html - CSS equivalent for Text Tint -


i'm trying export files adobe indesign basic html + css.

a user can select text , change text colour. using indesign sdk can fetch rgb values colour , in css file declare color: rgb(r,g,b) works fine.

you can change text tint value. upto taking tint value, converting range 0-1 , in css putting entry color: rgba(r,g,b,tint)

during testing realized tint = 0 should mean white text, didn't show on html because (in rgba) = 0 means transparent!!!

anyone knows how handle tint values in css?

there no tint, hue,saturation or brightness in css. should "build" these properties rgb color. apply tint on rgb, use expression:

when r,g,b 0..255, tint 0..1

new r = tint*r + (1-tint)*255; new g = tint*g + (1-tint)*255; new b = tint*b + (1-tint)*255;

tint convex combination of color , white color. see wikipedia.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
