Re: Webp GUI - for Windows

[Paul A Norman]

Thanks Merlin,

My production environment complains "This application has failed to start because mingwin10.dll was not found. Re-installing the application may fix this problem."

Are there other .dlls that need to be bundled as well?

FWIW, there's quite some underlying library dependencies:

danke erstmal für die aufnahme des projekts
ist das ins programm eingebaut oder ist das eine GUI die auf das cwebp.exe zurückgreift
wenn ja fehlen mir da schon so einige einstellmöglichkeiten
drag & drop wäre übrigens nicht schlecht

i try english..
tnx for start this project
does the app include the webp-libs or does the app using commandline (cwebp.exe)
if yes - i missing some possible setups for this
btw drag & drop would be nice

hast du auch facebook account..?
wenn ja besuch uns mal bei der gruppe "WebP Alliance" https://www.facebook.com/groups/509583319099810/

[oX Triangle]

the idea for your app...

different editable setups switchable via click

maybe a parameterline with variables for input/output
variables contain imageresize helping calculator

in moment i have only some batchfiles under "send to" to convert complete directory

[oX Triangle]

@oX Triangle     I cant't promise that I'm able to add all of your ideas, but I'll do my best ;)

                          and what do you mean with a imageresize calculator? ( something to change the image size by 50% or something else ? )

yes - cwebp.exe only use absolute parameters for resize
as exs. if a user want fix the biggest side to 1920 cweb is unusable for batch convert

my biggest problem is to seperate horizontal and vertical alignment to different setups

exs.: what i mean is:

a) if both sides lower or same then 1920 -> no resize
b) if image be horizontal resize y to 1920 and calculate the x
c) if image be vertical resize x to 1920 and calculate the y

[Pascal Massimino]

Hi,

note that, in cwebp, if you specify a resize dimension of '0', it will be

replaced by the actual ratio-preserving value.

Eg., resizing a 960x1280 source using 'cwebp -resize 320 0 ...'

will produce a 320x427 output. And using 'cwebp -resize 0 320 ...'

will produce a 240x320 output.

I just realized that the 'man cwebp' doc is missing a description of

the '-resize' option (but there's one for '-crop'). Will fix that...

Is there a calculation you can do like a*b=c or so ?

(The man page for -crop isn't helping me at all :D )

 

-crop describes a rectangle whose upper left is (x,y) and lower right is (x+w,y+h)

-resize <width> <height> operates as expected when both width and height are specified.

When width is 0 (-resize 0 360): dst_width = src_width / src_height * dst_height -> 640 = 1280 / 720 * 360

When height is 0 (-resize 640 0): dst_height = src_height / src_width * dst_width -> 360 = 720 / 1280 * 640

which resample-methode cwebp use for resizing?
its comparable with lanczos or spline?

i uses box-averaging, since it's mainly designed for large *downscaling* (say, shrinking factor of at least 2x).

This method reduces high-frequency aliasing.

[oX Triangle]

if u search good algorithms for downscaling..

 i think the "Photivo" open source project should help

-m 5 and -m 6 generates files with large sizes than -m 4. why is so? is it a bug or a feature?

Are you using lossy or lossless compression?

For lossy, it can be that, for the same -q quality value, -m values give different sizes.

But this comes with lower distortion too.

So, basically, for a given -m value, the size will always decrease when -q decreases.

But comparing between -m values for a given -q is harder.

[JOZIKus]

Are you using lossy or lossless compression? ---> lossy

But this comes with lower distortion too. ---> can You explain this in a bit more detail?

But comparing between -m values for a given -q is harder. ---> I don't get the logic how superior compression -m 6 can result in larger file sizes than -m 4. are the image quality of -m 6 higher than -m 4 ? or is it both slower and generating larger file sizes for no logical reason?

For lossy compression, you must lose details to compress better. The -q parameter controls

how much you lose, and the -m controls how much time you spend trying to not lose too much

(by exploring lot of extra combinations).

See the following graph:

​For a given -m method, you're following one of the red curve when you change -q.

By changing -m, you globally switch to another "rail" which gives better quality

for similar size (but takes longer).

How it helps,

Wow this is so amazing.

Could I ask you if there is setting that can set outcome directory? Thanks. I can't find files anywhere.

[tuqueque tuquequin]

Excellent!

I'm using it on Linux though Wine and it works perfectly!... It may be even better if you could also offer it in native Linux form, but is still awesome... By far, the best WebP GUI batch converter in terms of flexibility/customizability available!

Please, keep it coming!

Can you add support for converting gifs to animated webp?

If cwebp.exe is able to do that, i could implement that.

anim2webp.exe is the specialized tool to do that.

 

But what is the point of animated webp?

There is a video version of .webp called .webm .

You could use that as a .gif alternative ( like 9gag.com already does on Chrome ).

The distinction between animation and movie is vague and people-dependent.

But animations are meant to be short (shorter than a .webm video file).

They consume less resources at decoding than a full-fledged video codec instantiation

(with all its frames buffer and such.) And they have no audio.

 

just fyi

Did you try the near lossless mode in the encoder?

This may be the last version of this GUI,

but I've created a universal GUI (called Argument Hopper) which can be used with almost every terminal/console software.

Argument Hopper is able to store the arguments in a profile (.ini file) and it should be able to do the same things as "Webp Converter GUI".

Get it here: http://merlinscheurer.de.tl/Software.htm

And thanks for the support to everyone who posted here and downloaded the GUI :)
