## Description

This article demonstrates how to generate a PDF document from a collection of images located in a local folder.

## Solution

To create the PDF document, use a [FixedContentEditor](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/editing/fixedcontenteditor) which is always associated with a single [RadFixedPage](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/model/radfixedpage). The editor maintains an internal [Position](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/concepts/position) inside the page at which the image block element is inserted and drawn. The `Position` is adjusted after the image is rendered. If there is no remaining space on the page to draw the next image, a new page is created and the editor position moves to the beginning of the new page.

```csharp
        private static void GeneratePdfFromImagesWithFixedContentEditor(string imageFolderPath)
        {
            Size pageSize = new Size(Unit.MmToDip(210), Telerik.Windows.Documents.Media.Unit.MmToDip(297));
            Padding pageMarginsValue = new Telerik.Windows.Documents.Primitives.Padding(
                Unit.MmToDip(20),//left
                 Unit.MmToDip(0),//top
                  Unit.MmToDip(0),//right
                   Unit.MmToDip(0));//bottom
            RadFixedDocument fixedDocument = new RadFixedDocument();
            RadFixedPage fixedPage = fixedDocument.Pages.AddPage();
            fixedPage.Size = pageSize;
            FixedContentEditor fixedEditor = new FixedContentEditor(fixedPage);
            double currentYposition = pageMarginsValue.Top;
            double pageYLimit = pageSize.Height - pageMarginsValue.Bottom;
            string[] imageFiles = Directory.GetFiles(imageFolderPath);

            foreach (string imageFilePath in imageFiles)
            {
                Block imageBlock = new Block();
                imageBlock.SpacingAfter = 0;
                imageBlock.HorizontalAlignment = HorizontalAlignment.Center;
                FileStream fileStream = new FileStream(imageFilePath, FileMode.Open);
                var _imageSource = new Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource(fileStream);
                imageBlock.InsertImage(_imageSource);
                Size imageBlockDesiredSize = imageBlock.Measure();

                double desiredYLocationToDraw = currentYposition + imageBlockDesiredSize.Height;
                if (desiredYLocationToDraw > pageYLimit)
                {
                    //indicate the page end [optional]
                    fixedEditor.Position.Translate(0, pageYLimit - Unit.MmToDip(5));
                    fixedEditor.DrawText("END");
                    //above code is just for testing purposes

                    currentYposition = pageMarginsValue.Top;
                    fixedPage = fixedDocument.Pages.AddPage();
                    fixedPage.Size = pageSize;
                    fixedEditor = new FixedContentEditor(fixedPage);
                    //move the cursor to the beginning of the new page
                    fixedEditor.Position.Translate(pageMarginsValue.Left, currentYposition);
                }
                fixedEditor.DrawBlock(imageBlock);
                currentYposition += imageBlock.ActualSize.Height;
                fixedEditor.Position.Translate(pageMarginsValue.Left, currentYposition);
            }

            PdfFormatProvider provider = new PdfFormatProvider();
            string outputFilePath = @"..\..\sample.pdf";
            File.Delete(outputFilePath);
            using (Stream output = File.OpenWrite(outputFilePath))
            {
                provider.Export(fixedDocument, output);
            }
            Process.Start(outputFilePath);
        }
```
