Is it possible to play HTML5 video in reverse?
(6 answers)
Closed 10 days ago.
I want to reverse the video once it is played and play again in reverse.
I have tried using playbackrate as -1. But it is not working , the playback rate value -1 is not supported.
Playing a video in reverse is non-trivial in general, because many codecs rely on information from previous frames (when playing forward) to decode the current frame; when playing in reverse they'd need to seek around to find the required information.
You'd be better off making a version of the video that is a ping-pong loop by itself (i.e. one copy of the video in forward and one in reverse), and just loop that.

Convert SVG to PNG with applied images as background to svg elements
(1 answer)
Closed 1 year ago.
I am trying to convert an SVG to a PNG image. For this reason I use the npm package "dom-to-image". This and all other packages I tried (e.g. html2canvas) do not show a pattern/image in the polygon.
Here is a small example: https://stackblitz.com/edit/angular-ivy-h5e3aw?file=src/app/app.component.html
(External and internal Images produce the same result.)
How can I convert my complete SVG to a PNG?
Thank you very much.
Convert your image link to a data URL and it will work.
href="data:image/png;base64,iVBO ...snip... gg=="

program/library to read photoshop gradient .grd file

Photoshop export gradient ( .grd files )
(4 answers)
Closed 2 years ago.
I'm trying to generate .grd files in Javascript or PHP.
I googled a lot but I found that there is no way to do it yet!
I have gradient entries and I made it as PNG, CSS Code and SVG, And I want to convert one of these (or the original entries) into a .grd file that can let the visitors of the website download the gradient they want and then use it directly in Adobe Photoshop.
I found this library but it seems to not be for web. It's a Photoshop plugin programmed in JS.
After finding this library and it's made my JS that's mean it's possible to do it, and also it is going to be client side. That's cool.
It's not problem for me if it's server-side or client-side.
Any Idea please?
Thank you all

Android Canvas: drawing too large bitmap

Bitmap too large to be uploaded into a texture
(1 answer)
Closed 5 years ago.
I have an app that throws an error whenever I try to run the app on larger screen (With android studio emulator) It only does it on the screens with larger resolution though.
The background image that I am using in the app is set its size to twice the size of the screen, could this be the problem?
I have made it so the background rotates (for aesthetic purposes) I have set it to be twice the size of the screen as that is the only way I could figure out how to make it so that when the image rotates it does not leave parts of the screen without a background on it.
Whenever I try to run my app it throws this error:
FATAL EXCEPTION: main
Process: com.learn.earn.earnlearnapp, PID: 3039
java.lang.RuntimeException: Canvas: trying to draw too large(294000000bytes) bitmap.

Sorry, for my english. Thanks.
You'll need to (and I'm looking at the v2 API here) create your own edge shape, most likely based on mxConnector (in the shape folder). paintEdgeShape defines the rendering of the edge, you use the canvas API to define that drawing (see API specifications for mxAbstractCanvas2D).
