PDF readers for DOS (Users)

Im using win95 for PDF..

I checked long time ago pdf readers for DOS, but they require a lot of tools and conversions to read a PDF.

Exist any simple PDF reader, or this is a hard task for DOS?

Hard task. :-( Get XPDF.

PS: please drop further requests into Users rather than Announce.

PPSS: FYI: ACRO 1.0 for DOS/DOG is useless (was a 32-bit DOS app). ACRO 2.0 degraded to Win16 :clap:

Simply because now most PDF you download are newer format. I even have problem with Acrobat 6.0 (last for Win9x) that it cannot read new files. So I replaced it with Foxit reader.

Ok I haven't tried the following (nor do I have the time right now) and I also appreciate that this won't answer this request fully, however it is an idea:

I wondered if anyone has tried the GPL'd Windows command-line port of Pdftk with Japheth's HX-DOS Extender?

The Windows Pdftk binary (1 EXE + 1 DLL) can be downloaded from:

Xpdf gets the text from a pdf.

I prefer to see each page in full colour, graphics and printable.
So I use Arachne with the Ghostscript plug-in. Both local and remote files.
Once set up, it appears seamless. One click !

Then your documents are 20 years old. AFAIK it accepts PDF 1.0 well, PDF 1.1 usually well, PDF 1.2 usually badly or not at all, and anything newer definitely not at all.

Link ?

PS: Any reccommandations about standalone GhostScript binary (and how to use) ?

Look for ara-pdf.apm, where there is also a link to ghostscript.
You will need both.

There is a way to do it with ghostscript alone, I managed it once.
But the documentation is so confusing that I prefer to use the Arachne route.

Tested PDFTK,,, *and* MUPDF with HX

I just tried PDFTK in pure DOS with HX. Gave the following
errors:

dpmild32: import not found: GetHandleInformation
dpmild32: file KERNEL32.dll
dpmild32: C:\WINDOWS\SYSTEM\msvcrt.dll: cannot resolve imports

My PATH includes C:\Windows\System, and DOSLFNMS was installed
(otherwise, LIBICONV2.DLL won't load).

-----------------------------------------------------------------
Interestingly, i recently stumbled across another lightweight PDF
viewer/toolkit for Windows 32 -- MUPDF -- which i also tried out
in pure DOS with HX. It's written by Artifex, the good folks
who bring us GPL Ghostscript:

http://mupdf.com

It didn't work either, but the errors *seemed* minimal (not
really being much of a programmer and not really being too
knowledgeable about HX):

Viewer (GUI - MUPDF.EXE):

dpmild32: import not found: IsProcessorFeaturePresent
dpmild32: file KERNEL32.dll
dpmild32: d:\hx\vesa32.dll: cannot resolve imports

Tools (TUI - PDFCLEAN.EXE, PDFDRAW.EXE, PDFSHOW.EXE):

dpmild32: import not found: IsProcessorFeaturePresent
dpmild32: file KERNEL32.dll
dpmild32: D:\HX\dkrnl32.dll: cannot resolve imports

(I have the HX/HXGUI binares installed in D:\HX\ directory.)

So maybe that's another avenue to explore. It's GPL, so the
source is available. Wondering could it be hacked to work under
HX? (Beyond my abilities.)

Wouldn't it be cool to have an up-to-date PDF viewer for DOS?

Had only a quick look: The executables are looking for PF_XMMI64_INSTRUCTIONS_AVAILABLE (the SSE2 instruction set).

Hey, I cannot run MUPDF.EXE

dpmild32: import not found: GetOpenFileNameW
dpmild32: file COMDLG32.dll
dpmild32: c:\dos\win32\COMDLG32.dll: cannot resolve imports

but I can run PDFDRAW.EXE and export the pages in png and view them by image viewer. I think it may be possible to recompile tools with djgpp and modify mupdf or pdfdraw to render images though vesa routines...

SumatraPDF doesn't run too. But I can run it under Win98SE+kernelEx. It's smallest windows PDF viewer I ever seen :)

I'm trying to recompile MuPDF under DJGPP, so first started with libraries, I have done 4/5 but ended with OPENJPEG, it failed very soon :\
(there's no cczHgSkN.s in tempdir, resp. it's immediately deleted :P)

Unsurprisingly, see above.

