CurveAdjustments

Bitmap adjustments-

Name Value Description
AdjustExposure 0 Simulates increasing or decreasing the exposure of a photograph. When you set the adjustment member of a ColorCurveParams object to AdjustExposure, you should set the adjustValue member to an integer in the range -255 through 255. A value of 0 specifies no change in exposure. Positive values specify increased exposure and negative values specify decreased exposure.
AdjustDensity 1 Simulates increasing or decreasing the film density of a photograph. When you set the adjustment member of a ColorCurveParams object to AdjustDensity, you should set the adjustValue member to an integer in the range -255 through 255. A value of 0 specifies no change in density. Positive values specify increased density (lighter picture) and negative values specify decreased density (darker picture).
AdjustContrast 2 Increases or decreases the contrast of a bitmap. When you set the adjustment member of a ColorCurveParams object to AdjustContrast, you should set the adjustValue member to an integer in the range -100 through 100. A value of 0 specifies no change in contrast. Positive values specify increased contrast and negative values specify decreased contrast.
AdjustHighlight 3 Increases or decreases the value of a color channel if that channel already has a value that is above half intensity. You can use this adjustment to get more definition in the light areas of an image without affecting the dark areas. When you set the adjustment member of a ColorCurveParams object to AdjustHighlight, you should set the adjustValue member to an integer in the range -100 through 100. A value of 0 specifies no change. Positive values specify that the light areas are made lighter, and negative values specify that the light areas are made darker.
AdjustShadow 4 Increases or decreases the value of a color channel if that channel already has a value that is below half intensity. You can use this adjustment to get more definition in the dark areas of an image without affecting the light areas. When you set the adjustment member of a ColorCurveParams object to AdjustShadow, you should set the adjustValue member to an integer in the range -100 through 100. A value of 0 specifies no change. Positive values specify that the dark areas are made lighter, and negative values specify that the dark areas are made darker.
AdjustMidtone 5 Lightens or darkens an image. Color channel values in the middle of the intensity range are altered more than color channel values near the minimum or maximum intensity. You can use this adjustment to lighten (or darken) an image without loosing the contrast between the darkest and lightest portions of the image. When you set the adjustment member of a ColorCurveParams object to AdjustMidtone, you should set the adjustValue member to an integer in the range -100 through 100. A value of 0 specifies no change. Positive values specify that the midtones are made lighter, and negative values specify that the midtones are made darker.
AdjustWhiteSaturation 6 When you set the adjustment member of a ColorCurveParams object to AdjustWhiteSaturation, you should set the adjustValue member to an integer in the range 0 through 255. A value of t specifies that the interval [0, t] is mapped linearly to the interval [0, 255]. For example, if adjustValue is equal to 240, then color channel values in the interval [0, 240] are adjusted so that they spread out over the interval [0, 255]. Color channel values greater than 240 are set to 255.
AdjustBlackSaturation 7 When you set the adjustment member of a ColorCurveParams object to AdjustBlackSaturation, you should set the adjustValue member to an integer in the range 0 through 255. A value of t specifies that the interval [t, 255] is mapped linearly to the interval [0, 255]. For example, if adjustValue is equal to 15, then color channel values in the interval [15, 255] are adjusted so that they spread out over the interval [0, 255]. Color channel values less than 15 are set to 0.

To apply one of the eight adjustments to a bitmap, follow these steps.

  1. Create a ColorCurveParams structure, and set its adjustment member to one of the elements of the CurveAdjustments enumeration.
  2. Set the other two members (adjustValue and channel) of the ColorCurveParams structure.

DitherType

Identifies the available algorithms for dithering when a bitmap is converted.

Calling the GdipBitmapConvertFormat function of a Bitmap object changes the pixel format of that Bitmap. If the conversion results in a reduced bit depth (fewer bits per pixel), then certain colors in the original bitmap will be simulated by a dither (checkerboard) pattern made up of colors that are available in the new pixel format. The members of the DitherType enumeration identify the algorithms available for performing this dithering.

Name Value Description
DitherTypeNone 0 No dithering is performed. Pixels in the source bitmap are mapped to the nearest color in the palette specified by the palette parameter of the GdipBitmapConvertFormat function. This algorithm can be used with any palette. If the palette specified by the palette parameter does not have one of the standard fixed formats listed in the PaletteType enumeration, pass PaletteTypeCustom to the palettetype parameter.
DitherTypeSolid 1 No dithering is performed. Pixels in the source bitmap are mapped to the nearest color in the palette specified by the palette parameter of the GdipBitmapConvertFormat function. This algorithm can be used with any palette. If the palette specified by the palette parameter does not have one of the standard fixed formats listed in the PaletteType enumeration, pass PaletteTypeCustom to the palettetype parameter.
DitherTypeOrdered4x4 2 You can use this algorithm to perform dithering based on the colors in one of the standard fixed palettes. You can also use this algorithm to convert a bitmap to a 16-bits-per-pixel format that has no palette.
DitherTypeOrdered8x8 3 Dithering is performed using the colors in one of the standard fixed palettes.
DitherTypeOrdered16x16 4 Dithering is performed using the colors in one of the standard fixed palettes.
DitherTypeSpiral4x4 5 Dithering is performed using the colors in one of the standard fixed palettes.

