I am changing a PNG image with a transparent background to HEIC format. I want to display the modified image using Android Studio's ImageView. To use the HEIC file I used an asset folder and an ImageDecoder.
However, the transparent background of the HEIC turned black.
I converted png to heic on various sites and exported it using mac preview app, but I couldn't stop the background from turning black. I would appreciate it if you solved.
here's my code:
<androidx.appcompat.widget.AppCompatImageView
android:layout_width="287dp"
android:layout_height="557.5dp"
android:layout_marginStart="1.8dp"
android:background="#android:color/transparent"
android:id="#+id/main_character"
android:layout_alignParentBottom="true"/>
val drawable1 = ImageDecoder.decodeDrawable(ImageDecoder.createSource(contextRepo.getValue("main").assets,"anna_character.heic"))
main_character.background = drawable1
I know fabricjs can play Video and sprite sheet, But I have a lot of gif files, can I play these gif directly with fabricjs? I am not able to find method in Fabricjs website.
According to specs about the Canvas 2DRenderingContext drawImage method,
Specifically, when a CanvasImageSource object represents an animated image in an
HTMLImageElement, the user agent must use the default image of the animation (the one
that the format defines is to be used when animation is not supported or is
disabled), or, if there is no such image, the first frame of the animation, when
rendering the image for CanvasRenderingContext2D APIs.
This means that only the first frame of our animated canvas will be drawn on the canvas.
This is because we don't have any control on animations inside an img tag.
And fabricjs is based on canvas API, thus regulated by the same rules.
The solution is you need to parse all the still-images from your animated gif and to export it as a sprite-sheet. You can then easily animate it in fabricjs thanks to the sprite class.
There's an svg image of Alabama's state flag # http://en.wikipedia.org/wiki/File:Flag_of_Alabama.svg
The caption says "This image rendered as PNG in other sizes." I downloaded the 1,000-pixel size #
http://upload.wikimedia.org/wikipedia/commons/thumb/5/5c/Flag_of_Alabama.svg/1000px-Flag_of_Alabama.svg.png but it won't display on my web page. I opened it in Photoshop, copied it into a new window and saved it with a new file name, but it still doesn't display.
So I guess I was wrong when I thought "rendered as a PNG" means an image is a png. It's actually a SVG...with a .png extension?
Anyway, I just wondered what's going on here and what I need to do to download such images as pngs. Or is the only solution to take a screenshot?
The PNG file you linked to (the ".png" link) is not an SVG. It is definitely a PNG.
I don't know why it isn't displaying for you, but it has nothing to do with SVG.
To get the image as .svg just copy the source of the page (of the image) to an editor. Now save it as an .svg image

Get the image in opencv Mat. Then use cvtColor function to convert the image. CV_BGR2GRAY code is used to convert from RGB to grayscale. Then show the grayscale image back to wherever you want to display it.
In a web page there is a gradient (in body tag) using CSS3. Moving next and adding image (logo with site name) I realized page gradient and image both has different colors. It is because web page has a background generated by CSS3 and image has a fixed color as background and both are different.
What I have tried ?
add image as background of a div and also as a img tag.
applying gradient on div
but no luck.
How it can be managed ? Please guide.
Thanks
Cant you just save the text of your logo as a .png with a transparent background? If you've added the gradient to your body tag it will change when the browser window expands and contracts
you have to save your logo image with transparent background....you open the psd file of the logo and disable the visibility of the background layer and then save it as a png image.
