IMO, you have two solutions: a) Use the new, but experimental, Delphi-OpenCV-Class (opencv 4.5.5) for Delphi 10.4 & 11.0 package: https://github.com/Laex/Delphi-OpenCV-Class Laex is doing a very very good job to import opencv 4.5.5 C++ based DLLs to Delphi. I don't know how much of opencv is already ported but I've cloned the project only yesterday and tried a basic Canny function: Works very very fastly, with native Delphi (in the snapshot I've got frames from a USB camera and applied canny filter). During run-in IDE environment there are some delays (also in Release) because uses debug versions of DLLs, but when you close the IDE and start the program from Explorer BOOM is a rocket. I will move, only in the next future, my Python delphivcl application to be a native Delphi set of classes. This ONLY to fully integrate into Forms of native VCL program. b) To back processed image to Delphi just pass the opencv NumPy array content which can be o monodimensional array for gray images or a tridimensional array for images with RGB. Pass also Width and Height info. Then you have only to use a Bitmap, and related canvas HDC Handle with the same width and height and use DIB windows functions to recreate bitmap image from a byte array. This is an extract of yesterday's experiments for upon Image. TMat is the Laex generics implementation of OpenCV mat so array of bytes of image: function MatDraw(DC: HDC; Image: TMat; const Rect: TRect; const Stretch: Boolean = True): Boolean; type pCOLORREF = ^COLORREF; pBITMAPINFOHEADER = ^BITMAPINFOHEADER; var // isrgb: Boolean; IsGray: Boolean; buf: array [1 .. SizeOf(BITMAPINFOHEADER) + SizeOf(RGBQUAD) * 256] of byte; dibhdr: pBITMAPINFOHEADER; _dibhdr: TBitmapInfo ABSOLUTE buf; _rgb: pCOLORREF; i: Integer; iResult: Integer; begin if Image.empty then Exit(False); // isrgb := ('R' = upcase(img^.colorModel[0])) and ('G' = upcase(img^.colorModel[1])) and ('B' = upcase(img^.colorModel[2])); // isgray := 'G' = upcase(img^.colorModel[0]); IsGray := Image.channels = 1; // if (not isgray) and (not isrgb) then // Exit(false); // if (1 = img^.nChannels) and (not isgray) then // Exit(false); dibhdr := pBITMAPINFOHEADER(@buf); _rgb := pCOLORREF(Integer(dibhdr) + SizeOf(BITMAPINFOHEADER)); if (IsGray) then for i := 0 to 255 do _rgb[i] := rgb(i, i, i); dibhdr^.biSize := SizeOf(BITMAPINFOHEADER); dibhdr^.biWidth := Image.cols; // Check origin for display // if img^.Origin = 0 then dibhdr^.biHeight := -Image.rows; // else // dibhdr^.biHeight := img^.Height; dibhdr^.biPlanes := 1; dibhdr^.biBitCount := 8 * Image.channels; dibhdr^.biCompression := BI_RGB; dibhdr^.biSizeImage := 0; // img^.imageSize; dibhdr^.biXPelsPerMeter := 0; dibhdr^.biYPelsPerMeter := 0; dibhdr^.biClrUsed := 0; dibhdr^.biClrImportant := 0; if Stretch then begin SetStretchBltMode(DC, COLORONCOLOR); SetMapMode(DC, MM_TEXT); // Stretch the image to fit the rectangle iResult := StretchDIBits(DC, Rect.Left, Rect.Top, Rect.Width, Rect.Height, 0, 0, Image.cols, Image.rows, Image.Data, _dibhdr, DIB_RGB_COLORS, SRCCOPY); Result := (iResult > 0); // and (iResult <> GDI_ERROR); end else begin // Draw without scaling iResult := SetDIBitsToDevice(DC, Rect.Left, Rect.Top, Image.cols, Image.rows, 0, 0, 0, Image.rows, Image.Data, _dibhdr, DIB_RGB_COLORS); Result := (iResult > 0); // and (iResult <> GDI_ERROR); end; end; Code went from Laex library sources so try to read them.

