I'm planning on reworking xdraws and drawregion to draw the background and text as separate functions. To do this I need to understand some things:
As I understand it, the behavior is to have all attribute effects on color (e.g. bold brightening, italic/underline colors) affect only the foreground and not the background when in normal mode, and affect only the background and not the foreground in reverse (ATTR_REVERSE) mode. Is this understanding correct? As I understand it, the behavior for MODE_REVERSE is to use RGB color inversion, and not bg/fg swapping (so yellow-on-red becomes blue-on-cyan, not red-on-yellow) , on all colors _except_ for the default bg/fg colors. Is this understanding correct? Is the above outlined behavior actually correct by the standards / desirable / does it match the behavior of other terminals? config.def.h says " Another logic would only make the simple feature too complex." but I find that in making this change supporting the current behavior (my understanding as outlined above) is actually more complex (because it requires me to duplicate attribute color mapping in both functions) There is also, as far as I can tell, no support for brightening the background for ATTR_BLINK. -- Random832
