Re: My own Harmony Projekt is very slow
The BMP asset that you have imported into Composer is actually stored in it's native raw format in the configuration save file. The configuration file is the configuration.xml file that resides under src/system_config/<configuration name> folder.
In order to provide a more accurate run-time simulation, all image assets needs to be processed per the choices made in the Asset Manager (such as compression settings, color format, palette etc). When Composer launches, it tries to run all these processes on the image assets stored in the configuration file. It also does that same when at generation time.
Of all the image asset conversion process, the most egregious one is the RLE. Specifically, RLE on large resolution, low detail images with very little variation in color.
We are aware of this problem and are making plans to improve this in the future. It will be beyond the v2.05 release, however.
As a work-around, have the image asset processed as a JPEG would speed this up as well as providing comparable compression capability. Another alternative is to see if there are parts of the image that can be rendered using a panel widget with a fill color only use an image for the complicated areas.
