c# - Use Graphic.DrawLines(Pen pen, Points points) for Metafile, the picture cannot open when the count of points is large -


I have a problem with GDI + metafile. I want to save a metafile by graphic. It works well when the point number is 10000 and the saved metafile can be opened. But when the point number is large (eg calculation = 10000000), the metafile can not be opened by mspaint.exe.

Do not I miss anything? Is metafile record size limited? By the way, this problem is also in DraculaGallales .

This is my code: 

  Private Zero Button 1_Click (Object Sender, EventArgs e) {Int width = 1489; Intensity height = 471; Graphics offscreen buffer graphics; Metaphil me; (Using memorystream stream = new memorystream ()) (offscreen buffer graphics = graphics.framhound internally (int.t.or.o)) {int pttrc consoletexhandle = offscreen buffer graphics. GATHDC (); M = new metafile (stream, device contex handle, new rectangle (0, 0, width, height), metafile frame unit pixel, iii. OffScreenBufferGraphics.ReleaseHdc (); }} (Graphics G = Graphics. Framesize (m)) {// Everything high quality g. SmoothingMode = Smoothing. G. Interpolation mode = Interpolation mode. Highquite bibbic; G.PixelOffsetMode = PixelOffsetMode.HighQuality; G.CompositingQuality = CompositingQuality.HighQuality; Metafile header metafile header = M. Gatemeta header (); G. Scale Transform (MetaFileHeader.dpiax / g.dpiax, MetaFileHeader.dpi / g.dpiI); G.PageUnit = GraphicsUnit.Pixel; G. Satclipp (new rectangle (0, 0, width, height)); // clears the image and colors the entire background. Clear (color white); Attract lines using pen pen (new pen (black, 1f)) {Random RD = new random (datetime.now.millisecond); & Lt; PointF & gt; PolyPoint = new list & lt; Pointf> (); Const int count = 10000; (Int i = 1; i

This seems like a limit if I use DrawLines Instead of using DrawPath , it works properly.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

file rename - Git : Not under version control fatal error -

I am trying to rename a file via the Torotoisegit -> Rename option. The file is already subject to version control because it was checked-in at the previous commit.

I have also tried to rename files through the "GIT MV" option, but I am still getting the same error.
