I am trying to save images in wpf application, but after saving some reddish tint color is coming on that images and also losing sharpness of those image. I am using PNGBitmapEncoder for that and saving imags in PNG format. I dont know what is happenning.
Anybody Plz give me the solution.. I am trying from so many days. Plz help me regarding this issue.
Thanks in advance
You'll need to post your code and possibly an example of what the incorrect image looks like.
The most likely explanation is that you've got a mis-match between the order of red green & blue pixels in memory vs what the file format is expected, or that the red value is being increased at the expense of the green & blue somehow.
Are you trying to resize the image as well? That might explain the blurriness.

In mobile view mapbox renders black image instead of raster image. I suspect this is because of the size of image(3.9 MB), also this is happening mostly on chrome browser for mobile. Please help me find the potential issue here?
This sounds as if you could be running into the No-Data issue, when rendering transparency.
The black background that appears is the part of the raster image that does not contain any data. Generally a raster image is a rectangular grid of pixels. When you are working with data that is not rectangular, there are pixels within the grid that don't contain any data. These pixels are expressed as NoData values and represent the absence of data. GeoTIFFs that are uploaded to Mapbox Studio are displayed as JPEG to save space and make maps load quickly. Since JPEG cannot display transparency, NoData values appear black.
Please see this documentation on how to resolve this:

First of I would like to thank the codename one team for the support to get me through some of the tough tasks I have faced. Now that I have solid app that I am ready to submit to the app store, I would like to know bit more detail or any examples of how the capturing photo can be cropped.
If I want to capture an photo using the camera, I want to crop it to desired width and height of the photo. Is there any example to crop the image and show the cropping area while taking picture?
Please advise.
Thank you.
Thanks!
You can use Image newImage = myImage.fill(desiredWidth, desiredHeight); this will retain aspect ratio and crop the redundant areas.
I exported a bunch of png files from R. The pictures are of a dataset that is 'spinning' against a white background. I then use GIMP to stitch them together and export an animated gif. Unfortunately, the gif has a yellowish color instead of a white background like the original files. This yellowish color was not there when I used to do this in imageMagick and isn't even there when I preview the files in GIMP. It only appears after I do the export as a gif. Does anybody know what is going on and how I can correct this?
GIF files are limited to 255 colors. If you don't downsacle colros prior to exporting them, GIMP will do that automatically at the export step itself. It is at this point that your yellowish background is being created.
The workaround is quite simple: convert your image to the indexed color model before exporting the GIF file (image->mode->indexed) ( perceive you could even force a custom crafted palette at this step). If after this conversion the backgroound is already yellowish, you can manually redefine it on the Color Map dialog (search for it on the Windows->Dockable menu) - pick the background color, and change it for white.
When exporting the Indexed image to an animated GIF there is no color conversion step, and the colors of the GIF are saved as they are seen on the screen
The issue here is GIMP is trying to do its best to convert your image down to 255 colors, and that is where it is failing. What I recommend for people on OSX is to get this program called ImageAlpha (it is free) https://pngmini.com/. It does a very good job and compressing png images without much loss. If anybody has a recommendation for a Windows app that would do this, please post it here for reference.
I am new to winforms and I want to keep things simple
When I create a message box: I notice the top half is white background while the lower half is grey (!!!)
(what I really want is all background white).
But even the VisualStudio dialog doesn't behave this way
Can someone please help me?
Do I need to write some custom code ?
I would post the image but not allowed;(
Thanks
MessageBoxes are displayed by the operating system. If the options that are available aren't good enough, then you have to make your own form.
