WebP Filetype (2022-08-14)

@Ferdari, you're asking others to do a lot of work on your behalf, and making assumptions about a lot of other people's decisions and motivations to fit your personal narrative and agenda. Chill out!

 

@Ego Eram Reputo's suggestion is the best one. If you truly are an "advanced user" as you claim to be, you'll figure out a solution. Maybe you fork the plugin, maybe you just find or write a little command-line utility to automate stripping out the metadata. Maybe you'll even come full circle and share your solution with us. Stop expecting everyone else to cater to your demands, and stop expecting everything to be super easy. That's not how you make progress, here or in life.

This plugin does not support creating or editing animated WebP images, it is designed for single frame images.

I will add a better error message in the next version.

The small increase in performance you get coding in C++ over C# is hardly enough to offset the headache of coding in the C++ language. ~BoltBait

Opening a webp A without an embedded exif chunk shows a dpi value of 120. I expected 72 dpi (the exif default value).

Setting the dpi value to 150, saving as B and opening B shows 150. So this works.

A and B show a dpi value of 72 in properties/details dialog of Windows Explorer. The difference is that B shows the ResolutionUnit. Looks like an explorer issue.

Release version 1.3.8.

Changes:

  • Updated to libwebp version 1.2.2.
  • Fixed a bug with the EXIF ColorSpace property handling.

I also added a note to the first post about animated images not being supported, and a link to the Animated WebP plugin.

More than 10 years of providing updates for this plugin. From the first WebP beta libraries to the now most stable version.

Thanks for that.
Let's see which image format will win the competition in the future. WebP, Avif, Jpeg XL, or maybe WebP2?

I suspect that all of those image formats will be competing against one another without a clear winner.

Hello,

I try to convert very large picture from PNG with alpha channel to WEBP .

 

This picture is really large, just near max resolution 16383x16383 but does not exceed maximum yet.

 

Paint net works with smaller pictures. This one stops at 52% and after a while throws exception. I have 20 GB free space on disc C.

 

The message:

I am sorry, actually Gimp throws same WebP error: 'partition is bigger than 512K'

 

Edit.

Okay, found the culprit:

-partition_limit int
Degrade quality by limiting the number of bits used by some macroblocks. Range is 0 (no degradation, the default) to 100 (full degradation). Useful values are usually around 30-70 for moderately large images. In the VP8 format, the so-called control partition has a limit of 512k and is used to store the following information: whether the macroblock is skipped, which segment it belongs to, whether it is coded as intra 4x4 or intra 16x16 mode, and finally the prediction modes to use for each of the sub-blocks. For a very large image, 512k only leaves room to few bits per 16x16 macroblock. The absolute minimum is 4 bits per macroblock. Skip, segment, and mode information can use up almost all these 4 bits (although the case is unlikely), which is problematic for very large images. The partition_limit factor controls how frequently the most bit-costly mode (intra 4x4) will be used. This is useful in case the 512k limit is reached and the following message is displayed: Error code: 6 (PARTITION0_OVERFLOW: Partition #0 is too big to fit 512k). If using -partition_limit is not enough to meet the 512k constraint, one should use less segments in order to save more header bits per macroblock. See the -segments option.
 
 
Is it possible to add more options to the Plugin? ;)

Those advanced encoding options are unlikely to be added, this plugin was never intended to expose all of the options that are available in Google's cwebp utility.

I recommend that you use cwebp if you need control over metadata or the other advanced WebP encoding options it provides.

Release version 1.3.13.

Changes:

  • Added a check box for lossless compression.
    • This replaces the previous behavior of silently using lossless compression when the quality is 100.
  • Improved metadata handling when loading files with the wrong extension.
  • Detect BMP files with the wrong extension.
