Default example results to 0 height of component

[vedmant]

Hi, I just used default example, here is my component:

<template>
  <Modal :value="value" content-class="max-w-3xl" @input="$emit('input', false)">
    <div class="p-6 pb-16 m-auto max-w-xs">
      <div class="mb-6 text-xl font-semibold leading-7 text-center text-white">
        {{ $t('Create a new team') }}
      </div>
      <div class="mb-6 aspect-w-1 aspect-h-1">
        <div v-if="file">
          <cropper
            class="cropper"
            :src="file"
            :stencil-props="{
              aspectRatio: 1
            }"
            @change="change"
          />
        </div>
        <div v-else class="flex flex-col justify-center items-center bg-gray-800">
          <Btn color="red" class="mb-6" @click="$refs.file.click()">
            <IconUpload class="mr-2 w-5 h-5 text-black" />
            {{ $t('Upload team avatar') }}
          </Btn>
          <div class="text-sm font-medium leading-5 text-center text-gray-400" style="max-width: 8.5rem;">
            Minimum 600 x 600 JPG, JPEG or PNG
          </div>
          <input ref="file" type="file" style="display: none" accept="image/png, image/jpeg" @change="file = $event.target.files[0]">
        </div>
      </div>
      <InputGroup v-model="form.name" :label="$t('Team Name')" class="mb-10" />
      <Btn color="red" class="justify-center w-full" size="xl" :loading="loading">
        {{ $t('Create Team') }}
      </Btn>
    </div>
  </Modal>
</template>

<script>
import { Cropper } from 'vue-advanced-cropper'
import Modal from '../UI/Modal'
import Btn from '../UI/Btn'
import IconUpload from '../UI/Icons/IconUpload'
import InputGroup from '../UI/InputGroup'
import 'vue-advanced-cropper/dist/style.css'

export default {
  components: { InputGroup, IconUpload, Btn, Modal, Cropper },

  props: {
    value: Boolean,
  },

  data: () => ({
    file: null,
    loading: false,
    form: {
      name: '',
    },
    zoom: 0,
  }),

  methods: {
    change (e) {
      console.log(e)
    },
  },
}
</script>

When I select image cropper has 0 height:

[Norserium]

@vedmant, the src attribute receives an url to an image, dataURL or blob, not an image file itself.

Take a look at the sandbox example.

[vedmant]

@Norserium I tried blob, but still can't make it work, height is 0. Can it be that initially there is no image selected and I don't show cropper <div v-if="image.src">.

Here is still not working code based on the example:

<template>
  <Modal :value="value" content-class="max-w-3xl" @input="$emit('input', false)">
    <div class="p-6 pb-16 m-auto max-w-xs">
      <div class="mb-6 text-xl font-semibold leading-7 text-center text-white">
        {{ $t('Create a new team') }}
      </div>
      <div class="mb-6 bg-gray-800 aspect-w-1 aspect-h-1">
        <div v-if="image.src">
          <cropper
            ref="cropper"
            class="h-full cropper"
            :src="image.src"
            :stencil-props="{
              aspectRatio: 1
            }"
            @change="change"
          />
        </div>
        <div v-else class="flex flex-col justify-center items-center">
          <Btn color="red" class="mb-6" @click="$refs.file.click()">
            <IconUpload class="mr-2 w-5 h-5 text-black" />
            {{ $t('Upload team avatar') }}
          </Btn>
          <div class="text-sm font-medium leading-5 text-center text-gray-400" style="max-width: 8.5rem;">
            Minimum 600 x 600 JPG, JPEG or PNG
          </div>
          <input ref="file" type="file" style="display: none" accept="image/*" @change="uploadImage">
        </div>
      </div>
      <InputGroup v-model="form.name" :label="$t('Team Name')" class="mb-10" />
      <Btn color="red" class="justify-center w-full" size="xl" :loading="loading">
        {{ $t('Create Team') }}
      </Btn>
    </div>
  </Modal>
</template>

