Installation

composer require aimatchfun/php-runware-sdk

Basic Usage

Text to Image

use AiMatchFun\PhpRunwareSDK\TextToImage;
use AiMatchFun\PhpRunwareSDK\OutputType;
use AiMatchFun\PhpRunwareSDK\OutputFormat;
use AiMatchFun\PhpRunwareSDK\Scheduler;
use AiMatchFun\PhpRunwareSDK\RunwareModel;
use AiMatchFun\PhpRunwareSDK\PromptWeighting;

$textToImage = new TextToImage('your_api_key');

$result = $textToImage
    ->positivePrompt('A beautiful sunset over a calm ocean')
    ->height(768)
    ->width(1024)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->steps(30)
    ->cfgScale(8.5)
    ->numberResults(1)
    ->outputType(OutputType::URL)
    ->outputFormat(OutputFormat::PNG)
    ->negativePrompt('low quality, blurred')
    ->run();

Note: The negativePrompt() method is optional. You can generate images without specifying a negative prompt:

$result = $textToImage
    ->positivePrompt('A beautiful sunset over a calm ocean')
    ->height(768)
    ->width(1024)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->steps(30)
    ->cfgScale(8.5)
    ->numberResults(1)
    ->outputType(OutputType::URL)
    ->outputFormat(OutputFormat::PNG)
    ->run();

Inpainting

Inpainting allows you to selectively edit specific areas of an image by providing a seed image and a mask image:

use AiMatchFun\PhpRunwareSDK\Inpainting;
use AiMatchFun\PhpRunwareSDK\OutputType;
use AiMatchFun\PhpRunwareSDK\RunwareModel;

$inpainting = new Inpainting('your_api_key');

$result = $inpainting
    ->seedImage('59a2edc2-45e6-429f-be5f-7ded59b92046') // Image UUID or URL
    ->maskImage('5988e195-8100-4b91-b07c-c7096d0861aa') // Mask UUID or URL
    ->positivePrompt('a serene beach at sunset')
    ->negativePrompt('blur, distortion')
    ->strength(0.8) // Strength of the inpainting effect (0.0 to 1.0)
    ->maskMargin(64) // Extra context pixels around masked region (32-128)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->width(1024)
    ->height(1024)
    ->outputType(OutputType::URL)
    ->run();

Inpainting Parameters:

• seedImage(string $image): The original image you wish to edit (UUID, URL, base64, or data URI)
• maskImage(string $image): Defines the area to be modified (UUID, URL, base64, or data URI)
  • White areas (255,255,255) indicate regions to be modified
  • Black areas (0,0,0) indicate regions to preserve
  • Gray values create partial modification
• strength(float $strength): Strength of the inpainting effect (0.0 to 1.0, default: 0.8)
• maskMargin(int $margin): Adds extra context pixels around masked region (32-128 pixels)

For more details about inpainting, see the Runware Inpainting Documentation.

Image Upload

Image Upload allows you to upload images to the Runware API and receive an image UUID that can be used in other operations like inpainting. The SDK provides two methods for uploading images:

Upload from Local File Path:

use AiMatchFun\PhpRunwareSDK\ImageUpload;

$imageUpload = new ImageUpload('your_api_key');

// Upload from a local file path (automatically converts to base64)
$imageUUID = $imageUpload
    ->uploadFromLocalPath('/path/to/image.jpg')
    ->run();

// The returned UUID can be used in other operations
echo "Image uploaded with UUID: " . $imageUUID;

Upload from URL:

use AiMatchFun\PhpRunwareSDK\ImageUpload;

$imageUpload = new ImageUpload('your_api_key');

// Upload from a public URL
$imageUUID = $imageUpload
    ->uploadFromURL('https://example.com/image.png')
    ->run();

// The returned UUID can be used in other operations
echo "Image uploaded with UUID: " . $imageUUID;

Image Upload Methods:

• uploadFromLocalPath(string $path): Upload an image from a local file path. The file is automatically converted to base64 format.
• uploadFromURL(string $url): Upload an image from a public URL.
• image(string $image): Upload an image from URL, base64 string, or data URI. Automatically detects the format:
  • If starts with "http://" or "https://", treats as URL
  • If starts with "data:", treats as data URI and extracts base64
  • Otherwise, treats as base64 string

Example using image() method:

use AiMatchFun\PhpRunwareSDK\ImageUpload;

