I done the following:
I made a screenshot of my linux desktop with gnome-screenshot then converted it to a bmp image and dumped it as raw hex values with xxd -ps.[resolution:969x1920]
From the bmp image i made before, i cropped a small area and exported it to another bmp image and dumped it as raw hex values as well with same method as before.[resolution:47x79]
Now when i go and copy a row of hex values (lets say from the end of the file just to avoid any headers) from the smaller image and try to find it on the other dumped file, it shows that there is not there.
I don't know much from image formats, i just want to know if there is something fundamental behind it that i am missing and i have to study before trying again something similar.
Thank you in advance!
I made an svg animation using inkscape and Shapeshifter.design. Each number here is its own path. It looks good but the resulting output is 3.5mb!! I've tried svg reduction websites but no luck. Is there a way to implement this that isn't so big? Raw svg is too big to upload here so i am adding a link to a file
I want to convert image files into .svg format.
I used bunch of tools out there but they gave us with this format
<svg ... >
<image
xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAT
....
But I want to have svg file with path attributes.
Any recommendation would be great help.
Not really a programming question, but a quick answer is inkscape, the has a function called 'Trace Bitmap' to turn a raster image such as the png you mention into paths.
Is there a way to ungroup objects of a saved powerpoint jpg file ?
like a rectangular shape over a text made using powerpoint and saved image as jpg , is there a way to separate rectangular shape and review the text ?
A jpg file is flat. It doesn't care if it was a face photo or a converted powerpoint; the information you want is not present in the file any more.
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".
