Maybe this is one of the impossible ones, but here goes.
I have a ton of images of qr-codes in a folder. It doesnt matter if its in google drive or in a local folder for me.
I would a script that automaticly loads all images in column A and then the file names in column B. AND automaticly adds new images when uploaded to the google drive folder.
Example:
Qr1.jpeg will be loaded into cell a1 and cell b1 will be "Qr1"
Qr2.jpeg will be loaded into cell a2 and so on..
It would be nice if the images are scaled to 10x10 cm. :)
Is this even possible?
Hope you guys can help!
Thanks!

Not the Complete Answer...but it's a part
I've been working on getting thumbnails into my spreadsheet ever since you asked this question. I won't go into all the paths I took but I finally found this Github link in the comments of this issue
Which resulted in the following code:
function myImageFiles()
{
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('MyImages');
var files = DriveApp.getFiles();
var s='';
var cnt=1;
while(files.hasNext())
{
var fi=files.next();
var type=fi.getMimeType();
if(type==MimeType.GIF || type==MimeType.JPEG || type==MimeType.PNG)
{
sh.appendRow([cnt++,fi.getName(),type,fi.getUrl(),'=IMAGE("' + getThumbNailLink(fi.getId()) + '",1)']);
}
}
}
function getThumbNailLink(fileId)
{
var file=Drive.Files.get(fileId);
return file.thumbnailLink;
}
The result is now I have a spreadsheet with all of my image filenames and thumbnails. You'll need Advanced Drive and take a close look at getThumbNailLink().

I want to extract the dimensions of the image from the URL in google Sheet. Found this Library that does exactly what I am after.
https://github.com/tanaikech/ImgApp#getsize
But I am very new to this scenario and wondering what exactly I should use in the script editor. If I follow the above I can't get the results.
Please help.
Thanks
When I saw your provided sample Spreadsheet, it seems that the Spreadsheet and your script are as follows.
function myFunction() {
var blob = DriveApp.getFileById(fileId).getBlob();
var res = ImgApp.getSize(blob);
var width = res.width;
var height = res.height;
}
Modification points:
In this case, you put a custom function of =myFunction(A2) to a cell. But your script doesn't retrieve the value.
At the custom function, DriveApp.getFileById(fileId) cannot be used because of the limitation.
Your script doesn't return the values.
When these points are reflected in the script for achieving your goal, it becomes as follows.
Modified script:
Please replace your current script with the following script and save the script. And, please put a custom function of =myFunction(A2) to a cell. By this, the width and height are returned.
function myFunction(url) {
const blob = UrlFetchApp.fetch(url).getBlob();
const { width, height } = ImgApp.getSize(blob);
return [[width, height]];
}
Testing:
When this modified script is used for your sample Spreadsheet, it becomes as follows.

