CPC VIEW
SOLUTIONS
VERSION 6.0
This document describes workarounds for difficulties you might encounter.
The symptom: Automatic installation of CPC View ax fails.
The most likely explantation for this problem is that Internet Explorer is configured
to block the execution of ActiveX controls. CPC View ax is an ActiveX control; in order to use it, Internet
Explorer must be configured to allow the use of ActiveX controls.
Solution I: Change your Internet Explorer security settings
You can change the appropriate Internet Explorer security settings as follows:
- Select Internet Options... from the Internet Explorer Tools menu. This will cause
the Internet Options window to appear.
- Click the Security tab at the top of the Internet Options window. This will cause
the window to display the current security settings.
- Click the Custom Level... button at the bottom of the window. This will cause
the Security Settings window to appear.
- Scroll through the Settings section of the window and find the setting titled
Run ActiveX controls and plug-ins. This setting should be set to Prompt or Enable.
- Scroll through the Settings section of the window and find the setting titled
Download signed ActiveX controls. This setting should be set to Prompt or Enable.
Please note that if you are using Windows NT, Windows 2000, Windows XP, Windows 2003
or Windows Vista, you
also may need to be logged into an account with administrative privileges in order
to install controls such as CPC View ax directly from the Internet. (This requirement is dependent on the security
policies selected by the system administrator.) If you have configured Internet Explorer
to allow the execution of ActiveX controls and you still unable to install the control,
please try installing CPC View ax while logged into an account with administrative privileges.
Solution II: Install with the Windows Installer
Install CPC View ax with the Windows Installer rather than with Internet Explorer's automatic installation.
To install CPC View ax with the Windows Installer, download the CPC View ax
Installer
and double-click on the downloaded file (CpcViewAX.msi).
Solution III: Manual installation
Install CPC View ax manually rather than with Internet Explorer's automatic installation.
You can find CPC View ax manual installation instructions
in the online User's Guide.
The symptom: When you try to view an image file, a small multi-colored icon appears where the image should be.
The Windows registry settings for the image file type have been corrupted.
Solution: Perform a complete re-installation of CPC View ax
Perform a complete re-installation of CPC View ax,
as follows:
- Uninstall the viewer. You can find CPC View ax uninstallation instructions
in the online User's Guide.
- Restart your computer.
- Re-install the viewer. You can find CPC View ax installation instructions
in the online User's Guide.
After you have re-installed the viewer, you can test the installation by trying
to open the following addresses:
The symptom: When printing using Internet Explorer's print command (or the print button
on the Internet Explorer toolbar), the result is a blank or gray page.
Due to difficiencies in Internet Explorer's implementation of embedded multi-page documents,
printing will not work correctly if it is initiated via the native Internet Explorer user interface
(e.g., the File/Print... command; the print button on the toolbar). Under Internet Explorer,
you must initiate printing via the CPC right mouse menu.
Try the following:
- Click with the right mouse button anywhere within the CPC image window. This will cause the
CPC right mouse menu to appear.
- Select Print... from the Document sub-menu of the CPC right mouse menu. This
will cause the Select print options window to appear.
- Select the appropriate options in the Select print options window and click the OK button.
This will initiate printing.
You can find more information on CPC printing in
the online User's Guide.
The symptom: You are using Internet Explorer 7 and you are unable to open an image in a full frame window
When you try to open an image in a full browser window (or frame), Internet Explorer complains
of script errors and refuses to display the image.
Solution: Reset Internet Explorer's settings
This problem occurs on some (but not all) installations of IE 7 that were upgraded from
IE 6. It appears to be a bug in the IE upgrade process. The problem can be corrected by
resetting Internet Explorer's settings to the default settings. To reset Internet
Explorer's settings:
- Select Internet Options from IE's Tools menu. This will cause
the Internet Options window to appear.
- Click the Advanced tab at the top of the window. This will cause the window
to display advanced settings.
- Click the Reset... button in the Reset Internet Explorer settings
section of the window.
- Restart your computer.
The symptom: You are using Internet Explorer 8 and you are unable to save a remote image file
When you try to save a remote image file, the message Cannot find file. Make sure the path or
Internet address is correct appears and the document is not saved.
Microsoft has added a security setting called Protected Mode to IE8.
When protected mode is enabled, certain CPC View ax functionality is blocked by Internet Explorer.
In particular, Internet Explorer only allows ActiveX controls
to save files in a few specially designated low-security folders, such as
- <<USERPROFILE>>\AppData\LocalLow
or
- <<USERPROFILE>>\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low
Protected Mode does not allow saving
to most of the commonly used folders, such as your Desktop or My Documents.