Right ... anyone knows what (bloat) MU has what Suma hasn't ? :confused:

> I'm trying to recompile MuPDF under DJGPP, so first started with libraries

COOL :-)

BTW, I tested XPDF too, there are Win32 binaries and DGJPP binaries,
and the DGJPP binaries lack "pdftoppm.exe". Why? Font handling isn't
native, the Win32 version outsources the work to the Win32 font API.
So in HX it runs very well, just the result is "Font Blah-Bold not found"
1'000'000'000'000 times and almost empty pages saved :-(

It probably depends on built in fonts.

I need to solve the mess with djgpp headers first. I have installed latest gcc 4.5.2 but mentioned headers are not part of the package. I don't know which - djdev204? There may be some cvs updates to djdev but where is some working (tested binary) version?

I have also problems with headers that contains "#include_next" I had to comment it.

Of course there's no mupdf.exe itself coz it depends on win32 stuff but pdfdraw.exe works fine, go ahed to test it!

RayeR -

Hey. Interesting that:

1) You got the Win32 PDFDraw to work in pure DOS with HX. (I
just tried again -- no go for me, same error messages as
before.)

2) You got different dependency errors than i did for MUPDF.EXE.

I'm curious how this could be. My other HX-friendly Win32
programs seem to be working ok, but now i'm second-guessing
myself -- maybe there are some that *should* be working but
aren't.

My HX binaries directory is before C:\Windows\System (which is
the last entry) in my PATH. HXLDR32 is resident (installed from
CONFIG.SYS). No other DPMI is resident nor EMM manager (i'm
using UMBPCI instead). This is HX version 2.17 (DUSER32.DLL from
06-03-2010) with MS-DOS 7.1.

Just curious.... anyone.

Just saw the message about the graphical MuPDF -- so maybe this
note is moot. Nevertheless, i already typed it out, so here it
is anyway....

---
Ok, i've dome some preliminary work with RayeR's DGJPP PDFDraw.
It took every PDF i threw at it, and i'm impressed with it's
speed. Very nice (and quick!) work, RayeR!

I've caught a few (of those Unix-inspired) "gotcha's" in the
program (tested under 4DOS 8.0 and MS-DOS COMMAND.COM 7.1):

Options are case sensitive, as you will notice when you do the -?
help request.

However, the filename extension for the "-o" (output file) option
is *also* case-sensitive: it must be lower-case for the
png/pam/ppm/pgm specification or else nothing gets written to
disk! (Being an original PC-DOS head, stuff like this drives me
nuts! I don't realize it for awhile, and wonder why the program
doesn't work. Particularly in batch files, i like to use
capitalization to make things clearer.)

Also, with multiple-page PDF files, each succeeding output image
file will overwrite the previous, leaving only the final one on
disk. To keep them all, you need to use the %d variable in the
output-filename specification. So, for example, to save all
pages from a multi-page .PDF, you need to do something like:

pdfdraw -o out%d.png origfile.pdf

But, %d (as is) doesn't seem to work in 4DOS. You need to double
the % sign with 4DOS, as in:

pdfdraw -o out%%d.png origfile.pdf

(To reiterate, the single %d works ok with COMMAND.COM. But...
does anybody even use COMMAND.COM anymore?)

Anyway, these are just minor issues -- it's totally great to have
an up-to-date and quick way to display PDFs... in DOS... in the
year 2011! Who'd a thunk it....

- Doug B.

P.S. "Quick" meaning quicker than XPDF+Ghostscript -- making a
.PS from a .PDF using PDFTOPS (XPDF), then making an image file
from the .PS using Ghostscript, and finally displaying the image
file. Even with a batch file... slow... creaky....

You may try any of these. I think that the problem is related to pages having different resolutions (i.e. sizes), it works with all the pdfs I tried having all the pages with the same resolution.

This is CRTC register timings to set refreshrate. Probably as a human you cannot suck this numbers from a thumb but you can use GTFCALC utility where you enter resolution and refresh rate and it will thow a file with such timings :) I will include it in next release. But if you have a poor CRT don't play with it :)

> OK, I need 24 at most

you can leave 32 here it will detect if your card have 24 or 32bpp modes

Hey!!! this pdfreader is working!!!God job pal!!

Here some questions and comments:

- I testing Vs foxitreader (win95) and foxit scroll down the images faster than mupdf :( . I was testing options in the CFG file.. but nothing improves the speed.
I hope more tweaks into the program will boost the image viewing speed

-when you press the right arrow to load the next page.. the image is displayed at same position than previous one loaded. For example if you scroll down to read the end of a page and you press right arrow.. the next page is loaded and it shows the bottom of the page.

- There is a key or option into the cfg file to load the images to fit screen weight?

Its a test.. but Im amazed with the results!!! Keep the work pal!

