image-viewer | A simple image viewer with some editing functionality | Dektop Application library

I’ve been trying to build a simple svg editor to try out svelte. Its been going great until I built a select box for the element to drag along with the active selected element. While dragging that selected element the selection box lags behind the element itself. I’m not sure whats wrong.

I’ve tried a few things like using the store to pass location data and putting events on a parent element so everything calculates on the same component in case that might be the issue but still it doesn’t work. I’m not sure what I’m doing wrong. I’ve been trying to figure this out for a while but don’t have any idea what might be the issue.

You can check my codesandbox simplified demo of it here: codesandbox.io

I'm coding a super basic canvas-based image viewer. I'm trying to implement image panning. I want to be able to hold my mouse button down and move the mouse to pan the image around. I'm using the mouse up and down events to enter and leave a "panning mode". My mouse move handler never seems to see that the panning boolean changes from false to true, though.

I've tried writing my functions as arrow functions instead, thinking maybe it was something to do with the fact that these are DOM handlers (issues with this or something), but that didn't seem to make any difference.

I have a heads-up display that shows the panning state and it updates accordingly, but my console logs within the mouse move handler always show the variable as false.

How can I get this panning boolean value to update as you'd expect within my mouse move handler?

Here is my trimmed down code, which is testable in my codepen link further down ...

I'm making an Android game. I want to make it move like the picture. I think I need a different method than the method of moving to the touch position or the method such as the joystick, but I can't feel it. Any help would be appreciated.

This is my product image viewer component.html. In this component the template reference variable #divZoomed is used to display the zoom.

I am trying to implement something like google arts and culture image zoom and pan.

Look here for example.

I tried working with ng2-image-viewer library but can't seem to be able to work it out.

Following is the snippet i tried.

I have used the code posted here by SebasianKruse https://forums.xamarin.com/discussion/74168/full-screen-image-viewer-with-pinch-to-zoom-pan-to-move-tap-to-show-captions-for-xamarin-forms/p2 to be able to pinch zoom and pan my image. It works great in Android, but in IOS I can't zoom nor pan.

I tried to set a breakpoint inside the OnPanUpdated but its never reached on IOS.

here is my code:

It has been more than a week, i have tried almost all option on Kofax Total Agility 7.6 "Transformation Designer"

I have a requirement of:

• Locating and Extracting the table content of a document(English or French)

To be able to do that i follow steps:

1. Open "Transformation Designer"
2. Created an extraction project, attached a sample document (having 5 pages)
3. Navigate to project settings->Table tab
4. Trying to create new "table header pack"

Note: All training material covers only single page document where extraction is quite straight forward

Any help?

Recently, I am trying to use PyQT5 to make a PDF viewer. I adapted the code provided in this post (Image Viewer GUI fails to properly map coordinates for mouse press event). I created a QScrollArea that contains a QVBoxLayout in order to dynamically add multiple QLables into the scroll area. Then I will load the PDF pages as QImage (pixmap) into each individual QLabel. I have successfully loaded and display the PDF pages in the QLabels. However, I encountered a problem. The QLabel in the vertical layout with the PDF page images cannot expand to show the whole page (according to the size of QImage pixmap). So the outcome of using this way will be only showing a small part of page. I cannot scroll down all the page as well. I expected that the PDF pages can be loaded into QLabels and well expanded according to the contents. Then, the Qlabels can vertically grouped in the layout. The layout can auto expand and resize according to the QLable. Finally, I can scroll down the scrollArea to read all the PDF pages. Just like other PDF reader does.

Additionally, how can I capture the mouse position in each QLabel? Ultimately, I want to let the user to click on the specific location on the page to add the text on that position. After I got the coordinates from the QLabel and specific page number, I will pass the information to PyMuPDF to write the text to textBox and export a PDF file.

Here is my code so far:

I've created a simple radio button group per the BS4 documentation example, but whenever I select a button, I can't help but notice that the active button border juts out a bit on the right side. From what I can tell, it seems like it's trying to make room for "extra" blank space to the right of the button's input text.

This same "jutting out" to the right occurs on all buttons selected within the group, not just the center button.