DitherTypeErrorDiffusion 9 Dithering is performed based on the palette specified by the palette parameter of the GdipBitmapConvertFormat function. This algorithm can be used with any palette. If the palette specified by the palette parameter does not have one of the standard fixed formats listed in the PaletteType enumeration, pass PaletteTypeCustom to the palettetype parameter.
DitherTypeMax 10

DriverStringOptions

The DriverStringOptions enumeration specifies the spacing, orientation, and quality of the rendering for driver strings.

Name Value Description
DriverStringOptionsCmapLookup 1 Specifies that the string array contains Unicode character values. If this flag is not set, each value in array is interpreted as an index to a font glyph that defines a character to be displayed.
DriverStringOptionsVertical 2 Specifies that the string is displayed vertically.
DriverStringOptionsRealizedAdvance 4 Specifies that the glyph positions are calculated from the position of the first glyph. If this flag is not set, the glyph positions are obtained from an array of coordinates.
DriverStringOptionsLimitSubpixel 8 Specifies that less memory should be used for cache of antialiased glyphs. This also produces lower quality. If this flag isn’t set, more memory is used, but the quality is higher.

EmfPlusRecordType

The EmfPlusRecordType enumeration identifies metafile record types used in Windows Metafile Format (WMF), Enhanced Metafile (EMF), and EMF+ files. The elements of the EmfPlusRecordType enumeration come in three groups.

WMF and EMF records can be displayed by Windows GDI+ and by Windows Graphics Device Interface (GDI). EMF+ records can be displayed by GDI+ but not by GDI.

Elements that have the WmfRecordType prefix are analogous to constants (defined in Wingdi.h) that have the prefix META_. For example, the element WmfRecordTypeSetBkColor is analogous to the constant META_SETBKCOLOR. For more information about WMF files, see Windows-Format Metafiles.

Elements that have the EmfRecordType prefix are analogous to constants (defined in Wingdi.h) that have the prefix EMR_. For example, the element EmfRecordTypePolygon is analogous to the constant EMR_POLYGON. For more information about EMR constants, see EMR.

Elements that have the EmfPlusRecordType prefix are specific to GDI+. Most of those elements correspond to methods of the Graphics class. The remaining elements identify the header, the end of the file, and other sections of the metafile. The Constants section of this topic shows the correspondence between the EMF+ record types and the methods of the Graphics class.

Name Value Description
WmfRecordTypeSetBkColor 66049

The StringFormatFlags enumeration specifies text layout information (such as orientation and clipping) and display manipulations (such as ellipsis insertion, digit substitution, and representation of characters that are not supported by a font).

Name Value Description
StringFormatFlagsDirectionRightToLeft &h00000001 Specifies that reading order is right to left. For horizontal text, characters are read from right to left. For vertical text, columns are read from right to left. By default, horizontal or vertical text is read from left to right.
StringFormatFlagsDirectionVertical &h00000002 Specifies that individual lines of text are drawn vertically on the display device. By default, lines of text are horizontal, each new line below the previous line.
StringFormatFlagsNoFitBlackBox &h00000004 Specifies that parts of characters are allowed to overhang the string’s layout rectangle. By default, characters are first aligned inside the rectangle’s boundaries, then any characters which still overhang the boundaries are repositioned to avoid any overhang and thereby avoid affecting pixels outside the layout rectangle. An italic, lowercase letter F (f) is an example of a character that may have overhanging parts. Setting this flag ensures that the character aligns visually with the lines above and below but may cause parts of characters, which lie outside the layout rectangle, to be clipped or painted.
StringFormatFlagsDisplayFormatControl &h00000020 Specifies that Unicode layout control characters are displayed with a representative character.
StringFormatFlagsNoFontFallback &h00000400 Specifies that an alternate font is used for characters that are not supported in the requested font. By default, any missing characters are displayed with the “fonts missing” character, usually an open square.
StringFormatFlagsMeasureTrailingSpaces &h00000800 Specifies that the space at the end of each line is included in a string measurement. By default, the boundary rectangle returned by the GdipMeasureString method excludes the space at the end of each line. Set this flag to include that space in the measurement.
StringFormatFlagsNoWrap &h00001000 Specifies that the wrapping of text to the next line is disabled. NoWrap is implied when a point of origin is used instead of a layout rectangle. When drawing text within a rectangle, by default, text is broken at the last word boundary that is inside the rectangle’s boundary and wrapped to the next line.
StringFormatFlagsLineLimit &h00002000 Specifies that only entire lines are laid out in the layout rectangle. By default, layout continues until the end of the text or until no more lines are visible as a result of clipping, whichever comes first. The default settings allow the last line to be partially obscured by a layout rectangle that is not a whole multiple of the line height. To ensure that only whole lines are seen, set this flag and be careful to provide a layout rectangle at least as tall as the height of one line.
StringFormatFlagsNoClip &h00004000 Specifies that characters overhanging the layout rectangle and text extending outside the layout rectangle are allowed to show. By default, all overhanging characters and text that extends outside the layout rectangle are clipped. Any trailing spaces (spaces that are at the end of a line) that extend outside the layout rectangle are clipped. Therefore, the setting of this flag will have an effect on a string measurement if trailing spaces are being included in the measurement. If clipping is enabled, trailing spaces that extend outside the layout rectangle are not included in the measurement. If clipping is disabled, all trailing spaces are included in the measurement, regardless of whether they are outside the layout rectangle.
StringFormatFlagsBypassGDI &h80000000

