## Description

The Stretch Factor Calculator handles the math for scaling digital content between different resolutions. It figures out how much an image or video will stretch when it moves from one screen to another. If you're trying to see if a 16:9 source will look okay on a 4:3 display, you can just ask your agent for the distortion ratio. It tells you exactly how many physical display pixels each source pixel covers and provides the horizontal and vertical multipliers. This saves you from pulling out a calculator to ensure visual consistency across different devices. It's especially useful when you're dealing with non-standard aspect ratios or high-resolution upscaling where the difference between a good look and a distorted one is just a few percentage points. You can find this and thousands of other tools in the Vinkius catalog to help manage your technical workflows without the manual overhead.

## Tools

### compute_stretch_factors
Calculates the specific horizontal and vertical multipliers applied during scaling. Use this to get exact dimensions for any resolution pair.

### analyze_aspect_match
Checks if two resolutions share the same aspect ratio and calculates the distortion ratio. Use this to see if a 4:3 image will look squashed on a 16:9 screen.

### calculate_pixel_footprint
Determines exactly how many physical display pixels a single source pixel covers. This is vital for calculating pixel density on custom displays.

## Prompt Examples

**Prompt:** 
```
How does a 4:3 image look on a 16:9 screen if we scale it to 1024x768?
```

**Response:** 
```
The aspect ratios do not match. The distortion ratio is approximately 1.406. This means the image will appear horizontally stretched.
```

**Prompt:** 
```
What's the stretch factor for 1920x1080 on a 4K display?
```

**Response:** 
```
The stretch factors for a 1920x1080 source on a 3840x2160 display are:
* **Horizontal:** 2.0
* **Vertical:** 2.0
```

**Prompt:** 
```
How many pixels does one source pixel cover when going from 720p to 1080p?
```

**Response:** 
```
One source pixel covers a 1.5x1.5 display pixel footprint when scaling from 720p to 1080p.
```

## Capabilities

### Calculate horizontal and vertical multipliers
Get the exact scaling numbers for any source and target resolution pair.

### Check aspect ratio matches
Identify if two different resolutions share the same proportions.

### Identify visual distortion
Find the exact distortion ratio when scaling images to mismatched screens.

### Determine pixel footprints
Calculate how many physical display pixels a single source pixel occupies.

### Analyze scaling consistency
Verify if content will look stretched or squashed on specific display types.

## Use Cases

### Broadcast Video Upscaling
A broadcast engineer needs to know how much a 720p feed will stretch on a 1080p monitor to plan for correct scaling.

### Web Asset Layout
A designer wants to know if a 4:3 hero image will look distorted on a 16:9 ultra-wide screen before finalizing a site.

### Game Display Support
A developer needs to calculate the pixel footprint for a custom 21:9 monitor to maintain consistent sharpness.

### Custom LED Wall Planning
A technician is figuring out the exact multiplier for a custom LED wall layout to ensure images don't look stretched.

## Benefits

- Stop guessing how images will scale by using analyze_aspect_match to see distortion instantly.
- Get precise multipliers for accurate layout planning with compute_stretch_factors.
- Know your pixel density for high-fidelity displays by using calculate_pixel_footprint.
- Save time on math by letting your agent handle the division while you focus on the design.
- Prevent visual errors by catching squashed content before it goes live on a different screen size.

## How It Works

The bottom line is you get exact scaling math without doing any manual division.

1. Provide the source and target resolutions to your agent.
2. Ask the agent to calculate the stretch factors or check for distortion.
3. Get a clear breakdown of the multipliers and pixel coverage.

## Frequently Asked Questions

**Can the Stretch Factor Calculator help me see if a video will be stretched?**
Yes, it calculates the exact distortion ratio between any two resolutions. This helps you see exactly how much a video will stretch or squash before you display it.

**How do I use the Stretch Factor Calculator for 4K scaling?**
Just provide the source and target resolutions to your agent. It will immediately calculate the horizontal and vertical multipliers for the 4K output.

**Does the Stretch Factor Calculator handle aspect ratio matching?**
Yes, it compares two resolutions and tells you if they share the same aspect ratio. It also provides the specific distortion ratio if they don't match.

**Can I use the Stretch Factor Calculator to find pixel density?**
Yes, it can calculate the physical footprint of a single source pixel. This is a great way to determine pixel density for custom display builds.

**Is the Stretch Factor Calculator good for broadcast engineering?**
It's perfect for broadcast work. It allows you to quickly calculate multipliers and distortion for different screen layouts and upscaling scenarios.

**What happens if I use the Stretch Factor Calculator on mismatched screens?**
It will provide the exact horizontal and vertical multipliers. This tells you exactly how the content will be distorted when scaled to the new screen size.

**What does the `compute_stretch_factors` tool do?**
It calculates the horizontal and vertical multipliers applied to a source resolution when it is scaled to a target display resolution.

**How can I check for image distortion?**
Use the `analyze_aspect_match` tool. It will tell you if the aspect ratios match and provide a distortion ratio if they do not.

**Can I calculate pixel occupancy?**
Yes, the `calculate_pixel_footprint` tool provides a human-readable description of how many display pixels one source pixel covers.
