Size of downloaded image?


Size of downloaded image?

I wish did fix the issue. The size of the image is not available until it is open. Test for width and height in the ImageOpened event handler.
Code
code :
  var bitmap = new BitmapImage(new Uri(uri));

  // ImageOpened fires when image is downloaded and decoded
  bitmap.ImageOpened += (s, args) =>
  {
    var w = bitmap.PixelWidth;
  };

  // setting the source causes the ImageOpened or ImageFailed event to fire.
  // image2 must be in visual tree

  image2.Source = bitmap;

Hope that helps First of all, your decodeFile() method, which supposed to decode the image file from cache and resize it to smaller bitmap, will not resize it to a SQUARE SIZE. so, when you load your decoded bitmap into your ImageView, without any specified option in your layout or in your ImageView, you will get your image with original respect ratio.
What I suggest here is:
code :
<your.package.to.ENESquareImageView
    android:id="@+id/mini_cover"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:contentDescription="@null"
    android:scaleType="centerCrop" />

Hope that helps SOLUTION
I created a UITableViewCell class and implemented all the attributes of my labels and image view:
code :
- (void)awakeFromNib {

    imageView.frame = CGRectMake(8, 8, 54, 54);
    title.frame = CGRectMake(79, 14, 200, 21);
    subtitle.frame = CGRectMake(79, 31, 200, 33);
    date.frame = CGRectMake((self.window.frame.size.width - 140), 0, 100, 21);
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";
    HomeTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    cell.title.text = [arrayTitle objectAtIndex:indexPath.row];
    cell.subtitle.text = [arraySubtitle objectAtIndex:indexPath.row];
    cell.date.text = [arrayDate objectAtIndex:indexPath.row];
    cell.imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@", [arrayImage objectAtIndex:indexPath.row]]]]];

    return cell;
}

it should still fix some issue It looks like you're using PIL or Pillow. resize doesn't alter the image in-place, it returns a new image. So you need this:
code :
image = image.resize((basewidth,hsize), Image.ANTIALIAS)
^^^^^^^^

hope this fix your issue Looks like some kind of misconfiguration on the server side. It won't return the image unless you specify that you accept gzip compressed content. Most web browsers nowadays do this by default, so the image is working fine in browser, but for wget or curl you need to add accept-encoding header manually. This way you will get gzip compressed image. Then you can pipe it to gunzip and get a normal, uncompressed image.
You could save the image using:
code :
wget --header='Accept-Encoding: gzip' -O- http://sklepymuzyczne24.pl/_data/ranking/686/e3991/ranking.gif | gunzip - > ranking.gif
