Sometimes chapters are packaged in PDF

[ghost]

Hi, i prefer to leave my manga in PDFs. Sometimes a chapter gets downloaded, it doesnt compress it into PDF but it says as a folder of pictures.

Is there a reason for this? Anyway I can fix it?

[riderkick]

Probably your download is incomplete.

[ghost]

Well it goes like this;

Chapter 1.pdf

Chapter 2 (folder)

Chapter 3.pdf

Why would it start the chapter 3 download before finishing Chapter 2?

Thanks for the response btw

[riderkick]

Probably there is an error while downloading chapter 2(some images can't be download), so it will continue to chapter 3. But it should show "Failed" if there is some failed chapter.

[ghost]

Is there a log or something that I can send you? Cause as far as I know everything is download successfully.

[riderkick]

How if you only download one chapter that is not compressed to pdf?

There's is no log if there is no error. Tell me exactly what you're trying to download. Title, website, chapter. I'll check it.

Just tested this, seems to not work still.

I was downloading Chihayafuru Chapter 90 on MangaStream. It might work if I try other sites, but those others sites don't always download everything into pdfs either.

On 0.9.15.0 I change the exception to save to fmd.log, but that's if the compress method is faired. If it's not faired that's mean the download is incomplete.

Here's what shown

It seems there is some unsupported image type. I will check it later.

[ghost]

Sure, thanks.

Appreciate the help.

[riderkick]

I can't find Chihayafuru on MangaStre am?

[ghost]

Uh that's weird, FMD says MangaStream To

http://www.mangastream.to/chihaya-full.html

Seems that chapter 90 is jpg while the rest are png.

[riderkick]

Because there is Manga Stream.com

[ghost]

Ah yeah I see.

[riderkick]

It seems it's related to Imaging library. It doesn't work correctly with latest fpc. Very hard to trace, this library is big. I'm trying to look alternative library. For a moment just save it to cbz, there is many manga reader available.

[ghost]

Alright then, I'll save to cbz and then convert it to pdf through another program.

Thanks for the help!

[riderkick]

In 32bit it even make the main thread freeze. There is something wrong with the asm code, which is not compatible with latest fpc.

[ghost]

Hm I see, if it helps you in any way, this doesnt just happen with MangaStream.

[riderkick]

Of course, it's affected to all website. There is some special bits on image that make it unrecognized.

[riderkick]

Could you try to lower the compression level, 99 for example. It seems this error only occurred with lossless compression. I'll try to look at it again tomorrow.

[ghost]

99 is fine yeah.

I've been fixed all related issue to pdf compression with this commit https://github.com/riderkick/FMD/commit/1eedd6ddebad88f7009132143f55c807217df989, https://github.com/riderkick/FMD/commit/74cbb3afd9ee835a4e5760daf78998cf203782d5, https://github.com/riderkick/FMD/commit/ee6b68a4ed2f3c613dea4fd7ee9e7c3aae28a803

In lossless compression, I ignore jpeg images to be compressed to FlateDecode, because it's supported by default for pdf. So, it's better to use lossless compression, except if you use compression quality lower then decent quality (75-85). Larger compression quality will grow the size of images, probably larger than original size, usually original image using around 75-85.

Thanks!