Under pure DOS enable LFB and MTRR and use 32bpp depth if you have such VESA mode. When program exit it display last frame render time it can give you idea if changed setting led to change in performance. With LFB and set MTTRs I got ~20ms in 1600x1200/32bpp. But don't expect the same speed as your windows use HW 2D acceleration. I simply redraw entire screen everytime you scroll (+-10 pixels).

I know, it need to fix Y-offset when zoom or goto another page. Will be fixed.

No on first load I must specify some DPI but I don't know anything about image yet. When 1st page loads I can read image resolution and then adjust DPI for best fit. Yes I can do this calculation before start drawing on screen, see next update...

BTW there's short help if you press F1

IIRC, 4DOS accepts "%blah" as a shortcut to "%blah%". Also, keep in mind that normal .BATs need "%%" inside to represent "%" for syntax reasons. Try this:


@echo off
echo Hello %world
echo Hello %%world


EDIT: BTW, old MS-DOS 6.22's COMMAND.COM (unless I'm remembering incorrectly) doesn't accept %blah% on raw cmdline (outside of .BAT), but newer versions from Win9x do. At least FreeDOS' FreeCOM and 4DOS both do.

MuPDF.exe. It ran right out of the box -- i didn't need to tweak
CRT.CFG. (Intel 865G video chipset on m/b, VBE 3.0, tweaked with
VBEHz on bootup.)

Display/scroll speed is fine for me (2.8ghz P4), but i can see
how it could possibly be an issue on slower machines. I don't
think DOS can use video hardware acceleration.

F1 keypress displays a superimposed list of keyboard keys and
their functions. It fades in a few seconds without the need to
press another key.

The CRTC.CFG file has a comment line that sez: "set calculated
CRTC data for current videomode, for calc. run GTFCALC program".
"GTF" stands for "Generalized Timing Formula", a VESA standard
for CRT systems:

http://en.wikipedia.org/wiki/General_Timing_Formula

Unfortunately, the link on that page to a spreadsheet on the VESA
site that helps you calculate the params is broken. However, i
found a copy here:

www.cs.unc.edu/Research/stc/FAQs/Video/GTF_V1R1.xls

You must be messin' close to the hardware, eh?

Very impressive! A new and indispensible DOS application in 2011 that fills a real need! Kudos to you for keeping DOS alive and thriving...

This worked extremely well out of the box, on all of my systems. I even tweaked it to display PDFs in my netbook's native 1024x600 resolution (1:1 pixel mapping), but have yet to figure out the exact refresh rate timings, etc.

It has worked with every PDF I've thrown at it! What a piece of magic, and a gift for the DOS community.

The PDFCLEAN.EXE utility is wonderful. I found that a great way to archive .PDFs is to use the -ggg option combined with the -d (decompress) options and then recompress the .PDFs with 7zip (the excellent DOS port of 9.13). Saves hundreds of MBs with the much more efficient lzma compression over the default deflate algorithms used in PDFs.

One thing I'm missing is the capability to change position to a page. The Windows version has a keyboard interface ("123g" positions to page 123), but this apparently doesn't work (yet?) in the DOS port.

Hey!! each time all working better.
Fit screen and Y-offset resets nice features.

I have request for you if possible.

I was testing this new version. The pages display full screen and if I move to next pages they load fast ( ok my p166mmx need arround 150ms), but the problem comes with laptops and small screens.

If I have a small screen.. I need to zoom-in because I cannt read the page properly (tiny words)... I notice mupdf resize at extra-quality.

request: could be posible add other resize mode options for low CPU users or people that need to render each image constantly cause they display the images zoomed-in and need to scroll down very often?

I dont know if you are using lanczos/spline resize because quality is amazing... can you try to add linear,bilinear, point resize or others?. If this option is available in the cfg file users can find their best balance between speed and image quality :)

I belive it could be possible but this would require go deep inside MuPDF sources. I have no idea how they inperpolate. I think it's done during rasterization of vector fonts and graphics so the rasterizer would need to be rewritten. Main application only tell target DPI and the engine will provide pointer to target bitmat that I simply draw (internal representation is 32bit truecolor BGRA so if you have 32bpp mode it is fitted 1:1 without any recalc. If you have 24/16/8bpp mode, recalculation is needed but also output data are smaller so less PCI bus load to fill the framebuffer...)

Yes, only DOS allows me to do without any obstacles :)
VESA defines GTF and they provided that demo XLS. But I rather used some Scitech (MGL)? source that contained a routine for calculating this. It's an old source I have to find it...