Hi, all I'm trying to use Python extension from Embarcadero: https://github.com/Embarcadero/DelphiVCL4Python installed in Python 3.9 (32 bits) with pip install delphivcl I was able to assign an

I'm not used with github fork/push/request of pull but I've open a pull request: https://github.com/Embarcadero/python4delphi/pull/25 I hope it is the right way to do...

Hi all. There is a way to detect if compile phase is in Delphi 10.4.1 or 10.4.2 ? At Embarcadero documentation they notice only VER340 and compiler 34.0 for either: https://docwiki.embarcadero.com/RADStudio/Alexandria/en/Compiler_Versions but VCL from 10.4.1 and 10.4.2 is different and in 10.4.1 NumberBox is not available. This block 10.4.1 users to compile PythonVCL design package or force them, at any pull, to manually remove any reference to NumberBox where present in check: {$IFDEF DELPHI10_4_OR_HIGHER} ... {$ENDIF DELPHI10_4_OR_HIGHER}.

Initially failed to understand how in Demo29 the use of PIL allowed to place an image in a TImage object. But slowly I succeeded: rgb_im = PIL_Image.fromarray(np.uint8(frame)).convert('RGB') self.imgFrameI.Picture.Bitmap.SetSize(rgb_im.width, rgb_im.height) dib = PIL_ImageWin.Dib(rgb_im) dib.expose(self.imgFrameI.Picture.Bitmap.Canvas.Handle) self.imgFrameI.Repaint() rgb_im = PIL_Image.fromarray(np.uint8(frame_out)).convert('RGB') self.imgFrameO.Picture.Bitmap.SetSize(rgb_im.width, rgb_im.height) dib = PIL_ImageWin.Dib(rgb_im) dib.expose(self.imgFrameO.Picture.Bitmap.Canvas.Handle) self.imgFrameO.Repaint() Now perfectly works and from 30FPS of PySimpleGUI version, I've reached 89 stable FPS with delphivcl version. AMAZING how fast delphi vcl is"

I'm converting a complex Python PySimpleGUI based program to Python using delphivcl module. In my initial test, the gained speed on UI things sees delphivcl as a very winner. But I need to add some missing features in delphivcl controls as well as the possibility to modify an Image (TImage) content sending it as an array of bitmap (NumPy arrays) instead to have to create a file.bmp and then load it with Image.Picture.LoadFromFile. Also, I need to add OnMouseDown/OnMouseUp in buttons. Gitting delphivcl, or delphifmx, I was not able to find the delphi building project, only the final files. Where I can find sources and projects to make delphivcl module and so to add new features?

Thanks for the info. I remember your suggestion to report the request in github in the issue department. I haven't done it yet because first I would like to try to do something myself, both because I started studying P4D sources and making some modules, and to actually understand how many things are necessary to cover my needs and that they are then useful to everyone. . The project I'm converting from PySimpleGUI is a real-time object recognition system that uses OpenCV and other AI technologies with complicated UIs that need to be really fast, hence the choice of switching to DelphiVCL and / or DelphiFMX. Thanks again for the support.

GetIt is a very useful tool, just a click to install, but if you want to be always on the piece and aligned to the latest changes is better to work directly with sources in github.

I have not yet found a fast way to load TImage contents starting from a NumPy array... this method is enough fast BUT require a file support (at 30FPS SSD will suffer a lot): # gets and shows frame image storing it in a support file bmp_image = cv2.imencode('.bmp', frame)[1].tobytes() stream = BytesIO(bmp_image) with open("f:\output_a.bmp", "wb") as f: f.write(stream.getbuffer()) f.close() self.imgFrameI.Picture.LoadFromFile("f:\output_a.bmp") this method access to TImage canvas but is VERY SLOW: self.imgFrameI.Picture.Bitmap.SetSize(640, 480) canvas = self.imgFrameI.Picture.Bitmap.Canvas rgb_im = PIL_Image.fromarray(frame) for x in range(640): for y in range(480): b, g, r = rgb_im.getpixel((x, y)) rgb = b * 65536 + g * 256 + r canvas.SetPixel(x, y, rgb) There is some other way to set Picture of a Image() object from a image array ?

