Mother of all shapes
The mother of all shapes is the TdtpShape object. It does not represent any real shape yet but for clarity, let's visualise this shape as a little purple goat:
This shape can be resized, moved, and rotated freely. It can also be made semi-transparent, as can be seen above when put over a rock image. Since all these properties are defined on this level, they will be available for each shape that inherits from this object!
Effects
Also on this level, we can already assign effects to the shape. There are a number of effects:
|
Shadow
|
Traditional shadow |
Configured as a glow |
On a background it blends in.. |
|
Frames
|
A frame can be placed around any shape. |
It rotates with the shape, and can be filled, and can have rounded corners |
..and combine shadow and frames! Note that the fill can be transparent too. |
|
Color adjustments
|
Original colors |
Brightness and contrast adjusted |
Hue, Saturation and Lighting adjusted. |

Family tree
The family tree extends with these descending shapes:
Thanks to the object-oriented nature, all shape types inherit the properties from the ancestor, so each shape can rotate, be blended, have frames, shadows, color corrections, etcetera. Additionally here are some key properties per shape type:
Text shapes
These shapes can have any font that can be rendered in Windows and can be edited in-document if you use a TrueType font. Text shapes can be left or right justified or centered.
Multiline shapes
These shapes can also be edited in-document, and will automatically wordwrap (default option). Note that with the frame option these make nice text boxes.
Bitmap shapes
The library supports these type of bitmap file formats:
| · | Windows Bitmap (BMP)
|
| · | Jpeg Images (JPG)
|
| · | GIF Images
|
| · | PNG Images
|
Bitmaps always have RGBA channels and are 32 bits in DtpDocuments
Metafile shapes
The library supports Windows Metafile and Enhanced Metafile. The Metafile shape can override the color and line settings of the metafiles.