$imageUpload = new ImageUpload('your_api_key');

// Upload from URL
$imageUUID = $imageUpload
    ->image('https://example.com/image.png')
    ->run();

// Upload from base64 string
$base64Image = 'iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNk+M9QDwADhgGAWjR9awAAAABJRU5ErkJggg==';
$imageUUID = $imageUpload
    ->image($base64Image)
    ->run();

// Upload from data URI
$dataURI = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNk+M9QDwADhgGAWjR9awAAAABJRU5ErkJggg==';
$imageUUID = $imageUpload
    ->image($dataURI)
    ->run();

For more details about image upload, see the Runware Image Upload Documentation.

Examples

Image Upload Examples

Uploading from URL

use AiMatchFun\PhpRunwareSDK\ImageUpload;

$imageUpload = new ImageUpload('your_api_key');

$imageUUID = $imageUpload
    ->uploadFromURL('https://example.com/my-image.png')
    ->run();

echo "Image UUID: " . $imageUUID;

Uploading from Local File Path

use AiMatchFun\PhpRunwareSDK\ImageUpload;

$imageUUID = $imageUpload
    ->uploadFromLocalPath('/path/to/image.jpg')
    ->run();

echo "Image UUID: " . $imageUUID;

Using Uploaded Image with Inpainting

use AiMatchFun\PhpRunwareSDK\ImageUpload;
use AiMatchFun\PhpRunwareSDK\Inpainting;
use AiMatchFun\PhpRunwareSDK\RunwareModel;
use AiMatchFun\PhpRunwareSDK\OutputType;

// Step 1: Upload the image
$imageUpload = new ImageUpload('your_api_key');
$imageUUID = $imageUpload
    ->uploadFromURL('https://example.com/image.png')
    ->run();

// Step 2: Upload the mask image
$maskUUID = $imageUpload
    ->uploadFromURL('https://example.com/mask.png')
    ->run();

// Step 3: Use the uploaded images in inpainting
$inpainting = new Inpainting('your_api_key');
$result = $inpainting
    ->seedImage($imageUUID)      // Use the uploaded image UUID
    ->maskImage($maskUUID)        // Use the uploaded mask UUID
    ->positivePrompt('a beautiful blue sky')
    ->negativePrompt('blur, distortion')
    ->strength(0.8)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->outputType(OutputType::URL)
    ->run();

echo "Inpainted image: " . $result;

Inpainting Examples

Basic Inpainting

use AiMatchFun\PhpRunwareSDK\Inpainting;
use AiMatchFun\PhpRunwareSDK\OutputType;
use AiMatchFun\PhpRunwareSDK\RunwareModel;

$inpainting = new Inpainting('your_api_key');

// Simple object removal
$result = $inpainting
    ->seedImage('image-uuid-or-url')
    ->maskImage('mask-uuid-or-url')
    ->positivePrompt('white wall')
    ->negativePrompt('blur, distortion')
    ->strength(0.8)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->outputType(OutputType::URL)
    ->run();

Inpainting with Mask Margin for Enhanced Detail

// Using maskMargin to enhance facial features
$result = $inpainting
    ->seedImage('image-uuid')
    ->maskImage('face-mask-uuid')
    ->positivePrompt('a detailed face with natural lighting')
    ->maskMargin(64) // Enhances detail by zooming into masked area
    ->strength(0.8)
    ->steps(40) // Higher steps for better detail
    ->cfgScale(8.0)
    ->run();

Inpainting with Different Strength Values

$result = $inpainting
    ->seedImage('image-uuid')
    ->maskImage('mask-uuid')
    ->positivePrompt('red apple')
    ->strength(0.5) // More influence from original image
    ->run();

// High strength - complete replacement
$result = $inpainting
    ->seedImage('image-uuid')
    ->maskImage('mask-uuid')
    ->positivePrompt('blue sky with clouds')
    ->strength(0.9) // More creative deviation
    ->run();

Text to Image Generation with Different Models

use AiMatchFun\PhpRunwareSDK\TextToImage;
use AiMatchFun\PhpRunwareSDK\RunwareModel;

$textToImage = new TextToImage('your_api_key');

    ->outputFormat(OutputFormat::WEBP)
    ->run();

Using Different Schedulers

use AiMatchFun\PhpRunwareSDK\Scheduler;

