Re: tdf#156333: Implementing Text Effects

[Владислав Тараканов]

We created a new item "SvxTintItem" and updated include/vcl/font.hxx by adding methods for reading and setting tint. We tried to add processing of this value to vcl/source/outdev/text.cxx, to the ImplDrawSpecialText method. At the same time, we started looking for where the tint value was exported.

During the search we found that tint is already used in ComplexColor. We re-checked the use of attributes in unomap1 and unomapproperties and found out that UNO_NAME_CHAR_COLOR_TINT_OR_SHADE is used there. Is there a possibility that we did not need to create a new item, but could have applied the existing tint value processing?
