Method Details

getOrCreateRasterizedAvatarFile

public com.atlassian.dc.filestore.api.FileStore.Path getOrCreateRasterizedAvatarFile(Avatar avatar,
 Avatar.Size size,
 InputStream inputStream)
                                                                              throws IOException

Description copied from interface: AvatarTranscoder

Creates a PNG image file for the given avatar based on the base avatar image file which should be in SVG format. The created file is also saved on disk. The subsequent requests for the same avatar and size will not trigger the conversion, previously saved file will be returned.

Specified by:

getOrCreateRasterizedAvatarFile in interface AvatarTranscoder

Parameters:

avatar - to be transcoded

size - of requested raster

inputStream - the data of the avatar to be transcoded

Returns:

a handle to avatar image file in PNG format

Throws:

IOException

transcodeAndTag

public void transcodeAndTag(InputStream inputStream,
 OutputStream outputStream)
                     throws IOException

Description copied from interface: AvatarTranscoder

Converts given SVG data to PNG format. The default avatar size will be used which is Avatar.Size.MEDIUM.

Specified by:

transcodeAndTag in interface AvatarTranscoder

Parameters:

inputStream - to be converted

outputStream - to which the result should be written

Throws:

IOException

transcodeAndTag

public byte[] transcodeAndTag(String imageKey,
 InputStream inputStream,
 Avatar.Size size)
                       throws IOException

Description copied from interface: AvatarTranscoder

Converts a given SVG data to PNG format.

This method will save the converted image to disk so that if the method is invoked once again with the same imageKey and size the previous result will be returned. Therefore it is very important to choose imageKey carefully - it should uniquely identify the image.

Specified by:

transcodeAndTag in interface AvatarTranscoder

Parameters:

imageKey - name of the file that

inputStream - svg data

size - size of the output

Returns:

byte array containing the PNG image

Throws:

IOException
