QUESTION
I want to read, manipulate then save a png image while keeping its original info
properties mainly gamma
. I'm using Pillow
version 9.0.1
Code from SO mentions it can be done like this:
...ANSWER
Answered 2022-Mar-24 at 10:38Here is a way of doing what you ask, without using anything external. It inserts a gAMA chunk as follows:
- it gets PIL to encode the image into an "in-memory" PNG
- it opens the output file on disk in binary mode
- it then takes the 8-byte PNG signature created by PIL and writes it to disk
- likewise the 25-byte IHDR created by PIL
- then it creates a gAMA chunk with your value, prepends the length, appends a CRC and writes to disk
- then it copies the remainder of the PIL generated image to disk
Note: The PNG Specification stipulates that the signature must come first, then the IHDR chunk. It also stipulates that gAMA must come before IDAT, so there is no reason my code should create an invalid PNG unless:
PIL suddenly starts generating gAMA chunks, which would lead to multiple such chunks and would be illegal - but we are only doing this precisely because PIL does not write gAMA chunks, or
an unreasonable gamma value is provided, or
some aspect of writing to on-disk PNG fails due to disk full or other I/O error.
QUESTION
I saw, that Chromatic action is able to change the "details" link in PR check and post an additional comment. Can someone help me to set it up in my own workflow?check the image for example
...ANSWER
Answered 2022-Mar-23 at 14:05I believe they are coming from an external source and not GitHub Actions. If you are using GitHub Actions I do not think this is feasible.
You can however create a deployment environment and add the url
parameter to it so you can click the "View Deployment" button.
QUESTION
I did not find anything useful on the docs and on the web to solve this warning. I am using the library in Python only to load few png images, nothing more than load and show them on teh screen. Everything works perfectly apart this annoying warning:
libpng warning: cHRM: invalid chromaticities
This is the offending code:
p.s. CARDICON_1 ... _6 are png images.

QUESTION
I need to use a mono-chromatic camera API which states in its manual the following:
Each pixel (10, 11 or 12 bits) is coded on 16 bits. Pixel value is placed on the LSB of the 16 bits.
I will use WPF/C# with Bitmap; or I might use WPF with OpenGL. I don't have expertise in any.
Is the only way to down convert the pixels to 8-bit?(here someone mentions)
I came across the closest question here but with no answers.
...ANSWER
Answered 2022-Jan-21 at 14:45You may use a BitmapSource with Format
set to PixelFormats.Gray16
.
Then convert the source pixel values to 16-bit pixel values like this:

I currently have Gatsby installed on version 4, but I wanted to "downgrade" it to version 3, and all dependencies to be compatible with version 3.
Is there any method to "downgrade" everything to the most up-to-date V3 version?

I have create a map and I have to put some markers at some countries. I have already achieved putting some dots on the countries I want but I need some markers too. I have also tried this answer but I am having troubles with the coordinates and somehow the markers only appear on top left corner of the svg. Also I have seen some other posts as well but they didn't really worked, so pls don't close question and make it as a clone. Here's my snipped code:

Answered 2021-Oct-08 at 16:25The example you are attempting to copy is missing a right )
in the template literal. Even fixing that, though, your markers will be slightly off due to the image not being "centered" at the coordinates.

I am trying to make a very basic choropleth map with D3 that can be zoomed in and panned. Although this seems very trivial there are no correct example of this online. The example here has a non-bound panning and I find it quite cringe.
Here is what I have tried. I manage to get zoom factor updated, but the map does not change.

Answered 2021-Sep-21 at 22:39It sounds like setting the translateExtent on d3.zoom()

QUESTION
I'm fairly new to D3.js and I'm trying to make a wordcloud using Jason Davies' wordcloud library for D3. I'm not sure why the lesser frequent words overlap, and the distribution of words is such that there is a lot of empty spaces in between. I want it more condensed and structured. This is the
I have seen similar questions here and I've tried a lot of solutions mentioned earlier such as:
- Altering svg and canvas dimensions.
- Changing the font style like
.font('Helvetica')
- Using variations of 10 words, 30 words, and 50 words.
- Specified a text accessor function like this
.text(function(d) { return d.word; })
- Exploring options in
.padding()
- Used
.rotate(0)
Here is my code on JS Fiddle.
For the sizing of words, instead of the frequency
of occurrence of the word, I'm using rank
in my code. This is because the sizing gets disrupted due to the outliers in my dataset. Say the highest frequency is 32, and the lowest is 1, there is a large difference between the two sizes as they are proportionally mapped.
So I opted to size the words based on rank
. I have used Javascript to sort this data.
This is my first question here, so apologies if there is a lack of clarity. Would love any feedback or help/solution to this!
Thanks so much in advance :)
