I'm trying to replace the image using google doc api. Image is replaced but it takes the dimensions of previous and so gets cropped.
I also tried by providing height and width but it didn't work.
When I reset the image manually in google doc then the full image is showing in doc and after reset image, its height and width can be changed accordingly. But google doc API did not provide an option to reset image.
Here is a little code which replaces the image in a Google doc :
"replaceImage": {
"imageObjectId": IMAGE_ID",
"uri": REPLACED_IMAGE_URL,
"imageReplaceMethod": IMAGE_REPLACE_METHOD,
}
Is there any possible way to replace the image so that it can replace the previous image properly.
Thanks.
I don't think it is possible to avoid cropping when using the replaceImage request. As it can be seen in the official documentation, the only valid value for imageReplaceMethod is CENTER_CROP, which "Scales and centers the image to fill the bounds of the original image. The image may be cropped in order to fill the original image's bounds. The rendered size of the image will be the same as that of the original image.".
I hope this is of any help.

I'm using multer node and express to upload a image to my app. But some images shows rotate 90 degrees when it's on the client.
why is this happening?, how can I fix it?
By the way I'm using vue on the client and for the upload process, of course I use formdata
UPDATE
After research and comments from the guys above, its a EXIF problem. Any code ideas to solve this?
The behaviour you are experiencing is probably caused by the Exif Orientation metadata.
There is another question here on Stackoverflow about this problem: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images
The selected answer points to a project called Javascript-Load-Image as a possible solution, that basically means you will have to take the orientation in consideration when rendering the images to get a consistent behaviour.
Another possible alternative would be to edit/remove the orientation metadata in your backend.
Check the following resource for more information:
JPEG Image Orientation and Exif
This is most likely caused by Exif metadata (just like #Romulo suggested).
Browsers ignore Exif metadata when displaying images and that's why you're getting this behaviour.
To check that this is related to Exif take 4 pictures with different phone orientation (landscape left, landscape right, portrait, upside down). One of them will be shown properly, while the other 3 will be rotated. (Also note that if you're using the front camera, the image will also get mirrored).
Not all camera phones do this, but iOS does it consistently. The reason for this is performance. When rotation the phone the sensor also rotates and the picture taken doesn't take the rotation into consideration.
To properly show the photo, the image needs to be rotated, but if you just change the Exif metadata then you don't need to do it. Of course, any client that shows the image needs to be aware of this information (and iOS Photos and such are aware).
This has nothing to do with multer, but with the images are stored.
The bottom line is that you need to rotate the image to compensate for this.
Take a look over this npm package to adjust your image on the server side.
I'm developing an app that grabs the HTML from a webpage and looks at images, within the HTML, that can be compressed and resized.
I can do the first part no problem in node, using Sharp here:
https://www.npmjs.com/package/sharp
I can, of course, resize the same image here too. I just don't know what dimensions to use. I don't want a tiny image to scale up and so on.
Can I somehow detect the size of the image on screen using the HTML I got to begin with?
Thanks in advance.
EDIT:
Sorry for any confusion. I need to know how big the image is being displayed on the page. So, the image may be 400x400 but the css could limit it to 200x200.
If I have a large image (1000x1000) but it's only being shown on screen at 500x500, I'd know it's a great candidate for resizing.
I'm just not sure how I can resize based on it's css dimensions.
I think in Sharp there's a metadata function that lets you access image metadata, e.g. format, width, height, etc.
Example:
const image = sharp(inputJpg);
image.metadata().then(function(metadata) {
// print image width and height
console.log({
width: metadata.width,
height: metadata.height
});
});
In Sharp library,
You can get dimension from this document:
http://sharp.dimens.io/en/stable/search.html?q=dimension
Hope it will help you.
const sharpImage = sharp('test/test.jpg');
image.metadata().then(function(metadata) {
console.log(metadata);
});
I have been trying to implement a feed App like Instagram or Facebook. ImageViews have match_parent width (screen width) and wrap_content height.
The code I have used...
Glide.with(context)
.load(imageURL)
.thumbnail(0.1f)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(imageView)
;
That results into loading thumbnail first. The thumbnail is very small in size. I was expected that the thumbnail will display a faded image with the original image height.
Without thumbnail, the ImageViews do not populate any image (when loading) and then suddenly the original images comes into picture. I cannot use any place holder image as the height of the place holder image may not match the actual image to be loaded, makes it a bad user experience.
I have also tried...
Glide.with(context)
.load(imageURL)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.placeholder(null)
.into(imageView)
;
But it is not working! I was wondering how the Instagram App does those fade in loading with images (with original image height)?
I have looked into various websites including the Glide Github issues and stack overflow, but unable to find any solution! I have already wasted about 6 hours of my day. What is the way out of this problem?
Use override attribute:
Glide.with(context)
.load(imageURL)
.override(18,18)
.thumbnail(0.1f)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.into(imageView);
Also as Instagram is owned by Facebook it might be the case that they use Fresco library (not sure though).
Is there some plugin/way to crop images when they are uploaded in a Modx TV?
I got a slider with a ratio of 1:4. Now when the user uploads a image in another ratio, the image will stretch out.
I want something like Facebook does when you upload a cover image which is to high.
(PS: I want to use it later in Migx)
Like 'okyanet' mentioned you can use phpThumbOf to set the dimensions/ratio when MODx delivers the image.
Another way would be to use the extra 'Image+'. You still need phpThumbOf for this, but the Editor can define the clipping manually in the Manager. And you can define the ratio of the clipping in the TV-Setting for the image.
Use phpThumbOf. The 'zoom-crop' parameter will allow you to preserve the source aspect ratio and then crop it to the dimensions you require.
The image is processed when the page is parsed by MODX, rather than at the time of upload.
There are plenty of articles about how to use this extra, including this one:
http://www.belafontecode.com/image-manipulation-with-phpthumbof-in-modx-revolution/
I need to be able to get a path to images that cached.
While I am wondering if there is a way to do this using SDWebImage, I could probably get away with just having the knowledge to return a path to an image stored in the cache so I can display it within a uiwebview inside an image tag.
According to this https://github.com/rs/SDWebImage/issues/25 it would seem you can simply refer to the image by it's original url and it will be correctly picked up from cache.
