JpegCrop Run on ReactOS?

Post by KenO »

Did a check of Applications and saw that IrfanView is working so hope that JpegCrop will also. Graphics * Pixel
o IrfanView (Licence: Closed Source) (Working)
o MrImage (Working)
o Tux Paint (Licence: GPL) (Working)
o GiMP (Gnu Image Manipulation Project) (licence: GPL)
o PhotoFiltre (image retouching program) (licence: Freeware)


Has anyone tried it?

Short Intro: I have tried every digital photo editor have been able to find and JpegCrop is the Best!!!

This is because it is Lossless and allows you to use Full Screen to change the Zoom from very small to 200% so you can view Exactly where your edit will actually occur. If you have Ever Been Disappointed with your JPEG Edits this is the one for you!

But dont take my word! Try it here! http://sylvana.net/jpegcrop/ Plus it is Free!

More info and download. The Jpegcrop Windows Application was initially developed to provide a convenient interactive user interface for the new jpegtran -crop feature.
It has now developed to a nearly complete user interface replacement for jpegtran, and furthermore for demonstration of the enhanced djpeg -scale feature.

jpegcrop.zip
Jpegcrop Windows Application (jpegcrop.exe and jpegcrop.txt), latest release 2004.06.

See also the Jpegcrop Preferences and Options description.
News (05-May-2003):
The most wanted feature currently for Jpegcrop is a "constrained aspect ratio" crop mode. If you need such a function to crop your photo images to the common 10x15 (3:2) photo frame, have a look at Stefan Scherer's Jpegcrop with FotoFrame feature. This is a preliminary Jpegcrop extension until an 'official' version will be available someday. Thanks to Stefan Scherer for this contribution! See also the lossless rotation apps page for more solutions (jpegtran Frontends "FotoView" from Martin Pola and "JPEGCrops" from Toke Eskildsen).

There is a German article and wish someone would translate it into English! http://www.photoworld2.de/photoworld/po ... -0,00.html


To me it is a Killer App for Reactos!

I checked to see if all my links work.

Unfortunately no.

the downloads do not.

Haos,

While you are correct "Its not being maintained. Last entry is from 2005."

The App is So Simple that there is nothing to maintain. It Just Works!

A number of people have added on to JpegCrop such as cPicture http://cpicture.net/en/ and a long list of other apps here http://sylvana.net/jpegcrop/losslessapps.html

But nothing can replace JpegCrop for doing what it was originally designed for. That is why I think it is a Must Have for ReactOS!

Hi,

I'm not sure if you understand the basics behind this program correctly. The program you describe is a simple program, which is only capable to open, view, rotate, flip, crop and save jpeg-images (and no other image formats).
Fortunately I can understand German and I am capable to understand the mathematics in the linked article. However, I think you did not understand that every major pixel-based imaging-software is able to do what your program does. The purpose of this program is to rotate, flip or crop FDC-transformed images without IDC-transforming (to load the image) and again FDC-transforming it (to save the image).
However, from a mathematical / physical point of view, this program is useless. The entropy of the image remains the same, as it can be saved again with a user-defined number of encoded coefficients, keeping the same entropy like the original image.
And again, from a artistic point of view, this program is also useless. You will never only open a image and only rotate, flip or crop it (these are the only operations where this mathematical "shortcut" can be taken). You will change contrast and lighting, hue and saturation etc. Even when only changing one pixel, this "shortcut" is not viable. Then you will need to retransform and encode the whole block / image.

Overall, in my opinion useless :?. But indeed a really nice research project and a nice mathematical approach :wink:

Cheers,
eXile.

eXile,

I normally shoot RAW and do all my corrections there. JPEGs are one of the final results. The most common one since they are much smaller than TIFFs

As previously stated it is JpegCrop ability to very the zoom from very small so I can see the entire photo to 200% so I can make sure the crop is exactly where I want it.

None of the other JPEG editors I have tried have allowed me to do this! Plus it is Lossless.

If you know of another editor that has these features I would be interested in testing it!

Wooha! I think every pixel editor in the world can zoom into images and still edit the selection (except Paint :().
None of the other JPEG editors I have tried have allowed me to do this!
What? Zoom in and edit the cropping region? You did test Photoshop, didn't you?!
Plus it is Lossless.
You do not understand the math behind it and you did not understand my last post.
If you know of another editor that has these features I would be interested in testing it!
Ok you tested The Gimp? Adobe Photoshop? Corel Paint Shop? The Gimp is free software, and Adobe got relatively cheap education versions.

Edit:
I have tried every digital photo editor have been able to find and JpegCrop is the Best!!!
If that was not a joke ... please ... think again.

eXile losses jpeg processing is kinda different.

It does not alter the data like gimp or photoshop. To be correct Haos has it right Irfranview does exactly the same with plugins http://www.irfanview.com/plugins.htm. 100 percent replacement with more features and power than the old jpegcrop.

Note jpegcrop alterations are done by http://www.ijg.org/ Open source code all it is a front end.

Most programs that do work like JpegCrop are called viewers. Not editors because they don't alter the data as such. They alter image scale and rotation to jpeg limits and size of image. That is it. They are not altering the image data. Say sorry eXile. Since you did not understand what the person was talking about. You don't use gimp or photoshop even for minor adjustments on jpegs due to the dataloss from both way conversion.

When it comes to that work I normally reach for http://perso.orange.fr/pierre.g/xnview/enfeatures.html . Mother of all viewer image tools. One place I do use closed source and pay for it.

Agreed with oiaohm, with no doubt.
Editors need to allow modification of a single pixel (RGB colour) on a given image, thus will require reencoding (if we speak about loosy compression). Editor will usually have quite a large amount of features, filters and tools.

Image viewers like Irfanview allow only simple operations - cropping, copy/paste, resize, rotate etc.

oiaohm,

Also missed XnView (v1.91.5/1.70) does it need any plugins (like IrfanView)?

Question?

Does XnView or JpegCrop run on Reactos?

Think the database may be out of date. http://www.reactos.org/support/index.ph ... cat/id/70/

Thanks

Ken
