This is very simple question and I am not able to get this information. Does driver.findElementByImage() work for svg image?

The image is downloaded from a slide captcha and I'm trying to find the gap in this image with OpenCV.
But the gap is missing in the image opened with cv2.imshow() .
I am not familiar with PNG nor OpenCV so I'm so confused right now.
I searched a lot but found nothing useful maybe caused by using wrong keywords.
image opened with Windows Viewer:
image opened with cv2.imshow() :
I'm wondering why the same image in image viewer and OpenCV looks different and is there an easy way to locate the difference?
I am having an issue where the images are rendered with a strange glowing effect around them, pictured here:
It is tough to see from this close but is extremely noticeable when viewing the app. Also, taking these screenshots into a design program and using the color dropper will prove that there is a glow around these images. Each of these images are PDF files, rendered as a template image so that I can change the tintColor instead of adding more images to my assets folder for each color.
I have read some other articles and questions that says there isn't full support for vector graphics yet (here). However, that is outdated as it specifies iOS 7 as the latest version at the time of writing. Now in iOS 13, I assume there have been changes. Another article I read said to never use vector graphics as they can get messed up when Xcode generates PNGs from the PDFs (here).
Information about the assets in my Images.xcassets:
Render as: Template Image
Resizing: Preserve Vector Data
Scales: Single Scale
I also tried to implement 3 PNGs at different sizes (#1x, #2x, #3x) for each image but got the same effect.
Creating new images with a smaller border size got rid of the glow but obviously, that doesn't fit the design style style that I want in an app. I designed these Icons in Sketch and used a border size of 3, then exported as PDF.
So, as I was writing this question I seemed to have found an answer.
It turns out it had nothing to do with anything in Xcode. The problem lies with Sketch. I redesigned each element in Adobe Illustrator, exported them as PDFs, set the same settings in the assets folder like so:
Render as: Template Image
Resizing: Preserve Vector Data
Scales: Single Scale
Here are the updated screenshots:
I am using:
Sketch (Version 52.5)
Adobe Illustrator (Version 24.2.1)
I don't know why this is an issue, but I hope it can help someone who has this issue down the road. If anyone has any more information on this, please write a comment :).
I am working on implementing a zoomable image viewer using OpenSeadragon and deep zoom images. I used the VIPS command line tool to create DZI files. My question is, does the original image used to create DZI files need to meet specific requirements to make it zoomable? (like format, size, etc.) If a normal .jpg image is converted to DZI, it seems like the image will not be zoomable. Is this correct?
My question is, does the original image used to create DZI files need to meet specific requirements to make it zoomable?
No, except to have a resolution higher than the screen resolution (in that case, the original image can be displayed directly).
I try to use svg file as some element's background image. When I save image as SVG 1.0/1.1 in Adobe Illustrator, it displays correct in my app. If I save image as SVG Tiny 1.1/1.1+/1.2 it doesn't displays in app.
I use next css:
background-image: url(img.svg);
Does iOS support SVG Tiny? Or what I must to do, that my SVG Tiny image will display in app as background image?
Yes, iOS and pretty much any browser/device that supports SVG also supports SVG Tiny. However, SVG Tiny is a subset of SVG intended for devices with poor performance, it will discard gradients, opacity, embedded fonts and filters. What is probably happening is that the features you are using in your file are being discarded by the Tiny format. SVG Tiny does nothing to save on file size.
In summary, just use SVG 1.1.
I wanted to know if anyone has ever used Tesseract with ImageMagick to get precise text from image. My main concern is with the small font texts present in an image (or some text that are not clearly visible). The only way I am able to retrieve those unclear texts are by modifying the image by ImageMagick like - by scaling the image, sometimes cropping the image....
I wanted to know if someone has integrated ImageMagick and Tesseract to create even powerful tool?
Till now, I have come up with a script that can search the text in the image... The script uses imagemagick and tesseract. The script is still under development, but you can look at it here
