Store image in compressed format.

Description

Without this flag set every image is stored in uncompressed format. When QUL_RESOURCE_COMPRESSION is set, an image is stored with PNG compression and will be decompressed into the cache when needed. This reduces the size of the binary but adds decompression overhead.

This flag implies that QUL_RESOURCE_CACHE_POLICY is "OnDemand".

Notes:

• The LodePNG decompression library is linked into the binary if compression is enabled for any asset.
• Image caching must be enabled.
• Source file properties must be set before adding files to the application using the qul_add_resource function.

Since

This property was introduced in Qt Quick Ultralite 1.1.