I was not able to update image content directly from data in memory, but only passing from a support file: def __on_timer_update(self, sender): # gets frame frame = cvc.video_capture_get_frame() bmp_image = cv2.imencode('.bmp', frame)[1].tobytes() # shows frame image storing it in a support file stream = BytesIO(bmp_image) with open("output.bmp", "wb") as f: f.write(stream.getbuffer()) f.close() self.imgFrame.Picture.LoadFromFile("output.bmp") This works but I would like to avoid working with files because 60 FPS are dangerous for SSD devices. There is some other way to assign the image, in this case a BMP to be simple, directly to an Image() object using python + DelphiVCL library module ?

Hi all. I'm trying to create a Python Extension Module with Delphi Sydney. I'm adding an IPC Engine Client to access to one or more IPC Engine Server (either based on Windows Messages). It works and is very a good tool. I've only a question about the resulting python class that does not have a list of properties/methods, not in all cases. Looking at xxx.__dir__ I can get the list of available methods: But if I use the code completion of PyScripter only base TPyDelphiPersistent are available: Strangely if I create a pre-made istance TPyIPCEngineClient object and I add it to the module as SetVar('myIPC', xxxx, xxx) all TPyIPCEngineClient are showed. What I'm mistaking ? Thank you in advance for replies. pycncipc1.zip

My preferred: Image32 SynEdit GLScene

The hard thing with a new environment, eg: Sydney vs Alexandria, is to move all 3rd parties libraries (often to re-buy), but overall learn workaround on always present IDE issues. The time to discover a problem with an IDE and tool-chain and learn the right workarounds to continue to work is a long activity. Back from new created file project to old, in case of very critical issues are a very waste of time.

@pyscripter I will do it surely! I'm trying initially to use the tools as they are. In the second phase, I will try to put my hands on it!

Hi all. I'm new to JSON frameworks and I'm getting lost in a spoonful of water. In the Sydney help I've found this code: JSONValue := TJSONObject.ParseJSONValue('{"colors":[{"name":"red", "hex":"#f00"}]}'); Memo1.Lines.Add('READER:'); if JSONValue is TJSONArray then //... else if JSONVAlue is TJSONObject then Memo1.Lines.Add('colors'); Memo1.Lines.Add('name: '+ JSONValue.GetValue<string>('colors[0].name')); Memo1.Lines.Add('hex: '+ JSONValue.GetValue<string>('colors[0].hex')); Now this works fine but I need to read a client request so formatted: var Text: string; Command: string; JsonValue: TJSONValue; JsonValueArg: TJSONValue; begin // parse json JSONValue := TJSONObject.ParseJSONValue('{"cmd":"program.add.text", "txt":"for I := 0 to 100 do"}'); if not (JSONValue is TJSONObject) then Exit; // gets command type (in Command I've found the "cmd" value "program.add.text". ALL RIGHT!!!) if JSONValue.TryGetValue('cmd', Command) then Exit; // gets command argument txt (does not found the "txt" value and program EXITS!!!) if JSONValue.TryGetValue('txt', Text) then Exit; //... I can't change the JSON request string to contain an array as well as in the Embarcardero sample because reach from a customer program and I've checked with only JSON validator and seem to be fine. What was I've mistaken? Thank you in advance for your replies.

