IMP version created using Book Designer
https://www.mobileread.com/forums/showthread.php?t=17586

Thanks!

Sure can! This is all I had to do, (the Category, Author and Title all came from that .prc):

Code:

c:\>mobi2imp.exe "Overclocked Stories of the Future Present.prc" Overclocked

I used the new mobi2imp.exe (version 4) compiled windows binaries available at https://www.mobileread.com/forums/sho...48&postcount=3 to produce a EBW 1150 .IMP version of 'Overclocked Stories of the Future Present.prc' and got good results. See Cory Doctorow - Overclocked -Future Present.imp

However, the .prc and .imp you referred to appear to have been built differently with regards to paragraph separation.

Also, that .imp file created by BD used the 'book cover' feature, and as such the 'cover' image isn't referred to in the source .html and my perl script could not add it.

However, since the 'cover' image was included in the .prc, I quickly edited the source .html to add the 'cover' as the first thing after the <BODY> tag with:

Code:

<div align="center"><p align="center"><img src="record-132.JPG" /></div>

Then, using the .opf file, I easily rebuilt it and produce a 'fixed' version. See Cory Doctorow - Overclocked -Future Present_fixed.imp

This .prc to .imp procedure is almost as good as having the original source files!!! I feel slightly voyeuristic.

This is a good reason to use a script language. You avoid all these problems with incompatible binaries.

JSWolf · 02-17-2008, 06:03 PM

So is this new fixed IMP better then thge one from Book Designer other then the font size? In other words, should I download a Windows Binary of your script to use to make the IMP version after I've made the PRC? If you say yes it is better, I'll replace my IMP version with yours for people to download.

nrapallo · 02-17-2008, 06:08 PM

Can you post another BD build of this book in .IMP format (after updating the PubUtil21.dll as per my recent tip)?

Then I will compare the two and give you my opinion.

When comparing the two .IMP versions of "Overclocked Stories of the Future Present.prc"; (1) produced by 'mobi2imp' with the 'cover' page fix, and (2) produced by you using the BD with the new PubUtil21.dll, have the following differences:

True differences:
- Cover image and interior graphics are 16 grayscale in (1) and B & W dithered in (2)
- (1) can be produced without the original 'source' files (only need .prc);

Different user selectable options:
- (1) has a small (2%) left & right margin; (2) has nomargins
- (1) has paragraphs (blank line) separation; (2) has no blank line separation

Other than the above, they use the same 'small' font size (one point larger than the previous 'x-small' BD build) for the body text. The headings look the same and one would think the books ARE the same.

Hope this helps.

By the way, I didn't ask which one you liked better?

In summary:

The original BD version produced by you uses 'x-small' font.
The revised BD version produced by you uses 'small' font.
The converted .prc produced by my 'mobi2imp' uses 'small' font.

- conversly, if '--1150' is specified, then the EBW 1150 .IMP version is NOT created.

I am just learning about POD documentation, so haven't done anything yet for 'mobi2imp'.

I updated mobi2imp.pl from version 2 (included in the Mobiperl v0.0.31 distribution) to version 6. Please include this version for any future distribution.

Things that changed:

version 4:
- Now better warns that eBook Publisher must be installed first.
- now takes switches '--1200' and '--1100' to allow for the simultaneous creation of the REB 1200 and REB 1100 versions along with the EBW 1150 .IMP version.
- conversly, if the switch '--1150' is specified, then the EBW 1150 .IMP version is NOT created.

version 5:
- now allow you to change the text one font size larger ('medium') and one font size smaller (back to 'x-small') by using '--largerfont' and '--smallerfont' respectively.
- per JSWolf's request, you can now change margins from the default (2%) to '--largemargins' (5%), '--hugemargins' (8%) and even '--nomargins' (0%)
- you can change the default text-align from justify to '--nojustify' (left aligned).
- further to Kovidgoyal's recent 'mobi2oeb' post, now can output in OEBFF (.oeb) output.
As a result, the output can be any and all at once of: '--1150' .IMP, '--1200' .IMP, '--1100' .rb and '--oeb' OEBFF!

version 6:
- per DaleDe's request, you can now change margins from the default (2%) to '--tinymargins' (2px).
- no longer requires external program (nconvert.exe); all image 'fixing' done internally by GD.pm (thanks for your suggestion here)!

