Again, sorry for the delay, very many tests had to be performed...
Well, here are the results (all on Win98SE). By 6.54 only 6.54pb2 is meant, pb3 was not tested yet.
1. About the color artifacts.
The cause of the wrong colours and of the dialog box was found: it is the EMF filter from MS Office 2000 package:
C:\Program Files\Common Files\Microsoft Shared\Grphflt\EMFIMP32.FLT
It is used only if
Use Explorer method (OLE2) checkbox on the
Settings - Thumbnails dialog box is turned on (and when either
Get from Lister plugins turned off, or when there are no plugins installed). All other tests were performed with this filter removed.
But there is still a question: why does 6.54 use this filter, while 6.53 does not?
2. About plugins.
Here are the results of viewing images without plugins and with them on two TC versions: 6.53 and 6.54pb2. There were 3 modes:
1. No plugins at all.
2. Using Imagine (0.9.0.0 - Sep 16 2005)
3. Using SGViewer (1.8.7 RC - Jan 5 2006)
In the tables below the following signs are used:
+ : image is shown correctly
– : image is not shown at all
x : plugin fails (see details below)
First,
6.53, depending of whether a plugin is used:
No plugins Imagine SGViewer
EMF–Lister + + +
WMF–Lister + + +
EMF–Thumb – + +
WMF–Thumb + + +
Then,
6.54 without plugins, depending of the WmfAllowed option:
WmfAllowed -1 0 1 2 3
EMF–Lister – – + – +
WMF–Lister – – + – +
EMF–Thumb – – – – –
WMF–Thumb – – + – +
Then,
6.54 with
Imagine installed, depending of the WmfAllowed option:
WmfAllowed -1 0 1 2 3
EMF–Lister – – + – +
WMF–Lister – – + – +
EMF–Thumb – – + – +
WMF–Thumb – – + – +
And finally,
6.54 with
SGViewer installed, depending of the WmfAllowed option:
WmfAllowed -1 0 1 2 3
EMF–Lister – –
x –
x
WMF–Lister – – + – +
EMF–Thumb – – + – +
WMF–Thumb – – + – +
By "
plugin fails" the following is meant: when trying to load the image one of two situation occurs: either
1: double error message about access violation is shown, and Lister then shows the file by itself (without the plugin), or
2: message box about fail on calling OS system function, and it cannot be closed at all, restart of TC is needed.
So, as we can see,
Lister shows the thumbnails even without plugins at all, but plugins are needed for EMF
thumbnails.
The questions for this part of tests are:
1. Why is there errors in SGViewer while in 6.53 the same SGViewer version works well?
2. Why does TC show EMF images in Lister but does not show them in thumbnails?
3. Summary.
To summarize all this post, I'll write here only problems found:
1. Using the MS Office filter by 6.54 TC version.
2. Errors while using SGViewer with EMFs in TC 6.54.
3. TC 6.53/6.54 shows EMFs in Lister (even without no plugins) but not in thumbnails.
