![]() Once saved, you can then use the filter option in the resize and modify Twig filters to specify the filter to use.Ī common example would be a basic thumbnail - you want this to always be format: jpg, mode: cover, quality: 60, max_width: 200, max_height: 200 and maybe background: #fff. By clicking the Filters tab at the top, you can specify a filter "code" which can apply a set of enhancements and modifications to an image. Both codes are accepted (one just maps to the other)įilters in the Image Resize plugin, while following a similar concept to filters in Intervention Image, are handled differently in this plugin.įilters are specified in the Settings > Image Resizer page. String containing 3 numbers (0-255), comma separated. ![]() Both codes are accepted (one just maps to the other)Ĭolorize the image. Set a background color - Hex color (with or without hashtag). Rotate the image (width / height does not constrain the rotated image, the image is resized prior to modifications) Both codes are accepted (one just maps to the other) Increases/decreases the contrast of the image Usage of the modifiers is simple, either add them in a key: value fashion in the 3rd argument of the resize filter, or by using the modify filter, as such: Stretch and morph it to fit exatly in the defined dimensionsĪ few image adjustment tools and filters have been implemented into this plugin, which utilise their Intervention Image library counterparts. Resize the background image to cover the entire container, even if it has to stretch the image or cut a little bit off one of the edges Resize the background image to make sure the image is fully visible ![]() Resizing modes are almost synonymous to CSS3 background-size modes to make it easier to remember. Resize to height 700px and automatically calculate width:Ī third argument is available, options, which allows you specify the resizing mode, along with any other image modifications which are detailed below. Resize to width 1000px and automatically calculate height: Resizing requires at least one of the two dimension arguments. Twig Filter: | resize(int $width, int $height, array $options)īasic resizing in Twig is done using the | resize filter. ![]() We’ll set some basic visual styles for the card itself, a quick update to the expected h3 headline, then essential styles to begin to style the card image.Please review the full documentation and code on GitHub if you require further assistance. Next, we’ll create a minimal set of baseline styles for the. But we’re going to explore two modern CSS properties that don’t involve extra math, give us more flexibility, and also allow keeping the semantics provided by using a real img instead of an empty div.įirst, let’s define the HTML semantics, including use of an unordered list as the cards’ container: ![]() You may have also used this idea to maintain a 16:9 ratio for video embeds, in which case the padding value is found with the formula: 9/16 = 0.5625 * 100% = 56.26%. Setting a padding value as a percent results in a final computed value that is relative to the element’s width. One advantage this has is using an older trick for aspect ratio which uses a zero-height element and sets a padding-bottom value. I’ve implemented this solution many times myself in the past. A consequence is uneven positions of the card content which really stands out when you present a row of cards.Īnother previous solution besides cropping may have been to swap from an inline img to a blank div that only existed to present the image via background-image. And while this can be resolved by cropping ahead of time, we can still encounter issues due to responsively sized containers. The common problem with this setup is that we may not always have perfect control over what the image is, and more importantly to our layout, what its dimensions are. To prepare for our future image effects, we’re going to set up a card component that has a large image at the top followed by a headline and description. The newly supported aspect-ratio property in combination with object-fit provides a remedy to this headache of the past! Let’s learn to use these properties, in addition to creating a responsive gradient image effect for extra flair. A classic problem in CSS is maintaining the aspect ratio of images across related components, such as cards. ![]()
