            Label disappears when an Image is assigned to a PictureBox under it
            Asked 2020-Dec-16 at 04:11

            I've been through quite a number of posts about adding a Label over a PictureBox, and none of the ones I've seen explain why my label disappears when over a PictureBox.
            I created a completely new Label from scratch with the same problem, to rule out that perhaps I inadvertently changed some property without realizing it.

            When the Form first loads, the PictureBox has no initial image set.
            At this time, the Label is visible, but it's Paint event isn't called.

            When an Imaged is assigned to the PictureBox, through a Button click, the Label is no longer visible and the Paint event still isn't called.

            However, Paint events for another Label, outside of the PictureBox, are called.

            In the designer I see this:



            Answered 2020-Dec-16 at 00:41

            Relocate a Control to a different Parent container maintaining the relative position:

            Assume, as in the graphic sample, that the PictureBox.Location is (10, 100). In the Form Designer, a Label is positioned over the PictureBox, its Location is (20, 110).
            Its position, relative to the PictureBox.ClientRectangle, is then (10, 10) => (20-10, 110-100)).

            Of course, as shown, the Label's background color is inherited from its Parent, the Form (transparency of Controls is virtual, the Parent's background is used as the background of child Control that have a transparent BackColor).

            ► The PictureBox control is not a ContainerControl or a ScrollableControl (it doesn't implement IContainerControl; i.e., doesn't have the WS_EX_CONTROLPARENT style set), so it doesn't host a Control when you place one over its surface at design-time.

            At run-time, you can set a Control's Parent property to a PictureBox reference, to create a new Parent-Child relation between these two Controls.
            When you do, some properties related to a Control's layout need to be considered; in this case the Location property.
            Setting the Parent doesn't change the child Control's Location value, which is now relative to the new Parent.

            ► The Label.Location is still (20, 110), but now this position is related to the PictureBox.ClientRectangle, not the Form's. As a consequence, you have to relocate it, if you want it to keep its relative position.

            1. You can subtract the new Parent's Location from the child Control's Location:

            Why is the size of the TextBox cut off?
            Asked 2020-Oct-30 at 09:42

            I wrote a small control that allows to change from label to text box and vice versa, and everything is fine, the problem is that it cuts when going from label to text box, which is strange because while I was testing it everything worked perfectly.




            Answered 2020-Oct-30 at 09:42

            Setting this.AutoSize = false; in the constructor doesn't disable the property and the auto sizing remains. The type of the ToolBoxItem attribute of the Label control (as the CheckBox and the RadioButton) is AutoSizeToolboxItem which enables the AutoSize property when you drop an instance in the designer. This issue is well explained here.

            As the referred answer suggests, you can prevent this behavior by decorating the class with the [ToolboxItem(typeof(ToolboxItem))] attribute:



            dynamically focus on input (children component) using useRef doesn't work
            Asked 2020-Oct-13 at 08:44

            I have 'textRef' created in parent component and passed to children component using createRef(). I am trying to dynamically focus Input in children component on props change.

            It does work when I test on localhost (chrome) but not on web view.

            Any advice on this issue ? Thanks !!

            Answered 2020-Oct-12 at 08:55

            I resolved it by using input autoFocus attribute as well as ref attribute.

            Since input appears dynamically on a button click, ref.focus won't work.

            AutoFocus will get focus when the input appears.

            Then Ref will get re-focus where the input is already placed on address re-search.



            Changing Bounding Box Label Format
            Asked 2020-Aug-30 at 05:00

            I was looking for an online service that allow me to annotate images with bounding boxes, I found labelbox, but there bounding box label format is different than the format that I need which is yolo.

            This is there format: "bbox": { "top": 186, "left": 192, "height": 300, "width": 519 }.

            The format that i need is x_center y_center width height, also the values needs to be between 0 and 1

            x1 = bbox["left"]
            height = bbox["height"]
            width = bbox["width"]
            x2 = x1+width

            Augment labeled Data
            Asked 2020-Mar-24 at 16:07

            I'm trying to get familiar with modelling a CNN for an image detection project. Right now I'm stuck with preprocessing the image training data set:

            I have labeled 40 images with labelbox. Now I want to go on for image Data Augmentation. That is I want to rotate, flip etc. all labeled images in my data set to get more training datas to feed in my CNN. I want to do it with the "data_aug"-package from "" as it does Data Augmentation with labeled images (that is images with the boundary boxes). The problem is I don't know how to install this modul as the command pip or apt get doesn't run in the cell.

            Which command do I need? How can I install such a package? Or is there any much simpler way to do Data Augmentation with labeled images? Thanks in advance!



            Answered 2020-Mar-24 at 16:07

            I had a look around and it seems that "package" isn't so much a package, as it is a project with a Github repo available. So it isn't available via standard package builders; you'll have to manually download the data_aug guys' code. Luckily it's not hard.

            To start, just clone their repo:
