Member Function Documentation

◆ canRender()

XCFHandler::canRender (   $file)

Can we render this file?

Image magick doesn't support indexed xcf files as of current writing (as of 6.8.9-3)

Parameters
File$file
Returns
bool

◆ getMetadata()

XCFHandler::getMetadata (   $file,
  $filename 
)

Store the channel type.

Greyscale files need different command line options.

Parameters

string$filename
Returns
string

Reimplemented from MediaHandler.

Definition at line 157 of file XCFHandler.php.

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

◆ getScalerType()

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

Parameters
string$dstPath
bool$checkDstPath
Returns
string

string$mime
array | null$params
Returns
array

Reimplemented from MediaHandler.

Definition at line 52 of file XCFHandler.php.

◆ getXCFMetaData()

static XCFHandler::getXCFMetaData (   $filename)
staticprivate

Metadata for a given XCF file.

Will return false if file magic signature is not recognized

Author
Hexmode
Hashar
Parameters
string$filenameFull path to a XCF file
Returns
bool|array Metadata Array just like PHP getimagesize()

Definition at line 92 of file XCFHandler.php.

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

Referenced by getImageSize(), and getMetadata().

◆ isMetadataValid()

XCFHandler::isMetadataValid (   $file,
  $metadata 
)

Should we refresh the metadata.

Parameters
File$fileThe file object for the file in question
string$metadataSerialized metadata
