Member Function Documentation

int IMG_SampleFormat::checkExtension ( const char * filename ) const

overridevirtual

Methods to determine if this is one of our recognized files. The extension is the first try. If there are multiple matches, then we resort to the magic number (when reading)

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 125 of file IMG_Sample.C.

int IMG_SampleFormat::checkMagic ( unsigned int ) const

overridevirtual

If possible, this magic numver checker will be called. This is used if the file is "seekable" (i.e. that we can rewind after checking)

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 132 of file IMG_Sample.C.

IMG_File * IMG_SampleFormat::createFile ( ) const

overridevirtual

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 119 of file IMG_Sample.C.

const char * IMG_SampleFormat::getDefaultExtension ( ) const

overridevirtual

The default extension is used to determine whether the format should appear in the device/format menus. It should not contain the '.' (i.e. "tif" not ".tif")

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 110 of file IMG_Sample.C.

const char * IMG_SampleFormat::getFormatDescription ( ) const

overridevirtual

This can be optionally overridden to return a short description of the format. By default, no description is given.

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 102 of file IMG_Sample.C.

const char * IMG_SampleFormat::getFormatLabel ( ) const

overridevirtual

If getFormatLabel() is not overridden, the label will be the same as the name.

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 95 of file IMG_Sample.C.

const char * IMG_SampleFormat::getFormatName ( ) const

overridevirtual

All formats must have a unique name (like "JPEG").

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 88 of file IMG_Sample.C.

void IMG_SampleFormat::getMaxResolution	(	unsigned &	x,
		unsigned &	y
	)		const

overridevirtual

Maximum allowable resolution for the file. If a user attempts to write an image larger than this, the image will be scaled to this resolution.

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 139 of file IMG_Sample.C.

IMG_ColorModel HDK_Sample::IMG_SampleFormat::getSupportedColorModels ( ) const

inlineoverridevirtual

Returns a bitfield of supported color models. If IMG_CM_REVERSED is set, this format stores data in BGR/ABGR format.

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 73 of file IMG_Sample.C.

IMG_DataType HDK_Sample::IMG_SampleFormat::getSupportedTypes ( ) const

inlineoverridevirtual

Returns a bitfield of data types supported by this format.

Implements IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 71 of file IMG_Sample.C.

int HDK_Sample::IMG_SampleFormat::isReadRandomAccess ( ) const

inlineoverridevirtual

Some formats can be read and written in random order. Others require strict sequential order. If these methods return false, you should read and write scanlines in ascending order. When writing, they will be cached until they can be written sequentially.

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 80 of file IMG_Sample.C.

int HDK_Sample::IMG_SampleFormat::isWriteRandomAccess ( ) const

inlineoverridevirtual

If 0 is returned, the scanlines must be written in sequential order or they will be cached until all scanlines can be written sequentially.

Reimplemented from IMG_Format.

Examples:: IMG/IMG_Sample.C.

Definition at line 81 of file IMG_Sample.C.
