How to pixelate image in moviepy? - moviepy

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.

annotate!(1.,1.,text("test",20))

How do we load and resize image using tensorflow?

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])

imagemagick (or other) png->svg->png or svg->png

Im trying to convert either a svg to png or png to svg back to png with imagemagick and it seems like everything I try the final image is black outlined. I'm expecting it to keep all colors the same through-out the process but it doesn't seem to?
convert input.svg output.png
Even if I try the autotrace approach on the imagemagick site nothing changes. I'd prefer to just be able to have the input be PNG output to SVG (smooth borders) and then back out to PNG. Might sound silly but all of the smooth-bordering/anti-aliasing approaches mentioned on the imagemagick site seem to make all output (any colors but white) be black?

Merging a gif image with a png image

I'd like to merge this ordinary png file:
with this gif animation:
(source: mytree.co.il)
I don't want to use css' position and Z-index, it messes up my images which are located in table cells.
If you are looking to make gif image, try GIMP. Here are steps to make gif image with GIMP.

Good Luck.
Extract the gif frames with a software like http://www.addictivetips.com/windows-tips/how-to-extract-frames-from-gif-animation-image/
Use photoshop, GIMP or any similar image editor to merge the background to the images. Tools like magic wands with a precise threshold might help in the matter
Put it all together into a new gif file
Good luck

tcpdf: poor image quality

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".