I'm not aware of that, I'm an occasional user of Indy classes. So on TIdTTCPServerContex.Execute is better do not manage exceptions on WriteLn because are correctly managed in TidTCPServer.Execute caller? To be honest I've got some issues during close application when I do TIdTCPServer.Active := False and TIdTCPServer.Free; with connected clients... Could be because I catch the exceptions on Execute().... and the caller doesn't manage the right closing states. I've changed to: procedure TIPCTCPServerContext.Execute; type TRequestType = ( rqtpCmd, rqtpGet, rqtpSet ); var ArgS: string; ArgI: Integer; Command: string; Request: string; Response: string; JsonValue: TJSONValue; RequestType: TRequestType; begin // sets default response Response := RES_NULL; // extracts request from tcp stack Request := Trim(Connection.IOHandler.ReadLn); try // gets request type JSONValue := TJSONObject.ParseJSONValue(Request); try if not (JSONValue is TJSONObject) then Exit; while True do begin if JSONValue.TryGetValue(REQ_CMD, Command) then begin RequestType := rqtpCmd; Break; end; if JSONValue.TryGetValue(REQ_GET, Command) then begin RequestType := rqtpGet; Break; end; if JSONValue.TryGetValue(REQ_SET, Command) then begin RequestType := rqtpSet; Break; end; Exit; end; // evaluates request type case RequestType of rqtpCmd: begin if Command = 'cnc.homing' then begin if not JSONValue.TryGetValue<Integer>('["axes.mask"]', ArgI) then Exit; Response := DoCmdCNCHoming(ArgI); end else if Command = 'cnc.mdi.command' then begin if not JSONValue.TryGetValue('command', ArgS) then Exit; Response := DoCmdCNCMDICommand(ArgS); end else if Command = 'cnc.pause' then Response := DoCmdCNCPause else if Command = 'cnc.resume.after.pause' then Response := DoCmdCNCResumeAfterPause else if Command = 'cnc.resume.after.stop' then begin if JSONValue.TryGetValue<Integer>('line', ArgI) then Response := DoCmdCNCResumeAfterStop(ArgI) else Response := DoCmdCNCResumeAfterStop(0); end else if Command = 'cnc.start' then begin if JSONValue.TryGetValue<Integer>('line', ArgI) then Response := DoCmdCNCStart(ArgI) else Response := DoCmdCNCStart(0); end else if Command = 'cnc.stop' then Response := DoCmdCNCStop else if Command = 'program.analysis' then begin if JSONValue.TryGetValue('mode', ArgS) then Response := DoCmdProgramAnalysis(ArgS) else Response := DoCmdProgramAnalysis(''); end else if Command = 'program.analysis.abort' then Response := DoCmdProgramAnalysisAbort else if Command = 'program.gcode.add.text' then begin if not JSONValue.TryGetValue('text', ArgS) then Exit; Response := DoCmdProgramGCodeAddText(ArgS); end else if Command = 'program.gcode.clear' then Response := DoCmdProgramGCodeClear else if Command = 'program.gcode.set.text' then begin if not JSONValue.TryGetValue('text', ArgS) then Exit; Response := DoCmdProgramGCodeSetText(ArgS); end else if Command = 'program.load' then begin if not JSONValue.TryGetValue('name', ArgS) then Exit; Response := DoCmdProgramLoad(ArgS); end else if Command = 'program.new' then Response := DoCmdProgramNew else if Command = 'program.save' then begin if JSONValue.TryGetValue('name', ArgS) then Response := DoCmdProgramSave(ArgS) else Response := DoCmdProgramSave('') end else Exit; end; rqtpGet: begin if Command = 'axes.info' then Response := DoGetAxesInfo else if Command = 'cnc.info' then Response := DoGetCNCInfo else if Command = 'compile.info' then Response := DoGetCompileInfo else if Command = 'system.info' then Response := DoGetSystemInfo else Exit; end; rqtpSet: begin //## end; end; finally JSONValue.Free; end; finally Connection.IOHandler.WriteLn(Response); end; end; Should be more right now...

