I create a binary input stream using some js trickery which contains compressed image data like jpeg or gif. I want to decode and display this data either using imgITools::decodeImageData or some other way but couldn't find a way yet. Where should I start?
The easiest way is to read the image data into a string, base64 encode the string, then turn that into a data: URL and set that as the src of your image. Unfortunately stackoverflow won't let me create a live data: link, but it would look like this:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABwAAAAcCAYAAAByDd+UAAAAMklEQVRIx2NgGAWjYBQMFXAFDRMrR5GF/6H4CglyoxaOWjhq4aiFg7hoGwWjYBTQDgAAy8VWOfRR6fkAAAAASUVORK5CYII="

I want to decode and understand the structure of various latest image formats (namely WebP, JPEG XL, HEIF and AVIF) and compare header information with respect to image data to see which format is header information heavy with respect to image data. I was wondering how I can do this using Python.
Is there a simple way to decode various image file formats of the same image in either HEX or Binary and learn how much of the file contents is the image data and how much else is the header information? Better yet, is there a way to learn the breakdown of header information for various file formats??
So far I got to a point where I got a file to open in binary mode (Below is the sample code I have for the AVIF test image) but I'm not sure how I can decrypt, read and understand the structure. Googling around, I found some information for JPEG format (like the information shown on this page for JPEG https://yasoob.me/posts/understanding-and-writing-jpeg-decoder-in-python/) but none for WebP, HEIF, and AVIF on how I can read the binary format.
image = 'test.avif'
with open(image, 'rb') as image_file:
content = image_file.read()
Content
I wish to know how exactly can we extract the header information from the images while compression.
I'm trying to convert pdf into image using gm package and i just can't understand how should i adjust the output resolution.
If i'm doing like this:
gm(`${sourcePath}[0]`)
.setFormat('jpg')
.stream()
.pipe(writeStream);
The output quality here is very low, so i'm trying to use density(594, 842)
like this:
gm(`${sourcePath}[0]`)
.setFormat('jpg')
.quality(100)
.density(595, 842)
.stream()
.pipe(writeStream);
but doing this the image looks very starchy.
Can anyone please point me what should i do in order to receive the
output image close as possible to the pdf source using the npm package?
Or maybe recommend me about a different library that i can use for converting pdf to image (before ocr)
I want to convert a piece of SVG to MVG. Could I do something similar to this convert msvg:pram.svg pram.mvg using RMagick methods? I don't want to save the output in a file, but I want to have it in a variable in Ruby.
In general, converting an image in one format to another format is as simple as making a copy of the image using a different suffix. https://rmagick.github.io/comtasks.html#convert
Use the to_blob method to get an image as a Ruby string:

I'm coding an API in ASP.NET that receives base64 encoded string to parse them into a DB. My problem is the following : these strings contain both an image and some text following it and I cannot find a way to separate them to then process he text part. Of course I have no possibility of changing the format.. So I was wondering if someone had an idea or a tool to detect the begining and end of the image and the text parts?
Here is a sample :

I cannot comment, so I post this as an answer:
You could decode the base64 encoded string to binary and try to detect the magic number of the image (assuming it has one). if it is an JPEG image it has a start and end signature. a BMP has the size of the image encoded into the header.
I have raw data from an email that contains a jpeg.
I can see the jpeg portion, but how do I take that data and create the jpeg so I can see the photo?
Raw data looks like this:
------=_NextPart_000_001F_01CF11D6.5A125C60

this is not the complete data, but this is what I see.
I need to take that data and turn it into a viewable photo.
Does anyone know how? can this be done?
I do not know exactly but according to this it says it is it is in Base 64, so try to just copy and paste the entirety of the code into a free online decoder like this one --> http://www.freeformatter.com/base64-encoder.html
This also also would send it back to you as a file which you should be able to save as a .jpg
Let me know if the full code works.
As per MSDN page Convert.FromBase64String Method in VB.Net, use:
Public Shared Function FromBase64String(s As String) As Byte()
for example:
Dim base64Encoded As String = "YmFzZTY0IGVuY29kZWQgc3RyaW5n"
Dim data() As Byte
data = System.Convert.FromBase64String(base64Encoded)
then save data to a file.
Example is from here
