ImageLab is a native Windows-based multi-sensor imaging tool for processing and analyzing hyperspectral images built in Delphi. It targets research in science and technology where spectrally resolved images are utilized. According to the developer “ImageLab provides multi-sensor support for hyperspectral imaging. This enables researchers to extract information from spectrally resolved images which cannot be obtained otherwise. ImageLab supports a long list of spectroscopic methods (i.e. uvvis, infrared, Raman, energy dispersive xray, THz, mass spectroscopy, and more) and is used in a broad range of applications (e.g. detecting particles in air, scanning tissue for cancer cells, uncovering ultrafine cracks in steel and more). Despite the sheer size of the application (approx. 750,000 lines of Delphi code) this new and unique application has been developed within 5 years from scratch (thanks to RAD Studio and the SDL Component Suite).” Website http://www.imagelab.at/ Screenshot Gallery Reduce development time and get to market faster with RAD Studio, Delphi, or C++Builder.

Earlier in the Python4Delphi Demo 3 post, we have learned how to create a Python Delphi Variable using the TPythonDelphiVar component, assign some value to it, and showed the value as a string. You can also use Python4Delphi with C++Builder. This post will see some advanced usage of the TPythonDelphiVar component. You can also use Python4Delphi with C++Builder. Python4Delphi Demo4 Sample App shows how to assign a variable value between Delphi and Python using the TPythonDelphiVar component events. This can be achieved by events that set and gets data as a variant or python object. Internally this component converts a value from Delphi to python and vice versa. You can find the Demo4 source on GitHub. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi. Components used in Python4Delphi Demo4 Sample App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a singleton class. TPythonGUIInputOutput: Inherited from TPythonInputOutput (which works as a console for python outputs) Using this component Output property you can associate the Memo component to show the Output. TPythonDelphiVar: Inherited from TEngineClient, used to convert the python variable to the Delphi variable and vice versa. It has methods to set and get value as variant or PyObject. It contains property like Module(TPythonModule internally created by default) where the python variable(TPyVar) is created and later converted to and from the Delphi variant or PyObject. TMemo: A multiline text editing control, providing text scrolling. The text in the memo control can be edited as a whole or line by line. You can find the Python4Delphi Demo4 sample project from the extracted repository ..Python4DelphiDemosDemo04.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property. It Is assigned with InitScript which import sys module and prints the Python.Dll version, copyright information to Memo2. import sys print(“Python Dll: “, sys.version) print(sys.copyright) print() PythonGUIInputOutput1 provides a conduit for routing input and output between the Graphical User Interface (GUI) and the currentlyexecuting Python script. PythonDelphiVar1 component is intended for demonstrating how to assign value between Delphi(Edit1.Text)->Python Delphi variable(test.Value) and back from (test.Value) -> Edit1.Text using event PythonDelphiVar1GetData and PythonDelphiVar1SetData respectively. The data is passed as variant type here. procedure TForm1.PythonDelphiVar1GetData(Sender: TObject; var Data: Variant); begin Data := Edit1.Text; end; procedure TForm1.PythonDelphiVar1SetData(Sender: TObject; Data: Variant); begin Edit1.Text := Data; end; procedure TForm1.PythonDelphiVar1GetData(Sender: TObject;   var Data: Variant); begin   Data := Edit1.Text; end; procedure TForm1.PythonDelphiVar1SetData(Sender: TObject; Data: Variant); begin   Edit1.Text := Data; end; PythonDelphiVar2 component is intended for demonstrating how to get and set python objects using PythonDelphiVar2ExtGetData and PythonDelphiVar2ExtSetData events. A python object is created using the python script and assigned to PythonDelphiVar2 value. class C:   def __init__(Self, Arg):     Self.Arg = Arg   def __str__(Self):     return “

Xinorbis is a very powerful hard disk, folder and storage analyzer available over on SourceForge. A good portion of it is open source and mainly written in Delphi. Other utilities included with it are written in C++ and C# which shows how easy it is into integrate Delphi and Object Pascal with other languages. According to the website “It uses a sophisticated mix of graphs, tables, and tree displays to give a complete, and unprecedented, picture of the contents of any hard disk, SSD, folder, removable or network drive. In fact, if your PC can see it, Xinorbis can scan it. Xinorbis makes it easy to see the contents, structure, file distribution, and file composition of any attached storage device. It includes fully customizable report generation in ASCII, CSV, HTML and XML.” As you can see it uses a Delphi style to implement a dark theme.

As we know, a Variable stores a value so that you can reuse it later in your program. This reduces redundancy, improves performance, and makes your code more readable. What is Python Delphi Variable? This post will guide you to understand. You can also use Python4Delphi with C++Builder. Python4Delphi Demo3 Sample App shows how to create a Python Delphi Variable in Delphi using the TPythonDelphiVar component(convert the python variable to the Delphi variable and vice versa), shows the variable type and the value assigned to it, reassign different type value to the same variable, show the variable content in a message. You can find the Demo3 source on GitHub. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi. Check Demo1 and Demo2 which covers how to run a python script and evaluate an expression in Delphi. Components used in Python4Delphi Demo3 Sample App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a Singleton Class. TPythonGUIInputOutput: Inherited from TPythonInputOutput (which works as a console for python outputs) Using this component Output property you can associate the Memo component to show the Output. TPythonDelphiVar: Inherited from TEngineClient, used to convert the python variable to the Delphi variable and vice versa. It has methods to set and get value as variant or PyObject. It contains property like Module(TPythonModule internally created by default) where the python variable(TPyVar) is created and later converted to and from the Delphi variant. TMemo: A multiline text editing control, providing text scrolling. The text in the memo control can be edited as a whole or line by line. You can find the Python4Delphi Demo3 sample project from the extracted GitHub repository ..Python4DelphiDemosDemo03.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property.

In Python, variables need not be declared or defined in advance, as is the case in Delphi. To create a variable, you just assign it a value and then start using it. A variable may be assigned a value of one type and then later re-assigned a value of a different type. PythonDelphiVar1 created with the name ‘test’. This variable is used in the Memo1 default python script, which is assigned with the value 10, and print the value to the Memo2. Later the same variable is reassigned with value [1,2,3] and print the value. The script used is as follows, test.Value = 10 print(test, test.Value) test.Value = [1,2,3] print(test)Here the variable is created for Module ‘__main__’. Memo1 used for providing the Python Script and Memo2 for showing the output. Buttons to perform the execution, load script from, save the script to a file, show variable content to a message. On Clicking Execute Button the python script is executed using the below code. PythonEngine1.ExecStrings( Memo1.Lines ); PythonEngine1.ExecStrings( Memo1.Lines ); Load the custom script to the Memo1 from a […]

Developer Tore Ottinsen had this to say about his app Orbit Xplorer “I am a retired high school physics teacher and a hobby Delphi programmer. This is my latest physics app, written in FMX for Windows. Hoping to do a Mac version soon.” It’s a good example of how accessible Delphi is as an IDE and Object Pascal as a programming language. According to the website “Orbit Xplorer is an easy-to-use orbit simulator suitable for high school, college and university students and teachers, or anyone with an interest in physics and astronomy. For the first time you can do “lab exercises” in gravitational physics! If you are solving problems involving orbits of satellites, planets or stars it will be exciting to simulate the problem in Orbit Xplorer and compare its numerical output with your own solutions.” Orbit Xplorer makes use of FireMonkey and a good number of FireMonkey styles.
