issues with Ruffle with SWF files from SWFTools
I have reported some issues in Ruffle with SWF files generated with SWFTools (swfc and pdf2swf).
I wonder whether it would be possible to get an explanation of what SWFTools might be doing in a different way, if I reported some issues that I encounter in Ruffle with SWF files that I generated with SWFTools.
Many thanks for your help.
I thought this was the best way to contact him, since this repository belongs to him.
@matthiaskramm, many thanks for your reply.
Using pdf2swf from SWFTools, I generate both SWF files:
BTW, files aren’t compressed. I only appended the .zip extension to attach them here.
Both files are generated using pdf2swf contained in SWFTools version 0.9.2, from a PDF document with embedded fonts which contains only a subset of used characters.
The file noproblem.swf is displayed fine and it is generated with pdf2swf -f.
The file problem.swf doesn’t have all characters displayed (generated without any -f option).
My question is: which font information is removed when not using pdf2swf -f?
Another issue comes from https://github.com/ruffle-rs/ruffle/issues/1561#issuecomment-748651396.
The loader doesn’t work because it’s located inside a sprite.
My question would be how to use a loader outside the sprite (since Ruffle isn’t able to solve the value inside a sprite).
Sorry, I need to elaborate more on this, but right now I’m afraid I don’t have the time for this.
Many thanks for your help.
Regarding the fonts, I remember that pdf2swf will clear unused glyphs, but leave them in the font table, thus generating empty polygons. Maybe that's what's tripping up Ruffle.
Many thanks for your reply, @matthiaskramm.
The diff from swfdump -D from both files (pdf2swf with and without -f) reads:

It seems to be that pdf2swf -f keeps the space character, while pdf2swf doesn’t.

Sorry, but I think that pdf2swf removes two tables and other data from the font.
Do you have more information about that?
With https://www.mejorar-presentaciones.tk/mejorar-presentaciones-presentation.swf, the main sans font isn’t displayed at all.
The error message reads:
Error running definition tag: DefineFont3, got Invalid data: Invalid fill style. player.js:1:25123
Fonts in that SWF file are numbered from 2 to 7. The main sans font from the first slide is object 4 and the monospaced font is object 5.
Do you know which fill styles are using font 0004 and font 0005?
Many thanks for your help again.
@matthiaskramm, Ruffle has problems with loading movieclips inside sprites.
I have the following basic swfc source;
.flash filename="box.swf"
.box b1 100 100 color=red fill=yellow
.put b1 pin=center scale=0%
.frame 100
.change b1 pin=center scale=100%
.frame 200
.change b1 pin=center scale=0%
.end
And here you have the loader:
.flash filename="sprite-loader.swf" version=7 fps=12
.box placeholder width=1024 height=768
.frame 1
.box b1 500 500 color=yellow fill=red
.put b1 pin=center scale=100%
.sprite images
.put placeholder alpha=0%
.action:
the_presentation = "box.swf";
first_loading = new Object();
first_loading.onMouseDown = function () {
load_swf = new MovieClipLoader();
load_swf.loadClip(the_presentation, placeholder);
};
Mouse.addListener(first_loading);
.end
.end
.action:
this.attachMovie("images","whatever",this.getNextHighestDepth());
.end
.end
Is there any way to display the movieclip avoiding the sprite? Ruffle has problems to resolve placeholder because of the sprite.
Many thanks for your help.
Sprite is As3, so nothing to do with your code which is in As2. I suggest you open an issue at Ruffle git repo as it's not a swftools issue.
Many thanks for your reply, @ROBERT-MCDOWELL.
I didn’t know that sprites were AS3.
The issue was opened some time ago in Ruffle, but it will take some time to get solved.
I had found another approach to the loader:
.flash filename="sprite-loader.swf" version=7 fps=12
.box placeholder width=1024 height=768 fill=red
.button mybutton
.show placeholder alpha=5%
.on_release inside:
the_presentation = "./box.swf";
this.loadMovie(the_presentation, this.placeholder);
.end
.end
.frame 1
.box b1 500 500 color=yellow fill=red
.put b1 scale=100%
.put placeholder alpha=5%
.put button1=mybutton
.end
Many thanks for your help.
Glad you find a solution!! Ruffle started 2 years ago only, and constantly need developers to join the community to speed up Flash API and AVM covering. Spread the message!
