I would like to add text to an image using Images in julia.
I googled but results are not much helpful in this regard!
Please guide me adding text at specified co-ordintes to an image using Images in julia.
I am not aware of a solution using only Images, but you can do something like this with Plots and Images
using Plots, Images
img = load("test.png")
plot(img)
annotate!(1.,1.,text("test",20))

I want to make a pixelate image in moviepy, I have reference the following Doc:
Moviepy: https://zulko.github.io/moviepy/ref/videofx/moviepy.video.fx.all.resize.html
And tried the following:
clip = ImageClip("source.jpg").resize(0.01).resize(100)
While it does make the video blur, it does not produce a pixelated image.
What I want to do is something like the below:
Imagemagick: How to pixelate/blur an image using ImageMagick?
However, I want to prevent using imagemagick natively if possible. Would like to know if it is possible, thanks.
I have just downloaded the dataset caltech101 and I want to resize the image into the shape of (200,300,3). As I have read, I first need to convert the image into a tensor and then resize it using tf.image.decode_jpeg. But I don't know how to start from scratch with an image and turn it to a tensor.
(I'm a beginner in learning machine learning)
To load an image using TensorFlow, first decode it like so:
image = tf.image.decode_jpeg(...)
To resize it, use the image from the code above, like so:
resized_image = tf.image.resize_images(image, [299, 299])
You can find more on their API documents here.
I am using matplotlib to draw a graph using some data and I have saved it in Pdf format.Now I want to add a logo to this file.How can I do this.
Thanks in advance
If you can do it the other way round, it is easier:
plot the image
load the logo from file with, e.g. Image module (PIL)
add the logo with plt.imshow, use the extent keyword to place it correctly
save the image into PDF
(You may even want to plot the logo first, so that it stays in the background.)
Unfortunately, this does not work with vector graphics, but as logos usually are not that large, you may use a .png or even a .jpg.
If you already have the PDF's then this is not a matplotlib or python question. You need some PDF editing tools or libraries to add the logo. Possible, but an entirely different thing.
I have bulk of images (1000+); each image consists of several pictures as a result of scanning several pictures to single image (JPG)
I am looking for a Batch tool that will be able to automatically crop and save the images as separated files
Is it possible? Any such tool?
Thank you very much!
If the size of each crop and positions are the same, you can easily write processing steps using ImageMagick. Then, using some script language you can process whatever number of images you want.
I am using TCPDF to create PDF files converted from HTML input using it's writeHTML() function. However, images within the PDF have poor quality, while the original images have a high quality (as expected). The images are in PNG format. I already tried to use SetJPEGQuality(100), but that had no effect.
What is causing this?
Try using this:
$pdf->setImageScale(1.53);
http://sourceforge.net/projects/tcpdf/forums/forum/435311/topic/4831671
When using HTML to generate your PDFs you need to manually calculate the images dimensions by dividing it's original width and height by 1.53 and set the result as attributes.
For example, an image with dimensions of 200x100 pixels will become:
<img src="image.jpg" width="131" height="65" />
This is a nasty workaround and doesn't completely remove the blur, but the result is much better than without any scaling.
Try To convert your Image to JPG or JPEG first. Until Now, I DOnt have a problem to convert image with TCPDF. I Think TCPDF is powerfull, because it can convert arabic language too. I HAve try convert arabic font with fpdf n it still fail
Little Up.
I'd same quality problem and I solved it...
When you save your picture, do it in 8bits instead of 24bits and you will see a "beautiful anti-aliasing".
