dotCooCoo 0779da299b Image Tools: Color Mask hides chosen colors of an image while its pixels stay ...

Object › Plug-ins › Image Tools gains Color Mask… (`addon.image.colorMask`),
Remove Color Mask and Apply Color Mask. Color Mask hides colors of the
selected images without changing their pixels. It matches colors as Remove
Background does: the edge color, the corner color or picked colors, with
Contiguous, Match, Tolerance and Softness. The mask is kept with the image
object and saved with the document: its settings, and a PNG of the image's
pixels with the hidden colors made clear, at the source's depth with its
color profile and resolution. It is a VectorCraft addition.

- The canvas (clip groups and white-shape opacity masks included),
  printing and separations, PDF (soft masks of CMYK images included), SVG,
  EPS, the raster formats, the legacy .ai and .ai editing data, EMF/WMF,
  DXF and the flattener draw the masked pixels. A linked image stays
  linked, and an output that would refer to its file writes the masked
  pixels instead.
- Copy and paste, placing a document and placed documents carry the masked
  pixels with the image, under the names they are given there.
- The dialog opens on the selected image's mask settings, with a Preview.
  Without settings, the command returns them and changes nothing.
- Setting, removing and applying a mask are each one undo step, and no
  step is added when nothing changes. Apply makes the masked pixels the
  image's own and embeds a linked image. A mask that hides nothing is only
  taken off, and the image keeps its pixels and its link.
- When an image's own pixels are replaced (Update Link, Relink, Crop
  Image, a recolor, a linked file read again on open), its mask is made
  again for the new pixels, in every art tree and in opacity-mask art.
  Crop Image cuts the image's own pixels. When the new pixels can't be
  masked, the mask keeps its settings and hides nothing.
- Objects in `ids` that are not images, CMYK images, linked images that
  show their preview, images past the decode allowance, masks that would
  hide every pixel, and grayscale images colorized with a process color
  are refused. The Eyedropper, Object Mosaic, Create Gradient Mesh, Crop
  Image's trim and Image Trace read the image's own pixels.
- An image is selected by a click anywhere in its frame, as before.

Remove Background now also refuses a grayscale image colorized with a
process color. Its result has an alpha channel, and a process color is
refused on a grayscale image with transparency.
