Stamper provides a way of turning any image into a token for use with tabletop games.

Stamper supports loading an image from the local filesystem or directly from a website and turning it into a token. The resolution of the final token is customizable, and layer sizes are automatically resized to fit the desired output-resolution.

• Drag-and-drop to load images. Load any image from a local file or skip the download by drag-and-dropping from your browser.
• Border and overlay selection. Stamper comes with simple borders and overlays that can be recolored and layered on top of the loaded image.
• Custom layers. Adding your own borders and overlays to Stamper is fast and easy. Layers can be SVG or bitmap image files.
• Direct upload to Imgur. Finished tokens can be saved locally or uploaded directly to Imgur for easy sharing.
• Custom token sizes. Stamper lets you customize the output size of your token, and scales the layers to fit.
• Easy image manipulation. Pan-, zoom-, and rotation-functionality is supported through simple mouse-actions.
• Add text to your token. Stamper lets you place text on top of your token in any position, size, font, rotation, and color.

Stamper layers can be added automatically through the UI with the option of autogenerating the mask, or by manually placing json files in the layers folder. The structure of the json files is as follows:

• name: The name of the layer. Required
• file: A relative path from the layers-folder to the image file. This is the image that is shown on top of the input image in Stamper. Required
• mask: A relative path from the layers-folder to the image to use as a mask. On border layers, this mask is applied to the underlying input image. On overlay layers, this mask is applied to the overlay itself. Pixels with the color #FF00FF00 (#AARRGGBB) will be removed from the underlying image, all other colors are ignored. Optional
• type: The layer type. Allowed values are border or overlay. Required

{
  "name": "Circle",
  "file": "svg\\bCircle.svg",
  "mask": "svg\\bCircle_mask.svg",
  "type": "border"
}

Stamper is Windows-only and requires v4.6.2 or newer of the .NET Framework. You can get the latest release of Stamper here.
