Kongsi pemalam pengeditan imej Vue yang berkuasa (datang dan cuba!)

Artikel ini akan berkongsi dengan anda pemalam pengeditan imej Vue yang berkuasa yang tidak mempunyai rakan Ia boleh memutar, mengezum, memangkas, menconteng, menambah teks, dsb. pada imej.

[Cadangan berkaitan: "tutorial vue.js"]

Baru-baru ini, pengguna telah mengemukakan keperluan baharu dan guru boleh membetulkannya Tugasan gambar pelajar memerlukan pemutaran, penskalaan, pemangkasan, grafiti, anotasi, menambah teks, dll. pada gambar. Sekali imbas, bunyi macam banyak rambut akan gugur. Adakah terdapat pemalam berkuasa yang boleh mencapai fungsi di atas, supaya saya boleh mempunyai lebih banyak masa untuk menghalang tiket wanita daripada membeli semasa Double Eleven? Jawapannya sudah tentu ya.

Paparan kesan

Doodle

Pangkas

Anotasi

Putar

Bukankah ia sangat berkuasa ! Terdapat banyak lagi fungsi yang saya tidak akan tunjukkan satu persatu. Jadi tunggu apa lagi? Mari gunakannya bersama saya~

Pasang

Anda boleh melihat bahawa alat penyunting gambar hidup muncul, bukankah ia sangat mudah:

Pengoptimuman butang

Dengan menyesuaikan gaya, kami melihat butang Muat dan Muat Turun di sudut kanan atas Ia telah disembunyikan Seterusnya, kami akan menyembunyikan butang lain yang tidak digunakan (mengikut keperluan perniagaan) dan menambah butang untuk menyimpan gambar.

  // 保存图片，并上传
  save() {
    const base64String = this.instance.toDataURL(); // base64 文件
    const data = window.atob(base64String.split(",")[1]);
    const ia = new Uint8Array(data.length);
    for (let i = 0; i < data.length; i++) {
      ia[i] = data.charCodeAt(i);
    }

Kesannya adalah seperti berikut:

Anda boleh melihat bahawa butang set semula di bahagian atas, dan butang cermin dan topeng di bahagian bawah sudah tiada. Terdapat butang simpan tambahan kami sendiri di sudut kanan atas Klik butang untuk mendapatkan fail base64 dan fail gumpalan.

Ringkasan

Di atas ialah penggunaan asas tui.image-editor Berbanding dengan pemalam lain, kelebihan tui.image -editor adalah fungsinya Berkuasa, ringkas dan mudah digunakan.

Pemalam mudah digunakan, tetapi saya juga menemui pepijat kecil Apabila anda membesarkan gambar, seret kedudukan paparan dengan tapak tangan anda, dan kemudian klik butang set semula, gambar mungkin hilang. Terdapat dua penyelesaian. Satu ialah menukar kod sumber dan memanggil kaedah resetZoom untuk memulihkan nisbah zum sebelum menetapkan semula sendiri, dan selepas mengkliknya, panggil kaedah this.init untuk membuat semula .

Memberi mawar kepada orang lain akan meninggalkan wangian yang berlarutan di tangan anda. Jika anda rasa ia berguna, cuma berikan acungan jempol dan acungkan jempolnya~
