and PolyImage2 Image Processing Libraries are ActiveX
components that provide image viewing and manipulation
operations through the ImageBox and Utilities controls.
While PolyImagePro and PolyImage2 have very similar features
sets, PolyImagePro offers a higher degree of functionality
that makes it more suitable for professional level image
PolyImage Library Features:
- Color management based
upon International Color Consortium (ICC) profiles. The
ImageBox2 control offers the capability of loading and
saving ICC profiles in JPEG, JPEG 2000, PNG, PSD, and TIFF
image formats. An "auto-profile" mode is available for
processing profiles during image display, as well as manual
and proofing application of ICC profiles.
- EXIF editing capabilities
along with the capability to load and save standard and
custom EXIF information in JPEG, JPEG 2000, PSD, and TIFF
image formats. Includes a new MergeMetadata method that can
insert EXIF and IPTC information into existing files without
a decompress/compress cycle.
- IPTC editing capabilities
duplicate those of the PolyImage2 library and add the
capability of reading/writing custom information strings.
- Comprehensive support for
image processing on 16 bits per color component images. Only
a few processing routines in PolyImagePro are restricted to
8 bits per component images. Includes the new LoadImage16
method to load a 16 bits per component image contained in an
- Provides for individual
access to Red, Green, Blue, and Alpha channel data with the
GetImageChannels and LoadImageChannels methods. Access to
both 8 and 16 bit per component channel data is provided.
- Advanced resampling
filters available for image manipulation and display,
including Sinc, Lanczos, Mitchell, Cubic, and Bilinear.
- Significant load and save
time reductions for JPEG 2000 images, including very fast
reduced resolution loading for thumbnails. PolyImagePro's
JPEG 2000 processing is among the most sophisticated
- Both ActiveX and standard
DLL interfaces available from the same DLL. PolyImagePro's
entire range of image processing and display capabilities is
available without the complexities of ActiveX/COM.
