Image Manipulation Filters

resizeImage

The resizeImage function in Google Blogger is used to modify the dimensions of images, typically for displaying featured images in a specified size while maintaining the aspect ratio.

Syntax

resizeImage(imageUrl, width, height);

• resizeImage(size, ratio): Changes dimensions and aspect ratio of post images.

Parameters

• imageUrl: The URL of the image that you wish to resize.
• width: The desired width of the image in pixels.
• height: The desired height of the image in pixels (optional).

Behavior

• The function helps ensure that images fit well within your blog’s layout by resizing them to standard dimensions.
• It maintains the aspect ratio if only one of the dimensions (width or height) is provided.
• If both dimensions are specified, the image may be distorted if the aspect ratio does not match the original image.

Example

Here’s how you might use the resizeImage function within a Blogger template:

<b:if cond="data:post.featuredImage">
  <b:set
    var="resizedImage"
    value="resizeImage(data:post.featuredImage, 1200, 630)"
  />
  <img src="<b:eval expr='resizedImage' />" alt="Featured Image" />
</b:if>

In this example:

• If a post has a featured image, it’s resized to 1200 pixels wide and 630 pixels high.
• The resized image is then displayed in the template.

Considerations

• Always test the resizing to ensure images display correctly across different devices.
• Use common aspect ratios (like 16:9, 4:3) to maintain visual consistency.

By effectively using resizeImage, you can streamline the presentation of images on your Blogger pages. If you have specific use cases or require more detailed guidance, feel free to ask!
