GdPicture Imaging SDKs - Imaging Toolkits for developers

GdPicture Imaging SDKs are comprehensives image processing and image acquisition toolkits designed for document imaging, photo and color imaging application development.
GdPicture Imaging SDKs are delivered as ActiveX controls for integration within many development environments like Visual Basic, Visual Foxpro, Visual Studio Dotnet, MS Access, C, C++, Windev, RealBasic...

Our Toolkits offer extensive features such as image viewer control with scrollbars, thumbnail image support, image edition, annotation, image filters & effects, image format conversion, automatic border removal, automatic image deskew, image compression, image rotations & flips, TWAIN scan control, full printing support...

All GdPicture SDKs are .NET ready and work on all Microsoft windows operating system from Windows 98 SE to Windows Vista.

All GdPicture SDKs are based on the GdPicture V5 Technology which covers all mainstream areas of image capture and digital image processing:

Load, Save and Convert Image

GdPicture Technology provides features to load, save and convert images in a large variety of raster and vector formats like TIFF, GIF, JPEG, PNG, WMF, BMP, WBMP, ICO, JBG, PDF, PCX, PNM, JPEG-2000 File, JPEG-2000 codestream, HDR, Photoshop files, TARGA, JNG, EXR, DDS, PPM, SGI, PBM, PGM, XBM, XPM, KOALA, IFF, Dr. Halo files, RAW Fax G3, JBIG, Kodak PhotoCD files, Sun RAS files, camera RAW and many others...

GdPicture includes support for reading and writing bitonal, grayscale, indexed, RGB, ARGB & CMYK color image from 1-bit to 128-bits color depth.

GdPicture image encoders / decoders support the most common image data compression:

JPEG - Joint Photographic Experts Group.

OJPEG (Old JPEG 6.0 compression).

JPEG 2000 - JPEG wavelet-based image compression.

JBIG - Joint Bi-level Image Experts Group.

Packbits - lossless compression scheme for run-length encoding of data.

CCITT Group 3 Fax coding.

CCITT Group 4 Fax coding.

Modified Huffman coding.

RLE - Run-length encoding.

LZW - Lempel-Ziv-Welch

LogLuv -for high dynamic range imaging data.

Deflate.

Display

GdPicture provides full-featured and user-friendly image / PDF viewer controls wich are considered as ones of the best of the market. Our viewers include features like fast image displaying, custom viewer quality support, mouse pan tool, mouse auto-zoom tool, area selection tool, gif animation, user events catching and many other capabilites...
GdPicture also provides low-level functions which allow displaying images on any Windows handle or graphic device context.

Print

GdPicture printing support includes extended printing features like printer dialog box, printer selection, printing quality mode, printing alignment, paper tray selection and more...
You will be able to print easily image & PDF on any Windows supported printers from your applications.

TWAIN Scanning

GdPicture technology offer support for image acquisition devices like scanners, capture cards and digital cameras. With few lines of code you will be able to start single or multiple image acquisition process using a TWAIN-compliant device.
GdPicture include low-level & high-level functions allowing your application to control Automatic Document Feeder (ADF), specifies maximum image transfers, negotiate all other device features and specify image scanning attributes such as color-depth, resolution, brightness, contrast, size and more...

Document Image Processing & Editing

GdPicture SDKs includes over 350 comprehensives and sophisticated functions to provide features such as image processing, image editing, image filters, image effects, and image enhancement:

Resize & Scale.

Color anti-aliasing and smoothing for zoomed image.

Scale to gray.

Advanced merging capabilities.

Autocrop - Remove borders around a color image.

Black & White borders crop - Remove black or white borders around a bitonal image.

Area and region processing.

Blank page detection: Automatically determine if an image is blank or not.

Auto Deskew.

Standard rotations: 90°, 180°, 270°.

Mirror, flip and invert.

Angle rotation with 1/1000 degree increments.

Erode or Dilate.

Adjust contrast, brightness, gamma and saturation.

Create HQ thumbnail.

Effects and Filters including Emboss, Sharpen, Blur, Edge Detection, Noise, Soften...

Multipage TIFF Image Edition

GdPicture SDKs feature a set of high-level API to handle and edit pages in a multi-page TIFF image. These functions make it possible to access, extract, swap, insert and delete pages within a multipage TIFF image.

They also include functions to split and merge multipage TIFF files:

Merge two multi-page TIFF image into one multipage TIFF file.

Merge a jpeg file, a png file and a J2K file into one multipage TIFF file.

Extract all pages or a specific page of a multi-page TIFF image as single TIFF file(s)...

All of this can be done with a minimum of lines of code and low requirement of CPU & memory usage.

Color Depth Conversion & Color Reduction

These functions can provide image color conversion from / into a 1 bit, 4-bits, 8-bits, 16-bits, 24-bits, 32-bits, 48-bits, 64-bits and 128-bits depth.

These functions can compute the optimum color palette for a 4-bits or a 8-bits image using octree color quantization algorithms, use a standard color palette, or apply a custom or an existing color palette:

Convert a 24-bpp jpeg image into a gif image for web with optimum 8-bpp color palette.

Convert a 24-bpp jpeg photo into a 8-bpp greyscale J2K image.

Convert a 1-bpp bitonal image into a 8-bpp greyscale image.

...

Text Processing & Annotations

Text functions offer capabilities to write single line and multiple lines text including location, alignment, font family, font size, font style, text color, translucent text (watermark), angle rotation, background color which can be semi-transparent, texture text drawing and more..
