SkColorTable Class Reference

SkColorTable holds the lookup tables for each channel (ARGB) used to define the filter behavior of SkColorFilters::Table, and provides a way to share the table data between client code and the returned SkColorFilter. More...

class SkTableColorFilter
 

Detailed Description

SkColorTable holds the lookup tables for each channel (ARGB) used to define the filter behavior of SkColorFilters::Table, and provides a way to share the table data between client code and the returned SkColorFilter.

Once created, an SkColorTable is immutable.

◆ blueTable()

◆ Deserialize()

◆ flatten()

◆ greenTable()

◆ Make() [2/2]

)

◆ redTable()

const uint8_t* SkColorTable::redTable ( ) const
inline

◆ ref()

void SkRefCntBase::ref ( ) const
inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

◆ unique()

bool SkRefCntBase::unique ( ) const
inlineinherited

May return true if the caller is the only owner.

Ensures that all previous owner's actions are complete.

◆ unref()

void SkRefCntBase::unref ( ) const
inlineinherited

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.
