Does anyone have a hint or explanation for the following problem ? I draw a path with a bitmapshader. When canvas is not scaled, it looks good ( first picture ). When I scale into ( zooming in ) the bitmapshader is not be scaled and looks very ugly. I tried several things with recreating the bitmapshader after zooming in, but did not succeed :-(. Does anyone have a hint ? No Scaling it looks good : when scaling it looks ugly: Code : canvas.scale(scalex, scaley); canvas.translate(itranslatex, itranslatey); fillBMP = makePatternCross(fscalex, 1, Color.GREEN/*,fscalex,fscaley*/); fillBMPshader = new BitmapShader(fillBMP, BitmapShader.TileMode.REPEAT, BitmapShader.TileMode.REPEAT); paintshader = new Paint(); paintshader.setShader(fillBMPshader); canvas.drawPath(cpath.path, paintshader); private static Bitmap makePatternCross(float fSize, float fStrokewith,int iColor) { Log.v("Create Patter makePatternCross","makePatternCross"); float fBitmapSizeOrig = 10; fBitmapSizeOrig=fBitmapSizeOrig*fSize; Bitmap bm = Bitmap.createBitmap((int)fBitmapSizeOrig,(int) fBitmapSizeOrig,Bitmap.Config.ARGB_8888); Canvas c = new Canvas(bm); //c.scale(200, 200); c.drawColor(Color.WHITE); Paint p = new Paint(); p.setColor(iColor); //p.setStrokeWidth(iStrokewith); p.setStrokeWidth(fStrokewith/fSize); p.setStrokeWidth((float) 0.000001); c.drawLine(0, 0, fBitmapSizeOrig, fBitmapSizeOrig, p); c.drawLine(0, fBitmapSizeOrig, fBitmapSizeOrig, 0, p); if (fSize != 1) { int iNewSize = (int) (( fBitmapSizeOrig) * fSize); bm = Bitmap.createScaledBitmap(bm, iNewSize, iNewSize, false); } int width = bm.getWidth(); int height = bm.getHeight(); for (int x = 0; x <
