What's new in QPix 2.2.7
Bug fixes:
- Calling any QPix command would disable printing in 4D. This would
happen when using the Carbon version of the plug-in under Mac OS 9.x. Fixed.
- Identified and corrected a potential issue where the developer license would
not be copied to the compiled structure when building
compiled or standalone applications with 4D 2003.x.
- It was possible to crash on 4D Server when a client was logging out
if at that time the licenses dialog was open. Fixed.
What's new in QPix 2.2.6
Bug fixes:
- Under rare circumstances the plug-in could fail to load expansion
licenses on Windows. Fixed.
- Fixed a bug where the plug-in could crash after switching to another data
file with OPEN DATAFILE or CREATE DATAFILE. MacOS X only.
What's new in QPix 2.2.5
Bug fixes:
- On MacOS X QPix would fail to resolve a pathname if the name of the disk contained a
slash character ("/"). Fixed.
- In a rare case licenses installed when running under 4D Server
would not be saved. Fixed.
- Under certain circumstances QPix could cause long delays during
application startup. Fixed.
What's new in QPix 2.2.4
Bug fixes:
- When running under 4D Server on MacOS X an error dialog reporting
"no stack memory" would pop up continuously. Fixed.
- Under certain circumstances it was possible to loose installed licenses
when running under 4D Server on Windows. Fixed.
- Under certain circumstances the file selection dialog would not accept
mouse clicks when running the PPC version of the plug-in on MacOS 9. Fixed.
What's new in QPix 2.2.3
TWAIN support on MacOS X 10.2
Now that TWAIN is officially available on Jaguar, TWAIN is now opertional
in the Carbon version of QPix. Important: QPix Carbon (.4CX) supports TWAIN
on Mac OSX only. To call TWAIN on Mac OS 8/9, the classic PPC version of
QPix (.4DX) must be used, even when running with the Carbonized version of
4D (6.8.x).
Bug fixes:
- When scanning with TWAIN on Mac OS 8/9 with 4D 6.8.x and QPix.4DX
(PPC), some scanner drivers would become irresponsive to clicks and
keypresses and the user had to force-quit 4D. Fixed
- Pictures imported through 4D's clipboard on Windows are not
properly formatted. QuickTime reports a (illegal) color depth of 96 or
128 and fails on any operation involving such a pict, returning a depth
error. Interestingly, most MacOS programs cannot handle these picts
either. QPix 2.2.3 introduces workarounds and handles such picts on any
platform. Mac/Win.
- The "open image " dialog would keep some files busy after browsing.
Fixed. Mac only.
- When filtering the files to be displayed in the "open image " dialog
on Mac OS, QPix was testing if each file was a readable image by
checking the file type, filename extension, and by validating the image
with a suitable graphic importer. This filtering mechanism, although
accurate, is slow when browsing directories with lots of images on Mac
OS. The validation step is now skipped and browsing speed is back to
normal. Mac only.
- When calling a plug-in command on Windows without QT installed,
QPix might crash due to a bad check for QuickTime's presence. Fixed.
Win only.
- The product name returned by the QPx_GetVersion command now shows
whether the plugin is Carbon-based or not. For example, the Carbon
version of the plug-in will return "[plug-in name] [version] Carbon",
and the corresponding PPC version will return "[plug-in name] [version]
PPC". Mac only.
- On some localized systems (Russian, Japanese) 4D would present a
syntax error dialog during plug-in initialization and the plug-in would
fail to display the license registration dialogs. Fixed. Mac/Win.
- If 4D Client attempted to call a plug-in command when no license
seats were available on the server, the plug-in would block program
execution instead of faling back into demo mode. This is now fixed; the
plug-in will run in demo mode as expected. Mac/Win.
What's new in QPix 2.2.2
Bug fixes:
- Fixed a potential crash during startup when running with 4D 6.7.x.
- Fixed a bug that could cause long delays during startup when
running with 4D Client on Windows.
- Fixed a problem where the "Escape" menu would become unresponsive
when running with 4D Server 6.8.x on Windows.
Known issues:
- Still no TWAIN support in the Carbon version.
What's new in QPix 2.2.1
New features:
- QPix now uses the file preview mechanism built into the OS for
previewing images in the file selection dialog under MacOS X.
- Server expansions from previous installations are now automatically
detected and loaded on server startup.
Bug fixes:
- Restored the names of the TWAIN commands that were accidentally
changed in v2.2.
- Fixed a problem with the "Escape" menu on 4D Server under MacOS X
and Windows.
Known issues:
- Still no TWAIN support on MacOS X.
What's new in QPix 2.2
New features:
- Carbon version runs natively on MacOSX
- Modern plug-in area look using Appearance Manager on MacOSX/MacOS
- Revamped import/export dialogs using Navigation Services on
MacOSX/MacOS
- New license control system
Bug fixes:
- Fixed a minor memory leak in QPx_ExportImporterImage.
- Fixed a problem where pasting a picture from the clipboard into the
plug-in area would cause a -157 error (qpx_cDepthErr). Windows only.
- Implemented a workaround for some TWAIN drivers that trigger a
-29303 error (qpx_twainSourceCapErr). Windows only.
- Implemented a workaround for a Windows-only problem introduced by
the ASINTPPC.DLL that ships with 4D 6.7.3/6.8. When clicking on a menu
title the background was erased to white.
Known issues:
TWAIN support has been temporarily removed from the MacOSX (Carbon) version
because:
- The official Carbon version of the TWAIN Source Manager hasn't been
released yet.
- There aren't any MacOS X TWAIN drivers available yet (April 2002).
