[Solved with Solution]BackgroundWorker/Bitmap drawing slower on Dual Core? Or Widnows 7? pls help me...
Hello,
I finished my programm and wanted start the big test part.
Today I started it on a Windows 7 DualCore machine and my BackgroundWorker is damm slow now!
I coded it with a crappy old xp pc and everything works fine.
My computer just takes 3 to 4 seconds to render the image
The Widnows 7 PC took about 4-5 Minutes!!!
WTF?
Heres my Code:
My BackgroundWorker creates a virtual Bitmap and if it is finished the Bitmap becomes the PictureBox's Background.
private void paintInBackground_DoWork(object sender, DoWorkEventArgs e)
{
int w = 390 - 1, h = 390 - 1;
bitmap = new Bitmap(w, h, System.Drawing.Imaging.PixelFormat.Format64bppPArgb);
bmpgrafik = Graphics.FromImage(bitmap);
bmpgrafik.CompositingMode = CompositingMode.SourceCopy;
bmpgrafik.CompositingQuality = CompositingQuality.GammaCorrected;
painterflag = false; // Enthält ein Messwert eine Note unter 1 ist etwas schief gelaufen
Color notenfarbe = new Color();
try
{
if (measuredatas != null)
{
for (int k = 0; k < measuredatas[aktTab].Length && invisible_or_blasser == "blasser"; k++)// Bei der Angabe "blasser" werden die punkte mit einen niedrigeren A Wert
// angegeben. Dadurch ist dieser Punkt eben blasser
// Ist "unsichtbar" angegeben dann geht er erst gar nicht in diese schleife und lässt den Punkt aus
{
notenfarbe = choosemarkcolor(measuredatas[aktTab][k].Mark);
notenfarbe = Color.FromArgb(65, notenfarbe);
if (dottype == 0)
bmpgrafik.FillRectangle(new SolidBrush(notenfarbe), (int)measuredatas[aktTab][k].CoordX + w / 2 - dotstrength, (int)measuredatas[aktTab][k].CoordY * -1 + h / 2 - dotstrength, dotstrength * 2 + 1, dotstrength * 3 + 1);
else if (dottype == 1)
bmpgrafik.FillEllipse(new SolidBrush(notenfarbe), (int)measuredatas[aktTab][k].CoordX + w / 2 - dotstrength, (int)measuredatas[aktTab][k].CoordY * -1 + h / 2 - dotstrength, (dotstrength * 2 + 1), (dotstrength * 2 + 1));