Protected mode is enabled by default in IE8.
Solution I: Add the remote site to the Trusted Zone
Add the remote web site that contains the image document to IE's Trusted Zone as follows:
- Select Internet Options from IE's Tools menu. This will cause
the Internet Options window to appear.
- Click the Security tab at the top of the window. This will cause the window
to display security settings.
- Click the Trusted Sites label in the Select a zone section at the top
of the window. This will cause the window to display the settings for trusted sites.
- Click the Sites button. This will cause the Trusted sites window to appear.
- Enter the domain of the remote site (e.g., http://www.foobar.com) in the
Add this website to the zone text box and click the Add button.
This will add the website to the list of trusted sites.
- Click the Close button to close the Trusted sites window.
- Click the OK button to close the Internet Options window.
Solution II: Use Internet Explorer to download the file to your local disk and open the local copy
Protected mode is typically disabled for local files. Hence, you can download the remote file to
your computer and operate on the local copy without interference from Protected mode.
To download the remote file to your computer,
right-click on a link to the remote file and select Save Target As... from
the menu that appears.
Solution III: Disable Protected Mode
If you disable protected mode, you can save directly from remote files. To disable protected mode:
- Select Internet Options from IE's Tools menu. This will cause
the Internet Options window to appear.
- Click the Security tab at the top of the window. This will cause the window
to display security settings.
- Click the Internet label in the Select a zone section at the top
of the window. This will cause the window to display the settings for the Internet zone.
- Uncheck the box titled Enable Protected Mode
- Click the OK button to close the Internet Options window.
Please note that Internet Explorer will warn you that disabling protected mode
is a security risk. You can re-enable protected mode at any time, as follows:
- Select Internet Options from IE's Tools menu. This will cause
the Internet Options window to appear.
- Click the Security tab at the top of the window. This will cause the window
to display security settings.
- Click the Internet label in the Select a zone section at the top
of the window. This will cause the window to display the settings for the Internet zone.
- Check the box titled Enable Protected Mode
- Click the OK button to close the Internet Options window.
The symptom: You are using Internet Explorer 8 and you are unable to print a remote image file
When you try to print a remote image file, the message
An error occurred during this operation
appears and the document does not print.
Solution: Upgrade to the latest version of CPC View ax
You are using an old version of CPC View ax. This problem has been
corrected in later versions. To upgrade to the latest version,
click here.
The symptom: You've downloaded and saved the Netscape plugin
installation program, but when you execute it, you get the error
message
LZCreat failed
There are three possible causes for this symptom.
- You may not have closed all Netscape windows before
installing the plugin. Try closing all Netscape windows and then
reexecute the plugin installation program that you downloaded.
- The Netscape program that you are installing the CPC Viewer
for may not have a plugins directory. Check to make sure that there
is a plugins directory in the same directory as Netscape itself. (If
you installed Netscape in the standard way, the plugins directory
should be \Program Files\Netscape\Navigator\Program\plugins.) If
there is no plugins directory, create one and then reexecute the
plugin installation program that you downloaded.
- You may have downloaded the installation program into the
plugins directory itself. This may cause the same problem. Try
moving the installation program to a temporary directory before
reexecuting it.
If you have other installation problems, such as being repeatedly
prompted to install the plugin or having extra Netscape windows being
opened, you should check for these three cases as well.
The symptom: When trying to print a document from CPC View under
Netscape Communicator, the browser crashes.
This failure is dependent upon the method by which you invoke the
print command. If you invoke the print command via the standard
Netscape user interface elements (that is, "File/Print..." from
Netscape's menu or the Print button on the Netscape toolbar), Netscape
crashes immediately. However, if you invoke the print command from
the CPC View right-mouse menu, printing should work correctly.
This appears to be a regression in Communicator version 4.03 that
applies to all full page plugins; it is not CPC View specific. For
example, if you have a PDF document displayed via the Adobe Acrobat
plugin for PDF files, you will get the same crash behavior. This has
been fixed in version 4.04 of Communicator.
You can upgrade to Communicator 4.04 or, as a workaround, you
should be able to print your documents as follows:
- Right-click anywhere on the document image. This will bring up the CPC
View right-mouse menu.
- Select "Print..." from the "Document" sub-menu. This will bring up the
CPC View print dialog.
- Select the desired options from the dialog box and click on the "OK"
button.
The symptom: When you try to view a TIFF file, some other application (such as QuickTime) is loaded instead of CPC View.
