notation for a Messiaen score - and this technique could perhaps be useful for that kind of score - at least until MS becomes even more developed. See https://musescore.org/en/node/320598
This could be useful for future versions of MS - perhaps!
