StencilConverter

StencilConverter Pro is a Windows application that transforms digital images into physical stencils or cutting vectors. The software processes bitmaps and generates sharp contours, separating printable areas from empty spaces to create reusable templates for crafts, airbrushing, sign making, or CNC routing.

• Single-color stencil conversion. Reduces any photograph or drawing to a two-tone silhouette (print/cut), ideal for techniques like stenciling or laser cutting. The algorithm prioritizes stroke continuity to avoid floating islands in the design.
• Edge detection sensitivity. Parameters to control edge detection in the original image. A low value captures minute details (suitable for portraits), while a high value simplifies the silhouette (recommended for logos and text).
• Line thickness control. Allows specification of minimum bridge width in the stencil. This function ensures the physical stability of the template, especially important when working with fragile materials like paper or thin vinyl.
• Contour smoothing (anti-aliasing). Applies mathematical filters to remove pixel stair-stepping, generating cleaner, more professional vector curves without requiring post-processing in other software.
• Export to vector formats (SVG, PDF, DXF). Saves the result as a lossless, scalable file. The DXF format is compatible with CAD software and CNC machinery.
• Export to raster formats (PNG, JPEG, BMP). Generates high-definition raster images ready for printing on paper or acetate. Output resolution can be configured up to 1200 DPI.
• Mask inversion (positive/negative). Instantly converts the stencil design: swaps cutting areas with printing areas. This option is critical for techniques like sandblasting or screen printing.
• Real-time preview. Displays a simulation of the stencil result while modifying parameters. Includes a zoom mode to inspect complex edges and details before final export.
• Batch processing. Applies the same conversion settings to dozens or hundreds of images simultaneously. Automates repetitive workflows, such as preparing materials for serial production.
• Monochrome print mode. Optimizes output for inkjet or laser printers, ensuring black areas are completely opaque and white spaces are free of ink residue.
• Cropping and framing. Integrated tools to select the exact area of the original image for conversion. Eliminates the need for external image editing before processing.
• Project history. Logs recent configurations and processed files to resume previous work or replicate results consistently without reconfiguring all parameters.

Development of StencilConverter Pro began in 2018 by a team of software engineers based in Europe, specializing in computer graphics and digital fabrication. The application is written in C++ using the Qt framework for its graphical interface, ensuring high performance in image processing and vector geometry generation.
