Bugfix Update
November 14, 2023Today's update fixes LNP support in Flash, Inkscape, and TVPaint.
Here's the list of other fixes included in this update. Huge thanks to Garrett and Stephanie for helping me test fixes!
- Tweaked pulled string physics so that string doesn't bounce while pulling cursor.
- Fixed rare end-of-line trail bug.
- Workaround for Huion tablet driver bug that randomly inserts [0, 0] positions in tablet data.
- Tablet data could sometimes be ignored at the start of a line.
- Pen button generated right-clicks were sometimes being blocked.
- Overlay renderer wasn't falling back correctly to GDI on startup if problem with Direct2D.
- Overlay graphics would be offset when using Direct2D renderer on Win7/8 with a dpi above 96.
- When attaching to windows, incorrect window could be found under the cursor on Win7/8 with a dpi above 96.
Theme Menu
October 27, 2023Based on user feedback from last week's update, I decided to make the UI themes easier to use. You can now select one directly from the Settings/Theme menu!
If you want to make your own theme, add a subfolder under %LOCALAPPDATA%\Lazy Nezumi Pro\themes\. If this folder contains mainStyle.qss or toolbarStyle.qss, it will be added to the menu list at startup.
The currently selected theme qss files are actively monitored for changes, and reloaded automatically. The same now also applies to the toolbar.xml file.
A minor fix was also applied to the stylesheets so that the link icon used by perspective rulers gets shown correctly when active. (Thanks Chutkat!)
DPI/Themes Update
October 19, 2023Today's update adds proper high-DPI support to LNP's windows. This means no more blurry window scaling! New window and toolbar menu settings have been added that will let you set a fixed window scale. The default option is "Auto Window Scale", which will scale each window according to the DPI of the monitor it's in.
LNP's UI stylesheets have been updated for a more consistent look across different scales. The preset toolbar's stylesheet is now also customizable! I took this opportunity to create some new themes based on LNP's original "ClassicOrange" style. If you want to use one of these, or create your own, click here for more info. Higher resolution toolbar images have also been added. (Thanks Aaron!)
The UI now uses better default fonts that will make text more readable (especially for Japanese, Korean, and Chinese), and you can also change the font type and base size for each language by editing the lazynezumipro.ini file.
Misc Changes and Bugfixes
Here's the rest of the changes and bugfixes in this update:
- The preset drop-down list should now be wide enough to not cut off long preset names.
- Added status bar message when custom stylesheet gets reloaded.
- Toolbar icons can now be loaded from user data folder if path starts with ~.
- Added drag & drop support to the license activation window.
- Increased pulled string max amount to 400.
- Increased perspective view radius max amount to 20k.
- Misc optimizations in main app (mainly at startup).
- Added new menu for window setting to turn off show/hide animations.
- Bugfix: app would crash when using shortcut to turn off ruler while hovering over a ruler handle.
Bugfix Update
August 28, 2023Today's patch update fixes two more regressions that were introduced in the Core Refresh update.
Line ending catch-up would sometimes lag in some apps, and pen tilt/twist data wasn't passing through when not being processed by LNP.
Also, lines will now be processed even while pressing a pen button, for users who do this accidentally while drawing.
Bugfix Update
July 25, 2023Today's patch update fixes a couple of bugs and regressions introduced in the Core Refresh update.
LNP was causing random lockups when drawing with the mouse or certain tablets. Thanks to Chutkat for reporting this.
Line endings were sometimes cut short, or wouldn't have the proper angular momentum. Thanks to Montie and Lorant for reporting this.
Bugfix Update
July 13, 2023Today's patch update fixes a couple of issues reported by users.
The first issue was causing a delay at the start of lines for some Huion tablets using Windows Ink. This was causing the start of the lines to be flat. Thanks to Chutkat and Diego for reporting this.
The second issue was causing the overlay position to not always track well with the current cursor position. Thanks to Yoshida for helping me figure this one out!
Hooked Window Margins
July 10, 2023Today's update adds a way to tell LNP to ignore your mouse and pen input for certain zones of your attached windows. This is useful for applications like Krita and Clip Studio that don't provide a separate window handle for their canvas area. By setting the window margins via the Attach To Window menu, you won't have to turn LNP off when interacting with elements outside the canvas area, such as color wheels, menus, and toolbars.
Overlay Changes
Here are the changes and bugfixes for LNP's overlay:
- In overlay max refresh mode, the renderer will now skip frames if it can't keep up with incoming messages (fixes lag on some systems).
- Overlay circles won't be rendered if they are outside the viewport (fixes lag on some GPUs).
- Added new overlay settings for opacity while drawing and line width scale.
- Bugfix: removed overlay update lag after pen-up.
