PeachPDF 0.9.26 Release Notes

Release date: November 6, 2026
Full changelog: v0.9.25...v0.9.26
Release tag: v0.9.26

This is the last full-support release of the 0.9 series. From the first 0.10.x release (November 13, 2026), 0.9.x is in maintenance: fixes for security vulnerabilities and crashes only, on desktop and server operating systems only. See the support policy.

PeachPDF 0.9.26 adds a host-view layer on top of PeachBrackets: new HtmlView controls for WinUI, Android, macOS and iOS, backed by new Skia and CoreGraphics Canvas implementations, with animations, transitions, SMIL and scroll containers that play on a screen. For PDF output it adds PdfOperation for merging and rewriting existing PDFs, @​page bleed and marks, richer tagged PDF and a US Letter default page. Both audiences get a long list of CSS, layout, HTML parsing and SVG fixes. About 185 commits since 0.9.25 are included.

Install with dotnet add package PeachPDF --version 0.9.26.

The notes are in four parts: PeachPDF users (PDF output), PeachDrawing users (the PeachDrawing.* packages, including the PDF writer), PeachBrackets and screen users (HtmlView and HtmlDocument on a screen), and shared changes that affect them all.

For PeachPDF users (PDF output)

New

• PdfOperation merges, takes pages from, overlays, attaches to, encrypts and linearizes existing PDFs; the declarative builder can append and prepend existing PDFs. Merged documents keep links, named destinations, form fields and target-counter(..., page) correct.
• PeachDrawing.PDF gains new APIs (a standalone package): see For PeachDrawing users below.
• PDF annotation properties, including clickable attached-file icons.
• @​page bleed and marks: a page that declares them is a larger PDF page, with a TrimBox and BleedBox and crop and cross marks.
• Tagged PDF: text-only blocks are paragraphs, links carry /Contents, figures take their /Alt from aria-label and aria-labelledby, and table cells and the lang attribute are recorded. PDF/UA output is checked with veraPDF in CI.
• image-resolution and image-orientation: an image's natural size can come from the density in the file, and EXIF orientation is applied.
• mask-image: gradient and image mask layers on HTML boxes, through a PDF soft mask.
• A PdfGenerateConfig with no page size is US Letter. It used to produce a blank page.

Changes that can alter a PDF

• A closed <details> shows only its <summary>, whatever display its content has.
• <textarea> is a form control (and an interactive PDF field), and <progress> and <meter> are drawn (ten ems by one em) instead of their fallback text.
• pointer-events: none on a link writes no link annotation; accent-color tints checked controls and their PDF widget appearances.
• Page and margin box borders mitre at the corners, and @​page margins in rem use the real root font size.
• Text is its CSS size at any PixelsPerInch other than 72, and inline SVG matches the 72 rendering at other values (documents rendered at 96 may look different).
• A document with an image-resolution other than 1dppx sizes its images from the file's density.
• Fixed: the annotation collector throwing for a box that continues into another column.

For PeachDrawing users

The PeachDrawing.* packages are usable with no PeachPDF reference.

PeachDrawing.PDF (see PeachDrawing.PDF)

• Existing PDFs: PdfOperation loads a PDF from a file, stream or bytes (LoadFile, LoadStream, LoadBytes, with a password where needed) and chains MergeFile/MergeStream/MergeBytes, TakePages, OverlayFile/UnderlayFile (PdfLayerConfiguration), AddAttachment (PdfFileAttachment), ExtendMetadata, Encrypt/Decrypt/RemoveRestrictions, Linearize and WithCopyMode (PdfCopyMode.Redraw or ObjectCopy), then Save or ToArray, or AppendTo a PdfComposer. PdfPageSelector.Select parses a page selector, PdfPageSource.Open takes a password, and PdfPasswordException reports a missing or wrong one.
• Writing: PdfComposerOptions.Linearize writes a linearized (fast web view) file, PdfComposerOptions.UAConformance (PdfUAConformance.UA1 or UA2) targets PDF/UA, and PdfComposerPage.SetPrintBoxes(bleedPoints, outsidePoints) sets the TrimBox and BleedBox. PdfComposer.EmbeddedFileNames lists attachments.
• Tagged PDF: PdfTagRecorder.CheckStructure() returns structure problems as strings; OpenContentElement, OpenGroupingElement and LinkAnnotation take PdfStructureDetails (Id, Alt) and a link contents and target; PdfBookmark.StructureTarget ties an outline entry to the tag tree.
• Annotations: PdfAnnotationAppearance builds the appearance streams of free text, stamp, line, ink, outline (square or circle) and markup annotations and of icon annotations (PdfAnnotationIcon, including file-attachment icons). PdfAnnotationDefinition gains EmbeddedFileName, PopupOpen, PopupBounds, CreatedAt and ModifiedAt, and PdfFormFieldDefinition gains AccessibleName.
• Fonts: PdfRenderContext.AddFont returns a ValueTask.

PeachDrawing.Skia is new: a Canvas over SkiaSharp that draws into a surface you supply (CPU or GPU), with a switchable image codec (PeachImage, Skia's, or the default Auto). Shadows, filters, backdrop filters and conic gradients paint as GPU layer effects, and these can differ from the bitmap path by a level or two at edges. See PeachDrawing.Skia.

