Detailed Description

Initializing of the (GRF) graphics.

Definition in file gfxinit.cpp.

Function Documentation

CheckExternalFiles()

void CheckExternalFiles

(

)

Checks whether the MD5 checksums of the files are correct.

Note

Also checks sample.cat and other required non-NewGRF GRFs for corruption.

LoadGrfFile()

static uint LoadGrfFile ( const std::string &  filename, SpriteID  load_index, bool  needs_palette_remap  )

static

Load an old fashioned GRF file.

Parameters

filename	The name of the file to open.
load_index	The offset of the first sprite.
needs_palette_remap	Whether the colours in the GRF file need a palette remap.

Returns

The number of loaded sprites.

LoadGrfFileIndexed()

static void LoadGrfFileIndexed ( const std::string &  filename, std::span< const std::pair< SpriteID, SpriteID >>  index_tbl, bool  needs_palette_remap  )

static

Load an old fashioned GRF file to replace already loaded sprites.

Parameters

filename	The name of the file to open.
index_tbl	The offsets of each of the sprites.
needs_palette_remap	Whether the colours in the GRF file need a palette remap.

Returns

The number of loaded sprites.

SwitchNewGRFBlitter()

static bool SwitchNewGRFBlitter ( )

static

Check blitter needed by NewGRF config and switch if needed.

Returns

False when nothing changed, true otherwise.

< 0: no support, 1: do support, 2: both