To run this program, I normally use a windows batch file, like:

Code:

@echo off
rem Example batch file that can be used to procees many files at once.
rem [Category Author Title] are all optional, with same being extracted from source file.
rem ExplodeDir = . means use current directory, but not useful for multiple files.
rem add the switch --OEB, --1200, --1100 to simutaneously create these versions along with 1150 .IMP
rem add the switch --1150 to conversly not create the 1150 version
rem add the switch --nomargins, --tinymargins --largemargins, --hugemargins to set left-right margins to 0%, 2px, 5% and 8% respectively
rem add the switch --smallerfont, --largerfont, --nojustfiy to use 'x-small', 'medium' font size or no full justification
rem
rem               Source                    ExplodeDir     [Category  Author             Title]
rem               ======                    ==========      ========  ======             =====
rem perl mobi2imp.pl "Oliver Twist.prc"         Oliver      Classics "Dickens, Charles" "Oliver Twist"
rem perl mobi2imp.pl "Alice_In_Wonderland.mobi" Alice       Classics "Carroll, Lewis"   "Alice In Wonderland"
rem perl mobi2imp.pl "Alice_In_Wonderland.mobi" .
rem 
rem mobi2imp.exe --oeb  --smallerfont  "Alice_In_Wonderland.mobi" Alice
rem mobi2imp.exe --1200 --largerfont  --tinymargins    "Oliver Twist.prc"         Oliver

mobi2imp.exe SpaceEncyclopedia.mobi Space
mobi2imp.exe --smallerfont --largemargins "Alice_In_Wonderland.mobi" Alice
mobi2imp.exe --nojustify   --nomargins    "Oliver Twist.prc"         Oliver
pause

Looks like mobi2imp is really coming along. How does it do TOC processing and chapter breaks. IMP needs a <a name="toc"></a> just ahead of the toc entry in order to get the jump to TOC to work properly (a choice on the customizable button). This is a hardcoded value. (That is another tip, by the way, for editing the html0 in BD.)

Mobi2imp directly converts the .prc, so whatever TOC or chapter breaks/heading existed in the original, exist in the .imp.

I don't do any 'processing' of the HTML, only correct minor inconsistenies.

I could just add to the beginning of EVERY file:

Code:

<a name="toc"></a>

but that might BREAK any other pre-existing TOC. I'll have to think more about this.

Obvioulsy, you could choose to add it manually after using mobi2imp and double-clicking the .opf and use eBook Publisher for the manual build.

JSWolf · 02-18-2008, 01:00 PM

nrapallo... I really dislike blank lines between paragraphs, hate them with a passion. Blank lines only belong to denote a new section in a chapter, not to tell me when I've hit a new paragraph. What sort of indenting do you have? So could you program them out before I use your script to make IMP from PRC? Otherwise, I'll have to stick with Book Designer to do IMP even though otherwise your script sounds better.

Actually a missing toc entry already goes to the beginning of the file. It is only important when there is a toc present and it is not on the first page. Yes, like editing the html0 the .opf option would be a solution. I thought maybe you could detect the special mobi toc tags and just plug it in. <a name="toc" /> also works by the way.

I don't explicitly do this. If the original uses <p>..</p>, then the .IMP by default has blank lines. I think a <style> entry for <p> to avoid this would be a solution, but haven't tested this.

If the orginal uses <div>..</div>, then I'm not sure why the blank lines would be there, other than a repeat of the above cause.

Requires further exploration...

I don't have an eBookwise or Rocket eBook device. I did download and install the eBook Publisher software, which includes an IMP viewer that simulates the display on Windows. Personally, I like the smaller (x-small) font better than the "small" font. How closely does the display on the simulator match what a user will see on the actual device? Does boosting the default font size significantly improve readability?

I guess it probably depends on how old you are. The size on the screen of a pc matches in pixel count but the ppi is higher on the device than most screens. To answer your question I would need to know the ppi on your monitor. If it is less than 104 then the text on the device will be smaller.

The latest version of the tool lets you select for 3 base font sizes but the consensus of the manufacturer is that small is better which is why they changed it.
