With DtpDocuments you can add instant Desktop Publishing functionality to your Delphi application!
Last changed: 15Feb2010
Current version: 2.81
Platforms: Delphi 5 - 7, 2005 - 2010

With the DtpDocuments component suite, you, the developer, can instantly add professional-quality document editing capabilities to your VCL applications.

It is not the next reporting component that can only output square, unblended shapes and text blocks. This component can handle virtually every graphical aspect, including native free rotation and alpha blending on pixel and shape level.

Example applications

DtpDocuments is used in a very diverse number of applications:

  • Photo editors

  • Word-processors

  • Desktop Publishing and home publishing applications

  • Multipage print previews

  • Process visualisation

  • Reporting engines

  • CAD/GIS editors (2D) - also eCAD, ODB++

  • Flowcharting and diagramming applications (e.g. VISIO-alike)

Features of the document

The TDtpDocument component is designed from the ground up to take away a lot of work from your hands:

  • Provide a scrollable region that visually looks like a paper page on which the user can drag, drop and edit all kinds of shapes, using mouse and keyboard. Scrolling and zooming, as well as moving shapes is super fast and completely flicker free due to smart internal caching and full usage of MMX.

  • Provide a complete multi-page document object that holds any number of pages, which are also accessible through a clickable thumbnail list.

  • Provide a complete storage mechanism to store these pages and their contents into one file. The file can also efficiently store any kind of embedded data in shapes (e.g. images), as well as user data through events.

  • Provides full cut/copy/paste for shapes and pages within the application or even between applications using the Windows clipboard.

  • Provides high-quality printing, either complete document or selections, at multiple resolutions, to a device (printer) or to an image.

  • Full undo and redo functionality is built right into the component. No need to worry about writing your own, it is already there. There is a configurable undo limit and the undo information is stored very efficiently (transaction based).

  • Positioning helpers are provided: grid, dots, or checker pattern, functions "snap to grid" and hotzone scrolling. Rotation is free by default but with StepAngle it can be configured to be done in steps.

Features of shapes

Each shape within the document inherits a wealth of properties from the basic shape (TDtpShape component). You can use the shapes that come with the component suite, which in most cases will suffise, or you can even create your own shapes based on any of the shapes provided.

  • Add all kinds of shapes to the document: text, memo, bitmaps, metafiles, polylines, line segments, rectangles, squares, ellipses, freehands, etcetera. Have a look at the shape family for an impression.

  • Each shape supports free rotation by nature. If you override a shape, you do not need to provide code for rotated drawing, this is all handled by the component.

  • Shapes can be semi-transparent, on shape level (master alpha) as well as pixel level.

  • All shapes can be grouped. Groups can be rotated and grouped again.

  • Each shape can be given a lot of different effects, among these:
    • shadow,
    • frame around shape,
    • brightness/contrast,
    • hue/saturation/lightness adjust.
    • gradients (horizontal, diagonal, from corner, from center), using colors or alpha channel, up to 3 different gradients per shape!

  • Shapes have floating point precision in contradiction to most other graphical engines that have only integer precision. The shapes can be very accurately placed and sized on the document.

  • Shapes can have hints and popup menus, special insert cursors, animation.

  • Shapes can be smartly selected because their own alpha channel is used. So you can select shapes behind other shapes through "holes" in the foremost shape.

  • Text and memo shapes can be edited in-document (even when rotated)