<script>
// import Cropper from 'cropperjs'
import { Cropper } from 'vue-advanced-cropper'
import Modal from '../UI/Modal'
import Btn from '../UI/Btn'
import IconUpload from '../UI/Icons/IconUpload'
import InputGroup from '../UI/InputGroup'

import 'vue-advanced-cropper/dist/style.css'

export default {
  components: { InputGroup, IconUpload, Btn, Modal, Cropper },

  props: {
    value: Boolean,
  },

  data: () => ({
    image: {
      src: null,
      type: null,
    },
    loading: false,
    form: {
      name: '',
    },
    zoom: 0,
  }),

  methods: {
    uploadImage (event) {
      /// Reference to the DOM input element
      const { files } = event.target
      // Ensure that you have a file before attempting to read it
      if (files && files[0]) {
        // 1. Revoke the object URL, to allow the garbage collector to destroy the uploaded before file
        if (this.image.src) {
          URL.revokeObjectURL(this.image.src)
        }
        // 2. Create the blob link to the file to optimize performance:
        const blob = URL.createObjectURL(files[0])

        // 3. Update the image. The type will be derived from the extension and it can lead to an incorrect result:
        this.image = {
          src: blob,
          type: files[0].type,
        }
      }
    },

    change ({ coordinates, canvas }) {
      console.log(coordinates, canvas)
    },

    destroyed () {
      // Revoke the object URL, to allow the garbage collector to destroy the uploaded before file
      if (this.image.src) {
        URL.revokeObjectURL(this.image.src)
      }
    },
  },
}
</script>

Here I have 0 heights in cropper dom:

But image blob is loaded:

Weird that there is no errors.

[Norserium]

Can it be that initially there is no image selected and I don't show cropper

It shouldn't be a problem, but you can try to remove it and test the image loading. Also, try to set the fixed height for the cropper itself.

By the way, what's the version of the cropper do you use?

[vedmant]

@Norserium I use "vue-advanced-cropper": "^1.7.0", something weird is happening here, even when I set src to a url:

<Cropper
            ref="cropper"
            class="w-full h-full cropper"
            :stencil-props="{
              aspectRatio: 1
            }"
            src="https://images.pexels.com/photos/4218687/pexels-photo-4218687.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=650&w=940"
            @change="change"
          />

I see src is null on Cropper component in dev tools:

[Norserium]

@vedmant, could you sent me the full html code of the fragment?

[vedmant]

@Norserium Do you mean this:

<div class="w-full h-full cropper vue-advanced-cropper"><div class="vue-advanced-cropper__stretcher" style="height: auto; width: auto;"></div> <div class="vue-advanced-cropper__boundaries" style="width: auto;

[Norserium]

@vedmant yes. Is this code a generated result of this template? It's pretty hard to say, what the problem do you have. You should try to clear your code as much as possible, because I'm sure that the problem somewhere in your code.

To start disable, for example, all your styles; try to move cropper outside the modal window and etc.

[Norserium]

@vedmant, any news?

[vedmant]

@Norserium Hey, sorry, I think it's something related to my project setup, the same components works ok in the fiddle, but I can't find the issue for now, it's hard to debug Vue js internals to see why src prop is not passed. I'll try use other cropper. Thanks for your help, I really appreciate this.

[Norserium]

@vedmant, I have some spare time to look via Team Viewer what's the reason of this issue. So if you ready, write me an email (it's in the profile) with the access details and the convenient time (UTC).

[vedmant]

@Norserium Thanks, I'll send you message!

[Norserium]

@vedmant, notify me here, when you've sent the message.

[vedmant]

@Norserium Hey, I sent an email to you.

[Norserium]

It is somehow related to #51.

I will reopen that issue and close this. @dminchev workaround works, but it's need to investigate why.

[Norserium]

@vedmant there are the details of investigation, just in case.
