I've used blender before, but it has been a while, and man has it gone through some changes. Anyways, to the point:
I am trying to upload a reference image so I may model around it, as to have an accurate model of my character. I've tried searching in Blender for the reference images I'll need, I've tried dragging and dropping it in, I've tried importing my image, nothing seems to be working.
Any ideas? I use Blender 2.82.
Just press Shift+A and select Image > Reference image or Image > Background Image
(Whichever suits you, I prefer the bkground image)

I'm working with fastai, trying to pass some images to a dataloader. The original images are kind of pinkish, but after passing them they appear mostly as green-black (see image in link below):
Original pinkish image (up) and example images (down) after passing them to dataloader, and the code.
The code I've used for the datablock and to show the images is:
example = DataBlock(
blocks=(ImageBlock, CategoryBlock),
get_items=get_image_files,
splitter=GrandparentSplitter(),
get_y=parent_label,
item_tfms=Resize(128)) #already tried it without item_tfms just in case, still black-green
dls = example.dataloaders(path)
dls.show_batch(nrows=1, ncols=3)
I tried with .tif and .jpeg images, and both show the same problem. The only thing that comes to my mind is that somewhat somewhere is not reading correctly the color format (RGB according to my original files), or maybe transforming it; but I'm not able to figure it out.
Just in case it's important, I'm working in a Jupyter notebook with a MackBook Air M1.
Thanks!

I am currently using Xamarin.Forms and I would like to import an image and be able to add markers to it. Similar to what the mapping apps do, but want to be able to do it from an uploaded image or from taking a photo. I would also Like to be able to set a scale on it after the image was uploaded by placing two or more markers and then entering a measurement between those markers.
When displaying an image/photo I would like to place markers on them that would have more info about the pinned location on the image. These pins must be saved in a database so that the next time it's opened the markers will be in the correct location as they were placed the first time.
If anyone knows how I can get started on this, or know of any libraries that allow you to this, it would really be appreciated.

Update
Loading the image from file, camera or url is simple enough.
Zooming in and out after the image is loaded was simple enough too. Altering the scale size of the Image by making use of the PinchGesture.
Moving the image around ended up being simple too, and it was achieved by using the PanGesture and altering the TranslationX and TranslationY.
.
.......Still searching for a working and reliable solution for adding Pins/Markers at a location on the image and the markers need to have a click or tap event attached to it.
I've Googled around a lot, and I checked the Unity Asset store but I cannot seem to find what I think is a common problem (or perhaps I'm doing it wrong).
The issue is when I use the Sprite Editor I cannot see a reference image which is useful for setting the sprite pivot.
When I open the Sprite Editor on a given image file, I cannot seem to add a background reference image:
I want to be able to see a background image (of a specific character for example) that I can position and then use that to set the pivot.
Do you know of any way to do this? Asset Store references are acceptable.
I found one for Animation pivot setting but not for static images.
Any and all suggestions welcome (if you have a workflow suggestion that mitigates this issue, feel free to suggest :) )
I found a free option that works well enough:

I am working on a Xamarin App compatible with all devices. I have a general question related to images. I am using Location Mark Image Icons to provide locations available on the Map. My issue is, Image has a white background which is also showing along with its background. I want to show only the Image.
Is this related to the designer to provide the image without background? Or as a developer, I can do something on it.
Xamarin.Forms doesn't delete your white background. What you need to do is following a small tutorial on how to use Adobe Photoshop for example and export your images as png, you might even consider which png type you need, there's 3 types of png:
png8
png24
png32
I won't be going deep in explaining each one of them, but you need to know that they all support transparency and could have a transparent background, however, you might notice some differences between them on the edges.
For example, png8 will give a small white border while png24 will not show that.
You can check this for example: https://helpx.adobe.com/photoshop-elements/using/optimizing-images-png-24-format.html
No, you can't do anything about it using Xamarin.Forms. You need to modify the image and remove the background (using Adobe Photoshop, etc.) and make sure to save it as .png.
If its simple white background you want to remove, You can utilise simple [MakeTransparent][1] method ofBitMap.
But this will remove all white coloured pixel. So IF your logo also contains white color, better you contact your designer.
Basically, I'd like to resize or resample a .png image (in order to reduce its file size) and yet retain it's transparency.
Anybody got an idea how best to go about this?
Thanks.
You can use paint.net, it is a free tool. Although it is pretty basic, it does the job.
Go to Image > Resize
Stumbled upon this thread and found the following site that does exactly what is requested: https://onlinepngtools.com/resize-png
What graphics program are you using?
Photoshop does this by simply going thru IMAGE > IMAGE SIZE and resizing. Transparency is not affected.
I'm sure Paint Shop Pro does the same
I know this is an old question, but the answer that worked for me was to use Inkscape.
Start Inkscape (free on Inkscape.org).
File -> Import... (Ctrl+I) the PNG file you want to resize (defaults on import dialog are ok).
With the image you just imported selected, select File -> Export PNG image... (Shift+Ctrl+E)
In the Export PNG Image tool pane, click the Export As... button to set the output filename and location.
In this same tool pane, set the image size using width/height or pixels.
In this same tool pane, click the Export button to create the output file.
This worked for me, hope it helps someone else.
Providing the image you have created / have been working on is transparent in the first place, using the "Resize" or "Resample" tools in any major image editing package (e.g. PhotoShop, PaintShop Pro and so on) should not affect (or lose) the transparency at all.
I use PaintShop Pro (X6, 64 Bit) myself and typically find that the "PNG Optimizer" option offers more options along these lines (than the default "Save As > .png" route).
Hope that this helps (specific to PaintShop Pro Users) in relation to the source question.
While I was waiting for the downloads of other image editing softwares, I tried Microsoft Power Point and succeeded in preserving the transparency.
Drag the image inside any slide, crop or resize, then save as a new picture as .png.
You can drag the image back in ppt to confirm the transparency is maintained
The complete Autodesk Sketchbook is now out for free including all the previous premium features such as resizing an image.
You do it as you would in paint by clicking on Image > Image Size... and then you can save as a .png without losing transparency.
Image size can be reduced by reducing number of colors and there are online tools to do this .
Try these..Hope they solve your problem

http://tools.dynamicdrive.com/imageoptimizer/ --It provides more output images with different number of colors. However, smoothness will be effected, take care.
