Types related to SSE 32 bpp blitter.
BlitterMode
The modes of blitting we can do.
Definition: base.hpp:17
The base factory, keeping track of all blitters.
Definition: factory.hpp:21
virtual Blitter * CreateInstance()=0
Create an instance of this Blitter-class.
The most trivial 32 bpp blitter (without palette animation).
Sprite * Encode(const SpriteLoader::SpriteCollection &sprite, SpriteAllocator &allocator) override
Convert a sprite from the loader to our own format.
void Draw(Blitter::BlitterParams *bp, BlitterMode mode, ZoomLevel zoom) override
Draw an image to the screen, given an amount of params defined above.
std::string_view GetName() override
Get the name of the blitter, the same as the Factory-instance returns.
How all blitters should look like.
Definition: base.hpp:29
Interface for something that can allocate memory for a sprite.
std::array< Sprite, ZOOM_LVL_END > SpriteCollection
Type defining a collection of sprites, one for each zoom level.
DECLARE_ENUM_AS_BIT_SET(GenderEthnicity) enum CompanyManagerFaceVariable
Bitgroups of the CompanyManagerFace variable.
bool HasCPUIDFlag(uint type, uint index, uint bit)
Check whether the current CPU has the given flag.

Parameters related to blitting.
Definition: base.hpp:32
Data structure describing a sprite.
Definition: spritecache.h:17
ZoomLevel
All zoom levels we know.
Definition: zoom_type.h:16
@ ZOOM_LVL_END
End for iteration.
Definition: zoom_type.h:25
