Description

Fields

Public FontBidiMode: TFontBidiMode;

Specifies the base direction of the text (cf Unicode). By default, it is automatically determined by the first strongly oriented character. You can specify another base direction here however it is not taken into account by the LCL on Linux.

Public FontName: string;

Specifies the font to use. Unless the font renderer accept otherwise, the name is in human readable form, like 'Arial', 'Times New Roman', ...

Public FontOrientation: integer;

Specifies the rotation of the text, for functions that support text rotation. It is expressed in tenth of degrees, positive values going counter-clockwise.

Public FontQuality: TBGRAFontQuality;

Specifies the quality of rendering. Default value is ''fqSystem''. See [[BGRABitmap Miscellaneous types|miscellaneous types]]

Public FontStyle: TFontStyles;

Specifies the set of styles to be applied to the font. These can be ''fsBold'', ''fsItalic'', ''fsStrikeOut'', ''fsUnderline''. So the value [''fsBold'',''fsItalic''] means that the font must be bold and italic. See [[BGRABitmap Miscellaneous types|miscellaneous types]]

Public FontVerticalAnchor: TFontVerticalAnchor;

Specifies how the font is vertically aligned relative to the start coordinate. See [[BGRABitmap Miscellaneous types|miscellaneous types]]

Protected FXorMask: TBGRACustomBitmap;

This item has no description.

Public HotSpot: TPoint;

Cursor position for mouse pointer

Public ResampleFilter: TResampleFilter;

Resample filter is used when resizing the bitmap. See [[BGRABitmap Miscellaneous types#Images and resampling|resampling types]]

Public ScanInterpolationFilter: TResampleFilter;

Scan interpolation filter is used when the bitmap is used as a scanner (interface ''IBGRAScanner'')

Public ScanMaskChannel: TChannel;

Average color of the image

Public property AveragePixel: TBGRAPixel Read GetAveragePixel;

Average color (including alpha) of the image

Public property Bitmap: TBitmap Read GetBitmap;

Bitmap in a format compatible with the current GUI. Don't forget to call ''InvalidateBitmap'' before using it if you changed something with direct pixel access (''Scanline'' and ''Data'')

Public property Canvas: TCanvas Read GetCanvas;

Canvas provided by the GUI

Public property CanvasAlphaCorrection: boolean Read GetCanvasAlphaCorrection Write SetCanvasAlphaCorrection;

Specifies if the alpha values must be corrected after GUI access to the bitmap

Public property CanvasDrawModeFP: TDrawMode read GetCanvasDrawModeFP write SetCanvasDrawModeFP;

Draw mode to used when image is access using FreePascal functions and ''Colors'' property

Public property CanvasOpacity: byte Read GetCanvasOpacity Write SetCanvasOpacity;

Opacity to apply to changes made using GUI functions, provided ''CanvasAlphaCorrection'' is set to ''True''

Public property CustomPenStyle: TBGRAPenStyle read GetCustomPenStyle write SetCustomPenStyle;

Custom pen style. See [[BGRABitmap Geometry types|geometric types]]

Public property FontAntialias: Boolean read GetFontAntialias write SetFontAntialias;

Public property FontFullHeight: integer read GetFontFullHeight write SetFontFullHeight;

Specifies the height of the font in pixels, taking into account the additional line spacing defined for the font

Public property FontHeight: integer Read GetFontHeight Write SetFontHeight;

Specifies the height of the font in pixels without taking into account additional line spacing. A negative value means that it is the full height instead (see below)

Public property FontPixelMetric: TFontPixelMetric read GetFontPixelMetric;
