I'm in position to use a gif image inside a canvas but it doesn't changes it loads loads the first frame only and how to play the gif image completely or is there any way I could use gif formatted image inside a
canvas.
Quote from jsgif: A GIF player in JavaScript
Unfortunately, the DOM doesn't expose individual frames of a GIF, so
this is done by downloading the GIF (with XMLHttpRequest), parsing it,
and drawing it on a .
Maybe you would take a look in the jsgif source code to find some ideas

I am using Lazarus.
I have put 2 images on a form and synchronized their positions and sizes.
I can textout to both images, and after I made the ontop image transparent I can see the combined content of both images.
I can add further text to the bottom image and see it, but I can't see text I try to add to the transparent image.
I used the following code to make the top image transparent
image2.picture.Bitmap.TransparentColor:=clWhite;
image2.transparent:=true;
I guess I need to play with the image bitmap, but I can't find a solution that is not using other software.
Can someone help me with this please?
I need to take a picture with a frame effect.
Can I preview camera image with the transparent PNG and later save the image?
Thanks!
Use nativescript-camera-plus plugin to add preview within your app, style it around with your frame.
Once the picture is taken, use nativescript-bitmap-factory to create a new image that combines your frame and the actual image form camera.
I found this code on internet and everything works fine but I dont want to resize gif images because when I resize animated gif files, destroying animation. Or if it is easy to make resize animated gif images without losing animation ,,,
I am trying to save a png file in database using C#.
Bitmap thumbnail = new Bitmap(file.InputStream);
thumbnail = ImageUtilities.ResizeImage(thumbnail, Convert.ToInt32(width),Convert.ToInt32(height)); ImageUtilities.SaveJpeg(path,thumbnail,Convert.ToInt32(Resources.AppConstants.ExtractThumbnailQuality);
The image gets saved in database, but with a black background around the image. In short, it loses its transparency.
If I skip the resizing of image, instead of black background, a white background appears around the image.
Can anyone suggest, how to preserve the tranparency of the image
You are saving the resized image as JPEG. JPEG does not support transparency. Save it as PNG instead
So I have an image (GIF) with a blueish background and a circle (which i want to keep), I would like to remove the blueish background and ( or show the origin color of the back ground it sites on or make the background of the image totally transparent. )
Thank you .
This is GWT 1.6
GIF supports transparency also, open it in a image editor(not paint, it sucks) and select the background using the magic wand tool. Press delete and you're done!
PS: save it as GIF file if you have to..
This has nothing to do with GWT. The solution is to use PNG image format. PNGs allow you to specify a transparent background.