Yes Remy, I've made procedure TIPCTCPServerContext.Execute; type TRequestType = ( rqtpCmd, rqtpGet, rqtpSet ); var ArgS: string; ArgI: Integer; Command: string; Request: string; Response: string; JsonValue: TJSONValue; RequestType: TRequestType; begin try // sets default response Response := RES_NULL; // extracts request from tcp stack Request := Trim(Connection.IOHandler.ReadLn); // gets request type JSONValue := TJSONObject.ParseJSONValue(Request); try if not (JSONValue is TJSONObject) then AbortFast; while True do begin if JSONValue.TryGetValue(REQ_CMD, Command) then begin RequestType := rqtpCmd; Break; end; if JSONValue.TryGetValue(REQ_GET, Command) then begin RequestType := rqtpGet; Break; end; if JSONValue.TryGetValue(REQ_SET, Command) then begin RequestType := rqtpSet; Break; end; AbortFast; end; // evaluates request type case RequestType of rqtpCmd: begin if Command = 'cnc.homing' then begin if not JSONValue.TryGetValue<Integer>('["axes.mask"]', ArgI) then AbortFast; Response := DoCmdCNCHoming(ArgI); end else if Command = 'cnc.mdi.command' then begin if not JSONValue.TryGetValue('command', ArgS) then AbortFast; Response := DoCmdCNCMDICommand(ArgS); end else if Command = 'cnc.pause' then Response := DoCmdCNCPause else if Command = 'cnc.resume.after.pause' then Response := DoCmdCNCResumeAfterPause else if Command = 'cnc.resume.after.stop' then begin if JSONValue.TryGetValue<Integer>('line', ArgI) then Response := DoCmdCNCResumeAfterStop(ArgI) else Response := DoCmdCNCResumeAfterStop(0); end else if Command = 'cnc.start' then begin if JSONValue.TryGetValue<Integer>('line', ArgI) then Response := DoCmdCNCStart(ArgI) else Response := DoCmdCNCStart(0); end else if Command = 'cnc.stop' then Response := DoCmdCNCStop else if Command = 'program.analysis' then begin if JSONValue.TryGetValue('mode', ArgS) then Response := DoCmdProgramAnalysis(ArgS) else Response := DoCmdProgramAnalysis(''); end else if Command = 'program.analysis.abort' then Response := DoCmdProgramAnalysisAbort else if Command = 'program.gcode.add.text' then begin if not JSONValue.TryGetValue('text', ArgS) then AbortFast; Response := DoCmdProgramGCodeAddText(ArgS); end else if Command = 'program.gcode.clear' then Response := DoCmdProgramGCodeClear else if Command = 'program.gcode.set.text' then begin if not JSONValue.TryGetValue('text', ArgS) then AbortFast; Response := DoCmdProgramGCodeSetText(ArgS); end else if Command = 'program.load' then begin if not JSONValue.TryGetValue('name', ArgS) then AbortFast; Response := DoCmdProgramLoad(ArgS); end else if Command = 'program.new' then Response := DoCmdProgramNew else if Command = 'program.save' then begin if JSONValue.TryGetValue('name', ArgS) then Response := DoCmdProgramSave(ArgS) else Response := DoCmdProgramSave('') end else AbortFast; end; rqtpGet: begin if Command = 'system.info' then Response := DoGetSystemInfo else if Command = 'axes.info' then Response := DoGetAxesInfo else AbortFast; end; rqtpSet: begin //## end; end; finally JSONValue.Free; end; // sends response as json contents Connection.IOHandler.WriteLn(Response); except try Connection.IOHandler.WriteLn(Response) except end; end; end;

Hi all, I'm trying to use TTask to perform some parallel code with Sydney 10.4.1 looking at the sample code in Help System, so it should be supported by 10.4.1: but I've got always the error: [dcc32 Error] osIPCTCPServerContext.pas(423): E2250 There is no overloaded version of 'Create' that can be called with these arguments Have you any idea about it? Thank you in advance for replies.

Works perfectly !!! The only issue is on Delphi LSP which seems unable to elaborate pascal code for anonymous procedures on TTask( proc or TThread.Synchronize( Self, proc..,

Same of mine:

WOW compile but IDE signs as error. Perhaps is a bug in LSP...

You are RIGHT !!! Very sorry for this typo....

In a project file usually, I add that: // checks if application is already running AppplicationID := '{BFA11B69-B59C-40BA-BABB-724F2BF3AFE4}'; RunOnceMutex := CreateMutex(nil, True, @ApplicationID[1]); if RunOnceMutex <> 0 then begin if GetLastError = ERROR_ALREADY_EXISTS then begin ShowErrorMessage ( _('Application already running'), _('Press OK button to quit application'), _('Instance of this application is already running !'), _('For each computer, or virtual machine, is allowed to start a single instance of the Control Software. ' + 'If you see this message it means that an application instance is already loaded and running.') ); CloseHandle(RunOnceMutex); Halt; end end; Take care to create a different UUID for every singleton application. You can fastly create a new UUID pressing CTRL + SHIFT + G in Delphi IDE.

There is also a WMI Delphi Code Generator in which you can brose the interesting data and it creates code for you: https://github.com/RRUZ/wmi-delphi-code-creator

I will try surely! Thank you again. Python extension and support on our products were strong requirements from customers. Happy to know how simple is to do with py4d.
