Crate fimg

fimg

Provides fast image operations, such as rotation, flipping, and overlaying.

Organization

Image types:

• Image: the main image type.
• DynImage: This is the image type you use when, say, loading a png. You should immediately convert this into a
• ImageCloner: This is… a Image, but about to be cloned. It just allows some simple out-of-place optimizations, that .clone().op() dont allow. (produce with Image::cloner)
• uninit::Image: A uninitialized image. Used for performance optimization.

Operations

Affine:

• Image::rot_90
• Image::rot_180
• Image::rot_270
• Image::flip_h
• Image::flip_v

Drawing:

• Image::box, Image::filled_box, Image::stroked_box
• Image::circle, Image::border_circle
• Image::line, Image::thick_line
• Image::points
• Image::quad
• Image::poly, Image::border_poly
• Image::tri
• Image::text

Scaling: Image::scale

Misc image ops:

• Image::repeated
• Image::overlay, Image::overlay_at, Image::overlay_blended
• Image::blur
• Image::crop

feature flags

• scale: enables the scale module.
• save: enables Image::save, via the png crate.
• text: enables Image::text, via the fontdue crate.
• blur: enables Image::blur, via the stackblur crate.
• real-show: Image::show, if the save feature is enabled, will, by default, simply open the appropriate image viewing program. if, for some reason, this is inadequate/you dont have a good image viewer, enable the real-show feature to make Image::show open up a window of its own. without the real-show feature, Image::show will save itself to your temp directory, which you may not want.
• default: [save, scale].

• ImageCloner
  A neat way to clone a image.
• SubImage
  A smaller part of a larger image.

Enums

• DynImage
  Dynamic image. Can be any of {Y8, YA8, RGB8, RGB16}.

Traits

  This blends the images together, like imageops::overlay.
• ClonerOverlay
  Overlay but owned
• ClonerOverlayAt
  OverlayAt but owned
• Cropper
  Trait for cropping a image.
• Overlay
  Trait for layering images ontop of each other. Think magick a b -layers flatten a
• OverlayAt
