Board index » Visual Studio » CBrush(*CBitmap) Texture Brush Printing Issue.

Visual Studio323
Question is: What can I do to make sure that when printing in Landscape that

a CBrush (Texture Brush) will not overlap, but tile correctly as it does in

Portrait mode?



Here is the sample code:



//Temp Device COntext

CDC dcTemp;

CBitmap bmp;



//Create the Bitmap Texture (nScaleFactor is global)

bmp.CreateCompatibleBitmap(pDC,20*nScaleFactor,20*nScaleFactor);



//Create compatible DC

dcTemp.CreateCompatibleDC(pDC);



//Select the Bitmap into the temp DC

oldBMP = dcTemp.SelectObject(&bmp);



//Draw the Bitmap Texture

RECT rc;

CBrush brushWhite(RGB(255,255,255));

dcTemp.GetClipBox(&rc);



//Make the actual Texture pattern. In this case, just a circle

dcTemp.FillRect(&rc, &brushWhite);

dcTemp.Ellipse(&rc);

dcTemp.SelectObject(oldBMP);



//Create a Texture brush using the Bitmap above

CBrush brush4(&bmp);



//Select the Texture Brush in the current DC

pOldBrush = pDC->SelectObject(&brush4);



//Paint with Tecture bitmap (200X200 Square)

pDC->Rectangle(100*nScaleFactor,100*nScaleFactor,300*nScaleFactor,300*nScale

Factor);



This prints fine in "Portrait" mode, but in Landscape, the texture is not

tiled correctly. There is overlapping of the texture.

Please NOTE: 'nScaleFactor' is used to scale the draw such that it prints

the right size on the printer (is 1 when in running mode, and ranges from 2

to 8 when printing depending on the DPI of printer used)



This is adjusted in the OnPrint() Method:



//m_rcPaper is a CRect sized to a 8.5" X 11" paper (850,1100)

m_fZoomFactor = (float)pInfo->m_rectDraw.Width()/m_rcPaper.Width();



Thanks,

Joe

Joe,



Personally, I would have tiled the brush myself, but that's just me being a

control-freak. You might wat to experiment with the following (taken from

MSDN, UnrealizeObject in the SDK): UnrealizeObject, SetBrushOrgEx, and

SelectObject on the brush.
