Image Actions

In the Actions Tab, you can stack multiple operations to process your images in bulk. These actions are processed natively using Rust’s image crate, ensuring maximum performance and memory safety.

Here are the categories of actions available:

Adjustments

Section titled “Adjustments”

Fine-tune the lighting, color, and sharpness of your images.

  • Brightness / Contrast: Standard exposure adjustments.
  • Saturation / Vibrance: Boost or mute colors intelligently.
  • Hue Rotate: Shift the entire color spectrum of the image.
  • Blur / Sharpen: Soften details or enhance edges.
  • Temperature / Tint: Adjust the white balance (Warm/Cool and Green/Magenta).
  • Gamma: Adjust midtone brightness without clipping whites/blacks.
  • Color Balance: Fine-tune the RGB channels independently.
  • Replace Color: Select a specific color in the image and swap it for another.
  • Auto Contrast (Normalize): Automatically stretch the histogram to maximize dynamic range.

Filters

Section titled “Filters”

Apply stylistic effects to your images.

  • Grayscale / Sepia: Classic monochromatic and vintage filters.
  • Negative (Invert): Invert all colors to their exact opposites.
  • Vignette: Darken the edges of the image to draw focus to the center.
  • Add Noise: Add film grain or digital noise.
  • Channel Extraction: Isolate only the Red, Green, or Blue channels.
  • Threshold: Convert the image to pure black and white based on a cutoff value.

Transformations

Section titled “Transformations”

Change the physical dimensions and orientation.

  • Resize (Absolute & Proportional): Scale images up or down.
  • Crop: Cut away the edges of the image.
  • Rotate / Flip: Reorient the image (e.g., 90 degrees, horizontal flip).
  • Canvas Resize: Change the canvas size without stretching the image, adding padding.

Stylize & Misc

Section titled “Stylize & Misc”

Advanced and fun operations.

  • Swirl: Apply a distortion swirl effect to the center of the image.
  • Pixelate: Reduce the resolution to create a blocky, retro 8-bit effect.
  • Add Border: Add a solid colored frame around the image.
  • Add Text (Watermark): Overlay text on the image with customizable font sizes and colors.

Tip: The order of your actions matters! Resizing an image before adding a watermark will make the watermark look different than if you resized it after adding the watermark. Kythia Convert processes your stack exactly from top to bottom.
