How to use GDIPLUS -> NewGradientBrush ?

[ukoenig]

Hello,

I wanted to add a gradient-sample using GDIPLUS
but no gradient is painted.

the defined brush

// NewGradientBrush( nTop, nLeft, nWidth, nHeight, nType,;
// nTrans1, nRed1, nGreen1, nBlue1,;
// nTrans2, nRed2, nGreen2, nBlue2 ) CLASS Brush
// nType : 1_> horizontal 2-> vertical 3->diagonal derecha 4-> diagonal izq
LOCAL oBrush := Brush():NewGradientBrush( 0, 0, 200, 200, 1,; // just the area / size
255, 131, 193, 193,;
255, 255, 255, 255 )

tested as well the same size -> 250, 300, 200, 200 from the defined area.

solid brush is working !

oBrush := Brush():NewSolidBrush( 255, 255, 128, 0 ) // Orange

and the defined area

oGraphics := Graphics():New( oWnd:hDC )
oPath := Path():new()
oPath:AddRoundRect( 250, 300, 200, 200, 50 )
oGraphics:FillPath( oBrush, oPath)
oGraphics:Destroy()

another test

oGraphics := Graphics():New( oWnd:hDC )
oGraphics:DrawRect( , oBrush, 250, 50, 200, 200 )
oGraphics:Destroy()

any idea ? ( maybe a working example )
I found nothing about it in the forum or sample-directory

regards
Uwe

This is a bug in class, please try and tell me
Now

Code: Select all  Expand view

METHOD NewGradientBrush( nTop, nLeft, nWidth, nHeight, nType,;

return Self

It is working now but the gradient-position is still missing

aGrad := { { nGradpos, nColorF, nColorB }, { nGradpos, nColorB, nColorF } } // 0.5 = centered

// position = 0
::hBrush = GdiPlusNewGradientBrush( nTop, nLeft, nWidth, nHeight, ;
nTrans1, nRed1, nGreen1, nBlue1,;
nTrans2, nRed2, nGreen2, nBlue2, nType )

We can define brushes for color and gradient

CLASS Brush
DATA hBrush

METHOD NewSolidBrush
METHOD NewGradientBrush

how to define something like

METHOD NewImageBrush

------------



The Bmp-brush is shown as a resized image not tiled
Image-test ( I noticed a little problem with top / left )

LOCAL oImage1 := GDIBmp():new( c_path1 + "Blustone.bmp" )
LOCAL oGraphics1 := Graphics():New( oWnd:hDC )
LOCAL oImage2 := GDIBmp():new( c_path1 + "Marble.bmp" )
LOCAL oGraphics2 := Graphics():New( oWnd:hDC )
LOCAL oGraphics3 := Graphics():New( oWnd:hDC )
LOCAL oGraphics4 := Graphics():New( oWnd:hDC )
LOCAL aRect := GETCLIENTRECT( oWnd:hWnd ), oPen1, oPen2

oGraphics1:DrawImage( oImage1, aRect[1] + 150, aRect[2] + 250, 200, 200 )
oGraphics1:destroy()
oPen1 := Pen():New( 255 , 255, 0 , 0 , .T.)
oPen1:Setsize(10)
oGraphics3:DrawRoundRect( oPen1, , aRect[2] + 250, aRect[1] + 150, 200, 200, 50 )

This code , would serve you ?

HB_FUNC( GDIPLUSNEWTEXTUREBRUSH )
{
Bitmap * newImage = ( Bitmap * ) hb_parptr( 1 );
hb_retptr( new TextureBrush( newImage ) );
}


METHOD NewTextureBrush( oGdiBmp ) CLASS Brush
::hBrush = GdiPlusNewTextureBrush( oGdiBmp:hbmp )
return Self

[ukoenig]

I added this solution to tgdiplus.prg for testing
but there are compilr-syntax-errors on

HB_FUNC( GDIPLUSNEWTEXTUREBRUSH )

Uwe

[nageswaragunupudi]

May I know what is it you want to achieve that is not possible now with the existing FWH builtin functions?

[mastintin]

HB_FUNC( GDIPLUSNEWTEXTUREBRUSH ) it has to be placed inside gdiplus.cpp file is cpp code .

[ukoenig]

Mr. Rao,

May I know what is it you want to achieve that is not possible
now with the existing FWH builtin functions?

There was no GDIPLUS-TEXTUREBRUSH- and GRADIENT - solution included in TGDIPLUS.
I*ve been looking for it to complete my tests.

____________

Trying to compile < GDIPLUS.cpp > I got problems and couldn't test
the suggested different solutions.
Maybe it is possible to include it in my defined make-file from above ?
to test texture-brushes and rounded images.



that works !
oBrush := Brush():NewSolidBrush( 255, 255, 128, 0 ) // Orange

needed
obrush must be a GDI-texture- or imagebrush to fill a rounded area

oGraphics := Graphics():New( oWnd:hDC )
oPath:AddRoundRect( aRect[2] + 700, aRect[1] + 150, ; // must be defined < Left / Top > normally Top / Left
oImage:GetWidth() * 0.5, oImage:GetHeight() * 0.5, 50 ) // resized to 50 %
oGraphics:FillPath( oBrush, oPath)
oGraphics:Destroy()

Uwe

[ukoenig]

Is it possible to add the new GDIPLUS-brush-defines to the next FWH-release ?
