Ond i mi, mae 'eglurdeb' yn golygu 'definition', sydd, o ran delwedd ddigidol boed ar set deledu neu lun camera, yn gyfystyr â 'resolution'.
Rwy'n credu bod gan 'cydrannu/cydraniad' ystyr wahanol sy'n berthnasol yn benodol i brosesau cemegol - gweler diffiniad 5 yn y ddolen isod:
http://dictionary.reference.com/browse/resolution
'the act or process of resolving or separating into constituent or elementary parts'
A'r hyn dan sylw yn yr achos 'ma yw ystyr 12:
' the degree of sharpness of a computer-generated image as measured by the number of dots per linear inch in a hard-copy printout or the number of pixels across and down on a display screen'
Felly 'eglurdeb/eglurder' sy'n briodol yn fy marn i ar gyfer delweddau digidol. Rwy'n credu y gallai 'cydraniad/cydrannu' fod yn gamarweiniol.

Hwn wedi codi ei ben eto.
"high resolution digital images"
Roeddwn i wedi meddwl defnyddio "eglur iawn" - gan ddilyn GyrA:
"TV: picture resolution: eglurdeb llun"
er mwyn bod yn eglur!
Ond cefais esboniad (ar Twitter!) "Fe all eglurdeb 'llun' fod yn dda/drwg am nifer o
resymau, dim ond un agwedd yw resolution."
Diffiniad: (computer science) the number of pixels per square inch on a computer-
generated display; the greater the resolution, the better the picture
Felly, swn i'n meddwl bod "cydraniad" (yn GyrA ar gyfer Cemeg a Mathemateg) yn iawn
yma.
Byddai modd defnyddio "eglurdeb" mewn cyd-destun llai technegol.
