Load QNT image. The QNT images assumed to be 8-bit RGBA image. Returning img is actually an *image.NRGBA type.

Types ¶

type AliceArch ¶

type AliceArch struct {
	Type  FileType
	Entry []FileEntry // info of file entries in the archive
}

AliceSoft ALD/AFA archive

func OpenAFA ¶

func OpenAFA(rs io.ReadSeeker) (afa *AliceArch, err error)

Load file info of Alicesoft AFA archive. An AFA archive may has ".afa" extension.

func OpenALD ¶

func OpenALD(rs io.ReadSeeker) (ald *AliceArch, err error)

Load file info of Alicesoft ALD archive file. An ALD archive may have an extension of ".ald", ".alk" and ".dat".

func (p *AliceArch) Read(r io.ReadSeeker, entryIndex int) (data []byte, err error)

Read the data body of a file entry. entryIndex is an index of p.Entry, and r must be the open file handle of the archive file

func (*AliceArch) Size ¶

func (p *AliceArch) Size() int

Number of entries in the archive

type FileEntry ¶