I am trying to copy a workbook with multiple sheets into a single sheet. I have found other libraries that work fine for copying ranges or sheets into the bottom of another but they don't copy the images. Is this possible with EPPlus? If it isn't are there other libraries that do this?
I was able to get this accomplished by using GemBox.Spreadsheet. The were quite responsive to bug(s) in their library and it all functions correctly now.
var excelDrawings = sheet1.Drawings.Where(x => x.DrawingType ==
eDrawingType.Picture).ToList();
foreach (var excelDrawing in excelDrawings)
{
var name = excelDrawing.Name;
var image = excelDrawing.As.Picture.Image;
singleSheet.Drawings.AddPicture(name, image);
}
function extractTextFromPDF() {
// PDF File URL
// You can also pull PDFs from Google Drive
// this Fall2019_LLFullCatalog.pdf will not insert - internal error on insert is all the feedback that gets logged"
// doesn't matter if I retrieve it from the university website or if I first copy it to my google drive and then retrieve it from there
//var url = "https://uwf.edu/media/university-of-west-florida/offices/continuing-ed/leisure-learning/docs/Fall2019_LLFullCatalog.pdf";
//var url = "https://drive.google.com/drive/u/0/my-drive/Fall2019_LLFullCatalog.pdf";
// both of these pdfs will insert just fine. Size is not the issue because this one is much larger than the one I need to insert
var url = "https://eloquentjavascript.net/Eloquent_JavaScript_small.pdf";
//var url = "https://img.labnol.org/files/Most-Useful-Websites.pdf";
var blob = UrlFetchApp.fetch(url).getBlob();
var size = blob.getBytes().length;
var resource = {
title: blob.getName(),
mimeType: blob.getContentType()
};
// Enable the Advanced Drive API Service
var file = Drive.Files.insert(resource, blob, {ocr: true, ocrLanguage: "en"});
// Extract Text from PDF file
var doc = DocumentApp.openById(file.id);
var text = doc.getBody().getText();
return text;
}
See comments in code above that describe the problem.
The PDF that I need to insert with OCR is not working - regardless of whether I retrieve it from the original site or retrieve a copy that I put on google drive. However, two other PDF urls will insert just fine and one of them is considerably larger than the one that fails.
What else could be the issue, if not size limitation?
Thanks,
Steve
It could very well be a bug in the Chrome API. Not all PDF software is created equal, check if the PDF can be read in Adobe Acrobat as a simple test.
I have an image with longitude and latitude coordinates, can any one tell me how do i get it? I have tried
if (CrossMedia.Current.IsPickPhotoSupported)
{
MediaFile photoPicked = await CrossMedia.Current.PickPhotoAsync();
if (photoPicked != null)
{
//await DisplayAlert("Photo Location", photoPicked.Path, "OK");
//path = photoPicked.Path;
using (Stream streamPic = photoPicked.GetStream())
{
var picInfo = ExifReader.ReadJpeg(streamPic);
ExifOrientation orientation = picInfo.Orientation;
//MainImage123.Source = ImageSource.FromStream(() => photoPicked.GetStream());
latitude = picInfo.GpsLatitude;
longitude = picInfo.GpsLongitude;
var filepath = photoPicked.AlbumPath;
var filepath1 = photoPicked.Path;
}
}
}
It works when I picked photo and trying to get its coordinates, but I have to take multiple photos from image gallery and find its coordinates.
does any one know how to read image geo coordinates? please help me.
You can use the ExifLib.PCL Nuget Package to read an image metada, by viewing your "code sample", i think you are using the Plugin.Media to take images/get images from the galery, be sure to use SaveMetaData = true when taking an photo from your app.
Once you have set the SaveMetaData to true, use the ExifLib to obtain the MetaData like this:
MediaFile photo;
using (Stream streamPic = photo.GetStream())
{
var picInfo = ExifReader.ReadJpeg(streamPic);
double lat = picInfo.GpsLatitude;
double lon = picInfo.GpsLongitude;
}
Also, as a plus, you have even more info on the photo (date taken, author, size, etc.).
UPDATE:
After Reading it again, it seems that the problem is that you are not able to pick multiple images from the galery, and NOT being able to get the lat and lon from the photos. At the moment, Plugin.Media doesn't support multi-picking.
Your question was unclear however - I think you are trying to make it work with multiple images together. How you can be able to pick multiple images together?
The plugin "CrossMedia" doesn't support picking up multiple images.
Your solution requires a lot of work to be done to be able to Pickup multiple images at once. So Follow this nice step-by-step tutorial here:
https://xamgirl.com/select-multiple-images-from-gallery-in-xamarin-forms/
With above you will be able to get all the images you need at once.
After you get List, all you have to do is to loop through those images and call your existing code.
I've got an Array with 17 web links of images
var products:Array;
trace(products)
// Ouput :
"http://www.myWebsite.com/zootopia.jpg"
"http://www.myWebsite.com/james.jpg"
"http://www.myWebsite.com/tom.jpg"
..etc
If I do products[10].movieimage; the output will be the 9th link (something like : "http://www.myWebsite.com/lalaland.jpg")
I'm looking for downloading every images without a dialog box.
I manage to do so for 1 image with the specific link, like that :
function saveImage (event:Event):void {
var stream:URLStream = new URLStream();
var image1:File = File.documentsDirectory.resolvePath("test.jpg");
var fileStream:FileStream = new FileStream();
stream.load(new URLRequest("http://www.myWebsite.com/lalaland.jpg"));
stream.addEventListener(Event.COMPLETE, writeComplete);
function writeComplete(evt:Event):void {
var fileData:ByteArray = new ByteArray();
stream.readBytes(fileData,0,stream.bytesAvailable);
fileStream.openAsync(image1, FileMode.UPDATE);
fileStream.writeBytes(fileData,0,fileData.length);
fileStream.close();
trace("writeComplete");
trace(image1.url);
}
}
Question : Is there a way to download all the images with the web links of my products array ? (and if images already exist, replace them. I could use if (image1.exists){ if (image2.exists){ ..etc for each image. But maybe there is a simplier solution)
If you could show me how, with a bit of code, I could that.
Also, note that I'd like to load the images then in Uiloader, like that :
function loadImages():void {
uiloader1.source = image1.url;
uiloader2.source = image2.url;
etc...
}
Don't over think it. You have your array of images. You have your tested routine for saving one image. Now put it together:
Some function initializes things and kicks it off.
Either splice out (or pop out) an item on the array – OR use a index var to access an item in the array
Pass that to your download function.
When the download completes either pop another item off the array OR increment your index. But first you would test if array.length== 0 OR `index > array.length. If either is true (depending on which method you use), then you are done.
If you want to get fancy you can show a progress bar and update it each time your download completes.
