The LEADTOOLS DigitalPaint C++ Class Library features are a must for anyone who wants to add digital painting functionality to an application. With LEADTOOLS Digital Paint, a developer can create an entire image editing or design application, or simply add pieces of those types of functionality into an existing application. This C++ Class Library is included with LEADTOOLS Raster, Vector, Medical, and Document Imaging products.
The LEADTOOLS DigitalPaint C++ Class Library Digital Paint includes both low-level and high-level functions for painting. With the low-level functions, you can programmatically control the painting. With the high-level functions (known as Automated Mode), you can simply turn on Automation, and allow the user to pick the painting tool. With Automation, the user's mouse events are automatically processed, and the coding is done for you.
The output can be painted to a device context (DC), a bitmap, or both. In addition, the LEADTOOLS DigitalPaint C++ Class Library provides the option of color restriction, using an optional restriction palette.
Key Features:
The LEADTOOLS DigitalPaint C++ Class Library consists of five groups of paint functions. These groups are:
Brush
The LEADTOOLS DigitalPaint brush group includes features that normally could be found only in artistic painting applications. The resulting paintbrush will be translated and scaled automatically for the device context and/or the bitmap, using user-defined transformation settings. Brush options include:
Color brush
Image/pattern brush
Diameter
Hardness/Sharpness of brush edges
Spacing - frequency of touches
Density
Opacity
Fade out - allow the brush to fade during the stroke
Texture - apply a bitmapped texture to the brush
Shape
The LEADTOOLS DigitalPaint shape group removes some of the Windows C++ Class Library programming when drawing shapes. In addition, shapes may be painted with varying degrees of opacity, or with paper texture, gradient background, etc. The resulting shapes will be translated and scaled automatically for the device context and/or the bitmap, using user-defined transformation settings. Shapes include:
Line
Rectangle
Rounded rectangle
Ellipse
Polygon
Polybezier
Region
Use the LEADTOOLS DigitalPaint region functionality to create regions for restricting image operations. Regions can range from simple to very complex (many of which are not supported by natively in Windows without LEADTOOLS). Additionally, functionality to resize or scale a region, which is not supported directly by Windows, is included with the LEADTOOLS Digital Paint C++ Class Library. The resulting regions will be translated and scaled automatically for the device context (DC) and/or the bitmap, using user-defined transformation settings. The following regions can be created:
Rectangle
Rounded rectangle
Ellipse
Polygon
Curves
Surface - a region starting at a specified point and continues in all directions that contains a specified color and tolerance
Border - a region starting at a specified point and continues in all directions until finding a specified color and tolerance
Color - a region that contains a specified color and tolerance
Fill
The LEADTOOLS DigitalPaint fill group gives the user the most complete area filling solutions for both fill method and fill features. The resulting filled area will be translated and scaled automatically for the device context (DC) and/or the bitmap, using user-defined transformation settings. Fill options and types include:
Solid
Gradient
Background tiled image
Opacity
Texture
Surface - Fills an area starting at a specified point and continues in all directions that contain a specified color and some tolerance.
Border - Fills an area starting at a specified point and continues in all directions until finding a specified color and some tolerance.
Color replace - Replaces every pixel using the current fill settings.
Text
The LEADTOOLS DigitalPaint text group includes comprehensive text drawing features that could normally only be found in a painting application. The resulting text will be translated and scaled automatically for the device context (DC) and/or the bitmap, using user-defined transformation settings. Text options include:
Font
Border
Tiled background bitmap
Alignment
Opacity
Texture
Note: LEADTOOLS DigitalPaint products do not copy data passed to a DigitalPaint function by the user. Rather, they use data directly. Therefore, the data supplied by the user must remain valid for as long as the data is needed. For example, if a palette handle is passed to a DigitalPaint function, the toolkit uses this handle to access the palette. The toolkit does NOT make a copy of the handle or the palette. Therefore, if the palette handle provided by the use is destroyed, the toolkit's palette handle is also destroyed and the toolkit will have an invalid palette handle.
Windows Common Dialogs
Includes a set of ready to use dialog boxes for gathering information for use in setting the various paint options. These allow you to quickly add code to your application for getting input from the end-user. Additionally, it gives your application a consistent Windows look and feel, making your application easier to use and learn.
Supported Environments:
The toolkit comes in Win32 and x64 editions that can support development of software applications for any of the following environments:
Windows 10
Windows 8
Windows 7
Windows Vista
Windows XP
Windows 2000
