Changes in Python Imaging Library 1.1.4
Welcome to effbot.org!
PIL 1.1.4 final was released on May 10, 2003.
Alpha and beta versions of upcoming PIL releases may be found in the effbot.org downloads section.
Changes from release 1.1.3 to 1.1.4
(1.1.4 final released)
- Fixed ImageTk build problem on Unix.
(1.1.4b2 released)
- Improved building on Mac OS X (from Jack Jansen).
- Improved building on Windows with MinGW (from Klamer Shutte).
- If no font is specified, ImageDraw now uses the embedded default font. Use the “load” or “truetype” methods to load a real font.
- Added embedded default font to the ImageFont module (currently an 8-pixel Courier font, taken from the X window distribution).
(1.1.4b1 released)
- Added experimental EXIF support for JPEG files. To extract EXIF information from a JPEG file, open the file as usual, and call the “_getexif” method. If successful, this method returns a dictionary mapping EXIF TIFF tags to values. If the file does not contain EXIF data, the “_getexif” method returns None.
The “ExifTags” module contains a dictionary mapping tags to tag names.
This interface will most likely change in future versions. - Fixed a bug when using the “transparency” option with the GIF writer.
- Added limited support for “bitfield compression” in BMP files and DIB buffers, for 15-bit, 16-bit, and 32-bit images. This also fixes a problem with ImageGrab module when copying screen- dumps from the clipboard on 15/16/32-bit displays.
- Improved building on Mac OS X (from Jack Jansen).
- Added experimental WAL (Quake 2 textures) loader. To use this loader, import WalImageFile and call the “open” method in that module.
(1.1.4a4 released)
- Added updated SANE driver (Andrew Kuchling, Abel Deuring)
- Use Python’s “mmap” module on non-Windows platforms to read some uncompressed formats using memory mapping. Also added a “frombuffer” method that allows you to access the contents of an existing string or buffer object as if it were an image object.
- Fixed a memory leak that could appear when processing mode “P” images (from Pier Paolo Glave)
- Ignore Unicode characters in the BDF loader (from Graham Dumpleton)
(1.1.4a3 released; windows only)
- Added experimental RGBA-on-RGB drawing support. To use RGBA colours on an RGB image, pass “RGBA” as the second string to the ImageDraw.Draw constructor.
- Added support for non-ASCII strings (Latin-1) and Unicode to the truetype font renderer.
- The ImageWin “Dib” object can now be constructed directly from an image object.
- The ImageWin module now allows you use window handles as well as device contexts. To use a window handle, wrap the handle in an ImageWin.HWND object, and pass in this object instead of the device context.
(1.1.4a2 released)
- Improved support for 16-bit unsigned integer images (mode “I;16”). This includes TIFF reader support, and support for “getextrema” and “point” (from Klamer Shutte).
- Made the BdfFontFile reader a bit more robust (from Kevin Cazabon and Dmitry Vasiliev)
- Changed TIFF writer to always write Compression tag, even when using the default compression (from Greg Couch).
- Added “show” support for Mac OS X (from Dan Wolfe).
- Added clipboard support to the “ImageGrab” module (Windows only). The “grabclipboard” function returns an Image object, a list of filenames (not in 1.1.4), or None if neither was found.
(1.1.4a1 released)
- Improved support for drawing RGB data in palette images. You can now use RGB tuples or colour names (see below) when drawing in a mode “P” image. The drawing layer automatically assigns color indexes, as long as you don’t use more than 256 unique colours.
- Moved self test from MiniTest/test.py to ./selftest.py.
- Added support for CSS3-style color strings to most places that accept colour codes/tuples. This includes the “ImageDraw” module, the Image “new” function, and the Image “paste” method.
Colour strings can use one of the following formats: “#f00”, “#ff0000”, “rgb(255,0,0)”, “rgb(100%,0%,0%)”, “hsl(0, 100%, 50%)”, or “red” (most X11-style colour names are supported). See the documentation for the “ImageColor” module for more information. - Fixed DCX decoder (based on input from Larry Bates)
- Added “IptcImagePlugin.getiptcinfo” helper to extract IPTC/NAA newsphoto properties from JPEG, TIFF, or IPTC files.
- Support for TrueType/OpenType fonts has been added to the standard distribution. You need the freetype 2.0 library.
- Made the PCX reader a bit more robust when reading 2-bit and 4-bit PCX images with odd image sizes.
- Added “Kernel” class to the ImageFilter module. This class allows you to filter images with user-defined 3x3 and 5x5 convolution kernels.
- Added “putdata” support for mode “I”, “F” and “RGB”.
- The GIF writer now supports the transparency option (from Denis Benoit).
- A HTML version of the module documentation is now shipped with the source code distribution. You’ll find the files in the Doc subdirectory.
- Added support for Palm pixmaps (from Bill Janssen). This change was listed for 1.1.3, but the “PalmImagePlugin” driver didn’t make it into the distribution.
- Improved decoder error messages.
