Can This Text Hook Be Saved?

By cecilia

So, you have ImageFX version 4.xx and you still get crashes when using the Text Hook? hmmm? I may have a solution to this problem. I can't promise anything because this is a theory that hasn't been tested extensively by alot of people. But it's an idea that may help. So here we go:

When you start the Text Hook it reads the fonts in your assigned font directory and makes a simple text file with this list of fonts. IFX puts this file in Ram:ENV/ImageFX4/ and it's called "TextFontCache". This is what the top of my TextFontCache file looks like:

TextFontCache

The rest of the file just has alot more fonts listed but I think you can get the idea from this part of it. Notice the Format info. You can actually alter this file if you wish. Add fonts in other locations and that sort of thing. Now, initially, my reason for even noticing this file was that once IFX generates it, it no longer takes minutes for IFX to read your font dir every time you load up IFX's text hook. Once I've had IFX make this file I save it to my ImageFX4: dir

You can save your file anywhere but I keep it in my IFX dir just to keep things tidy. In fact, anytime I add a font and I have the Text Hook generate a new file I run a script which copies the cache file from Ram to ImageFX4:

The command in this script is:

Address Command "copy Ram:ENV/ImageFX4/TextFontCache to ImageFX4: quiet"

Now, in the ImageFX4 Icon I have added a Tooltype command which runs another script which takes the cache file and copies it TO ram:

MACRO=rexx/copyTextCacheTOram.ifx

This script (both mentioned scripts are available in the cache archive) has the reverse command:

Address Command "copy ImageFX4:TextFontCache to Ram:ENV/ImageFX4/ quiet"

You can, of course add this last command elsewhere including in your StartUp file. It's your system, do whatever works for you. The point is that whenever you start the Text hook, you won't have to wait for the generation of a new cache file. It will already be there.

Now, here we come to the next bit of Voodoo. In my fonts dir I have the usual assortment of Amiga fonts and Postscript fonts. But these days I get alot of new fonts off the internet and they are all of the TrueType variety. I put those in my Wordworth directory because that program can directly read TrueType. (I don't print stuff from my Amiga, but if I ever do, I'll be prepared!) Anyway, to convert these fonts I use ttfmanager. It's a nifty little program that easy to use! It makes a ".font" and ".otag" file for each TrueType font I install in my regular fonts dir. You, of course, are free to place these fonts in a separate dir to be tidy. This is epecially useful if you have LOADS of fonts. And remember, you can change the location of a font right in the TextFontCache file! Ah Hah!

Ok, so now we've got a bunch of cool fonts where we want them. We've got a nice list, we're all set to make make some RAD titles with IFX and BAM! The Text hook crashes big time! Whats Up!!!!

This has happened to me occassionally and I'm just as perplexed as the rest of you! After all, I beta-tested so many versions of the Text Hook my head is still swimming! And whenever I tested Amiga bitmapped fonts I never had a crash. So.....somethings up???? yes?

Well! The other day after I had installed about three or four new TrueType fonts, saved my new TextFontCache file, Blah, blah, blah. I was ready to Rock and Roll and Every One of these new fonts crashed. AAHHHHHH!!!!!! What the F@#$$% !!!!!!

I had started IFX right from boot, nothing else was running, everything was clean, and thought I had everything under control....but crash, crash, crash! So I looked at the TextFontCache file just because I couldn't think of anything else to do. And I noticed a very interesting thing. If you look at the cache.gif picture above you'll see for example that the first font, 3D has (after the "1" which means it's an Amiga font) two sizes listed - "72" and "144". But other fonts have NO SIZES listed. Look at ACharmingFont. After the "1" there is nothing. I looked at the fonts that were crashing and guess what? Go ahead, I bet you can't guess????? yep! None had sizes listed. So guess what I did next? I'll bet you can't guess. Since I had noted while I was in the Text hook what sizes I needed each font to be as I was working on it (and before they each unceremoniously crashed!) I inserted each size for each troubled font into the TextFontCache file. Now, I started the Text Hook and tried to make a text. Guess what???? (I'll bet money ya can't guess!!)) No crashing. Go figure?

I have noticed that some fonts don't mind not having sizes. But it seems that some do. I can't really explain this and I'm not Totally sure this will solve everyone's text crashes. I haven't fully tested this idea. I mean, what happens when I want to use a size that I haven't listed yet? We shall see. However, as of now, everytime I come across a font that crashes I will note if it stops crashing once a size has been indicated. I suggest you all do the same and maybe we'll finally figure out this damn mystery, already!
