I am working on a page where there is a configuration setup and a preview pane. I wish for filepond to provide the bitmap(blob?) image when an image is uploaded so that it can be displayed in the live preview creator pane div tag rather than the element(filepond) it is originally shown on, is this possible.
I am using vue-filepond
You receive the file item in the onprocessfile callback. The file property contains the file object. You can use URL.createObjectURL and pass the returned URL to an image src to show the image.
Assuming you have an <img> on the page something like this should work.
const image = document.querySelector('img');
image.src = URL.createObjectURL(fileItem.file);

I built a website in plain html/css with my own design. Now I need to put this website in TYPO3 CMS 9.5.4. Unfortunately it's my first time working with TYPO3 and I don't really know what I'm doing.
What I got so far:
Most of the website is already working fine. I included fluid_styled_content and my setup basically looks like this:
page = PAGE
page.1 = FLUIDTEMPLATE
page.1 {
file = fileadmin/sitedesign/Resources/Private/Templates/Page.html
variables {
content < styles.content.get
}
}
The Page.html file is basically my whole html template and I put
{content->f:format.raw()}
where I want my content.
All content I create in the backend is displayed as I want except of images.
My question:
I can display images by creating a "Text & Images" content element and adding the images in the "Images" tab. In the "Media Adjustments" section I can now set the width and height of each element and below I can choose the number of columns.
However these do not change anything in the source code of my website i.e. in the content variable, so all images are displayed in full size.
What can I do to make the width/height appear in the source code (ideally as width/height attribute of that element)?
Hey Erik and welcome to TYPO3. Usually TYPO3 will take care of the correct images sizes when using the default Content Elements (e.g. Text & Images). But TYPO3 requires ImageMagick or GraphicsMagick installed on the server to modify the pictures.
You can check out if your system matches all requirements using the "Environment" module in the TYPO3 backend (modules on the left side of the backend). Then you will see a function called "Image processing" which will test the required image functions of your server.
I have the following codes to test the image_style_url() on the latest drupal(v7.59)
<img src=“<?= file_create_url($fileuri); ?>” />
<img src=“<?= image_style_url(“medium”, $fileuri); ?>” />
The file_create_url() can show the original image properly, and the image_style_url() can only give the styled image url, but not creating any styled image in the styled image folder.
the public:// and the /tmp directriea are in 777 permission setting, so it won’t be related to permission problem.
Can someone tell me what is wrong with my drupal?
Seems you have to create the image derivate first. Normally this happens automatically when uploading an image via an image field upload. But the automatic derivate creating might simply get skipped on file field uploads, or when using some other image which isn't managed by Drupal at all, or when you added an image style after you already uploaded the image.
Have a look at image_style_create_derivative($style, $source, $destination). Check out the comments as well as $style needs to be an array returned by image_style_load('MYSTYLE').
Creates a new image derivative based on an image style.
Only issue left open is how to check first if the derivate already exists before calling that function. Maybe you can check what file_exists(image_style_path($style_name, $file_uri)) returns, first.

Nothing wrong with your Drupal. Derivative image is not physically created until someone visits the listing where that style is used.
Example: You create new node and upload an image on it. Original image is within files folder. But if you use for example teaser image style and if you go to teaser folder the image is not created there until someone visits the page where "teaser" image style is used. You can easily test this on clean Drupal. Basically the image is created on the fly on HTTP request.
In angular2 using aberezkin/ng2-image-upload
I have in my template
<image-upload
[max]="1"
[url]="uploadUrl"
[preview]="true"
[buttonCaption]="'Select Images!'"
[dropBoxMessage]="'Drop your images here!'"
(onFileUploadFinish)="imageUploaded($event)"
(onRemove)="imageRemoved($event)"
(isPending)="disableSendButton($event)"
></image-upload>
This is part of a larger form for an e-commerce site's product capture/edit screen including this image upload
It's all great for a new product and a new image but if I have to edit an existing product and thus have the data from the server for that product, including the image, how can I pre-populate image-upload with this image thus allowing a user to keep it or delete it/change it?
Also is there a way to filter file type allowed?
So you want to let user select the image and able to change it befor Uploading
I made a simple example of preview and uploading image I think it will be helpful for you
Preview and uploade image angular2
I want to fetch image from the server, save it locally and and display when user opens the show page - with Rubymotion.
I am using AFMotion to fetch the image url as follows.
In my show screen I can get the image url with news.image_url. My doubt is how do i pass this to the layout file where I can add some styles to it like
I have found a solution to my own question. This is what i have done.
In the on_load method of the show news page, I pass the image url and set the remote_image for the UIImageView to the image url passed.
I got the solution from the red potion documentation. http://docs.redpotion.org/en/latest/cookbook/networking/
I want to put a image into a post, but it seems I just cannot get it work.
For example, this one:
http://stockcharts.com/c-sc/sc?s=ACHN&p=D&b=5&g=0&i=t88400486500&r=9913
The output is a PNG file. So in HTML tab, i put,
< img src="http://stockcharts.com/c-sc/sc?s=ACHN&p=D&b=5&g=0&i=t88400486500&r=9913">,(I leave a empty space between the < and image otherwise, stackoverflow won't allow me to put a image tag here) it just won't show up the correct image. The image you will see is "go to stockcharts.com to view this chart", that is because the URL is wrong. If the URL is correct, the image will display fine. Any way to work around?
I was trying to play around with the formatting.php file, but so far, no luck.
(It is quite strange though, if you put the URL into your IE URL bar, and press enter, it shows up fine with a chart.)
Thanks.
Your URL is a web page, NOT an image. When you try to insert the link as an image, the html IMG tag is used to specify the FILE NAME to be inserted. The file can be on a different url but it should not refer to just another uri.
to get around it, you have 4 options:
Specify the image file name directly and not the uri with the img tag.
Use iframe and put the uri
use frame (I'd not go for this)
Use Ajax and fill it in a DIV tag - most effective in my opinion.
