image-scaling

Im looking for a way to use bitmap as input to Glide. I am even not sure if its possible. It's for resizing purposes. Glide has a good image enhancement with scale. The problem is that I have resources as bitmap already loaded to memory. The only solution I could find is to store images to temporary file and reload them back to Glide as inputStream/file.. Is there a better way to achieve that ? Please before answering .. Im not talking about output from Glide.. .asBitmap().get() I know that.I need help with input. Here is my workaround solution: Bitmap bitmapNew=null; try { // ContextWrapper

Often asked, never answered (at least not in a reproducible way). I have an image view with an image that is smaller than the view. I want to scale the image to the width of the screen and adjust the height of the ImageView to reflect the proportionally correct height of the image. <ImageView android:layout_width="fill_parent" android:layout_height="wrap_content" /> This results in the image centered at its original size (smaller then the screen width) with margins at the side. No good. So I added android:adjustViewBounds="true" Same effect, no good. I added android:scaleType="centerInside"

Changing the size of an Image Widget in GWT changes the size of the image element, but does not rescale the image on the screen. Therefore, the following will not work: Image image = new Image(myImageResource); image.setHeight(newHeight); image.setWidth(newWidth); image.setPixelSize(newWidth, newHeight); This is because GWT implements its Image widget by setting the background-image of the HTML <img... /> element as the image, using CSS. How does one get the actual image to resize? Daniel I saw this blog entry , which solves the problem by using a GWT DataResource instead of ImageResource. It

I'm trying to implement image scaling in OpenGL using only glTexCoord2f() and glVertex2f() . Let me explain: after loading a QImage and sending it to the gpu with glTexImage2D() I have to perform image scaling operations based on Qt's specification . Qt defines these 3 operations (see image below): I think this is the only way to do it since my application is a Qt plugin and this task needs to be done inside the paint() method of the class. The IgnoreAspectRatio operation is pretty straight forward and it's working right now. The KeepAspectRatio gave me some trouble initially but now it's also

I wanted to know if we can resize an image. Suppose if we want to draw an image of 200x200 actual size with a size of 100 x 100 size on our blackberry screen. Thanks Maksym Gontar Just an alternative: BlackBerry - draw image on the screen BlackBerry - image 3D transform You can do this pretty simply using the EncodedImage.scaleImage32() method. You'll need to provide it with the factors by which you want to scale the width and height (as a Fixed32 ). Here's some sample code which determines the scale factor for the width and height by dividing the original image size by the desired size, using

What is the best way to scale a 2D image array? For instance, suppose I have an image of 1024 x 2048 bytes, with each byte being a pixel. Each pixel is a grayscale level from 0 to 255. I would like to be able to scale this image by an arbitrary factor and get a new image. So, if I scale the image by a factor of 0.68, I should get a new image of size 0.68*1024 x 0.68*2048. some pixels will be collapsed onto each other. And, if I scale by a factor of say 3.15, I would get a larger image with pixels being duplicated. So, what's the best way to accomplish this? Next, I would like to be able to
