A simple moiré tester/visualizer related to halftone printing using the HTML5 Canvas API
There's no real indication of which screen controls affect which screen without changing a value for one of the screen attributes (i.e. dot size, spread, angle, row or column count). It'd be beneficial to be able to identify which set of controls go with which screen that's displayed.
After closing 'Create independent screen angles' issue, implement feature to allow user to select common screen printed angles.
Examples:
Y 0°, C 15°, M 75°, K 45°
Y 0°, C 15°, M 45°, K 75°
Y 90°, C 105°, M 75°, K 15°
Y 90°, C 165°, M 45°, K 105°
Allow the user to select which screen should should be printed next. Currently screens print in yellow, cyan, magenta, black order only.
The angle slider limits the user to only change the angles between the screens by a fixed angle (ex. The user chooses 15° so the yellow screen is drawn at 0°, cyan at 15°, magenta at 30° and black at 45°). The user may want to adjust angles independently to cover other common halftone printing angles.
Angles should be allowed to be drawn based on the origin of the screen - or with relation to the last drawn screen angle.
(i.e. if a yellow screen is drawn with a zero angle (0°), and the following screen, say cyan, is drawn with an angle of 15°, the following screen, say magenta, when given an angle of 30°, should be drawn at 30° (from the zero angle) when relative to origin OR at 45° (30° more than the previous screen angle) when relative to the previous screen.
There should be an option for creating screen angles relative to other screen angles.
