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.
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.
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.
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.
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.
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
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).
v2.1.3
Fixed bug:
- The QPx_SetImporterFile command was ignoring the image path
parameter and was always returning error -43 (qpx_fnfErr) or -50
(qpx_paramErr).
v2.1.2
Fixed bugs:
- The plug-in version number did not display correctly in the file
properties window on Win2K.
- Pasting a picture into a plug-in area would trigger a
qpx_cDepthErr error (illegal color depth value) if the picture
was originally copied to the clipboard in PictureViewer or in any other
QuickTime-based app. Windows only.
- Filter menus are now disabled if no QT effects are available.
- The picture exporting routines would corrupt the exported picture
if a specific byte sequence was encountered by the end of the pict.
v2.1.1
New features:
- Added a disclosure triangle control to the Escape Product Licenses
(EPL) dialog that shows/hides the product list
- It is now possible to paste text from the clipboard in the Add
Expansion Pack dialog (cmd/ctl-v)
Fixed bugs:
- Fixed a problem introduced in 2.1 where the plug-in would not load
expansion packs from disk on Windows
- Corrected a documentation error regarding the use of the pixelDepth
parameter in the thumbnail generation commands: QPx_GetImageFileThumbnail,
QPx_GetPictureThumbnail,
QPx_GetImporterImageThumbnail
- Better handling of pictures with custom color tables (actually, a
workaround to a PICT importer bug)
v2.1
New features:
- New advanced properties dialog
- Configurable visibility of scrollbars in a scrollable area via the
QPx_SetAreaFlags command as well as via the
advanced properties dialog
- New inter-plugin api allows a single server-side window to manage
the licenses of all Escape plug-ins. Subsequent releases of all
plug-ins will also support this api.
- Reworked internal IPTC parser for better parsing of IPTC tags.
- Updated command reference manual with new commands, fixes, and new
examples
- Enhanced demo database with filtering examples using 4D slider
control to specify filter parameters.
New commands:
- Exporting images to BLOBs:
- QPx_DoExportSettingsDialog displays the export
settings dialog for a specific file type and returns the settings in a
BLOB.
- QPx_SetPictureResolution changes the
horizontal and vertical resolution of a picture variable.
- QPx_GetImporterMetaDataItem extracts
individual metadata items as BLOBs, overcoming the 32K limit of
QPx_GetImporterMetaData.
- Image area commands:
Modified commands:
- QPx_CompressPicture: a depth paramater equal
to 0 was passed directly to QuickTime and the codec would decide the
actual compression depth to use. Now QPix compresses the picture at its
original depth.
- QPx_GetImporterMetaData: the metadata text
array parameter is now optional. This allows for retrieval of only the
types of metadata items.
- QPx_ReadImporterImageInPicture renamed
to QPx_ReadImporterImageInPict because 4D 6.5+
truncates plug-in command names to 29 characters.
Fixed bugs:
- QPx_CompressPicture was
reseting picture resolution to 72 dpi on Windows.
- Some grayscale images did not display correctly because the color
table was ignored.
- Routines that return image info were reporting incorrect depth for
some grayscale images.
- In all QPx_GetXXXThumbnail commands,
color thumbnails would be generated from grayscale images if the depth
parameter was set to 0.
- Grayscale images with embedded color tables would be reported (by
QuickTime, and consequently by QPix) as color images with depth 8/4/2.
QPix now scans the color table in order to report the correct depth
(40/36/34).
- Transformed grayscale images (rotate, scale, flip) would appear
pixelated due to depth change done internally by QuickTime. QPix now is
using its own temporary pixelmap with the correct depth and color table
when necessary.
- Some routines that create pictures would create 32 bit picts out of
24 bit images (and vice versa) under certain conditions.
- Sometimes the thumbnail in the filter selection dialog was very
ugly.
- Some filters did not produce good results when applied to non-RGB
images. QPix now preserves image quality by using a temporary 32-bit
pixelmap when necessary.
