3D_multiview_reg | Learning multiview 3D point cloud registration | Image Editing library

I am making an isometric game using python and the Tkinter library. I ran into a problem though when rendering my schematics to the screen. I can't seem to keep the transparent background even though the images (.png) are being stored as rgba in pil. When I save the images, as they are, just before being loaded; they still have a transparent background so it's something to do with the way I'm resizing the image. I have looked around and most answers to this that I have seen say to edit the pil plugin or aren't actually resizing the image. Is there a relatively simple way to resize an image and keep transparency that doesn't include messing around with the pil plugin??

My code:

I'm making achievements for my game, and I would like to make an automated process to save a lot of time instead of doing it manually. (I'm using Windows)

The inputs of this process would be

• one rectangular opaque background image (i.e. 200x200 PNG)

• Color A, (i.e. in hex)

• Color B, (i.e. in hex)

• and multiple same sized, rectangular, transparent foreground images. (i.e. 200x200 PNG)

And the process would do this for every foreground image:

1. Start with the background image.

2. Merge the foreground image with Color A filter applied, and also with an offset from the middle.

3. Merge the foreground image with Color B filter applied, in the middle.

4. Save the result in a file.

5. Apply a black & white filter and save the result in a file.

So the output would be for example multiple 200x200 PNG images, each of it having a colored and a black & white version

I think there must be an application capable of this.

But if not, is there a way to quickly do this in some programming/script language for example in Python?

I've used an example code (source: https://forum.qt.io/topic/11390/increasing-contrast-of-qimage/4) to change contrast of a QImage (I've also edited it a little) :

I am trying to make a large montage of 9 images in a grid of 3x3 on my windows 10 laptop. Image size of all 9 images are same. I did a research on Internet and found how to do it either vertically or horizontally but not for a array of images or grid. I downloaded ImageMagick software from their website to use their command line options as shown in this page but when I use the command given below, I get error montage is not recognized as an internal or external command, operable program or batch file

Please help or suggest another way to do it. Thanks

Here is the command I am using montage 1.jpg 2.jpg 3.jpg 4.jpg 5.jpg 6.jpg 7.jpg 8.jpg 9.jpg -geometry +3+3+3 montage_geom.jpg

I have an image opened with Image.open(). I make some changes, reassigning pixel RGV values,and try to save.

When I try to save, I get:

I have a multi-page PDF with photographed book pages. I want to remove gradients from every page to prepare for optical character recognition.

This command works fine on a PNG of a single page:

Is there any proper PHP code to use when cropping the image using the data that get passed from the hidden field when using the 'FilePondPluginFileEncode'? ( I'm using Doka as image editor) https://pqina.nl/doka/?ref=filepond

The below options get passed as encoded meta data from file-pond in a hidden field when I select an image and then edit crop. + the base64 image string ( https://pqina.nl/filepond/docs/patterns/plugins/file-encode/)
