GraphType unit

graphtype.pp contains graphic-related platform-independent types and utility functions.

graphtype.pp is part of the LazUtils package.

Classes and records

TRawImage	object	An uncompressed graphics image (bitmap).
TRawImageDescription	object	Descriptor object for the image format of devices and raw (uncompressed) image data.
TRawImageLineStarts	object	TRawImageLineStarts - contains a list of the start positions of the lines in the Raw Image.
TRawImagePosition	record	Record describing a position in Raw Image data.

Procedures and functions

CopyImageData	function	CopyImageData - copies data from ASource to ADestination, returning True if successful.
GetBitsPerLine	function	GetBitsPerLine - returns the number of bits per line (as a pointer).
GetBytesPerLine	function	GetBytesPerLine - returns the number of bytes per line (as a pointer).
RawImageQueryFlagsToString	function	Converts the specified set of raw image query flags to a String value.

Types

PRawImage	type	PRawImage - pointer to a TRawImage.
PRawImageDescription	type	Pointer to
PRawImageLineStarts	type	PRawImageLineStarts - pointer to TRawImageLineStarts.
PRawImagePosition	type	PRawImagePosition - pointer to a TRawImagePosition.
TGraphicsBevelCut	enumeration	Represents bevel drawing styles.
TGraphicsColor	type	Defines the Integer range type with values that can be used for colors.
TGraphicsDrawEffect	enumeration	Represents drawing effects which can be applied to graphic elements.
TGraphicsFillStyle	enumeration	Indicates how a surface area is filled with a given color.
TPointArray	type	Type used to store an array of TPoint values.
TRawImageBitOrder	enumeration	Bit order for raw image data scan lines.
TRawImageByteOrder	enumeration	The LSB/MSB-first byte order of pixel data.
TRawImageColorFormat	enumeration	Color format for raw image data.
TRawImageLineEnd	enumeration	The alignment of raw image scanlines.
TRawImageLineOrder	enumeration	The first stored line of pixels can represent the logical top or bottom of the displayed image.
TRawImageQueryFlag	enumeration	Image formats supported by a device, or present in image data.
TRawImageQueryFlags	set	Set type used to store values from the TRawImageQueryFlag enumeration.

Constants

DefaultByteOrder

constant

Byte order for raw image data on the platform or widgetset.

Variables

DisabledDrawEffectStyle	variable	Controls the appearance of disabled images.
MissingBits	variable	Used to pad bit data in a raw image to a specific precision and byte boundaries.
