class Opal::Image::PixelBuffer

• Opal::Image::PixelBuffer
• Reference
• Object

Overview

2D TrueColor pixel buffer supporting direct coordinate access, algorithmic generators, high-fidelity nearest & bilinear interpolation, and file decoders.

Defined in:

opal/image/pixel_buffer.cr

Constructors

• .from_bmp(bytes : Bytes) : PixelBuffer

  Parses 24-bit or 32-bit uncompressed Windows BMP bytes

• .from_ppm(content : String) : PixelBuffer

  Parses Netpbm PPM (P3 ASCII or P6 Binary) image stream

• .new(width : Int32, height : Int32, default_color : Color = Color.none)
• .new(width : Int32, height : Int32, pixels : Array(Color))
• .sample_gem(w : Int32 = 48, h : Int32 = 48) : PixelBuffer

  Generates a radiant 24-bit TrueColor Opal gemstone with multi-faceted refraction

• .sample_landscape(w : Int32 = 48, h : Int32 = 36) : PixelBuffer

  Generates a retro twilight mountain landscape with sunset gradient and sun

Instance Method Summary
