DirectDrawGraphicsMBS.ClearStrokeStyle

If no stroke style is defined, a default one is used.

DirectDrawGraphicsMBS.Constructor(Graphics as Graphics)

dim p as new Picture(200,200)
dim g as Graphics = p.Graphics
// Clear image with white
g.DrawingColor = &cFFFFFF
g.FillRectangle 0, 0, g.Width, g.Height

dim d as new DirectDrawGraphicsMBS(g)

call d.CreateSolidColorBrush(&cFF0000)
d.DrawLine 10, 10, 190,190

Backdrop = p

Pass the graphics in a paint event or from a picture.

Requires Xojo 2019r2 or newer.

DirectDrawGraphicsMBS.CreateSolidColorBrush(c as Color) as Boolean

dim d as new DirectDrawGraphicsMBS(g)

// make full blue with no alpha
call d.CreateSolidColorBrush(&c0000FFFF)

Pass the red, green, blue, and alpha values of the brush's color as a Xojo color.

See also:

• CreateSolidColorBrush(red as Single, green as Single, blue as Single, alpha as Single = 1.0) as Boolean

Some examples using this method:

• /Win/DirectDraw Line Drawing

DirectDrawGraphicsMBS.CreateSolidColorBrush(red as Single, green as Single, blue as Single, alpha as Single = 1.0) as Boolean

Pass the red, green, blue, and alpha values of the brush's color.
Range of values is from 0.0 to 1.0.

• CreateSolidColorBrush(c as Color) as Boolean

DirectDrawGraphicsMBS.CreateStrokeStyle(startCap as Integer = 0, endCap as Integer = 0, dashCap as Integer = 0, lineJoin as Integer = 0, miterLimit as Single = 1.0, dashStyle as Integer = 0, dashOffset as Single = 0, Dashes() as Single = nil) as Boolean

Creates and sets the stroke style. Returns true on success and false on failure.

startCap	The cap applied to the start of all the open figures in a stroked geometry.
endCap	The cap applied to the end of all the open figures in a stroked geometry.
dashCap	The shape at either end of each dash segment.
lineJoin	A value that describes how segments are joined. This value is ignored for a vertex if the segment flags specify that the segment should have a smooth join.
miterLimit	The limit of the thickness of the join on a mitered corner. This value is always treated as though it is greater than or equal to 1.0.
dashStyle	A value that specifies whether the stroke has a dash pattern and, if so, the dash style.
dashOffset	A value that specifies an offset in the dash sequence. A positive dash offset value shifts the dash pattern, in units of stroke width, toward the start of the stroked geometry. A negative dash offset value shifts the dash pattern, in units of stroke width, toward the end of the stroked geometry.
Dashes	An array whose elements are set to the length of each dash and space in the dash pattern. The first element sets the length of a dash, the second element sets the length of a space, the third element sets the length of a dash, and so on. The length of each dash and space in the dash pattern is the product of the element value in the array and the stroke width.

DirectDrawGraphicsMBS.GetTransform(byref m11 as Single, byref m12 as Single, byref m21 as Single, byref m22 as Single, byref dx as Single, byref dy as Single)

DirectDrawGraphicsMBS.RestoreDrawingState

Our plugin manages the stack of drawing states saved.
We raise an exception if your calls to restore are not balanced with save.

DirectDrawGraphicsMBS.SaveDrawingState

Our plugin manages the stack of drawing states saved, so you can restore them later.

DirectDrawGraphicsMBS.SetTransform(m11 as Single, m12 as Single, m21 as Single, m22 as Single, dx as Single, dy as Single)

All subsequent drawing operations occur in the transformed space.
