Member Function Documentation

◆ canRender()

XCFHandler::canRender ( $file )

Parameters

File $file

Returns: bool

Reimplemented from ImageHandler.

Definition at line 220 of file XCF.php.

Get width and height from the XCF header.

Parameters

File \| FSFile	$image
string	$filename

Returns: array

References $header, color, getXCFMetaData(), and none().

◆ getMetadata()

XCFHandler::getMetadata	(	$file,
		$filename
	)

Store the channel type.

Greyscale files need different command line options.

Parameters

File \| FSFile	$file	The image object, or false if there isn't one. Warning, FSFile::getPropsFromPath might pass an (object)array() instead (!)
string	$filename	The filename

Returns: string

Reimplemented from MediaHandler.

Definition at line 157 of file XCF.php.

References $header, getXCFMetaData(), and serialize().

◆ getScalerType()

XCFHandler::getScalerType	(	$dstPath,
		$checkDstPath = `true`
	)

protected

Must use "im" for XCF.

Parameters

string	$dstPath
bool	$checkDstPath

Returns: string

Reimplemented from BitmapHandler.

Definition at line 208 of file XCF.php.

◆ getThumbType()

XCFHandler::getThumbType	(	$ext,
		$mime,
		$params = `null`
	)

Render files as PNG.

Parameters

string	$ext
string	$mime
array	$params

Returns: array

Reimplemented from MediaHandler.

Definition at line 52 of file XCF.php.

◆ getXCFMetaData()

static XCFHandler::getXCFMetaData ( $filename )

static

Metadata for a given XCF file.

Will return false if file magic signature is not recognized

Author: Hexmode; Hashar

Parameters

string $filename Full path to a XCF file

Returns: bool|array Metadata Array just like PHP getimagesize()

Definition at line 92 of file XCF.php.

References $header, a, wfDebug(), wfUnpack(), and zero.

Referenced by getImageSize(), and getMetadata().

◆ isMetadataValid()

XCFHandler::isMetadataValid	(	$file,
		$metadata
	)

Should we refresh the metadata.

Parameters

File	$file	The file object for the file in question
string	$metadata	Serialized metadata

Returns: bool One of the self::METADATA_(BAD|GOOD|COMPATIBLE) constants

Reimplemented from MediaHandler.

Definition at line 192 of file XCF.php.

References MediaHandler\METADATA_BAD, and MediaHandler\METADATA_GOOD.

◆ mustRender()
