That seems to prove the point that the original problem was that the PDF file ‘page size’ was too large to be displayed by Adobe Acrobat/Reader, and that saving the image with a higher DPI value reduces the page size without altering the image itself.mrjacoby1 wrote:Wow. It worked. Manually, anyway. DPI was at 72. I changed to 200 (Image > Set DPI) manually. Did it to both X and Y. Saving the CAL file as a PDF (FAX compression, 100% quality) generated a readable, reasonably-sized PDF file. Way to go!
Well, I’m assuming CAL images are rasterised using Ghostscript when they’re opened in XnView because they are raster images and I can’t think how else they could be rasterised... I don’t have an answer immediately but may have found some example CAL images online to test later.But .... I couldn't get those settings to "stick" with the "Tools>Options...." settings change. I changed that value to 200. Closed the software, relaunched, then opened the same CAL file. Checking its DPI, I found it was still at 72. I rechecked in "Tools>Options..." and it was at 200.
If you wish to use XnViewMP x64 you need [subject to the above qualification] to install Ghostscript x64, if you haven’t already done so, and some menu items may be different, as I partly indicated before.I cannot make this work in XnViewMP. Not even manually. 64-bit version of XnViewMP on Win 7 64-bit OS.
Please give cday's suggestion a try and run XnView as administrator.mrjacoby1 wrote:But .... I couldn't get those settings to "stick" with the "Tools>Options...." settings change.

Coincidentally, I did my own little experiments with CALSS1.RAS (8800×6800 px) & CALSS2.RAS (9400×6600 px) yesterday.cday wrote:And here's a link to some downloadable sample CAL files:

XnView can open a .RAS file?? -- the RAS file is only 2KB, so I'm obviously missing something...XnTriq wrote:Coincidentally, I did my own little experiments with CALSS1.RAS (8800×6800 px) & CALSS2.RAS (9400×6600 px) yesterday.
I don't have GhostScript installed on my system and converted these blueprints with XnView's internal PDF capabilities via Tools » Batch Processing... (Compression Type: FAX).
There are two formats supported by XnView which (can) have a .RAS filename extension: “CALS Raster” (cal,cals,gp4,mil) and “Sun Rasterfile” (ras,rast,sun,sr,scr,rs).cday wrote:XnView can open a .RAS file?? -- the RAS file is only 2KB, so I'm obviously missing something...
These samples are also available on the companion CD-ROM of O'Reilly's Encyclopedia of Graphics File Formats and can be downloaded from their servers:cday wrote:I don't know how to download those files, but I'm sure someone who posts here will...
Confirmed. I have no clue about those DCLs either.cday wrote:Thanks, it was the .DCL file that was 2KB (don't know what that is...), the .RAS opens normally in XnView.
The PDFs uploaded by me can be opened in the following programs without errors:cday wrote:So we have test CAS files, but PDF files created from them at the orignal DPI open in Adobe Reader without the issue that was the subject of this thread?
The original issue was that some CAL files opened in XnView and saved as PDF files could not be opened in Adobe Acrobat/Reader, so we don't have an example CAL file for that issue...XnTriq wrote:The PDFs uploaded by me can be opened in the following programs without errors:cday wrote:So we have test CAS files, but PDF files created from them at the orignal DPI open in Adobe Reader without the issue that was the subject of this thread?
Is that what you're asking, cday?
- Adobe Acrobat Reader v6.0.6
- PDF-XChange Viewer v2.5
- CorelDRAW v11.633
- Deneba Canvas v9.0.4
OK, but I don't have any samples for in- and output of those “wider” blueprintscday wrote:The original issue was that some CAL files opened in XnView and saved as PDF files could not be opened in Adobe Acrobat/Reader, so we don't have an example CAL file for that issue...
Acrobat User Community ([url=http://answers.acrobatusers.com/When-200-inch-page-limit-broken-q36927.aspx]When was the 200 inch page limit broken ?[/url]) wrote:200 x 200 inches is Distiller’s limit for PostScript. It’s based on the Windows printer driver limitation.
The maximum page size is 15 million inches (381 km), this is from the PDF Reference 1.6:
177. In PDF versions earlier than PDF 1.6, the size of the default user space unit is fixed at 172 inch. In Acrobat viewers earlier than version 4.0, the minimum allowed page size is 72 by 72 units in default user space (1 by 1 inch); the maximum is 3240 by 3240 units (45 by 45 inches). In Acrobat versions 5.0 and later, the minimum allowed page size is 3 by 3 units (approximately 0.04 by 0.04 inch); the maximum is 14,400 by 14,400 units (200 by 200 inches).
Beginning with PDF 1.6, the size of the default user space unit may be set with the UserUnit entry of the page dictionary. Acrobat 7.0 supports a maximum UserUnit value of 75,000, which gives a maximum page dimension of 15,000,000 inches (14,400 * 75,000 * 172). The minimum UserUnit value is 1.0 (the default).
