Member Function Documentation

GetAvailableMemory()

static size_t SRL::VDP1::GetAvailableMemory ( )

inlinestatic

Get free available memory left for textures on VDP1.

Returns

Number of bytes left

GetGouraudTable()

static Types::HighColor * SRL::VDP1::GetGouraudTable ( )

inlinestatic

Get the start location of the gouraud table.

Returns

HighColor* Start location of the gouraud table

GetTextureCount()

static uint16_t SRL::VDP1::GetTextureCount ( )

inlinestatic

Get the number of currently loaded textures.

Returns

Number of currently loaded textures

ResetTextureHeap()

static void SRL::VDP1::ResetTextureHeap ( const uint16_t index )

inlinestatic

Reset texture heap to specified index.

Parameters

index

Index to reset to (texture on this index will be overwritten on next TryLoadTexture(); call)

TryLoadTexture() [1/2]

static int32_t SRL::VDP1::TryLoadTexture ( const uint16_t width, const uint16_t height, const CRAM::TextureColorMode colorMode, const uint16_t palette, void * data )

inlinestatic

Try to load a texture.

Parameters

width	Texture width
height	Texture height
colorMode	Color mode
palette	Palette start identifier in color RAM (not used in RGB555 mode)
data	Texture data

Returns

Index of the loaded texture

TryLoadTexture() [2/2]

static int32_t SRL::VDP1::TryLoadTexture ( SRL::Bitmap::IBitmap * bitmap, int16_t(*)(SRL::Bitmap::BitmapInfo *) paletteHandler = nullptr )

inlinestatic

Try to load a texture.

Parameters

bitmap	Texture to load
paletteHandler	Palette loader handling (expects index of the palette in CRAM as result, only needed for loading paletted image)

Returns

Index of the loaded texture
