1. Kupu Whakataki

Kaihanga Waitohu he taputapu e whakahaerehia ana i roto i te pūtirotiro e āhei ai koe ki te waihanga i tētahi waitohu matihiko ā-ringa mā te whakamahi i tō kiore, papapa, mata pā rānei. Ka taea e koe te tuhi tika i tō waitohu ki runga i tētahi kānaweti, te whakarite i tōna tae me tōna mātotoru, te whakatika i te papamuri (tae atu ki te pūataata), ā, ka taea hoki te kaweake ki ngā hōputu whakaahua maha pērā i te SVG, PNG, JPG, me te WEBP.

He tino pai tēnei taputapu mō te haina i ngā tuhinga matihiko, te tāpiri waitohu ki ngā kōnae PDF, te whakauru waitohu ki ngā hiku īmēra, te whakarite rānei i ngā whakaahua waitohu pūataata mō ngā kaupapa hoahoa. Nā te mea ka whakahaerehia ngā mea katoa i roto i tō pūtirotiro, kāore he hiahia ki te tukuake kōnae, ki te tukatuka rānei i te taha tūmau. Ka waihangatia tō waitohu inamata, ā, ka taea te tikiake tonu i te hōputu e hiahiatia ana.

Ahakoa e hiahia ana koe ki tētahi PNG pūataata mā mō ngā kirimana, tētahi SVG ka taea te whakarahi mō te tā, tētahi JPG rānei mō te tiritiri tere, ka whakarato tēnei kaihanga waitohu i tētahi otinga tere, ngāwari hoki mō te whakamahi whaiaro me te whakamahi ngaio.

2. Me Pēhea Te Mahi

Ka whakamahi te taputapu i tētahi kānaweti HTML5 pāhekoheko e taea ai e ngā kaiwhakamahi te tuhi ā-ringa. Ka hopukina ia rārangi hei raupapa ira, tae atu ki ngā raraunga tūranga, wā, me te pēhanga (ina wātea). Ka tukatukahia ēnei ira kia noho hei ānau maheni, kia puta ai he āhua tuhi ā-ringa māori, kaua ko ngā rārangi taratara, kōpaka rānei.

Ngā Tawhā Tāuru

Rohe Kānaweti: Te mata tuhi e waihanga ai koe i tō waitohu.
Tae Pene: Kōwhiria tētahi tae tuhi ritenga i te hōputu hexadecimal (ka hurihia ā-roto ki te RGB).
Tae Papamuri: Kōwhiria he tae tōtika, he papamuri pūataata rānei mā ngā uara RGBA.
Whānui Pene: E toru ngā taumata mātotoru ka taea te kōwhiri hei whakatika i te whānui iti me te whānui nui o te rārangi.
Ōwehenga Āhua: Kōwhiria i waenga i te 16:9, 4:3, 3:4, rānei 1:1 hei whakahaere i ngā āhuatanga o te kānaweti.

Arorau Whakaatu Rārangi

I a koe e tuhi ana, ka hopukina e te pūnaha ngā takahanga tohu, pā rānei, ā, ka huri hei wāhanga ānau. Ka tātaihia te tere o te rārangi kia taea ai te whakatika hihiri i te mātotoru o te rārangi, kia puta ai te āhua pene māori. Ka penapenahia ia rārangi hei raraunga kua whakaritea, e āhei ai ngā āhuatanga pērā i te whakakore me te tuhi anō i te papamuri me te kore e ngaro te waitohu.

Ngā Ture Whakamana

Ko ngā uara whānui pene kei raro iho i te 1 ka tautuhia ki te mātotoru iti rawa e tautokohia ana.
Me whai ngā tāuru tae i te hōputu hexadecimal tika.
Ka aukatihia te whakarerekē i te rahi o te kānaweti i muri i te tīmatanga o te tuhi kia kore ai e kōpiko te waitohu.
Ka tango noa te Whakahoki i te rārangi whakamutunga mēnā kei te wātea ngā raraunga rārangi.

