tiff

I need to open all frames from Tiff image in WPF into memory and then delete the source. And after that I eventually need to render that image (resized according to window size). My solution is quite slow and I cannot delete file source before the first require. Any best practices? Ray Burns Use CacheOption = BitmapCacheOption.OnLoad This option can be used with the BitmapImage.CacheOption property or as an argument to BitmapDecoder.Create() If you want to access multiple frames once the images is loaded you'll have to use BitmapDecoder.Create . In either case the file will be loaded fully and

I was only able to find one previous post regarding this, and the provided answer did not seem to work correctly. Is there ANY way to show a TIFF image with pinch / zoom ability in Android? Writing an app and I need to show a TIFF image. There appears to be, in fact, a way to display a TIFF image on Android even though that format isn't supported by ImageView. Take a look at this project . If you want to show tiff images in your android app but don't want to build native components, look there https://github.com/Beyka/Android-TiffBitmapFactory Is my library for working with tiff. 来源： https:/

I don't understand really well the premultiplied alpha. I need a NSBitmapImageRep without alpha channel (I don't need a particular bpp). My problem is that this code give me errors: NSSize imageSize = NSMakeSize(200, 200); //create a non-alpha RGB image rep with the same dimensions as the image NSBitmapImageRep* bitmap = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:imageSize.width pixelsHigh:imageSize.height bitsPerSample:8 samplesPerPixel:3 hasAlpha:NO isPlanar:NO bitmapFormat:NSAlphaNonpremultipliedBitmapFormat bytesPerRow:(3 * imageSize.width) bitsPerPixel:24]; //lock

I am trying to create a TIFF image from a UIImage . I looked into Apple's docs but could not find any information. Can anyone help me and explain how to create a TIFF image on an iPad? It seems to me that ImageMagick is way overkill just to write tiffs. Why not build libtiff ? iOS is supported from it, and is what most software packages use to write tiffs (including ImageMagick). You can even use the libtiff.a file from the ImageMagick link above. Just install the lib and tiff headers into your project. EDIT: Here is a nice tutorial showing you how to write a tiff once you have installed

I'm interesting in creating a layered tif with Java in a way that Photoshop will recognize the layers. I was able to create a multi-page tif , but Photoshop does not recognize the pages as layers. The pages are viewable with Acrobat though. Anyone know how Photoshop stores tif layer data and how that could be generated with Java? Thanks. I have researched this for my TIFF ImageIO plugin , and as far as I understand, the way Photoshop stores layer information in TIFFs is completely proprietary and not using standard TIFF mechanisms, like multi-page documents utilizing linked or nested IFDs (
