Fast, powerful 24-bit picture datatypes for AmigaOS® & MorphOS
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.x & MorphOS)

WarpDT The WarpDT package comprises of a collection of picture datatypes, and an accompanying easy-to-use preferences program. The image formats currently supported are JFIF/JPEG, PNG, TIFF, Windows BMP, PCX and PSD (Adobe Photoshop®), although support for more formats is planned. One of the key features of the datatypes is their superior decoding speed (hence the name Warp), especially on PowerPC equipped systems, and most importantly not at the expense of power and features. The datatypes have very efficient memory usage, which in particular helps 68K systems, whilst on PowerPC, AltiVec acceleration is offered on AmigaOS 4.x and MorphOS, and WarpOS users get the full benefit of combined 68K/PowerPC dual-cpu performance.

4 May 2016WarpTIFF V45.9 and WarpDTPrefs V45.9 released
It has been a long time coming, but after 5 years a new version of WarpTIFF is available, along with associated WarpDTPrefs. The changes are as follows:
  • Can now load image files conforming to the BigTIFF specification.
  • Added JPEG AltiVec speed optimizations for the OS4 and MorphOS versions making decoding speed of baseline images 1.5x faster on a G4 and 1.9x faster on a PA6T, with fancy upsampling off, on average. These optimizations can be toggled off/on using the new USE_ALTIVEC setting.
  • JPEG Huffman decoder in PowerPC versions is now 5-10% faster.
  • Applications may now configure the datatype settings via a local variable, overriding any global user settings present in ENV:.
  • Replaced usage of old Exec and Dos OS4 functions with the new ones.
  • Updated with libtiff 4.0.6, zlib 1.2.8 and jpeglib 9b.
  • OS4 version and MorphOS AltiVec code recompiled with GCC 5.2.0.
  • MorphOS and WarpOS versions recompiled with VBCC 0.9d.
22 April 2016WarpPNG V45.20 released
A new release of WarpPNG is now available, with the following changes:
  • Updated with libpng 1.6.21.
  • OS4 version recompiled with GCC 5.2.0.
20 April 2016WarpJPEG V45.13 and WarpDTPrefs V45.8 released
An updated WarpJPEG and associated WarpDTPrefs is now available, with changes as follows:
  • Added downscaling feature which allows the JPEG decoder to shrink large images down to fit the screen or a custom size, allowing huge oversized images to be loaded and displayed much faster.
  • Small additional AltiVec speed improvement.
  • Merged in changes from IJG jpeglib v9b.
  • OS4 version and MorphOS AltiVec code recompiled with GCC 5.2.0.
22 May 2015Bug Tracker + Website Updates
Some of you may have noticed subtle changes in the layout of this website over the past week... A navigation bar has been added to the top of the page, a new seperate download page and the new bug tracker where feature requests and bug reports can be made by all users.
15 May 2015WarpJPEG V45.12 and WarpDTPrefs V45.7 released
A new version of WarpJPEG and associated WarpDTPrefs is available, with updates as follows:
  • Added AltiVec speed optimizations for the OS4 and MorphOS versions making decoding speed of baseline images 1.5x faster on a G4 and 1.9x faster on a PA6T, with fancy upsampling off, on average. With fancy upsampling on, the AltiVec speed gain is even greater - 1.9x faster on a G4 and 2.3x faster on a PA6T. These optimizations can be toggled off/on using the new USE_ALTIVEC setting.
  • Huffman decoder in PowerPC versions is now 5-10% faster.
  • Reintegrated higher quality fancy upsampling smoothing feature from IJG jpeglib v6b which had not been present since WarpJPEG 45.5 due to its removal from IJG jpeglib v7 and higher.
  • MorphOS and WarpOS versions recompiled with VBCC 0.9d.
  • Added new set of benchmarks for OS4 (benchmark updates for other platforms suspended until my A1200 motherboard has been repaired).
20 February 2015WarpPNG V45.19 released
An updated WarpPNG is now available, with the following changes:
  • Updated with libpng 1.6.16.
  • MorphOS and WarpOS versions recompiled with VBCC 0.9d.
