cropper's Introduction

Cropper

Point and Shoot Screen Captures

Cropper is a screen capture utility written in C#. It makes it fast and easy to grab parts of your screen. Use it to easily crop out sections of vector graphic files such as Fireworks without having to flatten the files or open in a new editor. Use it to easily capture parts of a web site, including text and images. It's also great for writing documentation that needs images of your application or web site.

Default Hot Keys

Arrow keys: Nudge the main form one pixel.
Alt + Arrow keys: Resize the main form one pixel.
Alt + ] or Alt + [ : Resize the thumbnail indicator one pixel.
+Ctrl: Changes the amount of resizes and nudges listed above to ten pixels.
],[ or Mouse Wheel: Resize the main form twenty pixels while keeping the crosshairs centered.
Right Click: Context menu on the main form.
Double Click or Enter or S: Take a screen shot of the area under the Cropper window or start/stop a recording plug-in.
Tab: Cycle form colors.
Shift + LMB: Resize main form with 1:1 aspect ratio.
Ctrl + LMB: Resize main form relative to the center.
Ctrl + Shift + LMB: Resize main form relative to the center with 1:1 aspect ratio.
Shift + Tab: Cycle form sizes.
Ctrl + Shift + Tab: Cycle form sizes relative to the center.
Ctrl + Tab: Cycle thumbnail form sizes.
Esc: Hide the main form.
Ctrl + F8: Show the main form.

If Cropper is being used to save Print Screen images (Cropper will capture even while the crop form is minimized)

PrintScreen: Take a screen shot of the entire desktop or start/stop a recording plug-in.
Alt + PrintScreen: Take a screen shot of the current active window or start/stop a recording plug-in.
Ctrl + Alt + PrintScreen: Take a screen shot of the region below the mouse or start/stop a recording plug-in.

Output Options

Cropper is able to output images to a variety of formats. There is an extensibility model allowing developers to create custom output plug-ins. Descriptions of some of the default plug-ins are given below.

BMP: Large files but no compression artifacts.
PNG: Smaller files with lossless compression, good for most image formats except full color photographic. Think of it as a replacement for the simpler GIF format. All modern browsers can display a png file.
JPEG: Good for full color photographic images. Cropper can save jpg's in varying quality settings from 10 to 100. 10 being the lowest quality and smallest file size. 100 being the highest quality and largest file size. A quality setting of 60-70 is usually good for the web. It's a good trade off between file size and image quality.
Clipboard: The image is placed on the clipboard and can be pasted into any application that accepts images.
Printer: Presents a print dialog that allows you to send the image straight to the printer.

cropper's Issues

High DPI / scaling issues

Using Cropper on a Surface Book 2 currently set at 175% scaling.

A few issues related to high DPI seem to manifest:

The white labels of the crop size in pixels (top right corner) are overlapping the actual crop area and the bits that are overlapping will actually end up in the capture
Text scaling issues in the options window
Scaling issues with the How To and About "windows"

Keep up the good work, I absolutely love the tool!

App crashes on startup

Not sure if this due to a .NET framework compatibility issue or something. However, one day I started my computer and the application just stopped launching. This is likely due to some kind of software installed by my company (silently and without my knowledge, maybe a framework or something) which may have compatibility issues with the app. See screenshots and full stack trace below.

This is the latest version of the app available in releases (v1.11.0)
I have .NET versions 3.0, 3.5 and 4.7 (release 461814) installed

Steps to reproduce (on my machine only):

Run app
Icon appears in taskbar
Click taskbar icon 2 times
Error message displays with stack trace.

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

GIF-Plugin is gone?

There was a animated GIF output Plugin when this project was still hosted on codeplex (see https://cropperplugins.codeplex.com/). I can't find this plugin anywhere now.
Would it be possible to reintegrate the plugin in the distribution?

Support High DPI displays

Capture off center when using Scale and Layout increase

In windows 10, when using 125% or 150%, the center of the capture becomes more and more off as you increase. Just an annoyance, but changing back to 100% every time you want to capture is a pain. Any fix for this?

64-bit Version and Portable Version?

This app looks really interesting, please consider releasing a 64-bit and portable version 💃

When and why did "show" change into "show/hide"?

Previously (and it's still in the current front-page overview), F8 (which also turned into Ctrl-F8 but at least that's configurable) now also hides. Which sucks if you don't run Cropper "always on top": take screenshot, rename capture, then click back to browser I took the screenshot of, thus hiding cropper under browser… and then I need to hit Ctrl-F8 twice, once to actually hide the window, and then to show it again.

Cropper will not go beyond 1492 pixel width

When trying to scale Cropper to select a larger screen area, Cropper (1.11) will NOT go beyond 1492 pixels. This makes Cropper useless for larger captures.

Print with more than 1823 pixels wide

Hello,

For me, the print wide limit is 1823 pixels. It's possible do prints with more?

Thank you

Cropper no longer starts minimized.

Beginning with the latest version (1.11.0), cropper always starts up with the form displayed. I set this up to boot with Windows (and use it very frequently) so I don't need it to display on each login/reboot. I happened to notice this today after setting up a new computer and the blue form shows each time the application is launched. Version 1.10.0 is not affected, so I've downgraded to that.

Bug? Or, maybe feature request: Add the ability to configure this as an option (some people may actually prefer this). I'd suggest making the default value for this to be hidden on start up, carrying over for legacy reasons and, most likely, the most common use case 😄

Animated GIF

Future development : include cropping of video and save as animated gif or .mp4 including audio out.

Plugin links don't work

Can I get plugins for capturing animations anywhere?

Thanks.

Play a sound on screenshot?

Copied from CodePlex

Cropper is great, thanks. I'd like a feature where it plays a sound on successful screenshot. Just a little shutter click to confirm the image was made. Maybe as a plugin?

Cropper captures outside of the frame - capture is offset

Hello!

I am not sure why this is, but cropper captures outside of the frame.

Please see enclused image:

The capture actually includes the cropper frame!

The capture is the correct size, I checked, but it seems to be offset to the left and up.

Please let me know if there is anything I can try or add to this report.
Right now, cropper does not work for me, but I have always liked it and used it for many years.

BR! /marcus

Info on my setup:

Recent Dell latitude laptop, win10
Different docking / screen configs depending on office and workspace, during the day.
** Screen config does not seem to matter, as far as I can tell.
I have a custom scale factor set (see image below), but I have always had that for years, and cropper has worked for a long time with this set.

Don't paint main form area when taking screeshot instead of hiding form.

Will better support plugins that require the capture area to be hidden for a longer duration, i.e. the animated GIF plugin.
