! Introduction
|
|
|
|
The image widget displays images that can be specified as a remote URL or the title of a local tiddler containing the image.
|
|
|
|
! Content and Attributes
|
|
|
|
Any content of the `<$image>` widget is ignored.
|
|
|
|

|
|

|
|

|
|

|
|
! Responsive images and `<map>`
|
|
|
|
[[Image maps area|https://developer.mozilla.org/en-US/docs/Web/HTML/Element/area]] coordinates are numbers of CSS pixels, therefore they do not scale. If you want to use responsive images, you can use a `svg` and `foreignObject`:
|
|
|
|
<svg viewBox="0 0 330 333" xmlns="http://www.w3.org/2000/svg" width="50%">
|
|
<foreignObject width="100%" height="100%">
|
|
[img[Tiddler Fishes.svg]]
|
|
</foreignObject>
|
|
<g transform="translate(-216 -290)" >

! Image Status Classes
|
|
|
|
<<from-version "5.2.2">> The following CSS classes are automatically added to the `<img>` element to indicate the status of the image. Note that only one of these classes will be added at the same time.
|
|
|
|
|''tc-image-loading'' |When the image is being loaded |
|
|
|''tc-image-loaded'' |The image has been loaded successfully |
|
|
|''tc-image-error'' |The image could not be loaded |
|
|
|
|
! External Images and the ''_canonical_uri'' field
|
|
|
|
When used to display tiddler-based images, the image widget operates in two distinct modes:
|
|
|
|
* If the ''_canonical_uri'' field is present then it is used as the ''src'' attribute of the generated `<img>` element and the ''text'' field is ignored
|
|
* Without the ''_canonical_uri'' field, the image widget generates an `<img>` element that embeds the image data directly using a `data:` URI.

See ExternalImages for more details.
