There's not enough information on Internet about imagemagick and magick wand on Python 3. I need to create a lot of images using Python 3, creating the images with a background color or a background image.
When I get the image with the background I want, then I need to add text with a font of my preference on It, I think I can solve the problem of the font, but how to add the "string" in the image?
After that, I want to save the image with a "name".
I have installed Magick wand and Image Magick on Python 3, but the documentation is in a language that I really don't understand. Do I need to install something else?
If you're able to help me, it would be great. Thank you!
You can achieve these using Wand.
Creating the images with a background color or a background image
Add text with a font
Save the image with a “name”

I have an image and am trying to separate the background image and text.
For text I have used pytesseract and it gives me all the data. Now my aim is to translate this text and place it back on the image.
For that I need the background image and the position of the text where I need to put the text back.
I need some help or pointers as I have been trying to use OpenCV for same but no luck yet.
Thanks

I'm using GraphicsMagick for node.js and I'm trying to edit the attached image but unfortunately it adds a black contour and I don't know why. Maybe it it because I transform it from png to jpeg? Any help is much appreciated!
gm(image.file.path)
.quality(70)
.strip()
.samplingFactor(4, 2)
.interlace('JPEG')
.colorspace('sRGB');
I don't speak node but try something like this to set the background colour to yellow and then flatten the image with transparency over the top.
gm(image.file.path)
.quality(70)
.strip()
.background('yellow'),
.flatten()
.samplingFactor(4, 2)
.interlace('JPEG')
.colorspace('sRGB');
I have been working on PyTesseract OCR and converting PDF to JPEG inorder to OCR the image. A part of the image has a black background and white text, which Tesseract is unable to identify, whereas all other parts of my image are being read perfectly well. Is there a way to change a part of the image that has black background? I tried a few SO resources, but doesn't seem to help.
I am using Python 3, Open CV version 4 and PyTesseract
opencv has a bitwise not function wich correctly reverses the image
you can put a mask / freeze on the rest of the image (the part that is correct already) and use something like this:
imageWithMask = cv2.bitwise_not(imageWithMask)
alternatively you can also perform the operation on a copy of the image and only copy over parts / pixels / regions you need....
I'm working on a PHP script that automatically converts TIFF images to PNG files.
For that purpose, I use ImageMagick:
$ convert a.tif a.png
It works to some degree, however, the colours are very acute and deviant from the way they are pictured on my PC. To illustrate the problem, please have a look at the enclosed files, the include:
The Windows Live Foto Gallery output (that's pretty much how I want it to be)
The ImageMagick output (the mess I end up with)
The original TIFF file
Has anyone an idea whether, and if so how, I can alter the ImageMagick colour interpretation?
Thanks a lot!
Alright,
thanks to ergosys, the problem was easily solved: I needed to apply ICC colour profiles.
The XMP declared ISO 12647-2:2004, which was to be found at http://eci.org.
$ convert -profile ISOcoated_v2_eci.icc -profile eciRGB_v2.icc a.tif c.png
When converting from a CMYK color space to an RGB color space, as you do when going from tiff to png, you have to convert the color spaces along with the image. Try:
convert -colorspace rgb a.tif a.png
I ran this locally and get a better result from this than from the command line in your question, but my color vision sucks, so I can't guarantee that this is what you were after. =] Hope it gets you on the right track, anyway.
I have an image with Gray Background and 'CUP' in center of it... I want to detect the boundaries of the cup in this image.. After detecting CUP I want to extract the CUP from the image using IMAGEMAGICK.. Note I have many images with different objects (like CUP) in the center and with different background color .. So I am looking for a solution which is applicable to all of them..
Plz comment..
Maybe you could use edge-detection algorithms to isolate the shape of your main object: http://en.wikipedia.org/wiki/Edge_detection
You could also look into the code for the EdgeImage effect in ImageMagick, to see how they do it...
