![]() Sets a standard Windows color table for your image when you save an image with 1, 4 or 8 bits per pixel color resolution. HyperSnap selects the color table for your image that best matches all available colors on the original picture. Sets an optimized color palette when you save an image with 1, 4 or 8 bits per pixel color resolution. Select to save the image with 32 bits per pixel color resolution, which permits millions of colors in the image. Select to save the image with 24 bits per pixel color resolution, which permits millions of colors in the image. Select to save the image with 4 bits per pixel color resolution, which permits up to 65,536 colors in the image. Select to save the im age with 8 bits per pixel color resolution, which permits up to 256 colors in the image.

These may be black and white (if you select Std. ![]() Select to save the image with 1 bit per pixel color resolution, which permits only 2 colors in the image. You could reduce the image size to 8 bits per pixel without detectable image degradation. Ü Reduce file size if a high color depth is not needed for a good image.Įxample : An image may be set to 32 bits per pixel, but only needs to display 200 colors. Ü Set color depth to the lowest value available for the highest quality image. Select BestĬheck to have HyperSnap examine the image to try to: Keep CurrentĬheck this box to ensure that when you save a file, HyperSnap keeps the current image color depth (also called color resolution). These include whether the file is compressed and by what method, as well as other properties related to the file type you choose from the Save as type: drop-down menu. Select the sub-format properties for the desired file type. This is useful when the image must be uploaded to another application. Copy file path to clipboardĬheck this to copy the entire path plus file name of the current image to the clipboard. Save in:, File Name:, Save as type:, and the Save and Cancel buttons.Ĭheck this box if you want the HyperSnap window automatically minimized after you click Save. Tip: The most common Save as fields required by the average user are: The following text describes HyperSnap-specific fields and controls available in this dialog box. Dim poImage As Image = Image.FromFile("c:\myimage.jpg") Dim Original As Image = DirectCast(poImage.Clone(), Image) Dim OriginalSaveFileDateTime As DateTime OriginalSaveFileDateTime = FileDateTime(Image2Resize) If Original.Height > Original.Width Then ' Portrait Dim TempValue As Integer TempValue = poSizeWidth poSizeWidth = poSizeHeight poSizeHeight = TempValue End If gc.collect() Dim ResizedImage As Image = New Bitmap(poSizeWidth, poSizeHeight, Original.PixelFormat) Dim oGraphic As Graphics = Graphics.FromImage(ResizedImage) Dim oRectangle As Rectangle = New Rectangle(0, 0, 1024,768) oGraphic.CompositingQuality = .HighQuality oGraphic.SmoothingMode = .HighQuality oGraphic.InterpolationMode = .HighQualityBicubic oGraphic.DrawImage(Original, oRectangle) oGraphic.Dispose() Original.Dispose() ResizedImage.Save("c:\my-new-image.jpg", .Jpeg) ResizedImage.Dispose() poImage.Saves the current image to a graphics file, based on the format specifications and file name you provide in the Save as file dialog box that appears. ![]() if an exception happenned in between the file lock would stay until the garbage collector picked up the image which is non-deterministic thus you can end up with "funny" bugs where it fails the first time then fails the next 20 succeeding the 21st for no apparent reason. ![]() '3) Based upon #2 you need to be very careful about being sure to dispose of the image (i.e. You can use a FileStream and Image.FromStream() to get around the locking. ' Dim poImage As Image = Image.FromFile(Image2Resize) 'You could then make an overload that took the filename and passed the image to the main function (just a bit more generic in the long run) '2) Dim poImage As Image = Image.FromFile(Image2Resize) 'Its not too big of a deal here as you are disposing the object almost immediately after but I generally tell people to stay away from this method as it locks the file until disposed. '1) I would probably pass in the image as opposed to passing in the filename. My image is stored as an image my original jpg has the exif data (that is the 9 megapixel file) my saved jpg reduced for email is still a jpg but without the exif data this is my code which works fine but no exif ' Just a few comments on the code. ![]()
