Detailed Description

TBBitmapFragmentMap is used to pack multiple bitmaps into a single TBBitmap.

When initialized (in a size suitable for a TBBitmap) it also creates a software buffer that will make up the TBBitmap when all fragments have been added.

Member Function Documentation

TBBitmapFragment * tb::TBBitmapFragmentMap::CreateNewFragment ( int  frag_w,
int  frag_h,
int  data_stride,
uint32_t *  frag_data,
bool  add_border 
)

Create a new fragment with the given size and data in this map.

Returns nullptr if there is not enough room in this map or on any other fail.

void tb::TBBitmapFragmentMap::FreeFragmentSpace ( TBBitmapFragment frag)

Free up the space used by the given fragment, so that other fragments can take its place.

TBBitmap * tb::TBBitmapFragmentMap::GetBitmap ( TB_VALIDATE_TYPE  validate_type = TB_VALIDATE_ALWAYS)

Return the bitmap for this map.

By default, the bitmap is validated if needed before returning (See TB_VALIDATE_TYPE)

bool tb::TBBitmapFragmentMap::Init ( int  bitmap_w,
int  bitmap_h 
)

Initialize the map with the given size.

The size should be a power of two since it will be used to create a TBBitmap (texture memory).
