Classes¶
AsinhMapping (minimum, dataRange[, Q]) |
A mapping for an asinh stretch (preserving colours independent of brightness) |
AsinhZScaleMapping (image[, Q, pedestal]) |
A mapping for an asinh stretch, estimating the linear stretch by zscale |
Display ([frame, backend]) |
Create an object able to display images and overplot glyphs |
Event (k[, x, y]) |
A class to handle events such as key presses in image display windows |
LinearMapping ([minimum, maximum, image]) |
A linear map of red, blue, green intensities into uint8 values |
Mapping ([minimum, image]) |
Base class to map red, blue, green intensities into uint8 values |
Mosaic ([gutter, background, mode]) |
A class to handle mosaics of one or more identically-sized images (or Mask or MaskedImage ) |
ZScaleMapping (image[, nSamples, contrast]) |
A mapping for a linear stretch chosen by the zscale algorithm (preserving colours independent of brightness) |
