Define a canvas with a gradient background, add title and author text — ready for ebook stores, print-on-demand, or preview thumbnails. ## APIs Used Image Generation (1 credits/request) ## Prerequisites You need an Iteration Layer API key. Get one at [platform.iterationlayer.com](https://platform.iterationlayer.com) during the 7-day trial. For full integration guidance (SDKs, auth, MCP, error handling), see the [Iteration Layer Integration Guide](https://iterationlayer.com/SKILL.md). ## Implementation ```bash curl -X POST https://api.iterationlayer.com/image-generation/v1/render \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "dimensions": { "width_in_px": 600, "height_in_px": 900 }, "output_format": "png", "layers": [ { "index": 0, "type": "gradient", "gradient_type": "linear", "angle_in_degrees": 180.0, "colors": [ { "hex_color": "#1B1464", "position": 0.0, }, { "hex_color": "#6C63FF", "position": 100.0, } ], "position": { "x_in_px": 0.0, "y_in_px": 0.0, }, "dimensions": { "width_in_px": 600, "height_in_px": 900, } }, { "index": 1, "type": "text", "text": "The Art of API Design", "font_name": "Playfair Display", "font_size_in_px": 52, "text_color": "#FFFFFF", "font_weight": "bold", "text_align": "center", "position": { "x_in_px": 50.0, "y_in_px": 200.0, }, "dimensions": { "width_in_px": 500, "height_in_px": 200, } }, { "index": 2, "type": "text", "text": "Alexandra Chen", "font_name": "Inter", "font_size_in_px": 24, "text_color": "#D4D0FF", "text_align": "center", "position": { "x_in_px": 50.0, "y_in_px": 750.0, }, "dimensions": { "width_in_px": 500, "height_in_px": 40, } } ] }' ``` ```typescript import { IterationLayer } from "iterationlayer"; const client = new IterationLayer({ apiKey: "YOUR_API_KEY" }); const result = await client.generateImage({ dimensions: { width_in_px: 600, height_in_px: 900, }, output_format: "png", layers: [ { index: 0, type: "gradient", gradient_type: "linear", angle_in_degrees: 180.0, colors: [ { hex_color: "#1B1464", position: 0.0, }, { hex_color: "#6C63FF", position: 100.0, }, ], position: { x_in_px: 0.0, y_in_px: 0.0, }, dimensions: { width_in_px: 600, height_in_px: 900, }, }, { index: 1, type: "text", text: "The Art of API Design", font_name: "Playfair Display", font_size_in_px: 52, text_color: "#FFFFFF", font_weight: "bold", text_align: "center", position: { x_in_px: 50.0, y_in_px: 200.0, }, dimensions: { width_in_px: 500, height_in_px: 200, }, }, { index: 2, type: "text", text: "Alexandra Chen", font_name: "Inter", font_size_in_px: 24, text_color: "#D4D0FF", text_align: "center", position: { x_in_px: 50.0, y_in_px: 750.0, }, dimensions: { width_in_px: 500, height_in_px: 40, }, }, ], }); ``` ```python from iterationlayer import IterationLayer client = IterationLayer(api_key="YOUR_API_KEY") result = client.generate_image( dimensions={ "width_in_px": 600, "height_in_px": 900, }, output_format="png", layers=[ { "index": 0, "type": "gradient", "gradient_type": "linear", "angle_in_degrees": 180.0, "colors": [ { "hex_color": "#1B1464", "position": 0.0, }, { "hex_color": "#6C63FF", "position": 100.0, }, ], "position": { "x_in_px": 0.0, "y_in_px": 0.0, }, "dimensions": { "width_in_px": 600, "height_in_px": 900, }, }, { "index": 1, "type": "text", "text": "The Art of API Design", "font_name": "Playfair Display", "font_size_in_px": 52, "text_color": "#FFFFFF", "font_weight": "bold", "text_align": "center", "position": { "x_in_px": 50.0, "y_in_px": 200.0, }, "dimensions": { "width_in_px": 500, "height_in_px": 200, }, }, { "index": 2, "type": "text", "text": "Alexandra Chen", "font_name": "Inter", "font_size_in_px": 24, "text_color": "#D4D0FF", "text_align": "center", "position": { "x_in_px": 50.0, "y_in_px": 750.0, }, "dimensions": { "width_in_px": 500, "height_in_px": 40, }, }, ], ) ``` ```go package main import il "github.com/iterationlayer/sdk-go" func main() { client := il.NewClient("YOUR_API_KEY") result, err := client.GenerateImage(il.GenerateImageRequest{ Dimensions: il.Dimensions{ WidthInPx: 600, HeightInPx: 900, }, OutputFormat: "png", Layers: []il.Layer{ il.NewGradientLayer(0, "linear", []il.GradientColor{ { HexColor: "#1B1464", Position: 0.0, }, { HexColor: "#6C63FF", Position: 100.0, }, }, il.Position{ XInPx: 0.0, YInPx: 0.0, }, il.Dimensions{ WidthInPx: 600, HeightInPx: 900, }), il.NewTextLayer(1, "The Art of API Design", "Playfair Display", 52, "#FFFFFF", il.Position{ XInPx: 50.0, YInPx: 200.0, }, il.Dimensions{ WidthInPx: 500, HeightInPx: 200, }), il.NewTextLayer(2, "Alexandra Chen", "Inter", 24, "#D4D0FF", il.Position{ XInPx: 50.0, YInPx: 750.0, }, il.Dimensions{ WidthInPx: 500, HeightInPx: 40, }), }, }) if err != nil { panic(err) } } ``` ```n8n { "name": "Generate Front Book Cover", "nodes": [ { "parameters": { "content": "## Generate Front Book Cover\n\nSelf-publishing authors and digital bookstores use this recipe to generate a professional front book cover.