Ngā Hōputu Putanga

Ka taea e koe te kaweake i tō waitohu hei:

SVG – He hōputu whakairoiro ā-veketā ka taea te whakarahi, he pai mō te tā taumira-teitei.
PNG – Ka tautoko i te pūataata.
JPG – He hōputu kōpeke mō te whakamahi whānui.
WEBP – He hōputu whakaahua hou kua arotauhia.

Ngā Herenga

Kāore te taputapu e manatoko tuakiri, e whakarato whakamotuhēhēnga here ā-ture rānei.
Ka tuhia ā-ringa ngā waitohu, kāore e waihangatia aunoatia mai i te kuputuhi.
Mēnā ka whakarerekēhia te rahi i muri i te tuhi, tērā pea me muku te kānaweti.

3. Me Pēhea Te Whakamahi I Tēnei Taputapu

Kōwhiria tō ōwehenga āhua e hiahiatia ana mō te kānaweti.
Kōwhiria tētahi taumata mātotoru pene.
Tautuhia te tae waitohu e hiahia ana koe.
Mēnā e hiahia ana, kōwhiria tētahi tae papamuri (kia waiho rānei kia pūataata).
Tuhia tō waitohu mā tō kiore, mā tō mata pā rānei.
Whakamahia te Whakahoki hei tango i te rārangi whakamutunga mēnā e hiahiatia ana.
Pāwhiritia te Muku hei tautuhi anō i te kānaweti.
Tikiakehia tō waitohu hei SVG, PNG, JPG, rānei WEBP.

4. Ngā Tauira Whaitake

Tauira 1: PNG Pūataata mō Ngā Kirimana PDF

Tāuru:

Ōwehenga āhua: 4:3
Tae pene: Pango (#000000)
Papamuri: Pūataata
Whānui pene: Waenga

Putanga: download.png (papamuri pūataata)

Whakamahia tēnei kōnae hei whakauru i tō waitohu ki tētahi kirimana PDF me te kore e puta he pouaka mā ki muri.

Tauira 2: SVG Taumira-Teitei mō te Tā

Tāuru:

Ōwehenga āhua: 16:9
Tae pene: Kahurangi (#1a73e8)
Papamuri: Mā
Whānui pene: Matotoru

Nā te mea he hōputu ā-veketā te SVG, ka noho koi tonu te waitohu ahakoa ka whakarahi mō ngā pane reta, mō ngā rauemi tā rānei.

5. Ngā Take Whakamahi Mā Ngā Kaiwhakawhanake

- Ngā Pūnaha Aunoatanga Tuhinga

Whakauruhia ngā whakaahua waitohu kua tikiakehia ki ngā rerengamahi waihanga tuhinga aunoa (hei tauira, kirimana, nama, whakaaetanga hoki).

- Hopu Waitohu i te Taha Kiritaki

Whakamahia ngā raraunga whakaahua Base64 kua kaweake mō ngā tukuake AJAX:

const dataUrl = signaturePad.toDataURL('image/png');
// Tukuna te dataUrl ki te API o te tūmau mō te penapena

- Whakauru SVG ki Ngā Taupānga Tukutuku

Nā te mea he ā-veketā te putanga SVG, ka taea te whakauru tika ki te HTML:

<img src="signature.svg" alt="Waitohu Matihiko">

- Whakahaere Raraunga Haumaru

Nā te mea ka waihangatia te waitohu katoa i roto i te pūtirotiro, kāore he tukatuka taha tūmau e hiahiatia ana mēnā kāore i whakatinanahia motuhake. Ka whakaiti tēnei i te tūraru o te pānga raraunga. Ka taea e ngā kaiwhakawhanake te manatoko i ngā aho Base64 i te taha tūmau i mua i te penapena kia kore ai e penapenahia ngā tāuru hē.

- Tukatuka Papamuri i roto i te PHP

$base64 = $_POST['signature'];
$image = str_replace('data:image/png;base64,', '', $base64);
$image = base64_decode($image);
file_put_contents('signature.png', $image);

6. Pātai Auau

He mana ā-ture tō tēnei waitohu?
