Loader/generator for Images of Music Scores
The loader/generator module provides to load and prepare the images used by Music Editor to visualise the music page directly from the image of the music sheet. These images are used also to realise the paging mechanism during the execution with or without audio. An image loaded has an own file with musical information in accord with the IWF format as indicated in the following table:
To define the information in the IWF file, when images
are loaded by the loader module the Edit Image dialog window appears in
order to fix the requested parameters: measure, url, label, metronomic
indication and time signature. The most important musical informations
are located in the first image in this sense metronomic indication and
time signature have to be considered mandatory, they are necessary to realize
the execution with images.To produce images, it’s necessary to use a slicer
to create the images from the main image of music sheet acquired with a
scanner. So, the relationship between slicer and loader/generator is the
following:
Source images are in GIF format, other formats are possible but they must be converted. The graphic resolution of image has to be at least 300 d.p.i., this is a good resolution because images can be manipulated without losing information. Moreover, during the paging execution in the music editor, images are zoomed in or out to be visualized entirely and adjusted to create the page in the graphic area, in this context resolution is very important to maintain the quality of images.
Subimages produced by slicer are in gif format.
