QUESTION
I am working on a photo editing project and I am curious about why did my new photo lose it's brightness. The program shoud get 2 photos out of the original one. One of them shoud contain only RED value and the other shoud contain BLUE and GREEN values. But when I put them back together the brightness is not the same as in original picture.
Here is my code:
...ANSWER
Answered 2021-Jun-07 at 13:18blend2 = Image.blend(img, img2, 0.5)
The third argument, 0.5, is the alpha level of each layer. Essentially, you are setting each layer to be 50% transparent. This effectively reduces the brightness. Instead, you should read in img1 and img2 and then set the red layer of the second to the red layer of the first.
QUESTION
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:
...ANSWER
Answered 2021-Apr-02 at 12:39Ok, so I managed to find the issue. The problem was not with the resizing but with the label as @jasonharper had stated. The working way is very unclean and creates unused labels to store the variable to prevent movement to the python garbage. I have tried with an array/list however it doesn't seem to work, that code is below. I don't see many people having this issue in the future because it's so small but I'll put the working code below as well.
Code using list that doesn't work:
QUESTION
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:
Start with the background image.
Merge the foreground image with Color A filter applied, and also with an offset from the middle.
Merge the foreground image with Color B filter applied, in the middle.
Save the result in a file.
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?

QUESTION
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) :
...ANSWER
Answered 2020-Dec-06 at 20:33I just had to set the factor variable from ~1 to ~30 to change the contrast by giving these values to the function and the QSlider returned incorrect values.
It is also possible to reverse the image colors by passing values from -1 to -30, to also change the contrast of the reversed image.
so the right code will be like:
QUESTION
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

When I try to save, I get:
...ANSWER
Answered 2020-Mar-31 at 17:52Seems that you open the Image in Pillow and try to save the Pillow Image with OpenCV. OpenCV expect a numpy array. You should first convert your image before write in file with opencv.

I think, it will solve your issue
QUESTION
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:
...ANSWER
Answered 2020-Mar-14 at 20:56It seems unlikely you'd want to pass a PDF to OCR, since Tesseract et al prefer PNG or NetPBM PPM files, so you might as well split your big PDF into individual PNG (or other) files:
QUESTION
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/)
...ANSWER
Answered 2020-Jan-07 at 22:48Remember to add the FilePondPluginImageTransform, and FilePondPluginFileEncode, to your FilePond.registerPlugin when using imageEditEditor: Doka.create({}) in FilePond instance.
