Stamps

A stamp and art saving mod for for WEBFISHING using GDWeave

Keybinds (REBINDABLE IN SETTINGS :O)

Keybinds are fully customizable using the game's built in controls settings, courtesy BlueberryWolfiAPIs

• F4 Key

  • Opens my stamp menu executable or brings it to the front.

• PLUS Key (+)

  • Spawns a stamp at the cursor position.
  • Replaces the old stamp in the same position if SHIFT is held.
  • Spawns a stamp in the nearest best viewing spot CTRL is held.
  • Spawns a stamp on Canvas 1, Canvas 2, Canvas 3, or Canvas 4 if combined with 1, 2, 3, or 4, respectively.

• MINUS Key (-)

  • Toggles multiframe playback if a GIF/Video has been placed down.
  • When SHIFT is held, toggles playback speed instead.
  • When CTRL is held, resets GIF/Video to play from frame one.

• CTRL + Z Keys

  • Works as Ctrl+Z, undoing the last placed stamps in order.
  • Off map canvases will be the first things deleted
  • If this keybind is changed, CTRL will not need to be held.
  • If this isn't working, try the BACKSPACE key.

Stamp Positioning Instructions

Lock/Unlock Movement

• P Key:
  Toggle the stamp's movement lock.
  • Unlocked: You can move and adjust the stamp.
  • Locked: Movement and vertical adjustments are disabled (you can still rotate with arrow keys).

Movement (Stamp Translation)

• I: Move the stamp forward (relative to the camera).
• K: Move the stamp backward.
• J: Shift the stamp to the left.
• L: Shift the stamp to the right.

Vertical Adjustment

• U: Lower the stamp.
• O: Raise the stamp.

Rotation

• Left/Right Arrow Keys: Rotate the stamp around its vertical (yaw) axis.
• Up/Down Arrow Keys: Tilt the stamp (adjust its pitch).

Speed Adjustment

• Shift Key:
  Hold Shift to move it faster.

General Information

• You can paste images into the menu directly or select a file
• Supports art saving and image generation if using chalks by the wonderful hostileonion
• now supports looong videos (yay)
• Stamps are automatically adjusted to be upright relative to the player camera
• you might get temporarily kicked for spawning canvases in cove servers (they are considered an illegal actor)
• In-game canvases have a 200x200 resolution. I recommend keeping stamps below this size
• Off-canvas: a maximum of two chalk canvases (200*200) can be placed
• Saved stamps are located at /home/user/.local/share/webfishing_stamps_mod on Linux or %localappdata%/webfishing_stamps_mod on Windows
• Be mindful of performance and lag, especially if playing GIFs. This is a server side mod, and people sometimes dont have calico
• Gifs are no longer supported on in game canvases
• Please dont use Thunderstore Mod Manager, I suggest Gale or r2modman

Image Processing Guide

Here’s a quick overview of how to process your images:

• Color Match
  A simple, reliable option that maps each pixel to the closest chalk color. If you're unsure where to start, pick this for clean, predictable results.

• K-Means Mapping
  Groups similar colors into clusters. Great for noise reduction and simplifying complex images. Adjust the number of clusters to control how stylized the result looks.

• Dithering
  If your image has colors that don’t neatly match the available chalk palette, dithering can help fill those gaps. It creates patterns or “noise” to transition between colors smoothly. There are many dithering methods (Atkinson, Floyd, Jarvis, etc.)—each one handles color transitions differently. Generally:

  • Hybrid Dither automatically switches between methods for mixed textures.
  • Pattern Dither creates a retro, pixel-art style.

Ultimately, you should experiment with different methods to find the style that best fits your image!

Color Options

Choose what chalk colors to use by enabling or disabling them.

• Use RGB to map an image’s colors to RGB chalk.
• Use Blank to make certain colors fully transparent.
• Use Canvas Colors or Grass Colors to add the color specified to available colors for increased color accuracy.
  • This only works if you are placing on the surface specified.

What is LAB and When to Use It?

LAB is a color space that better reflects how humans perceive color, improving the accuracy of color matching compared to RGB.

• Turn LAB On: For images with subtle gradients or color shifts where precise matching matters.
• Turn LAB Off: For bold, flat colors... I think? If the blues are looking a little too red...

Basically, if you aren't happy with a result, try turning it off! It's on by default but not always better :3