- Bugfix: megacrosshair wasn't updating when LNP was off.
- Bugfix: overlay position wasn't updating over non-client areas.
Misc Changes and Bugfixes
And here's the rest of the changes and bugfixes in this update:
- Added preset shortcut option to toggle On/Off if preset is already selected.
- Bugfix: updated "speed smooth" preset so that it behaves like before Core Refresh update.
- Bugfix: stay on top setting wouldn't reload correctly in some cases.
- Bugfix: fixed typo in tilt lock script.
- Bugfix: workaround for Gaomon tablet driver bug that could cause random lockups in Photoshop.
- Bugfix: perspective ellipse could become broken when zooming out too much.
Bugfix Update
June 26, 2023Today's patch update fixes a couple of bugs, and some regressions introduced in the Core Refresh update. Special thanks to Michelle, Feff, and Kita for the bug reports!
- Windows Ink messages could interfere with Wintab processing after coming back from another window, causing a glitchy first line.
- User interface clicks in Clip Studio would be blocked when using Tablet PC mode (Windows Ink).
- Lifting the pen away from tablet before catch-up could finish the line would cause glitchy end-of-line trails (Clip and other apps using Windows Ink).
Windows Ink Pen lag fix Bugfix
June 22, 2023As the new "Windows Ink pen lag fix" setting is still very experimental and has been causing problems for some people, this option is now off by default until you turn it back on again. My apologies for all the trouble and the multiple bugfix updates!
If you do try it, please let me know if you run into any problems so that I can try to address them. If you tried it yesterday and were having menu, drag&drop, or random double-click issues, be sure to try it again with today's update, as those issues should now be fixed.
Special thanks to Mike, Rune, Wei, Jeoren, Graziano, and everyone else who submitted speedy bug reports!

Core Refresh
June 20, 2023This month marks ten years since I started working on Lazy Nezumi Pro. Wow!
First off, thank you to everyone who has supported my work all these years! When I started this project, I had no idea what to expect, but I didn't really believe I would be able to survive as an indie dev for very long. Your support and ideas for new features have kept me going.
So today's update is a bit special. One of the most requested features for LNP has been a way to lock its rulers in place. For a long time, I thought this wasn't possible because of limitations with how Photoshop was reading its input data. I had done some experiments, but they were never successful.
I've learned a lot over the years, and a lot of the early assumptions that were used to build LNP have changed. Last month, I had a revelation while doing some new experiments, and realized that this could actually be possible!
I hesitated, because it would mean re-writing a lot of old code, and changing the low level architecture of LNP's processing functionality. Some code I hadn't even looked at in years. This would also mean the possible introduction of new bugs, and old bugs creeping back in. But ultimately I decided it would be worth it for all the new possibilities it would unlock.
This was one of the hardest updates to make, but I'm pretty happy and excited with the result: rulers and scripts in LNP will now be able to start lines wherever they want! While this update itself doesn't add ruler locking options yet, I will be adding these in future updates. I already have a ton of ideas, but please email me your suggestions (and bug reports)!
So what does this update actually change for you right now? Read on!
New Smoothing Mode
I've added a new position smoothing mode called "Inertia". This is a physics based smoothing algorithm based off the old "weighted" script. It's a dynamic-only mode (catch-up always on), and is intended for drawing fast, flowy lines. I really like how this one feels, and it can provide as much smoothing as Moving Average with less lag.
Now that this algorithm has its own mode, you can use whatever pressure smoothing and script options you want with it. I've added a new script called "pressure speed scale" that works really well with this one. The new "Smoothing - Inertia" preset is already configured to use it. It's great for calligraphy!
Windows Ink Pen Lag Fix
If you've used recent versions of Photoshop, you may have noticed this really annoying lag when using your pen in certain windows.
Microsoft created this problem years ago, refused to fix it, and never even bothered explaining to developers how to avoid it. Users have been disabling Windows Ink for years because of this, but they end up without pressure because PS won't use Wintab (the other tablet API) unless a special settings file is installed. Some tablets don't even have Wintab drivers, or they might be really buggy, so this isn't an option for them.
This update adds an experimental fix for this! Simply check the new "Fix Windows Ink pen lag" option via [Settings/Edit Photoshop Options] in LNP, and you should be all set. This option is off by default. If you do try it, please let me know if you run into any problems so that I can try to address them.
Overlay Changes
As part of the Core Refresh done for this update, I've rewritten the code that handles input for LNP's overlay window, and fixed many interaction bugs in the process.
A new setting called "Ruler handle size on hover" will make it easier to grab ruler handles and double-click them to reset their parameters. There also shouldn't be any more interaction lag when clicking them with a pen in Windows Ink enabled apps.
