Feature: #59591 - Image quality definable per sourceCollection¶

Description¶

The image quality of each sourceCollection entry can be configured. Integrators can already render images with the predefined quality set by LocalConfiguration.php. To decrease the quality of larger images (e.g. double density) in order to lower the file size, integrators can configure the parameter quality of the matching sourceCollection now.

The TypoScript setup can be configured as followed (e.g.):

# for small retina images
tt_content.image.20.1.sourceCollection.smallRetina.quality = 80

# for large retina images
tt_content.image.20.1.sourceCollection.largeRetina.quality = 65

If the new parameter is not set, TYPO3 will use to the default quality of LocalConfiguration.

Impact¶

The rendering of sourceCollection stays as it is. Users can additionally selectively control the quality of jpeg by TypoScript setup.
