Any idea when the recording of this session will be uploaded?

Set ramdisc size to 500 MB.

The RAM disc size limit on RISC OS 5.3x is 2GB.

I also tried a magazine that has well over 200 pages. (Special double-length issue as a ‘historic’ issue.) I tend to put input and output on RAMDisc for speed and to avoid accidentally over-writing something else. Set ramdisc size to 500 MB.

The problem that showed up is that the series of individual output files filled up the ramdisc and then couldn’t finish all the pages! When I looked it seems to create both a jpeg and a one-page PDF for each page.

So is it possible to have the individual 1-page jpegs be delected once eacn one gets the accompanying output pdf of that page? This should mean I can try out the big issues with many pages.

Ta!

YES! A coconut at last! :-)) I tried using the global setting to get the larger ‘Next’ space, and DeBrown did, indeed then ‘de brown’ a chosen file.

Took time on my old machine, but I do have a new one that’s faster when I want to process a set of magazines.

The input test file has text which isn’t truely black, but grey. And the output is also like that. I’ll experiment with other files, but wonder if the use of ImageMagic and perhaps more levels would help this? (IIUC its using 4 levels for the output.)

I’ll try a few more files. Maybe I should also learn more about ImageMagik, etc…

THANKS. :-)))

Want to check: What ‘tasks’ setting do you mean? The one listed when I do a click of the mouse over the icon at the right-hand end of the icon bar? That seems a bit ‘shotgun’ if it also means other things I may start get a large allocation. I’d thought each app could specify what it needs in its !Run. But it is ages since I wrote anything close to a desktop app, so this may be another example of my curren clue-free state of mind, (sic)

The version I have says it is 7.1.1-17. Is that likely to make any difference to the above? I suspect I?m simply not yet ?getting it right? in terms of some setting or whatever?

After adjusting the ‘Next’ size in ‘Tasks’ DeBrown processed a PDF file successfully.

There is only one language, English.
I can almost understand in real time.

I use the translators for Risc Os documents, but it always requires a good proofreading and corrections.
I opted for this solution because I make misunderstandings in my interpretation of the manuals.

The app now runs… but gives no real output.

A small filesized input pdf gave a blank single file out.

A bigger one also did that but claimed there wasn’t enough free space. Said that 29526k was needed. But the machine says it has 1371240k free!

For a matter of interest – how well does the French translation go?

More to the point, I do now but don’t have ImageMagick 7 installed.

The latest version of ImageMagick 7 (7.1.2-25) is available from here. This version also works with RPCEmu.
