Bitmap.mui

DESCRIPTION

Bitmap.mui/Bitmap.mui

	The Bitmap class allows including self-made image data in MUI
	applications. Usually, image class was intended to be used for
	this purpose but unfortunately, its design was not very useful.

	In its most simple usage, Bitmap class just display a given
	BitMap. However, you can also tell it to do automatic color
	remapping to match the current display context and you can
	define a transparent color to make the BitMap appear on any
	background

MUIA_Bitmap_Alpha

(V20) [ISG], ULONG, 0x80423e71

DESCRIPTION

	If specified, MUI will consider the BitMap to contain
	alpha informations. The only supported BitMap format is
	32-bit ARGB. The value of MUIA_Bitmap_Alpha is an ULONG
	specifying the intensity of the alpha blitting. You 
	usually	want to specify 0xffffffff. Alpha blitting won't
	work on CLUT screens

MUIA_Bitmap_Bitmap

(V8 ) [ISG], struct BitMap *, 0x804279bd

DESCRIPTION

	This attribute specifies a pointer to a struct BitMap. Note
	that specifying only a BitMap isn't enough, you have to tell
	MUI about the pixel width and height with MUIA_Bitmap_Width
	and MUIA_Bitmap_Height too

SEE ALSO

MUIA_Bitmap_Height

(V8 ) [ISG], LONG, 0x80421560

DESCRIPTION

	Define the pixel height of the BitMap.

	Note: By default, the bitmap object has a minimum size of
	1 pixel and an unlimited maxium size. If the space is
	too small to hold your BitMap, it will be clipped.
	Usually, you will use MUIA_FixWidth and MUIA_FixHeight
	with BitMap objects to make them always exactly as big as
	the bitmap

SEE ALSO

MUIA_Bitmap_MappingTable

(V8 ) [ISG], UBYTE *, 0x8042e23d

DESCRIPTION

	Address of an array of UBYTEs, one for each color of the
	source BitMap. MUI will remap the BitMap according to the
	contents of the array.

	Since MUI applications usually don't know about their
	display environment, this tag is rarely used. Instead,
	MUIA_Bitmap_SourceColors can be used to allow context
	sensitive color remapping

SEE ALSO

MUIA_Bitmap_Precision

(V11) [ISG], LONG, 0x80420c74

DESCRIPTION

	Specify the precision value for remapping images. Use
	the same predefined values as for ObtainBestPen() here,
	e.g.

	PRECISION_EXACT
	PRECISION_IMAGE
	PRECISION_ICON
	PRECISION_GUI

MUIA_Bitmap_RemappedBitmap

(V11) [..G], struct BitMap *, 0x80423a47

DESCRIPTION

	Between MUIM_Setup and MUIM_Cleanup, this attribute will
	hold a pointer to the remapped bitmap

MUIA_Bitmap_SourceColors

(V8 ) [ISG], ULONG *, 0x80425360

DESCRIPTION

	This attribute defines the color palette of the source
	BitMap. If specified, MUI will try to locate these colors
	on the current screen and remap the BitMap accordingly.

	You can e.g. specify some great looking 8-color images
	for several buttons of your application and MUI will
	ensure they look fine even on 4-color screens or on
	screens with completely different colors.

	When running Kickstart V39 or higher, MUI will use
	ObtainBestPen() to find or create your colors.
	Below V39, a simple color-map search is performed
	to find the best matching entry, but no colors will
	be changed.

	The source palette is specified with an array of
	ULONGs, three entries per color, 32 bits per gun

EXAMPLE

	/* MagicWB-like palette for an 8-color image */

	const ULONG aboutlogo_colors[24] =
	{
	   0xaaaaaaaa,0xaaaaaaaa,0xa0a0a0a0,
	   0x00000000,0x00000000,0x00000000,
	   0xffffffff,0xffffffff,0xffffffff,
	   0x66666666,0x88888888,0xbbbbbbbb,
	   0x99999999,0x99999999,0x99999999,
	   0xbbbbbbbb,0xbbbbbbbb,0xbbbbbbbb,
	   0xbbbbbbbb,0xaaaaaaaa,0x99999999,
	   0xffffffff,0xbbbbbbbb,0xaaaaaaaa

SEE ALSO

MUIA_Bitmap_Transparent

(V8 ) [ISG], LONG, 0x80422805

DESCRIPTION

	If specified, MUI will consider this color of the BitMap
	to be transparent. A mask plane will be generated and
	used for blitting, the background will shine through.

	Currently, only 0 is supported, i.e. only color 0 can
	be made the "shine through" color

SEE ALSO

MUIA_Bitmap_UseFriend

(V11) [I..], BOOL, 0x804239d8

DESCRIPTION

	This attribute will make MUI to try to allocate the remapped
	bitmap in a way that allows fastest displaying

MUIA_Bitmap_Width

(V8 ) [ISG], LONG, 0x8042eb3a

DESCRIPTION

	Define the pixel width of the BitMap.

	Note: By default, the bitmap object has a minimum size of
	1 pixel and an unlimited maxium size. If the space is
	too small to hold your BitMap, it will be clipped.
	Usually, you will use MUIA_FixWidth and MUIA_FixHeight
	with BitMap objects to make them always exactly as big as
	the bitmap
