New TableCellViewer: Rewrite

[dietzc]

Issue for the new gallery based implementation of the TableCellViewer. See https://github.com/knime-ip/knip/tree/combinedImgViewer

Open Points:

• Double check all nodes which use the view component if they still work as expected:
• [x] Check Kernel Creator
• [x] Check Structuring Element Creator
• [X] Check Interactive Annotator
• [X] Check Interactive Segment Viewer
• [X] Check Labeling Editor
• [X] Check Parameter Adjuster
• [ ] Escape Key should close view and go back to table
• [ ] Add hot-keys to dimensions (Select active channels with shift+something and browse them with mouse-wheel or +/-) and table navigation (some smart control)
• [ ] Up, down, left, right arrows should be linked to up, down, left, right arrows on keyboard.
• [ ] Default size of view should match with image
• [ ] Current column name should be clearly visible
• [x] Overlay View: Info about two images should be visible (maybe two or n info panels?)
• [x] Check for other integrations (ClearVolume) if they still work in the new viewer. At the moment, some of them (ClearVolume) don't. make sure they work.
• [ ] BoundingBoxRenderer with names enabled should render names next to each other.
• [ ] Double-check if bounding-boxes retrieved from renderer are correct (seems to be a bit buggy for cells which touch the border).
• [x] Faster preview (if possible) of images while hovering over keys
• [x] Equivalent to row view should be available for column based view on the left
• [x] Jump to first entry in next row (or ask if ...) if the end of a row has been reached and user wants to see next image
• [X] Allow overlay of Labelings and Images
• [x] Rename to Image Viewer
• [x] Nicer info panel over the image.
• [x] Some users want to automatically enable Normalization etc. We should allow them to set default settings in a preference page in KNIME.
• [x] Maybe normalize by default? I'm also happy for design-suggestions. Somehow I still have the feeling that we waste a lot of space.
• [X] Boxes on the right, so be auto-aligned to the top such that they are not jumping around
• [X] Unsupported cells should be either ignored or the user should have the possibility to skip the unsupported cells. at the moment, the user is stuck.
• [X] Table Cell Viewer should still be available as a single node
• [X] Renderer Selection should be a drop-down box.
• [X] allow overlay renderings as well as displaying multiple images at the same time (synchronized and non-synchronized scrolling through dimensions
• [X] Add table navigation control
• [X] Add tabs for currently displayed images + merged (=global) settings on the right
• [X] After opening the viewer Normalize is active but the Saturation slider is inactive.
• [X] Allow to manually set background color of viewer (currently it's black per default).

thanks @AndreasBurger, it already looks amazing.

the currently selected column (or cell) should be highlighted better than with the old viewer. especially tables containing mostly black pictures are problematic.

[dietzc]

@AndreasBurger can you take care of this?

[AndreasBurger]

I've modified the TableCellRenderer to highlight the currently selected cell (see attached image). Using this approach, however, enables this behaviour in all dialogs - which I think is actually nice.

@dietzc Any reservations?

@dietzc Any reservations?

Somehow this indicates that the hiliting mechansim of KNIME is enabled, which is not the case. Maybe we can use another mechansim/color to hilite the selected cell (red overlay or so?).

[maierl]

The hiliting vs selection could be confusing, but using a border in general seems fine to me. A colored overlay on a color image will cause problems.

[maierl]

i'd prefer to open the full image only after double-clicks, so i could select images without opening them right away.

[dietzc]

needs cleanup.
