C daim ntawv prototype
tsis muaj dabtsis cmd_gauge (int16_t x,
int16_t y,
int16_t r,
uint16_t xaiv,
uint16_t loj,
uint16_t me,
uint16_t val,
uint16_t ntau);
Cov lus qhia
x
X-ko taw ntawm gauge center, hauv pixels
y
Y-coordinate ntawm gauge chaw, hauv pixels
r
Radius ntawm cov koob ntsuas pa, hauv pixels
kev xaiv
Los ntawm vim tus hu gauge hu yog twv nrog 3D effect thiab cov nqi ntawm cov kev xaiv yog
xoom. OPT_FLAT tshem tawm cov nyhuv 3D. Nrog xaiv OPT_NOBACK, tus
tom qab tsis tuaj. Muaj kev xaiv OPT_NOTICKS, cov zuam cim tsis yog
kos. Nrog rau kev xaiv OPT_NOPOINTER, tus pointer yog tsis kos.
loj
Tus lej ntawm cov khoom loj loj ntawm tus xov tooj, 1-10
me me
Tus lej ntawm cov khoom me me ntawm tus xov tooj, 1-10
val
Gauge qhia tus nqi, ntawm 0 thiab ntau, suav nrog
ntau
Tus nqi siab tshaj plaws
Kev piav qhia
Cov ntsiab lus ntawm lub cev dimension yog
Tick marks yog muab tso rau ntawm 270 degree arc, clockwise pib ntawm txoj haujlwm ntawm sab hnub poob
Cov me zuam me yog cov kab ntawm r * (2/256), loj r * (6/256)
Ticks raug kos nyob ze ntawm r * (190/256) mus r * (200/256)
Tus pointer kos nrog cov kab ntawm dav r * (4/256), mus rau ib qho
r * (190/256) los ntawm qhov chaw
Lwm qhov xaus ntawm kab yog txhua qhov chaw 90 degrees perpendicular rau
qhov kev taw qhia pointer, ntawm qhov kev khiav r * (3/256) los ntawm qhov chaw
Xa mus rau cov tshuab hluav taws xob cav cov voj voog ntawm lub cev kom paub ntxiv.
