SixLabors.Samples.ImageSharp

Runnable ImageSharp samples that load real image files from assets/imagesharp and write generated files to output/imagesharp.

Run the project from the repository root:

dotnet run --project SixLabors.Samples.ImageSharp\SixLabors.Samples.ImageSharp.csproj -c Release

Samples

ResponsiveImageSample

Shows a typical web image pipeline:

  • loads one landscape JPEG
  • applies AutoOrient() before resize operations
  • crops a 16:9 hero image with ResizeMode.Crop
  • removes EXIF metadata from the exported hero image
  • writes the same processed pixels as JPEG and WebP
  • writes a square PNG thumbnail

Outputs:

  • responsive-hero.jpg
  • responsive-hero.webp
  • responsive-thumbnail.png

MetadataAndFormatConversionSample

Shows how to inspect an encoded image before decoding all pixels:

  • uses Image.Identify(...) to read size information
  • uses Image.DetectFormat(...) to identify the source format
  • reads pixel depth, alpha representation, bounds, frame count, and resolution from ImageInfo
  • loads, orients, resizes, annotates the image with a metadata HUD, and converts the JPEG source to PNG

Outputs:

  • metadata-converted.png

ThumbnailContactSheetSample

Shows image composition with a fixed layout:

  • loads landscape and portrait inputs
  • normalizes orientation
  • crops each source to a uniform tile size
  • draws every tile into one larger image

Output:

  • contact-sheet.jpg

PixelRowsSample

Shows direct pixel generation with ProcessPixelRows(...):

  • creates a blank Image<Rgba32>
  • maps each pixel to the Mandelbrot complex plane
  • writes each generated color directly into the row span

This is intentionally not a grayscale, histogram, or color-conversion sample; ImageSharp already provides higher-level processors for those workflows.

Output:

  • mandelbrot-fractal.png

AvatarAndMaskingSample

Shows ImageSharp.Drawing clipping with a real image:

  • crops a portrait into a square avatar
  • builds a rounded clip shape with RoundedRectanglePolygon
  • uses DrawingCanvas.Save(..., clipPath) to clip subsequent drawing
  • draws the avatar into a transparent image so the clipped corners remain transparent

Output:

  • avatar-rounded.png

PolygonClippingSample

Shows boolean path clipping with ImageSharp.Drawing:

  • builds a subject path and a clipping path
  • groups symmetric operations (Intersection, Union, and Xor) separately from Difference
  • labels each operation with both its name and operator form, such as Union: A | B
  • shows both Difference: A - B and Difference: B - A because Difference depends on operand order
  • draws the clipped result with a photo fill
  • overlays the original paths so the operation can be compared visually

Output:

  • polygon-clipping.png

TextMeasurementVisualizerSample

Shows how text measurement maps to drawn glyphs:

  • measures the same text in separate panels
  • prepares the text once with TextBlock
  • measures and renders that prepared block instead of shaping text twice
  • fills the logical advance, glyph bounds, and renderable bounds regions
  • labels renderable bounds as the union of advance and bounds
  • keeps each measurement separate so the regions can be compared without overlapping outlines

Output:

  • text-measurement-visualizer.png
