UNICODE and non-UNICODE configurations are provided for all the libraries (thanks to Eric Jesover).Ī light version ( cximage600_lite) without the C libraries and with a small demo is provided for the first time users, or as a basic template, without the clutter of the full demo project. The class and the projects have been tested with different compilers, from Microsoft VC++6 to VC++2008, with Borland C++ Builder 3 and 6, and partially with wxDev-C++ and MinGW. 4:4:4 subsampling is useful in images with sharp edges, to reduce the typical blurring effect of the JPG compression. The next table shows the different amount of artifacts in the compressed image, using to different subsampling.

Read all?", select "Cancel").ĬxImageBMP: reads and writes 32 bit images (with alpha layer).ĬxImageICO: reads and writes Vista (PNG) icons and added support for writing multipage icons.ĬxImageSKA: new class for SKA image format, used in some video rental application.ĬxImageJPG: new options for the JPEG format subsampling ( ENCODE_SUBSAMPLE_422, ENCODE_SUBSAMPLE_444), default is 4:1:1 (high), can be set to 4:2:2 (medium) or 4:4:4 (none).

The CxImage demo implements this option, and shows how to play an animated GIF (when the program asks "File with N images. PNGs with a "pixel depth" more that 8 bits per channel will be converted down to 8 bits, this is the major limit in CxImage.ĬxImageGIF: better support for reading animated GIF, now can decode all frames in a single pass, if enabled with SetRetreiveAllFrames. The restricted features under the GPL Version 2 are disabled please read the license terms in "libdcr.h" before enabling the restricted code.ĬxImageRAW implements the basic functions to decode the image, the only available option controlled by SetCodecOption, is about the interpolation quality ( DECODE_QUALITY_LIN=0, DECODE_QUALITY_VNG=1, DECODE_QUALITY_PPG=2, DECODE_QUALITY_AHD=3).ĬxImagePNG has been improved to read and write all of the PNG_COLOR_TYPE_. LibDCR is based on Dave Coffin's dcraw.c and offers the same features of the original dcraw application (see the "dcr.dsw" project included in the \raw directory). JPEG2000 images are supported through Jasper and CxImageJAS.ĬxImage 6.00 includes a new class ( CxImageRAW) and a new library (LibDCR) to read RAW images from digital cameras common file extension are: RAW, CRW, NEF, CR2, DNG, ORF, ARW, ERF, 3FR, DCR, X3F, MEF, RAF, MRW, PEF, SR2. The j2k library (now openjpeg), and the associated class CxImageJ2K, have been removed from the project. LibTIFF 3.8.2 can be linked with CxImage, but the version included in the CxImage distribution (3.5.7, patched) can read images with OJPEG compression, or with non standard bit per samples. File Formats & Linked C LibrariesĬxImage works with the latest version of these libraries: Zlib (1.2.3), Jasper ( 1.900.1), LibMNG (1.0.10), LibPNG (1.2.24). Static methods like GetNumTypes, GetTypeIdFromName, GetTypeIdFromIndex, GetTypeIndexFromId will help the application to manage the new policy. can change the value, depending on the supported formats enabled by the corresponding CXIMAGE_SUPPORT_. An issue to take care is ENUM_CXIMAGE_FORMATS: in the old version the CXIMAGE_FORMAT_. The applications linked with the old DLL will not work with the new one but if necessary you can edit the declarations, or add new overloads, and revert to the old interface for the DLL. Here I will highlight some of the new features.Īn application written with CxImage version 5.99 should work also with the new version the interface of few methods is different, normally because of new parameters, but the default behaviour is the same. The complete list of bugfixes and enhancements is reported in the documentation, (see \doc\cximage_history.htm, or this link).

In a nutshell, this means that you can use the code however you wish, as long as you don't claim it as your own. The class CxImage is free as for the TIFF, JPEG, PNG and ZLIB libraries : "If you use this source code in a product, acknowledgement is not required but would be appreciated."ĬxImage is open source and licensed under the zlib license. Introduction & LicenseĬxImage is a C++ class that can load, save, display, and transform images in a very simple and fast way. Thank you very much to all the people that gave their contribution to this new release, with hundreds of small and big enhancements, my role was mainly to put all the pieces together.

#CHANGE A DLL FILE TO JPEG UPDATE#
Years after the previous version, I can tell that the article has survived its author, and even if my opinion on the limits of this library has not changed, an update was really necessary.
