I've noticed that when using the Ctrl+C copy image to clipboard feature in qimgv, some things will accept it being pasted while others that should, won't. I end up having to use Honeyview to copy the image to clipboard instead, and then it works on everything I expect it to work on.

I've been wanting to wait until I had something more substantive than this, but I'm honestly not sure how I can compare the differences between qimgv's copy image to clipboard and Honeyview's. Do you know of any way to do this so I can describe this issue in greater detail? Or I suppose the alternative is you can try Honeyview and compare for yourself.

Installed qimgv using the official repo

use: qimgv /directory/with/movies

result: motage screen with movie previews (working)

use: qimgv /path/to/movie/file

result: message: [VideoPlayerInitProxy] Error - could not load player library Transparent video screen is visible

Compiled my own versions (used: "zypper source-install -D qimgv" to get the Suse patches". Applied only "qimgv-includepath.patch" and "qimgv-nosharedlib.patch") Was a bit toying around. The "createPlayerWidgetFn fn" seems also null?

It used to be that when toggling 1:1 and the image is bigger than the screen the image would be aligned/snapped to top, but latest patches changed it to middle, so top & bottom parts of the image are not visible without scrolling.

I'd prefer it to revert back as it's annoying to read comic pages like that, but I understand that might just be my preference, so lets add an option? :)

Opening a video file (mp4, webm) either directly or browsing a folder makes qimgv instantly crash.

Not sure what other information could be useful, playing videos in mpv works fine and glxgears (OpenGL) works just fine.

I keep getting this error when I click on the picture when viewing it:

The procedure entry point ?left@QString@@QEBA?AVI@H@Z could not be located in the dynamic link library Qt5Core.dll.

The file is available in the directory where the program is located. I'm running the portable version.

When will the installer format release be available? 7z format is also not convenient, since not all users have enough knowledge to open it, it is better to zip.

I ask you, please collect the installer, it's not difficult, programs like Inno Setup can do this without much difficulty.

The program has been added to my website with approximately 1300 people daily traffic (link).

Windows 10 0.8.6 x64

When I directly open attached image, Qimgv window opens but shows nothing. When I switch to webp from another image, it shows successfully.

mbike.webp.zip zip because github doesn't supports webp upload

In my system with qimgv (git-master) loading the next or previous image in a folder loads a picture that doesn't follow the current one. For example, if the current picture is the 5th out of 10, it may not load the 4th or the 6th.

System information: Debian Bullseye (testing) qimgv: git-master

qimgv-non-sequential.zip

Hi,

I'm running the very latest qimgv that I just compiled and have verified that these two issues are present.

1. When viewing mp4/webm clips, the seekbar immediately disappears and doesn't show up on hover/mouse move. This used to work in all versions prior to 0.9.0

2. I've noticed that you cannot move/copy files that contain''#' in the name. Error message says Source file does not exist. To verify, rename any file to test #test.jpg for example and attempt to move it. Also, you cannot rename such files either (empty file rename message box shows up).

Thanks!

Generally speaking, most apps will have the context menu spawn going upward rather than downward if the cursor is too far down, leftward instead of rightward if the cursor is too far to the right, or both if both are true.

to be honest i'm not sure if it's something to report. RMB hold and move up/down is great way to control zoom of images, but it collides with plasma gestures (if also set to RMB) — making it impossible to use. i know there are plenty of options which include excluding gestures for specific applications, yet i decided to inform You (@easymodo) that this takes place, and perhaps it's wise in this situation to let user control which button to hold for zoom, just as other keys are controllable. thanks!

There is currently no way to have directory-specific sort settings, i.e. the default sort settings applies to all directories. Implementing this would be nice, but maybe a simpler approach would be to expose sorting as a command line argument. That way a user can have default sorting (e.g. for me A-Z makes the most sense in general because files are usually named with timestamps and probably viewed in order from oldest to newest), while for phone pictures we tend to view photos from newest to oldest created/modified. In this example, A-Z can be set as the default and a simple wrapper command to use qimgv with sorting set to newest to oldest created/modified via command line for ~/pictures/phone is a suitable approach.

This is useful for viewing files in a directory as a one-off; however, directory-specific settings are still more useful if you're using qimgv to navigate and view files from multiple directories, in which case the problem of the same sort setting applying to all directories still exists.

I don't believe there's a specific feature request for directory-specific sort settings, but if there isn't, feel free to change the title to that as that is the preferred approach.

run the program first and then load the image file, there is no problem.

However, when I double-click the image file to run it, the image and window size are slightly larger.

If it's a small picture, it doesn't matter much. However, the big picture where the "screen area limit option" is applied is clearly visible.

on windows 11, 10 Automated build version,

If the next/previous image I'm changing to has the same dimensions as the current one, it would be nice to be able to preserve the zoom level and pan position. The viewport can switch back to default zoom/fit when the resolution of the image I'm changing to differs from the current one.

Use case: This would be handy if you want to compare two similar images, for example, say noise levels

This could be a toggle in the settings.

Hi I use qimgv 1.0.2-2 on Arch Linux.

I opened an image located in a folder with several images, I was going to the next images by pressing the right arrow, qimgv crashed at some point.

Here is the backtrace generated with gdb:

I'm running Ubuntu 22.04.1 LTS. When following the build instructions, my output is

-- The CXX compiler identification is GNU 11.3.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/c++ - skipped
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Build configuration: 
-- Qt Version: 5.15.3
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.2") 
-- Checking for module 'exiv2'
--   Found exiv2, version 0.27.5
-- Found OpenCV: /usr (found version "4.5.4") found components: core imgproc 
-- Could NOT find Qt5LinguistTools (missing: Qt5LinguistTools_DIR)
CMake Warning at qimgv/CMakeLists.txt:11 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake

  but it set Qt5_FOUND to FALSE so package "Qt5" is considered to be NOT
  FOUND.  Reason given by package:

  Failed to find Qt5 component "LinguistTools" config file at
  "/usr/lib/x86_64-linux-gnu/cmake/Qt5LinguistTools/Qt5LinguistToolsConfig.cmake"


  



CMake Error at qimgv/CMakeLists.txt:29 (qt5_add_translation):
  Unknown CMake command "qt5_add_translation".


-- Configuring incomplete, errors occurred!

In addition to the packages listed to build, I also needed qttools5-dev.

Once that is installed, the build completes successfully. All that's needed is a wiki update.