PeachDrawing.CoreGraphics is new: a Canvas over CoreGraphics for macOS and iOS, with CoreText or PeachDrawing.Text text, Core Image effects and ImageIO or PeachImage decoding. See PeachDrawing.CoreGraphics.

PeachPDF 0.9.26-preview1 Release Notes

Release date: November 3, 2026
Full changelog: v0.9.25-preview1...v0.9.26-preview1
Release tag: v0.9.26-preview1

This is a preview of 0.9.26. It adds three packages and a PDF operations API: PeachDrawing.Skia (a SkiaSharp Canvas) and two host views over PeachBrackets, PeachBrackets.WinUI and PeachBrackets.Android, plus PdfOperation for merging and rewriting existing PDFs. PeachBrackets itself gains a public annotation and tagging surface, hover and focus state, form control state, and an accessibility tree. It also closes a long list of CSS gaps: shape-outside, mask-image gradients, image-resolution, @​page bleed and marks, hanging-punctuation, sideways-rl/sideways-lr, the East Asian counter styles, nested column-span: all, the automatic minimum size of flex and grid items, and forced-colors painting. 155 commits are included.

Install the preview with --prerelease (or pin 0.9.26-preview1): dotnet add package PeachPDF --prerelease. The docs site is not updated for a preview.

Highlights

New packages and APIs

• PeachDrawing.Skia is a Canvas over SkiaSharp that draws into a surface you supply (CPU or GPU), usable with no PeachPDF reference, with a switchable image codec (PeachImage or Skia's). See PeachDrawing.Skia.
• PeachBrackets.WinUI and PeachBrackets.Android are an HtmlView control for each platform: pointer or touch input, hover and focus state, pointer-events, cursor, touch-action, inert, selection and links, form controls drawn and edited in place, and accessibility patterns (Narrator and TalkBack). See WinUI and Android.
• PdfOperation merges, takes pages from, overlays, attaches to, encrypts and linearizes existing PDFs; the declarative builder can append and prepend existing PDFs. Merged documents keep their links, named destinations, form fields and target-counter(..., page) correct.
• An accessibility tree (roles, names, state, table positions, focus order, live-region diffs) is built for assistive technologies, and PDF/UA output is checked with veraPDF in CI. See Accessibility.
• A PdfGenerateConfig with no page size now defaults to US Letter.

New CSS

• shape-outside and shape-margin: text follows a float's circle, ellipse, inset, polygon, path() or image shape (with shape-image-threshold).
• mask-image: gradient and image mask layers apply to HTML boxes.
• image-resolution and image-orientation: an image's intrinsic size can come from the density in the file (PeachImage 0.7.2), and EXIF orientation is applied.
• @​page bleed and marks: a larger sheet, TrimBox and BleedBox, and crop and cross marks.
• hanging-punctuation: first, last, allow-end and force-end.
• writing-mode: sideways-rl and sideways-lr for HTML and SVG text.
• East Asian longhand counter styles, such as the Chinese, Japanese and Korean numerals.
• user-select, caret-color, accent-color, cursor and pointer-events (including links inside inline SVG), and @​media, @​supports, @​container and @​layer nested inside a style rule.
• @​keyframes: a same-named rule is picked by cascade layer order, a string name is accepted, custom properties animate (discretely when unregistered, by syntax when registered), and stroke-dasharray items of different units mix as calc().
• Forced colors: the page is drawn in the system palette, gradient backgrounds are dropped and inline SVG fill and stroke take CanvasText.
• Form controls are drawn with their look for a host that shows the page, including progress bars, meters, textareas, and color, file and date/time inputs; the form-state pseudo-classes match.

Layout

• Flex and grid apply the automatic minimum size to column flex items and fr tracks, and to items a flex line grows.
• column-span: all works on a nested descendant of a multi-column container, and a float that does not fit below its column's content moves to the next column.
• Positioned boxes: an absolutely positioned box among inline content sits at its static position on the line, including in a direction: rtl parent; percentages resolve against the padding box.
• Floats: a float placed in inline flow takes its margin-top, including a negative one on a first child.
• Replaced items: no text decoration is drawn under a replaced flex or grid item.
• Tables, overflow clips, rowspan painting, ::first-line, vertical writing modes, percentage padding and offsets, and many fragmentation cases were fixed (see the full changelog).

SVG

• An inline <svg> starts from the font size of its HTML parent, takes rem from the HTML root, and px-dependent geometry follows PixelsPerInch.
• SVG animation starts from the computed value when an attribute is invalid, and initial resolves correctly for font-size, visibility, letter-spacing and word-spacing.

HTML parsing

• The parser follows the insertion modes, formatting-element (adoption agency) and foreign-content rules of the HTML standard, and font-weight: bolder/lighter resolves once on the declaring element.

Notes for upgrading

• Under forced colors, gradient backgrounds are not drawn and inline SVG paint is replaced with CanvasText; a url() background image is kept.
• A float's margin-top now affects where a float in inline flow is placed, so pages that relied on it being ignored can shift.