Oh I understand.. change the interpolation mode have to be difficult. Each time I watch the rendered images of Mupdf I dont notice any aliasing... all the curves are perfectly smooth.. so I imagine that they are using a high quaility interpolation resize that requires extra cpu. The bpp really not affect so much to the speed.. almost similar speed at 32 or lower.

There is any other setting to change the quality of the output rendered image so maybe it can be generated/displayed faster?

I don't know yet, I'm busy with viewer, someone else may browse sources for it. I think there will be more places where the interpolation is solved, probably different for vectors, fonts and bitmaps. There are also some space to optimize used libs for decoding Jpegs, Z...

I tried to recompile MuPDF with some better optimizations, maybe help little bit
http://rayer.ic.cz/350d/mupdf_07_dos.zip
-O3 -DNDEBUG -fomit-frame-pointer -frerun-loop-opt -ffast-math -march=pentium-mmx
But I didn't rebuil all libs.
I also changed profiling debug output, you should see total render time and img blit time. I got very different numbers in 2 test case:
real PC: 25 / 24 ms (800x600/32bpp bankswitch (under XP))
DOSBox: 253 / 10 ms - so here you can see the effect of slow CPU but fast gfx.
So it would be interesting what is your ratio (low performance CPU vs low bandwith LFB transfer).
I have VESATEST log from one old Pentium 1 machine with old PCI VGA:

So this mean the most time consuming is PDF processing, displaying page is only ~10% of time... I'm thinking now that maybe I do worthless PDF page render when scrolling! I cannot check source now but when I'll be back at home... For scrolling I need just adjust y_offset and redraw the sceen. If so, it could bring heavy speed up!

You are using bank switched mode, enabling LFB should give better result.

It works fine for me. Just some questions:

Instead of an initial black screen can you output the message: "Please wait while mupdf is preparing your document" ? This improves the "user experience" for large documents. I have to wait for 10 seconds till the black screen is cleared.

Are there any plans for the support of printing the documents? Or making screenshots and save these as image files? E.g. hit CTRL-PrtScr to save the current screen as mupdf.bmp.

Maybe, I tested also some huge 80MB PDF (computer magazine) and no delay but I test on fast PC only.

I don't know how printing of graphics docs works. Maybe it would be better convert to post script and send as postscript data to printer? If you need output to graphics file use drawpdf with proper page number. But I can save bitmaps it wouldn't be problem...

Im testing with this line:

vesatest 640 480 16 lfb and yes.. the test run in LFB mode.. I get better result..

The problem is that I cannot enable LFB in my computer.. Im trying your app MTRRLFBE.EXE and I cannt enable it.

I have same problem with FASTVID. It includes a program to test LFB and yes.. the test run ok.. I got better performance in LFB than in VGA mode.. but again I cannt enable LBS for use it in all my programs

I can enable LFB in my p166mmx .. or that feature is only available for pentium pro, pentium II processors?

Maybe there's a confusion.
LFB (Linear FrameBuffer) is a feature of VESA VBE 2.0 that means entire video memory in mapped to your CPU memory address space so no need to call BIOS routines to swap small windows and other mess.

MTRRs are special registers that set caching mode for some memory area (here for LFB area) According to wiki, MTRRs are on intel Pentium Pro and newer so you cannot set it on P1MMX.

Well I looked at the black screen and thought if would hang and I would have to reboot. The PC I tested it on is five years old.

Printing (colored) graphics is quite a challenge. If you can convert to Postscript that would be an efficient way to go. The HP printer probably then just needs a command to indicate that a postscript file is send.

In the package I downloaded there was no version of drawpdf for DOS. Maybe you can make an entry under F1 of mupdf which allows to select the pages to convert to an image and then shell out to DOS and call drawpdf to make images of these pages.

Indeed! Well, here's my report, shall we begin with the bad news...?

- Your MTRRLFBE doesn't work on my AMD K7 CPU / SiS chipset system :-(
It reports about found VESA 3.0, outputs the LFB address, then tells it failed to set the MTRRs. The diagnostic is not precise enough in the absence of source code or adequate app documentation :
Are you deliberately not setting the MTRRs because, maybe, your program doesn't "know" they are present and Intel-compatible ? Or did "something" unexpected happen while trying to set the regs ? Just trying to guess...
I've been running Mtrrlfbe under HDPMI32 in case it matters.

- Your port of the MuPDF is working great out of the box ! That's the *good* (TM) news Very high image quality - and I didn't have any "tweaking" to do.

Cheers...