I've also added a new "Max" resfresh rate option. When this option is selected, the overlay will update its graphics every time the cursor position changes (while not drawing). On modern systems, this doesn't have a big performance cost, but it will make LNP's rulers look super smooth, so definitely give it a try!
Misc Changes and Bugfixes
While revisting and rewriting so much old code, I was also able to find and fix a bunch of bugs. Here's the list, along with the other misc changes provided in this update:
- Pen pressure and orientation data are now only processed when the pre-script processed position changes (or the pen is still at the starting position). This makes it easier to control pressure changes when using the Pulled String smoothing mode.
- Better Windows Ink integration with latest version of Sai2.
- Added a new "Pressure On/Off" global keyboard shortcut, for when you want to quickly turn off pressure sensitivity.
- Skipping duplicate pen input packets is now only done for Microsoft's buggy Wintab driver for Surface devices. This will make auto-draw scripts faster.
- Processing is cancelled when certain popup windows appear (ie. PS dialog boxes).
- Added a workaround for a Windows Ink pen driver bug that was causing glitchy and missing lines. (Thanks to CHIENXU for reporting this one!)
- Line processing should no longer start when right-clicking or double-clicking with a pen button.
- Fixed the high pressure blotch that would sometimes appear at the start of the first line drawn after auto alt-tab.
- Releasing ctrl at the same time as clicking a ruler handle would sometimes cause app to start drawing a no-pressure line.
- Lines would sometimes not be shown when drawing fast (Sai, Clip).
- Thin trails could sometimes be drawn between lines when drawing fast (Sai, Clip).
- Space-panning wouldn't offset rulers in some situations.
Spring Update
May 09, 2023Today's update improves some of the rulers, adds new scripting capabilities, and fixes some bugs. Read on for details.
New Perspective Handles
Here are the changes for the Linear Perspective ruler:
- Added a new handle on the center line that sets the View Tilt by sliding the horizon up and down. In some cases, this method feels nicer than changing it via the handle on the vertical (blue) vanishing line.
- Holding ctrl+shift when interacting with the measure handle now changes number of ticks.
- Holding ctrl+alt when interacting with the measure handle now changes the tick subdivision.
- Holding ctrl+shift when clicking the grid handle will now toggle grid-only guide visibility.
- Added handles to slide the fixed axes position along each axis (hold shift to snap to grid).
Scripting Update
Here are the updates to the scripting engine:
- Mapped the current canvas zoom to a new 'zoom' script constant. This will help you generate patterns that scale with the canvas zoom.
- Added new script input vars for pen tilt: tx, ty, sr, ste, sta, stx, sty. TiltX and TiltY (tx, ty) are another way of representing pen tilt. The other variables are the tilt values at the start of a stroke.
- Added new script functions: mixDeg, mixRad, minArcDeg, minArcRad. These will help you work with angles. Minarc returns the shortest angle path between two angles, and the new mix functions use this when interpolating (which also prevents a jump at the 0-360 discontinuity).
- The unit for the pen tilt variables has been changed to degrees.
- Updated the 'misc/auto rotate' script to use starting pen rotation angle.
- Added a new 'misc/tilt lock' script that can lock pen tilt and twist angles during a stroke.
Bug fixes
This update also improves existing features and fixes some bugs:
- Don't reinit overlay when Qt5 menus and tooltips open (prevents click-stealing bug in Krita and other apps).
- Don't hide overlay when Snipping Tool's video recorder toolbar gets focus.
- Better ellipse box mode snapping behavior.
- Bugfix: ellipse magnetic ticks could interfere with box mode in some cases.
- Bugfix: script could be run before pen input vars were set in some cases.
- Bugfix: at the end of a stroke, cursor would sometimes jump back to the start (Clip, SAI).
- Bugfix: dynamic line endings could get stuck when using fixed pressure modes (Clip, SAI).
Bugfix Update
April 08, 2023Here are the changes in today's update:
- Added missing vs2022 runtime dlls to installer. The plugin couldn't be loaded for users without these installed.
- Bugfix: ending the Windows session while LNP was minimized to the system tray would cause it to exit without saving settings.
- Bugfix: potential fix for rare crash at Photoshop exit.
Perspective Guide Visibility
February 15, 2023Today's update adds a couple of user requested features.
The first one is the ability to show/hide the Linear Perspective ruler's dynamic guides via keyboard shortcut, which you can setup via Settings/Edit Shortcuts/General Shortcuts.
The second is a change in how the keyboard shortcuts work for presets. Using a shortcut for a preset that is already selected will now toggle On/Off for that preset. This allows for some more flexible shortcut configurations, and not having to setup a shortcut specifically for On/Off.
