the following needs checks if its still valid. if yes make it an github issue, if no remove from here:
test_accessing_images fails when accessing the scale via @@images
If an image scale is added to TinyMCE it gets transformed to its uid representation (as stored in plone.scale.storage). If the cropped scale gets removed the uid does not exists anymore and the referenced image in TinyMCE raises NotFound exception.
in bristol we have been talking about grayscale, sepia, watermark transforms and wanted to add this to p.a.imaging.
these functionalities will go into a separate addon.
chaining transforms shall be possible
for the integrator:
scales img/@@images
scales.scale('imagefield', scale='mini').apply('grayscale', 0.5).apply('watermark', text='mycopyright')
#and even nicer:
scales.scale('imagefield', scale='mini').grayscale(0.5)
