Paint Tool Sai: Windows Ink Compatibility

Paint Tool SAI is a popular open-source digital drawing application. While it is compatible with a variety of tablets and pens, users have reported issues with pressure sensitivity and stabilisation. This is because Paint Tool SAI does not support Windows Ink, instead relying on WinTab technology. To use Paint Tool SAI with a Windows Ink tablet, users must change the settings in the application to enable pen pressure sensitivity.

Paint Tool SAI does not use Windows Ink

For example, if you are using a 2-in-1 laptop with a touchscreen and stylus, you may experience problems with pressure sensitivity and stabilization. To fix this, you will need to update to SAI2, as the older SAI1 does not support modern technology like Windows Ink. Once you have SAI2, you can go to the "Other" menu, select "Options," and choose the "Use Windows API" option. After making this change, you should be able to use your stylus with pen pressure and stabilization.

Additionally, if you are using a tablet with Windows Ink capabilities, you may need to make some adjustments to get it working with Paint Tool SAI. For example, if you are using an Xencelabs Pen and Tablet, you will need to add Paint Tool SAI to the Application line in the Xencelabs Preferences and then remove the "work with Windows Ink" check. By making this change, you can ensure that the tablet and pen work correctly with Paint Tool SAI.

It is worth noting that pen pressure sensitivity is only available in the Developer version of Paint Tool SAI (SAI Ver.2). Older versions, such as SAI Ver.1.2.5 and earlier, do not support this feature. If you are using Astropad Studio, which uses the Windows Ink API, you will need to make a similar adjustment in the program's settings. In SAI's menu bar, navigate to "Other," select "Options," and then change the "Pen Tablet Control API" to "Use Windows API." After restarting SAI, you should have pen pressure sensitivity enabled.

In summary, while Paint Tool SAI does not use Windows Ink, it is compatible with modern hardware and software by utilizing WinTab technology. By making a few adjustments to the program's settings and ensuring you are using an up-to-date version, you can take advantage of features like pressure sensitivity and stabilization on various devices, including 2-in-1 laptops and tablets.

It uses WinTab technology

Paint Tool SAI is a software application that is compatible with a variety of computers and tablets. However, it does not support Windows Ink by default. Instead, it uses WinTab technology for pen pressure sensitivity.

To use Paint Tool SAI with Windows Ink, you need to have the developer version of the software, SAI Ver.2, which includes pen pressure sensitivity. In SAI Ver.2, you can enable Windows Ink by going to the Other menu, selecting Options, and then choosing "Use Windows API" under the Pen Tablet Control API settings. After making this change, you will need to restart SAI for the changes to take effect.

It is important to note that older versions of Paint Tool SAI, such as SAI Ver.1 and SAI Ver.1.2.5, do not support Windows Ink and pen pressure sensitivity. These older versions of the software only work with WinTab technology. Therefore, if you are using an older version of Paint Tool SAI, you will need to upgrade to SAI Ver.2 to use Windows Ink.

Additionally, when using Paint Tool SAI with certain tablets, such as the Xencelabs Pen and Tablet, you may need to make adjustments in the tablet's preferences. To ensure compatibility, you should add Paint Tool SAI to the Application line in the Xencelabs Preferences and then remove the "work with Windows Ink" check. This ensures that the tablet utilizes WinTab technology, which is compatible with Paint Tool SAI.

Windows Ink is only supported in the Developer version (SAI Ver.2)

To enable pen pressure sensitivity in SAI Ver.2, you need to access the "Other" menu and select "Options". From there, you can change the "Pen Tablet Control API" to "Use Windows API". After making this change, be sure to restart SAI for the updates to take effect.

It is important to note that Paint Tool SAI Ver.2 requires a new license, so you will not be able to use an older license from Ver.1.

Additionally, if you are experiencing issues with pressure sensitivity or stabilizer problems while using a touchscreen laptop with a stylus, it is recommended to switch to SAI Ver.2 as the older version does not support modern technology like Windows Ink.

For users who prefer the Ver.1 stabilizer, there is an option to access those settings in Ver.2. This can be done by going to "Help" > "Options" > "Preferences" and checking the box for "Adjust the feeling of brush stroke of stabilizer 1-15 similar to Ver.1".

By following these steps, users can take advantage of the Windows Ink functionality in Paint Tool SAI while also having the option to maintain the Ver.1 stabilizer settings if desired.

