For applications that use GDI+ and set the width of the pen object to zero (0), on monitors with higher dots per inch (DPI) or resolution, or applications that use scaling, you may encounter this problem. After we have a deeper understanding of the features of GDI+, we will immediately show you a list of solutions.
What does GDI+ do?
Graphics Device Interface (GDI) is a technology that allows Windows applications to provide what you see is what you get (WYSIWYG) functionality.
GDI+ is an improved version of the GDI graphics driver based on C++. GDI is an application programming interface and basic operating system component in Windows, responsible for representing graphical objects and transmitting them to output devices.
With the aid of the Graphical Device Interface Enhanced Edition (GDI+), application programmers can display information on the screen or printer without having to care about the specific functions of the display device.
In the application software, the programmer calls the methods provided by the GDI+ class, and then these methods make related calls to the appropriate device driver.
It also separates the program from the graphics hardware, and it is this separation that enables developers to build applications that do not rely on graphics hardware.
If inGDI+Windows error appears in the, what should I do?
1. Run SFC scan
- according to Windows + S Key to open the search bar, then type cmd, Then right click on the most relevant result to run it as an administrator.
- Type or paste the following command and press Enter:
sfc / scannow
Just wait for the process to complete (this may take some time), and then restart the computer to apply the changes. SFC will automatically find and restore damaged files and directories.
2. Run Power Troubleshooter
- according toWindows+IKey to openset upApplication, then navigate to the system in the left panel, then navigate from the right toTroubleshoot.
- After entering the troubleshooting menu, clickOther troubleshootingOptions.
- Now scroll down until you encounterpower supplyTroubleshooter and click Run next to it.
Once the troubleshooter finishes searching for the error, it will show you the exact error that occurred and how to fix it. Make sure to follow the instructions shown step by step.
3. Update the graphics card driver
- Right-click the Start icon, and then clickDevice Manager”Turn it on.
- Now expand the Display adapters section and right click on each option, then selectUpdate driver.
Wait for the process to complete, and then restart the computer to apply the changes. We strongly recommend that you use a dedicated tool to automatically update the driver, such as DriverFix.
4. Check for Windows Update
- according to Windows + I Key to open the Settings application, and then click in the left panelWindows update.
- If you have any new updates to download, click “Now Install” Button and wait for the process to complete, otherwise click the “Check for Updates” button.
If you are running an older version of Windows, this may be a factor causing the error, which can be corrected by updating the operating system. Most likely, the error will be resolved in a subsequent update of the software.
5. Start the computer with a clean boot
- according toWindows+RKey to open a new run box, then type or pastemsconfigAnd click OK.
- Navigate toBootTab and checkBoot optionsSafe boot option under.
- Now go to the tab that says “General” and make sure that “Selective start” Radio button, but uncheck “Load Startup Items” under it.
- Select the “Services” tab and select “ Hide all Serve“Box, and then click “Disable All” to disable all unnecessary services that may cause problems.
- On the Startup tab, click Open Task Manager”And disable all enabled startup items.
Now you can continue the restart process. Windows will do its work automatically, all you have to do is wait for the process to complete.
What is the difference between GDI+ and Direct2D?
Geometric figures such as polygons, ellipses, and lines are rendered using GDI in an opaque and aliased state. Through AlphaBlend API, it can render alias and ClearType text, and supports transparency blending.
However, its treatment of transparency is inconsistent, and most GDI APIs ignore the alpha channel.
Only a few GDI APIs can guarantee the content in the alpha channel after the operation. More importantly, the rendering performed by GDI cannot be converted into 3D operations well, and modern GPUs render the most effective on the 3D part of their rendering engine.
Examples include Direct2D’s aliased lines are designed to be simply implemented as two triangles displayed on the GPU, while GDI uses Bresenham’s line drawing method.
Direct2D renders primitives that are opaque, transparent, aliased, and anti-aliased. Transparency and dynamic effects are often used in modern user interfaces.
Due to strict guarantees, it provides how it accepts and generates transparent content, and the fact that all its primitives use hardware accelerated display, Direct2D makes it easy to develop modern user interfaces.
Direct2D is not a true superset of GDI, it does not include primitives, if they are implemented on the GPU, they will become unacceptable. Because the development of Direct2D places great emphasis on 3D acceleration, it is also very simple to use in combination with Direct3D.
