imgapp's Issues

I merged 2 images. How I get the URL of the resulting image in Drive?

Thanks for this library.

I was able to resize 2 images and then merge them into one.
However, I need to get the URL of the resulting image to save it on a CMS.
How do I get it?

Feature Request: Resolution of image (ppi)

Is it possible to find the image resolution measured in pixels per inch (PPI)
Similar to: https://github.com/MikeKovarik/exifr#installation

Many thanks

Can you add an option to set the height of the image instead of width?

This is particularly useful for vertical images. If this would be possible I would be very grateful.

Images on Team Drives

Seems to not work for images on a team drive.

If I move the image to my drive and run your resize, it works fine. But errors out on the file ID on a team drive.

Add option to send in blob instead of FileId?

I want to use your ImgApp in a script but I dont have the files in google drive yet. I will however be grabbing from Twitter profile images and wanting to resize them from 48x48 to 32x32. I can grab the blob from the URL they give me to the profile image, so it would be nice not to have to save a copy to Google Drive in the meantime as I process it and then commit the blob to a github repository within the same script.

I looked at the code and it appears the top of the coffee script is what ddrives the user accessible functionality. If we added the following I believe we can achieve this:

/**
 * <h3>usage</h3>
 * var res = ImgApp.doResizeOnBlob(blob, width);<br>
 *<br>
 * @param {string} blob The blob of the image to resize
 * @param {integer} width Resized width you want
 * @return {Object} JSON object {blob: [blob], originalwidth: ###, originalheight: ###, resizedwidth: ###, resizedheight: ###}
 */
function doResizeOnBlob(blob, width) {
  return new ImgApp().DoResizeOnBlob(blob, width)
}

Then add a DoResizeOnBlob method that will contain a call to GetResizedSize and a similar set of returns as DoResize would return.

I am not that familiar with Coffee scripts, so I figured I would put in a request instead of trying to develop something myself without much understanding of how it all works or how to properly test.

This functionality would be really really helpful and seems like an easy thing to implement. Alternatively, you could have the end of DoResize return what the internal function for this new functionality would return, so the code isnt being duplicated, just broken out so it had more options for users. But again, not entirely sure how it all works, so I shall let you figure out if you wish to attempt that path as well.

Issue with images over a certain filesize?

I started using ImgApp successfully, but then tried changing my sample image.
Initially I was using a 1200x1200 pixel simple png image that was only 16KB in size.
When I changed it to a file that was larger in terms of file size, I started to get an error:

Exception: Request failed for https://lh3.googleusercontent.com returned code 400. Truncated server response: <!DOCTYPE html>
<html lang=en>
  <meta charset=utf-8>
  <meta name=viewport content="initial-scale=1, minimum-scale=1, width=device-width">
  <titl... (use muteHttpExceptions option to examine full response)

I haven't found a way around that yet. It seems like the limit is something between 70 and 75 KB.

doRisize() stopped working.

I am working on a tool that works with HtmlSerivce in GAS to shrink images.

The doRisize(), which used to work, does not run and gives the following error.

stack:Error: '*****************' is not compatible file. Error message is {}
    at ImgApp.DoResize (code:308:15)
    at Object.doResize (code:35:23)

On the other hand, in the test environment (different script ID) with the exact same source,
doResize() runs and shrinks the image.

Note that getSize() is still available in the same environment.

Do you have any idea what the cause might be?

Unable to look up library

Hi, I'm getting this error when trying to run the script
"Unable to look up library. Check the ID and access permissions and try again."

I used the following ID to add the library: 1T03nYHRho6XMWYcaumClcWr6ble65mAT8OLJqRFJ5lukPVogAN2NDl-y

"Is not compatible file"

Hello.
I have some TIFF files over 200 mb.
I wanted to get data about the width and height of an images. But Google does not process files over 200 MB. The get.Width() and get.Height() request returns 0. For TIFF files less than 200 MB, I can get their sizes.

Fragment of code:

let fileId = file.getId();
let dims = Drive.Files.get(fileId, {supportsAllDrives: true}).imageMediaMetadata;
let width = dims.width;
let height = dims.height;`

I tried using your doResize () function but got this answer: "Is not compatible file"

Is it possible to solve this problem using your application? Or maybe there are some other ideas?

Log Error

Would it be possible to make it log the error that it's catching on https://github.com/tanaikech/ImgApp/blob/master/src/ImgApp.coffee#L113-L114

get screenshot page 1

can you help me to make function to get screenshot every page 1 in a document in a folder?

ただし、他の新規GASスクリプトファイルを作成し、oauthScopesがない状態でもエラーがでます。

Feature Request: Resize and convert

According to this: https://developers.google.com/apps-script/reference/drive/file#getAs(String)

It appears we can get the blob as a different type. I am wondering if we can make doResize optionally always return the image as a passed in mime-type?

I think it can be used when we first get the blob to convert it or alternatively, to make use of this functionality right before returning the new blob when performing the resize.
