Text Display

Scrolling Text

`lc_scrolltext_*`

Automatically scroll text when content exceeds the container dimensions. Perfect for displaying long descriptions, testimonials, or variable-length content.

Element Setup:

Element type: <rect>
ID format: lc_scrolltext_* (e.g., lc_scrolltext_description, lc_scrolltext_testimonial)

Input Format:

"This is a long text that will automatically scroll if it exceeds the container dimensions"

Behavior:

Scrolling applies only when text exceeds container size
If text fits, displays normally without scrolling
Smooth animation for better readability

Usage Example:

{% raw %}

<!-- In your SVG -->
<rect id="lc_scrolltext_description" width="400" height="100" />

<!-- In your dataset -->
{{ description }} = "This is a lengthy customer testimonial that talks about how amazing the product is and includes many details that might exceed the available space in the container."

{% endraw %}

Common Use Cases:

Customer testimonials
Product descriptions
Terms and conditions
Project summaries
User feedback

Faded Text

`lc_fadetext_*`

Apply a fade effect at the end of text to indicate content continues beyond visible area. Provides a visual cue for overflow without animation.

Element Setup:

Element type: <rect>
ID format: lc_fadetext_* (e.g., lc_fadetext_summary, lc_fadetext_notes)

Input Format:

"This text will have a fade effect applied at the end to indicate more content"

Behavior:

Fade gradient automatically applied at text end
Provides subtle overflow indication
Static display (no animation)

Usage Example:

{% raw %}

<!-- In your SVG -->
<rect id="lc_fadetext_summary" width="400" height="80" />

<!-- In your dataset -->
{{ summary }} = "Executive summary explaining the key points of the quarterly business review and highlighting the major achievements"

{% endraw %}

Common Use Cases:

Executive summaries
Preview text
Notes and annotations
Abbreviated content
Space-constrained descriptions

Choosing Between Scroll and Fade

Use `lc_scrolltext_*`	Use `lc_fadetext_*`
User needs to read full content	Content is supplementary
Long testimonials	Preview/teaser text
Complete information required	Space is very limited
Dynamic narration	Static presentation

Images and Videos

Dynamic Images

`lc_image_*`

Display uploaded images dynamically from your data source. Perfect for logos, product images, customer photos, or any personalized visual content.

Element Setup:

Element type: <rect>
ID format: lc_image_* (e.g., lc_image_logo, lc_image_profile)

Alignment Options:

Control horizontal alignment within the rect using ID patterns:

lc_image_* → Center aligned (default)
lc_image_left_* → Left aligned
lc_image_right_* → Right aligned

Note: Images are always vertically centered within the rect, regardless of horizontal alignment.

Input Format:

CDN URL:

"https://cast.app/images/cast-dark-text-01.svg"

Dataset Variable:

{% raw %}

{{ company-logo }}

{% endraw %}

Where company-logo contains the image URL

Error Handling:

If no image is provided or file type is unsupported, displays:

"No Image"

Usage Example:

{% raw %}

<!-- In your SVG -->
<!-- Center aligned (default) -->
<rect id="lc_image_company-logo" width="200" height="200" />

<!-- Left aligned -->

{{ company-logo }} = "https://cast.app/images/cast-dark-text-01.svg"

{{ csm-photo }} = "https://cast.app/images/cast-dark-text-01.svg"

{% endraw %}

Image Behavior:

Aspect Ratio: Images maintain their aspect ratio and are never upscaled
Scaling: Large images scale down to fit within the rect; small images display at their natural size

Consistent sizing - Use same dimensions for multiple dates
Valid formats - Always use ISO format (YYYY-M-D)
