ImageFormats

MaStaSk

I am using Qt 6.4 and Qt Creator 9.0.1 in Linux Mint and Windows 10 and cmake .
I need some further crossover Image handling. (TIFF support)

import QtQuick 2.12
import QtQuick.Window 2.12
//import QtImageFormats 1.0

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    color: "green"

    Image {
        id: imageView
        anchors.fill: parent
        //source: "file:///D:/Bilder/TEST_images/start.png"
        source: "file:///D:/Bilder/TEST_images/test.tif"
        fillMode: Image.PreserveAspectFit
    }
}

The Tiff image is shown when i run with msvc but not with mingw or gcc /g++ (on Linux)
I installed QtImageFormats with MaintenanceTool (on linux and windows) and tried to add it in the qml file and in the cmake file (find_package and set_target) but it doesnt work. When i activate line 3 in qml code ( //import QtImageFormats 1.0) i get error: "module "QtImageFormats" is not installed" but i found it in the QT plugins folder.

I can solve this issue in Windows using msvc but what can i do on the Linux System?

when i go back to version 5.15 it works on all platforms.
there is also an qtiff.dll in plugin folder of 5.15 but its not in 6.4.
i tried to find a libary but it seems there is no libary for the newer version?

Hi and welcome to devnet,

I would guess that is a package issue, unless explicitly disabled the plugin should be built and thus made available.

You should check the bug report system to see if there's already something related.
