Interface to the KDE Image IO plugin architecture.
This library allows KDE applications to read and write images in a variety of formats, transparently via the QImage and QPixmap load and save methods.
The image processing backends are written as image handlers compatible with the QImageIO handler format. The backends are loaded on demand when a particular format is requested. Each format can be identified by a unique type id string.
Currently supported formats include:
Simply call the KImageIO::registerFormats() static method declared in kimgageio.h.

| enum Mode { Reading, Writing } | Mode |
Possible image file access modes.
Used in various KImageIO static function.
| void registerFormats ()
| registerFormats |
[static]
Registers all KImageIO supported formats.
| bool canWrite (const QString& type)
| canWrite |
[static]
Checks if a special type is supported for writing.
Parameters:
| the | type id of the image type |
Returns: true if the image format can be written
| bool canRead (const QString& type)
| canRead |
[static]
Checks if a special type is supported for reading.
Parameters:
| the | type id of the image type |
Returns: true if the image format can be read
| QStringList types (Mode mode = Writing)
| types |
[static]
Returns a list of all KImageIO supported formats.
Parameters:
| mode | Tells whether to retrieve modes that can be read or written. |
Returns: a list of the type ids
| QString pattern (Mode mode = Reading)
| pattern |
[static]
Returns a list of patterns of all KImageIO supported formats.
These patterns can be passed to KFileDialog::getOpenFileName() or KFileDialog::getSaveFileName(), for example.
Parameters:
| mode | Tells whether to retrieve modes that can be read or written. |
| QString suffix (const QString& type)
| suffix |
[static]
Returns the suffix of an image type.
Parameters:
| type | the type id of the file format |
Returns: the suffix of the file format or QString::null if it does not exist
| QString typeForMime (const QString& mimeType)
| typeForMime |
[static]
Returns the type of a MIME type.
Parameters:
| mimeType | the MIME type to search |
Returns: type id of the MIME type or QString::null if the MIME type is not supported
| QString type (const QString& filename)
| type |
[static]
Returns the type of given filename.
Parameters:
| filename | the filename to check |
Returns: if the file name's suffix is known the type id of the file type, otherwise QString::null
| QStringList mimeTypes ( Mode _mode = Writing )
| mimeTypes |
[static]
Returns a list of MIME types for all KImageIO supported formats.
Parameters:
| mode | Tells whether to retrieve modes that can be read or written. |
Returns: a list if MIME types of the supported formats
| bool isSupported ( const QString& _mimeType, Mode _mode = Writing )
| isSupported |
[static]
Test to see whether a MIME type is supported to reading/writing.
Parameters:
| _mimeType | the MIME type to check |
| _mode | Tells whether to check for reading or writing capabilities |
Returns: true if the type is supported
| QString mimeType ( const QString& _filename )
| mimeType |
[static]
Returns the MIME type of _filename.
Parameters:
| _filename | the filename to check |
Returns: the MIME type of the file, or QString::null
