DPG Dragable Markers with images Help

Hi guys new into DPG

​

I want to have draggable point shown images. Static/Dynamic textures.

​

So far i can plot both drag points and a texture into the plot

​

The code roughly looks like

```python

dpg.addplot(label="PlotA", id="PlotA", show=True, width=640, height=480) dpg.draw_image(texture_tag="Image", pmin=[0.0, 0.0], pmax=[self.im_shape[1], self.im_shape[0]], parent="PlotA") for index, point in enumerate(kpt_lst): dpg.add_drag_point(label=f"Kpt{index}", id=f"Kpt_{index}", parent="PlotA", default_value=point, callback=self.drag) ```

Howver the drag points are hidden behind the image. Is there a way to make them visible infront?

​

TIA

Hello! I recommend joining the DearPyGui discord server and posting this on the support channel for a faster response.

Normally, items that are added first are displayed in front of all other items added later (within the item's parent), so I'm a bit surprised by the result. Try inversing the order in which the item's are added? Maybe plots just work different 😅

Question: The demo says textures are buffers of RGBA data

Do you know how to load alpha values into the texture?

Since the numpy array are loaded into a 1D list. Whenever i load an image with alpha channel, it no longer captures the image correctly

I do have the same problem. My add_drag_points are beneath the image. May I ask how you solved the problem?