Remarks

Multiple flags set can produce combined effects:

The StringFormatFlagsDirectionVertical and StringFormatFlagsDirectionRightToLeft flags can affect string alignment.

StringTrimming

The StringTrimming enumeration specifies how to trim characters from a string so that the string fits into a layout rectangle. The layout rectangle is used to position and size the display string.

Name Value Description

StringTrimmingCharacter 1 Specifies that the string is broken at the boundary of the last character that is inside the layout rectangle. This is the default.
StringTrimmingWord 2 Specifies that the string is broken at the boundary of the last word that is inside the layout rectangle.
StringTrimmingEllipsisCharacter 3 Specifies that the string is broken at the boundary of the last character that is inside the layout rectangle and an ellipsis (…) is inserted after the character.
StringTrimmingEllipsisWord 4 Specifies that the string is broken at the boundary of the last word that is inside the layout rectangle and an ellipsis (…) is inserted after the word.
StringTrimmingEllipsisPath 5 Specifies that the center is removed from the string and replaced by an ellipsis. The algorithm keeps as much of the last portion of the string as possible.

Remarks

Trimming affects only the last visible or partly visible (due to clipping) line of text.

TextRenderingHintSingleBitPerPixel 2 Specifies that a character is drawn using its glyph bitmap and no hinting. This results in better performance at the expense of quality.
TextRenderingHintAntiAliasGridFit 3 Specifies that a character is drawn using its antialiased glyph bitmap and hinting. This results in much better quality due to antialiasing at a higher performance cost.
TextRenderingHintAntiAlias 4 Specifies that a character is drawn using its antialiased glyph bitmap and no hinting. Stem width differences may be noticeable because hinting is turned off.
TextRenderingHintClearTypeGridFit 5 Specifies that a character is drawn using its glyph ClearType bitmap and hinting. This type of text rendering cannot be used along with CompositingModeSourceCopy. Windows XP and Windows Server 2003 and later versions of Windows only: ClearType rendering is supported only on Windows XP and Windows Server 2003 and later versions of Windows. Therefore, TextRenderingHintClearTypeGridFit is ignored on other operating systems even though GDI+ is supported on those operating systems.

Remarks

The quality associated with each process varies according to the circumstances. TextRenderingHintClearTypeGridFit provides the best quality for most LCD monitors and relatively small font sizes. TextRenderingHintAntiAlias provides the best quality for rotated text. Generally, a process that produces higher quality text is slower than a process that produces lower quality text.

Unit

The Unit enumeration specifies the unit of measure for a given data type.

Name Value Description
UnitWorld 0 Specifies world coordinates, a nonphysical unit.
UnitDisplay 1 Specifies display units. For example, if the display device is a monitor, then the unit is 1 pixel.
UnitPixel 2 Specifies that a unit is 1 pixel.
UnitPoint 3 Specifies that a unit is 1 point or 1/72 inch.
UnitInch 4 Specifies that a unit is 1 inch.
UnitDocument 5 Specifies that a unit is 1/300 inch.
UnitMillimeter 6 Specifies that a unit is 1 millimeter.

WarpMode

The WarpMode enumeration specifies warp modes that can be used to transform images.

Name Value Description
WarpModePerspective 0 Specifies the perspective warp mode.
WarpModeBilinear 1 Specifies the bilinear warp mode.

WrapMode

The WrapMode enumeration specifies how repeated copies of an image are used to tile an area.

Name Value Description
WrapModeTile 0 Specifies tiling without flipping.
WrapModeTileFlipX 1 Specifies that tiles are flipped horizontally as you move from one tile to the next in a row.
WrapModeTileFlipY 2 Specifies that tiles are flipped vertically as you move from one tile to the next in a column.
WrapModeTileFlipXY 3 Specifies that tiles are flipped horizontally as you move along a row and flipped vertically as you move along a column.
WrapModeClamp 4 Specifies that no tiling takes place.
