You can use third party tools to generate icon files and bitmaps that contain an alpha channel. If you useLoadImageto load a 32 bpp bitmap that contains alpha, you need to specify the LR_CREATEDIBSECTION flag. Feedback Was this page helpful?
When you use a component as an item renderer, the data property contains the data to display. You can listen for this event and update the component when the data property changes. The FlexEvent.DATA_CHANGE constant defines the value of the type property of the event object for a dataChang...
If A contains indexed image data, you should additionally specify the map input argument. example imwrite(A,map,filename) writes the indexed image in A and its associated colormap map to the file specified by filename. If A is an indexed image of data type double or single, then imwrite...
If the encoded image is incomplete or contains an error, or if an Exception occurs during decoding, a DecodeException DecodeException will be thrown. In some cases, the ImageDecoder may have decoded part of the image. In order to display the partial image, an OnPartialImageListener OnPartialIma...
PNG images that contain grayscale or color data that has been sampled at a rate between 8 and 16 bits per sample may also contain an alpha channel(also called an alpha mask), which is an additional 8 to 16 bits (depending on the image color depth) that represents the transparency level...
Examining an Image varisMask:Bool Returns whether a bitmap image is an image mask. varwidth:Int Returns the width of a bitmap image, in pixels. varheight:Int Returns the height of a bitmap image. varbitsPerComponent:Int Returns the number of bits allocated for a single color component of...
Blur an image with a 2D kernel A box blur kernel returns the average value of the neighboring pixels. In the following example, the kernel contains nine values and the result is the sum of 1 divided by 9 multiplied by each of the pixel values: Note that the sum of the values in the...
The source code accompanying this article contains the sample application plus only a small subset of the Accord.NET Framework to avoid cluttering namespaces. If you wish to use Accord.NET, please be sure to download the latest version from the project page at GitHub. By the way, the sample...
The following code sample demonstrates most of the above mentioned features by interactively applying various transformations to an image. The file04_params.asp/aspxcontains a form with checkboxes and radio buttons controlling the visual appearance of the image. This file invokes the script04_process....
