     6  Font rendering units : BGRAText, BGRATextFX, BGRAVectorize, BGRAFreeType
     7
     8  This units provide a font renderer with FreeType fonts, using the integrated FreeType font engine in Lazarus.
     9  The simplest way to render effects is to use TBGRAFreeTypeFontRenderer class.
     10  To do this, create an instance of this class and assign it to a TBGRABitmap.FontRenderer property. Now functions
     11  to draw text like TBGRABitmap.TextOut will use the chosen renderer.
     12
     13  >> Note that you need to defined the default FreeType font collection
     14  >> using LazFreeTypeFontCollection unit.
     15
     16  To set the effects, keep a variable containing
     17  the TBGRAFreeTypeFontRenderer class and modify ShadowVisible and other effects parameters. The FontHinted property
     18  allows you to choose if the font is snapped to pixels to make it more readable.
     19
     20  TBGRAFreeTypeDrawer class is the class that provides basic FreeType drawing
     21  by deriving the TFreeTypeDrawer type. You can use it directly, but it is not
     22  recommended, because there are less text layout parameters. However, it is
     23  necessary if you want to create TBGRATextEffect objects using FreeType fonts.

     7{ There are different conventions for angles.
     8
     9  First is about the unit. It can be one of the following:
     10  - degrees (0..360)
     11  - radian (0..2*Pi)
     12  - tenth of degrees (0..3600)
     13  - from 0 to 65536
     14
     15  Second is about the origin. It can be one of the following:
     16  - right-most position (this is the default origin for radian and 65536)
     17  - top-most position (this is the default origin for degrees)
     18
     19  Third is about the sign. It can be one of the following:
     20  - positive is clockwise (this is the default for degrees)
     21  - positive is counterclockwise (this is the default for radian and 65536)
     22
     23  TBGRAPath and TBGRACanvas2D follow HTML5 convention which is:
     24    (radian, right-most, clockwise) that can be shortened to (radian, clockwise)
     25    because right-most is the default for radian. This is abbreviated as "radCW".
     26
     27  When radian are CCW, it is also specified in order to make it clear, even
     28  if it is the default convention in mathematics.
     29
     30  In order to make things easier, there are some functions that accept angles
     31  in degrees. The convention used here is the usual degree convention:
     32    (degrees, top-most, clockwise) that can be shortened to (degree)
     33    because top-most and clockwise is the default for degrees.

    10   SimpleStretch does a fast stretch by splitting the image into zones defined
    11   by integers. This can be quite ugly.
     10  SimpleStretch does a boxed resample with limited antialiasing.
    1211
    1312  FineResample uses floating point coordinates to get an antialiased resample.

     6  Font rendering units : BGRAText, BGRATextFX, BGRAVectorize, BGRAFreeType
     7
     8  This unit provide text effects. The simplest way to render effects is to use TBGRATextEffectFontRenderer class.
     9  To do this, create an instance of this class and assign it to a TBGRABitmap.FontRenderer property. Now functions
     10  to draw text like TBGRABitmap.TextOut will use the chosen renderer. To set the effects, keep a variable containing
     11  the TBGRATextEffectFontRenderer class and modify ShadowVisible and other effects parameters.
     12
     13  The TBGRATextEffectFontRenderer class makes use of other classes depending on the situation. For example,
     14  TBGRATextEffect, which is also in this unit, provides effects on a text mask. But the renderer also uses
     15  BGRAVectorize unit in order to have big texts or to rotate them at will.
     16
     17  Note that you may need TBGRATextEffect if you want to have more control over text effects, especially
     18  if you always draw the same text. Keeping the same TBGRATextEffect object will avoid creating the text
     19  mask over and over again.
     20
     21  TextShadow function is a simple function to compute an image containing a text with shadow.

     8  Font rendering units : BGRAText, BGRATextFX, BGRAVectorize, BGRAFreeType
     9
     10  This unit provides vectorizers :
     11  - VectorizeMonochrome function vectorizes a back'n'white image
     12  - TBGRAVectorizedFont allows to vectorize and to load vectorized font and draw them
     13
     14  TBGRAVectorizedFontRenderer class works like other font renderers, i.e., it can
     15  be assigned to the FontRenderer property. You can use it in two different modes :
     16  - if you supply a directory, it will look for *.glyphs files in it to load fonts
     17  - if you don't supply a directory, fonts will be vectorized from LCL
     18
     19  Note that unless you want to supply your own glyphs files, you don't need
     20  to use explicitely this renderer, because TBGRATextEffectFontRenderer will
     21  make use of it if necessary, according to effects parameters used.