Please try the following:
- Click this link
to open a CPC image in your web browser (e.g., Internet Explorer). This will
cause CPC View to be loaded.
- Click the right mouse button anywhere within the CPC image window. This will cause
the CPC right mouse menu to appear.
- Select Preferences... from the View sub-menu of the right mouse
menu. This will cause the Preferences window to appear.
- Check the box titled Check file registrations at startup at the top of
the Preferences window. This will cause the viewer to check the file
registrations each time it starts.
- Click the left mouse button anywhere outside the Preferences window to make
the Preferences window disappear.
- Hit the Reload or Refresh button on your web browser. This will
cause CPC View to be reloaded, at which point it will check and prompt you for registration
of the missing file types.
The symptom: Printing to an HP printer yields blank or partial pages.
HP acknowledges that there can be problems printing Internet
graphics on DeskJet series printers. One of the reported symptoms
is that the printer ejects a blank page. They recommend installation
of the Microsoft universal printer driver appropriate for your
printer. For most DeskJet printers, the appropriate universal driver
is the Deskjet 550C driver. Additional information can be found on the
HP web site at
http://www.hp.com/cposupport/printers/support_doc/bpd05141.html (technique 6).
Similar issues affect the HP OfficeJet Pro 1150C and 1170C series.
See
http://www.hp.com/cposupport/multifunction/support_doc/bpu01105.html
for further information.
Similar issues affect the HP LaserJet series. See
http://www.hp.com/cgi-bin/cposupport/get_doc.pl?SNI=lj&LC=printers&Tfile=bpl03541
for further information.
The symptom: CPC View displays a page in mirror-image or garbled
or banded at some magnifications, but correctly at others.
The likely cause of this problem is that you are using a Matrox
graphics card.
If you have this symptom, you can enable a simple workaround. Once
the workaround is enabled, it will remain enabled on subsequent
invocations of CPC View until such time as you explicitly disable
it. This procedure requires CPC View 4.2.4 or later.
- Bring up a CPC View window by pointing your browser to a CPC or TIFF
file.
- Set the magnification to 100%. (The image should be displayed
correctly.)
- Select the 'Preferences...' item from the 'View' sub-menu of the CPC
View right mouse menu. This will bring up the CPC View Preferences dialog
box.
- The Preferences dialog will have a checkbox labeled 'Always
reduce to 8 bits per pixel'. Check this box. This will enable the
workaround.
- Click on the main CPC View window to dismiss the Preferences dialog.
Once the workaround is enabled, imaging should work correctly.
The symptom:
You are serving TIFF or CPC documents on your web server and they
appear in a web browser as garbled text.
Your server is probably serving the documents with an inappropriate
MIME type.
You should configure your Web server to serve files with .cpi and
.cpc extensions as image/cpi, with .tif or .tiff extensions as
image/tiff, and with .pbm extensions as image/pbm. Consult the
documentation for your server to determine how to perform this
configuration.
The symptom: CPC View reports an error message "Unknown TIFF compression method".
This error message indicates that CPC View has been asked to display a TIFF image
that has been encoded using an unsupported compression method. TIFF is an
open-ended specification which allows for an infinite number of extensions.
If you attempt to view an
image stored using an unsupported compression format,
CPC View will notify you with the error message:
Unknown TIFF compression method
CPC View fully supports the TIFF 6.0 baseline reader specification. In
particular, the following TIFF compression methods are supported:
- No compression
- PackBits
- CCITT Group 3 1-Dimensional Modified Huffman run length encoding
- T4-encoding
- T6-encoding
- LZW
The symptom: CPC View reports some other error message.
The following error messages indicate that the TIFF file that you are
attempting to view is ill-formed in one way or another.
Unimplemented fill order
(N.B. Earlier versions of CPC View
provided this message for well-formed TIFF files that were not
baseline-compliant. Current versions now handle such files, so
receiving this message means that the file is actually ill-formed.)
Bad TIFF header
Bad TIFF version
Invalid TIFF File
Illegal TIFF image dimensions
Missing strip information
Short read
Corruption in TIFF image data (CCITT Group 3)
Corruption in TIFF image data (CCITT T.6)
Page number is beyond end of document
End-of-stream during bitmap read
The following error message indicates that the CPC file that you
are trying to view is ill-formed in one way or another:
Source stream exception
Page number is beyond end of document
The following error message indicates that the PBM file that you
are trying to view is ill-formed in one way or another:
Short read
Unable to read page
End-of-stream during bitmap read
The following error message indicates that the file that you are
trying to view is not recognized as a valid image file.
Unknown document format