- Added a workaround for a problem in the "Brightness and
Contrast" filter on Windows. The filter was producing incorrect
image colors.
- All QPx_ExportXXX commands would not set
and/or retrieve the export settings BLOB under some circumstances.
- If the user moved and/or clicked at the image preview of the
compression settings dialog, The Mac version of QuickTime would draw
over the parent window, or other areas of the screen.
- Fixed a memory leak in QPx_GetAreaPicture Mac.
- Plugged a potential memory leak in the area image filtering code.
- High ascii characters in image pathnames and metadata did not
display correctly in the image info dialog.
- QPix did not display the correct product information regarding its
license status in the design environment on 4D Client.
- The "About..." dialog of the plugin area did not display
the correct product string on 4D Client.
- Fixed a rare condition (in client/server) where QPix would start
returning -29008 (no more seats) errors if multiple processes on a
single machine were trying to acquire a seat.
- A garbage line could appear beneath or at the right of a QPix area
under certain conditions.
- All plug-in area instances were sharing a single instance of the
menu bar. This caused incorrect setup of command keys if two or more
areas had different tabability settings. Fixed.
- Static text and button labels in the APD no longer use STR#
resource references. This fixes a problem where under 6.0.x all those
refs resolved to empty strings due to some resource file weirdness.
- Fixed a bug in TWAIN acquisition where the dialog presented by a
TWAIN module would close immediately (MacOS).
- Shortcut for resuming image to normal size Cmd-0 was not working
because 4D is not passing the event to the plug-in area. Changed to
Cmd-*.
- Scrollbars were not updating properly when they were uncovered by
dialog boxes on Windows. Fixed.
- QPx_GetFilterList was swapping filter
types on Windows due to a bug in QuickTime. QPix now examines the byte
ordering of filter types and swaps the bytes if necessary.
- The "Filter..." command could trigger a crash in
QuickTime depending on the type of image being filtered (Windows).
Fixed.
v2.0
- A new plug-in area with menu bar and image-handling tools (arrow,
selection marquee, zoom tool, hand tool).
- Area appearance: correct "sunken" frame, distinctive
focus ring.
- Menu commands: import file, import URL (http/ftp/file), acquire,
get image and pixelmap information, export, revert, print, crop, select
all, flip, rotate, filter, filter again, change image size, zoom
in/out. All menu commands can also be executed procedurally.
- Area setup: procedural and by means of the advanced properties
dialog.
- Full support of clipboard operations (Cut/Copy/Paste).
- Enterability: can be controlled procedurally or by means of the
advanced properties dialog
- Full binding of an area to a 4D field: QPix 1.x would only display
picture fields while v2 automatically saves too.
- Selection of image portions: by means of marquee tool, select all,
and procedurally. Subsequent possibilities are:
cut/copy/crop/filter/invert
- Zoom (6%-1600%): by means of zoom tool, keyboard equivalents, and
procedurally.
- Full support of QuickTime filters. QT4 comes with 14 filters
including alpha gain, blur, brightness/contrast, color style, color
tint, ColorSync, edge detection, emboss, film noise, general
convolution, HSL and RGB balance, Lens flare and sharpen. Additional
filters are available from third parties.
- Procedural control of scrolling amount: allows fine positioning of
the content inside the area.
- Support for multi-image files (TIFF, Photoshop with layers,
FlashPix with many resolutions): new importer commands to retrieve the
number of images in a container and to get and set the current image
index.
- Image metadata: retrieval of textual information that is found in
some image files, including copyright, comment, software and IPTC
block.
- TWAIN Acquisition: acquire into memory using TWAIN sources. When
called from the respective area menu command, displays the acquired
image directly into the area.
- Localized plug-in versions: because QPix v2 has interface elements
that are accessible by end-users (menu commands, dialogs), national
language versions are needed. English, French, German and Japanese
localized versions are available.