// Using DPM++ 2M scheduler
$result = $textToImage
    ->positivePrompt('A beautiful landscape')
    ->scheduler(Scheduler::DPM_PLUS_PLUS_2M)
    ->run();

// Using Euler scheduler
$result = $textToImage
    ->positivePrompt('A sci-fi scene')
    ->scheduler(Scheduler::EULER)
    ->run();

// Using Karras scheduler
$result = $textToImage
    ->positivePrompt('An artistic portrait')
    ->scheduler(Scheduler::DPM_PLUS_PLUS_KARRAS)
    ->run();

Advanced Configuration

use AiMatchFun\PhpRunwareSDK\PromptWeighting;

// Using advanced settings with prompt weighting
$result = $textToImage
    ->positivePrompt('A magical forest scene')
    ->negativePrompt('blurry, low quality, distorted')
    ->height(1024)
    ->width(1024)
    ->steps(30)
    ->cfgScale(7.5)
    ->numberResults(4)
    ->outputType(OutputType::URL)
    ->outputFormat(OutputFormat::PNG)
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->promptWeighting(PromptWeighting::COMPEL)
    ->run();

    ->teaCache(true)
    ->teaCacheDistance(0.5)
    ->deepCache(true)
    ->deepCacheInterval(3)
    ->run();

Using LoRA Models

// Using multiple LoRA models with different weights
$result = $textToImage
    ->positivePrompt('A beautiful portrait')
    ->addLora('civitai:927305@1037996', 1.0)  // First LoRA with weight 1.0
    ->addLora('civitai:368139@411375', 0.8)   // Second LoRA with weight 0.8
    ->addLora('civitai:888213@486749', 0.5)   // Third LoRA with weight 0.5
    ->run();

// Using a single LoRA model
$result = $textToImage
    ->positivePrompt('A fantasy character')
    ->addLora('civitai:927305@1037996', 0.7)  // Using LoRA with weight 0.7
    ->run();

Using Custom Models

use AiMatchFun\PhpRunwareSDK\RunwareModel;

// Using a specific model version with ENUM
$result = $textToImage
    ->positivePrompt('A beautiful landscape')
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_14)
    ->run();

// Using different model variants with ENUM
$result = $textToImage
    ->positivePrompt('A portrait photo')
    ->model(RunwareModel::REAL_DREAM_SDXL_PONY_11)
    ->run();

// Using model with string directly (AIR format)
$result = $textToImage
    ->positivePrompt('A fantasy scene')
    ->model('civitai:618692@691639') // Direct AIR string
    ->run();

Note: The model() method accepts both RunwareModel enum values and string values (AIR format). This allows you to use predefined models from the enum or specify custom models using their AIR identifier directly.

Uploading LoRA Models

use AiMatchFun\PhpRunwareSDK\UploadLora;
use Ramsey\Uuid\Uuid;

$uploader = new UploadLora('your_api_key');

$result = $uploader->upload([
    'air' => 'air-of-your-model',
    'uniqueIdentifier' => Uuid::uuid4()->toString(),
    'name' => 'name-of-your-model',
    'version' => '1.0',
    'downloadURL' => 'public-url-to-your-model',
    'tags' => ['character', 'anime', 'artstyle'],
    'positiveTriggerWords' => 'positive-trigger-words',
    'shortDescription' => 'short-description-of-your-model',
    'comment' => 'comment-of-your-model'
]);

Uploading Custom Models

use AiMatchFun\PhpRunwareSDK\UploadModel;
use Ramsey\Uuid\Uuid;

$uploader = new UploadModel('your_api_key');

$result = $uploader->upload([
    'air' => 'air-of-your-model',
    'uniqueIdentifier' => Uuid::uuid4()->toString(),
    'name' => 'name-of-your-model',
    'version' => '1.0',
    'downloadURL' => 'public-url-to-your-model',
    'tags' => ['character', 'anime', 'artstyle'],
    'positiveTriggerWords' => 'positive-trigger-words',
    'shortDescription' => 'short-description-of-your-model',
    'comment' => 'comment-of-your-model'
]);

The upload methods accept the following parameters:

• air: Unique identifier for your model in the Runware system
• uniqueIdentifier: A UUID v4 string to identify your upload
• name: Name of your model
• version: Version string of your model
• downloadURL: Public URL where the model can be downloaded