To enable pen pressure, change the Pen Tablet Control API to Use Windows API

If you're a digital artist using PaintTool SAI and want to enable pen pressure for a more natural and intuitive drawing experience, you may need to adjust your settings to utilize the Windows Ink feature. To do this, you'll need to ensure your pen tablet's control API is set to use the Windows API. Here's a step-by-step guide on how to enable pen pressure by changing the Pen Tablet Control API to use the Windows API:

Firstly, understand that PaintTool SAI is a popular digital painting program that has been around for a while and is known for its simplicity and ease of use. While it may not have as many features as some other software, it is highly customizable and can be tailored to suit your specific needs. Enabling pen pressure allows you to vary line thickness and opacity based on the pressure you apply with your pen, adding a new level of expression to your digital artwork.

To enable pen pressure in PaintTool SAI, you need to access the program's settings and make sure your pen tablet is set up correctly. Start by opening PaintTool SAI and locating the "Options" menu. From here, select "Pen Pressure." This will open a new window where you can adjust the pen pressure settings. Ensure that the "Use Pen Pressure" checkbox is ticked; this enables pen pressure control within the software.

Now, to ensure your pen tablet works harmoniously with PaintTool SAI and Windows, you need to check and possibly change the Pen Tablet Control API settings. The API (Application Programming Interface) acts as a bridge between your tablet and the software, and using the Windows API can improve compatibility and enable Windows Ink features. To do this, go to your pen tablet's control panel or driver software. This could be, for example, the Wacom Tablet Properties if you're using a Wacom tablet.

Locate the settings related to the Pen Tablet Control API. You should see an option to switch between using the manufacturer's API and the Windows API. Change the setting to "Use Windows API" or "Windows Ink." This ensures that your tablet communicates with PaintTool SAI via the Windows API, which can provide better pen pressure sensitivity and take advantage of Windows Ink features.

By following these steps, you should now have enabled pen pressure in PaintTool SAI, and your pen tablet will respond to variations in pressure, allowing you to create brushstrokes with natural thickness and opacity transitions. Remember that you may need to refer to your specific tablet manufacturer's instructions for detailed guidance on changing API settings, as the process could vary slightly between different tablet models and brands.

In summary, enabling pen pressure in PaintTool SAI enhances your digital art experience by mimicking traditional art tools. By changing the Pen Tablet Control API to use the Windows API (or Windows Ink), you ensure better compatibility and pressure sensitivity. This allows you to focus on creating art without worrying about technical hurdles. Always keep your tablet drivers and software up to date, as manufacturers frequently release updates to improve performance and compatibility with Windows Ink.

To fix pressure sensitivity issues, switch to SAI2 from SAI1

If you're experiencing pressure sensitivity issues with Paint Tool SAI, it's likely because you're using SAI1, which was released in 2008 and does not support modern technology like Windows Ink. To fix this, switch to SAI2, which is compatible with newer hardware. Here's how:

Firstly, ensure you have the latest version of SAI2 up and running. Please note that you will need to purchase a new license as your previous SAI license will not work with SAI2. Once you have SAI2 installed, go to "Other" -> "Options". Here, you will see three radio buttons: "Use WinTab API", "Use WinTab API with Ver.1 Compatible Method", and "Use Windows API". Select the "Use Windows API" option. Click "OK" and then close SAI2 completely before reopening it and trying out a new canvas. You should now be able to use pen pressure and stabilization without any issues.

If you continue to experience problems with pressure sensitivity, there are several other fixes you can try. Firstly, ensure that your tablet driver is up to date. Outdated drivers can cause various issues when trying to draw. You can usually find and download the latest driver version on your tablet manufacturer's website. Additionally, check your brush settings in SAI. The "Min Size" bar should not be at 100% if you're looking for pen pressure. You can also adjust the "Click Detection Pressure" settings by going to "Other" (O) > "Options" (O) in the menu bar. Set the "Click Detection Pressure" bar to 0 to receive absolute pen pressure. If it's already at 0, set it to 100, click OK, and then set it back to 0.

Another solution is to change the TabletMouseSimulation value. Locate the misc.ini file in your Paint Tool SAI file directory, usually found in the SYSTEMAX Software Development folder. Open the file and find the TabletMouseSimulation entry. If the numerical value is 0, change it to 1 and then reopen SAI to see if the issue has been resolved.

If you're using a Wacom tablet, you may need to adjust your Wacom tablet preferences. Go to Control Panel > View Devices and Printers, right-click on your tablet and select "Wacom Preference File Utility". Under "All User Preferences", click "Remove". This will remove all your Wacom tablet settings, but your pen sensitivity should now be working. You can then go back and manually adjust your settings in the "Wacom Tablet Properties" window. To avoid losing your settings in the future, use the "Backup..." option in the "Wacom Tablet Preference File Utility" window to create a backup file that you can restore if needed.

Finally, if none of the above solutions work, try reinstalling Paint Tool SAI, as this can sometimes resolve stability and pressure sensitivity issues.
