    Functions for altering and converting the color of pixelbufs

Traits

Functions

  • blur
    Performs a Gaussian blur on the supplied image. sigma is a measure of how much to blur by.
  • brighten
    Brighten the supplied image. value is the amount to brighten each pixel by. Negative values decrease the brightness and positive values increase it.
  • contrast
    Adjust the contrast of the supplied image. contrast is the amount to adjust the contrast by. Negative values decrease the contrast and positive values increase the contrast.
  • crop
    Return a mutable view into an image The coordinates set the position of the top left corner of the crop.
  • crop_imm
    Return an immutable view into an image The coordinates set the position of the top left corner of the crop.
  • dither
    Reduces the colors of the image using the supplied color_map while applying Floyd-Steinberg dithering to improve the visual conception
  • filter3x3
    Perform a 3x3 box filter on the supplied image. kernel is an array of the filter weights of length 9.
  • flip_horizontal
    Flip an image horizontally
  • flip_horizontal_in
    Flip an image horizontally and put the result into the destination ImageBuffer.
  • flip_horizontal_in_place
    Flip an image horizontally in place.
  • flip_vertical
    Flip an image vertically
  • flip_vertical_in
    Flip an image vertically and put the result into the destination ImageBuffer.
  • flip_vertical_in_place
    Flip an image vertically in place.
  • grayscale
    Convert the supplied image to grayscale
  • horizontal_gradient
    Fill the image with a linear horizontal gradient
  • huerotate
    Hue rotate the supplied image. value is the degrees to rotate each pixel by. 0 and 360 do nothing, the rest rotates by the given degree value. just like the css webkit filter hue-rotate(180)
  • index_colors
    Reduces the colors using the supplied color_map and returns an image of the indices
  • invert
    Invert each pixel within the supplied image. This function operates in place.
  • overlay
    Overlay an image at a given coordinate (x, y)
  • overlay_bounds
    Calculate the region that can be copied from top to bottom.
  • replace
    Replace the contents of an image at a given coordinate (x, y)
  • resize
    Resize the supplied image to the specified dimensions. nwidth and nheight are the new dimensions. filter is the sampling filter to use.
  • rotate90
    Rotate an image 90 degrees clockwise.
  • rotate90_in
    Rotate an image 90 degrees clockwise and put the result into the destination ImageBuffer.
  • rotate180
    Rotate an image 180 degrees clockwise.
  • rotate180_in
    Rotate an image 180 degrees clockwise and put the result into the destination ImageBuffer.
  • rotate180_in_place
    Rotate an image 180 degrees clockwise in place.
  • rotate270
    Rotate an image 270 degrees clockwise.
  • rotate270_in
    Rotate an image 270 degrees clockwise and put the result into the destination ImageBuffer.
  • thumbnail
    Resize the supplied image to the specific dimensions.
  • tile
    Tile an image by repeating it multiple times
  • unsharpen
    Performs an unsharpen mask on the supplied image. sigma is the amount to blur the image by. threshold is the threshold for the difference between
  • vertical_gradient
    Fill the image with a linear vertical gradient
