Code Examples

Basic Background Image Usage

The following example demonstrates how to set a background image with full opacity on the panel.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

namespace DemoApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            var panel = new SiticoneAdvancedPanel
            {
                // Enable and set a background image
                EnableBackgroundImage = true,
                BackgroundImageCustom = Image.FromFile("C:\\Images\\background.jpg"),
                BackgroundImageSizeMode = SiticoneAdvancedPanel.ImageSizeModeEx.Stretch,
                BackgroundImageOpacity = 1.0f,
                // Basic appearance settings
                TopLeftRadius = 10,
                TopRightRadius = 10,
                BottomLeftRadius = 10,
                BottomRightRadius = 10,
                BorderColor = Color.Gray,
                BorderWidth = 1.5f,
                Size = new Size(400, 300),
                Location = new Point(50, 50),
                BackColor = Color.White
            };

            Controls.Add(panel);
        }

        [STAThread]
        public static void Main()
        {
            Application.EnableVisualStyles();
            Application.Run(new MainForm());
        }
    }
}

Advanced Background with Overlay

This sample shows how to use a background image with reduced opacity and an overlay color to create a tinted effect.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

namespace DemoApp
{
    public class MainForm : Form
    {
        public MainForm()
        {
            var panel = new SiticoneAdvancedPanel
            {
                // Enable background image with custom opacity
                EnableBackgroundImage = true,
                BackgroundImageCustom = Image.FromFile("C:\\Images\\pattern.jpg"),
                BackgroundImageSizeMode = SiticoneAdvancedPanel.ImageSizeModeEx.Zoom,
                BackgroundImageOpacity = 0.7f,
                
                // Apply a semi-transparent overlay for tinting
                BackgroundOverlayColor = Color.FromArgb(100, Color.Black),
                
                // Essential styling
                TopLeftRadius = 15,
                TopRightRadius = 15,
                BottomLeftRadius = 15,
                BottomRightRadius = 15,
                BorderColor = Color.DarkGray,
                BorderWidth = 2f,
                Size = new Size(400, 300),
                Location = new Point(50, 400),
                BackColor = Color.White
            };

            Controls.Add(panel);
        }

        [STAThread]
        public static void Main()
        {
            Application.EnableVisualStyles();
            Application.Run(new MainForm());
        }
    }
}

Key Points

Aspect	Details
Visual Customization	Background Effects allow you to easily switch between image-based and solid color backdrops.
Layering Capabilities	The overlay color provides an extra layer for tinting or dimming, enhancing readability and style.
Flexible Image Handling	Various size modes (Normal, Stretch, Center, Zoom, Tile) offer flexibility for diverse design needs.

---

Best Practices

Recommendation	Explanation
Use High-Quality Images	Ensure background images are high resolution to avoid pixelation, especially when stretched or zoomed.
Optimize Image Opacity	Adjust opacity to balance visual appeal and content readability; consider using overlays for better contrast.
Test Across Devices	Validate how background images and overlays appear on different screen sizes and DPI settings.

---

Common Pitfalls

Pitfall	How to Avoid It
Overwhelming Backgrounds	Using highly detailed images without overlays can distract from the main content; opt for subtle designs.
Incorrect Sizing Modes	An unsuitable BackgroundImageSizeMode may cause image distortion; choose the mode that best fits your layout.
Performance Impact	Large background images with high opacity settings may affect performance; optimize image file sizes and dimensions.

---

Usage Scenarios

Scenario	Description
Themed User Interfaces	Use background images with overlays to match seasonal or thematic designs.
Branded Applications	Incorporate company logos or branded patterns as subtle background images to reinforce identity.
Data-Driven Dashboards	Enhance dashboards with visually appealing backgrounds that do not overwhelm the data displayed.

Additional Sections

Troubleshooting

Issue	Possible Cause	Suggested Solution
Background Image Not Displaying	The EnableBackgroundImage property might be set to false, or the image file path is incorrect.	Set EnableBackgroundImage to true and verify that the image is accessible and properly loaded.
Unintended Image Distortion	Incorrect BackgroundImageSizeMode may distort the image.	Experiment with different sizing modes (e.g., Stretch, Zoom, Center) to determine the best fit.
Overlay Not Appearing	The BackgroundOverlayColor might have an alpha value of 0, rendering it invisible.	Ensure the overlay color has a non-zero alpha component to achieve the desired tinting effect.

---

Integration Checklist

Step	Description
Enable Background Image	Set EnableBackgroundImage to true and assign a valid image to BackgroundImageCustom.
Configure Image Sizing and Opacity	Choose an appropriate BackgroundImageSizeMode and adjust BackgroundImageOpacity to achieve the desired effect.
Apply Overlay if Needed	Use BackgroundOverlayColor to add a tint or dim effect, improving contrast with foreground content if necessary.
Validate Across Themes and Resolutions	Test the background settings under different themes and screen resolutions to ensure consistent appearance.
