TZBitmapLink allows using images or image sequences without any lines of code! Just set the FileName property to your image file and set Active to true. Following this, the image will be immediately opened. In run-time the image can be accessed via the Bitmap property.
To open a sequence of images set FileName to a mask of file names (e.g. ‘d:\images\img*.bmp’ or ‘d:\avi\*.avi’), and set the Sequence property to true. The TZImageViewer component supports a special toolbar and context menu to manage image sequences (see screenshots).

TZGraphLayer |
Up
|
|
|
With this component you can:
provide reaction of the application to mouse and keyboard messages; create a graphics layer over an image; the layer can be made active, visible or invisible
Any visualization component can have many graphics layers; each layer can implement its specific actions with image based information. All graphics layers have a common toolbar from which you can show/hide and activate/deactivate the layer; active state means that the layer can perform user’s commands. A layer can have also its own set of commands that are appended to the common toolbar and to the context menu.

|
|
|
By dropping this component onto your form, your application acquires the capabilities of a powerful vector editor.
The vector layer is a special case of TZGraphLayer, providing a CAD-like interface:
work with the following set of vector objects (or with any subset): points, polylines, polygons, rectangles, vectors, circles, ellipses; standard actions with vector objects: node insertion, node/object deletion, node/object dragging, object rotation, polyline/polygon smoothing, multiple object selection, grouping ungrouping; property dialog for customization of visual properties of the layer and its objects associate vector objects with any program objects (such as bitmaps, strings, any structures or classes);

|
|
More details
|
|
Check the RectOn property to determine if rectangle is set.
Use the ImageRect property to get the rectangle. The coordinates of the rectangle returned by ImageRect are always clipped by the image dimensions. Use this property to set a new rectangle from a program. Use the SelectAll button/ context menu item/ function to set a rectangle containing a whole image.
|

|
|
TZRegionLayer |
Up
|
|
|
This is a particular case of TZMarkerLayer. This component is suitable for implementation of region selection tools. The user can use the following vector objects to create a region: polygon (smoothed or not), rectangle, circle and ellipse.

Once the object is created by the user the HRGN Windows object is available; it can be accessed via the Region property. Any change of the object causes recreation of the region. Check the property RegionOn to determine if the region exists. To check if an image pixel belongs to the region, the standard Windows API function PtInRegion(Region,X,Y) can be used.

TZGraph3DBox |
Up
|
|
|
This is a component for visualization of 3D-graphics:
- does not use OpenGL or Direct3D
- contains procedure to draw in 3D world coordinates
- surface drawing with hidden parts removal
- contains many events for response to 3D-view changing
Use this component to represent simple 3D-plots. If you are going to allow the user to change the 3D-view parameters intensively at run-time, then it is better to use TZ3DViewer, which was designed specially for this purpose.

TZ3DViewer |
Up
|
|
|
This is a complex component consisting of TZGraph3DBox and navigation toolbar. This component is a convenient tool for manipulating 3D-plots. The navigation toolbar allows viewing at different angles and distances.
|

|
|
|
|
More details
|
|
The component is implemented as a standard TFrame component containing a set of TSpeedButtons and a TZGraph3DBox component. The latter can be accessed via the SurfaceGraphWindow property.
When the user changes the 3D view using the navigation buttons, the OnChanging event occurs. Using this event, the program can provide a visual feedback of view changing. For example, instead of redrawing a full 3D-plot which may be time consuming, the program can draw just the 3D-axes. The OnPaint event is usually used to completely redraw a 3D view. The boolean property MoveSurfaceAxes indicates whether the 3D view is changing.

TZThumbNavigator |
Up
|
|
|
In many cases it's preferable to quickly view some set of images. TZThumbNavigator allows you to do that, allowing the user to select any image from the list with the mouse. A developer can provide special actions when an image is selected or deselected. There is also the built-in capability to automatically visualize a selected image at any resolution.
TZThumbNavigator can be considered as a viewer for TZBitmapLink objects. This means that each TZThumbNavigator can visualize thumbnail versions of:
Also the component can visualize:
- ROI-based images (many small images inside a large one)
- undo/redo lists

 TZVideoLink
|
Up
|
|
|
TZVideoLink is a component for video capture from video sources.
TZVideoLink is a descendant from TCustomBitmapLink class. This ensures the compatibility with other components of the library (TZImageBox, TZStereoBox, TZImageViewer, TZThumbNavigator, TZRasterLayer).
TZVideoLink captures a bitmap from a video source and stores it to the TZDataBitmap object. The queue of the previous bitmaps is kept also. This can be useful for many video processing tasks where previous frames should participate in processing.
The developer has flexible control over the component:
can set any pixel format of the captured bitmap (1,4,8 - grayscale and color, 15,24,32-bit color). The captured frame is automatically converted to this pixel format. can set the length of the bitmap queue. can handle the following events: can switch between video sources; can access to control panels supported by video drivers

|
|
More details
|
|
TZVideoLink and TZBitmapLink have the same ancestor, so video capture can be seamlessly integrated into an application if it uses TZBitmapLink component.
