Bluestacks 4 Download 64 Bits [UPD]
Jacalyn Loston
I recently downloaded Bluestacks on my PC to play Brawl Stars. The thing is that it says that I need an Android Pie 64-bits instance. I read the article that Bluestacks redirects me to, but it says this when I try creating it:
I am newbie in regards with bluestacks... I downloaded it and was given the incompatible windows setting prompt, so I did the instructions it gave me to enable THESE, except the Hyper-V as it wasn't showing on Windows Feature List.
I've tried countless emulators in the past (LD, bluestacks 32, bluestacks 5, Mumu, Memu, Nox) and bluestacks 64bit is by far the best one at least for me in terms of performance. There's still some slight lag on selecting/promoting units but other than that, everything is really smooth including S3's.
I'm a budding hobbyist photographer and I'm trying to use Bluestacks (for Window 10 64-bit--- -bluestacks.html) on Windows 10 to run the Merlin Bird ID app. I have successfully downloaded the Bluestacks 5-beta and the Merlin app apk ( -bird-id-by-cornell-lab) for Windows. However, although Merlin icon shows up on Bluestacks, when selecting it, all that appears is Bluestacks framing an essentially white, blank screen. I have the feeling that this is because my computer (HP750-114, i5 core) has its virtualization function disabled. To enable virtualization, I will have to enter the computer's BIOS ( -us/articles/115003174386#%E2%80%9C10%E2%80%9D). I gave it a try, but when it came to having to select F7 (from my keyboard), nothing happened. Having very, very little experience with BIOS, I then opted to continue to re-boot...simply chicken out. The computer re-booted successfully, but I didn't get to enabling virtualization. Obviously, my lack of experience lead to a lack of confidence. Just couldn't continue as the presenting screens didn't jive with the tutorial. Not sure where I went wrong and would surely appreciate some help in getting Bluestacks to function with Merlin. Attached are images of the open Bluestacks with the Merlin icon, followed by the opened but blank Merlin. BTW, I might add that when selecting the Merlin icon, one does fleetingly see Merlin's opening screen, but it's gone in a flash. Thanks.
ImageJ converts 16-bit and 32-bit images and stacks to 8-bits by linearly scaling from min-max to 0-255, where min and max are the two values displayed in the Image>Adjust>Brightness>Contrast tool. Image>Show Info displays these two values as the "Display range". Note that this scaling is not done if "Scale When Converting" is not checked in Edit>Options>Conversions. RGB images are converted to grayscale using the formula gray=(red+green+blue)/3 orgray=0.299red+0.587green+0.114blue if "Weighted RGB to Grayscale Conversion" is checked in Edit>Options>Conversions.16-bitConverts to unsigned 16-bit grayscale. Theactive image must be 8-bit grayscale or 32-bit grayscale.32-bitConverts to signed 32-bit floating-pointgrayscale. The active image must be 8-bit grayscale or 16-bit grayscale.8-bit ColorConverts to 8-bit indexed color usingHeckbert's median-cut color quantization algorithm. A dialog box allows the number of colors (2-256) to be specified.The active image must be RGB color.RGB ColorConverts to 32-bit RGB color. The activeimage must be grayscale, 8-bit Color, or an RGB (red, green, blue) or HSB (hue, saturation and brightness) stack.RGB StackConverts to a 3-slice (red, green, blue)stack. The active image must be RGB color.HSB StackConverts to a 3-slice (hue, saturation andbrightness) stack. The active image must be RGB color.An attempt to perform an unsupported conversion causes a dialog box to be displayed that lists the possible conversions.The * indicates that both single images and stacks can be converted.Adjust SubmenuThis submenu contains commands thatadjust brightness/contrast, threshold levels and image size.Brightness/Contrast...Use this tool to interactively alter the brightness and contrast of the active image. With 8-bit images, brightness and contrast are changed by updating the image's look-up table (LUT),so pixel values are unchanged. With 16-bit and 32-bit images, the display isupdated by changing the mapping from pixel values to 8-bit display values, so pixel pixel values are also unchanged.Brightness and contrast of RGB images are changed by modifying the pixel values.Press shift-c to open the B&C window the quick and easy way. If it is already open, it is activated.The line graph at the top of the window, which us superimposed on the image's histogram, shows how pixel values are mapped to 8-bit (0-255) display values.The two numbers under the plot are the minimum and maximum displayed pixel values. These two values define the display range, or "window". ImageJ displays images bylinearly mapping pixel values in the display range to display values in the range 0-255.Pixels with a value less than the minimum are displayed asblack and those with a value greater than the maximum are displayed as white.There are four sliders. Minimum and Maximum control the lower and upper limits ofthe display range.Brightness increases or decreases image brightness by moving thedisplay range. Contrast increases or decreases contrast by varying the width of the display range.The narrower the display range, the higher the contrast.Click on Auto, and ImageJ willautomatically optimize brightness and contrast based on an analysis of the image's histogram. Create a selection, andthe entire image will be optimized based on an analysis of the selection. The optimization is done by allowing a smallpercentage of pixels in the the image to become saturated (displayed as black or white). Each additionalclick on Auto increases the number of saturated pixels and thus the amount of optimization.Click on Reset to restore the originalbrightness and contrast settings. The display range is set to the full pixel value range of the image.A resetMinAndMax() macro call is generated if the command recorder is running.Click on Set to enter the minimum and maximum display range values in a dialog box. A setMinAndMax() macro call is generated if the command recorder is running.Click on Apply toapply the current display range mapping function to the pixel data.If there is a selection, only pixels within the selection are modified. This option currently only works with 8-bit images and stacksand with RGB stacks. This is the only B&C option that alters the pixel data of non-RGB images.With DICOM images, ImageJ sets the initial display range based on the Window Center (0028,1050) and Window Width (0028,1051) tags. Click Reset and it sets the display range to the minimum and maximum pixel values. As an example, the File>Open Samples>CT image has a Window Center of 50 and Window Width of 500, so the display range is set to -200 to 300(center-width/2 to center+width/2). Click Reset and the display range is set to -719 to 1402. Press 'h' (Analyze>Histogram) and you will see that the minimum pixel value in the image is -719 and the maximum is 1402. To display the DICOM tags, press 'i' (Image>Show Info). Press 'r' (File>Revert) to revert to the initial display range.Threshold...Use this tool to automatically or interactively set lower and upper threshold values, segmenting the image into features of interest andbackground. The thresholded features are displayed in red and background is displayed in grayscale.Use Analyze>Measure (with "Limit to Threshold" in Analyze>Set Measurements checked) to measure the aggregate of the selected features. Use Analyze>Analyze Particles to measurefeatures individually. Use the wand tool to outline a single feature.Use the upper slider to adjust the minimum threshold value and the lower one to adjust the maximum.Hold the alt key down while adjusting the minimum to move a fixed-width thresholding window across the range of gray values. Check Dark Background if the features are lighter than the background. Thanks to Gabriel Landini, the drop down menu on the left allows any of 16 different automatic thresholdingmethods to be selected. These methods are described on Gabriel's Auto Threshold pluginwebsite. The "Default" method isthe modified IsoData method used by ImageJ 1.41 and earlier.Use the drop down menu on the right to select one of three display modes. Red displays the thresholdedvalues in red. B&W switches to a mode where features are displayed in black and background in white.Over/Under displays pixels below the lower threshold value in blue, thresholded pixels in grayscale,and pixels above the upper threshold value in green.The Auto button uses the currentlyselected thresholding method to automaticallyset the threshold levels based on an analysis of the histogram of the currentimage or selection. Apply sets thresholded pixels to black and all other pixels to white. Reset disablesthresholding and update the histogram. Click on Set to enter new threshold levels into a dialog box.Size...Scales the active image or selection to aspecified width and height in pixels.Check Constrain Aspect Ratio to create an image with the specified width and have ImageJ adjust the height tomaintain the original aspect ratio. Check Interpolate to use bilinear interpolation. Set New width to 0to create an image with the specified height and have ImageJ adjust the width to maintain the original aspect ratio.Canvas Size... Changes the canvas size of an image or stack without scaling the actual image. The width and height may be either expanded or contracted. If the canvas size is increased, then the border is filled with the current background color. Or, if Zero Fill is checked, the border is filled with pixels that have a value of zero. Use the Image>Color>Color Picker tool to change the background color. The position of the old image within the new canvas may also be specified. Show Info...Opens a text window containinginformation about the active image. For DICOM and FITS images, also displays file header information. Use the popup menu(right-click in the Info window) to save the information to a text file or copy it to the system clipboard.Properties...Use this command to display and set various properties of the current image or stack. The number of Channels, Slices and Frames (c, z, and t) in the image can be changed as long as the product of c, z, and tis equal to the number of images in the stack.The Unit of Length (a string describing the measuring unit), Pixel Width, Pixel Height and Voxel Depth(all in the Unit of Length unit) can be set. The width, height and depth are automatically convertedif Unit of Length is changed from one known unit ("nm", "um", "micron", "mm", "cm", "meter", "km" or "inch") to another.With t-series stacks, the Frame Interval in seconds (reciprocal of the frame rate) can be viewed and set.Origin (always in pixels) is the reference point (0,0) of the image coordinate system.Check Global to make the current settings global (i.e., apply to all images opened during the current session).Color SubmenuThis submenu contains commands that deal with color images.Split ChannelsSplits an RGB image into sepate channels (images).Also splits RGB stacks into three separate stacks.The image names have " (red)", " (green)" and " (blue)" appended to them. With composite images and/or hyperstacks (e.g., the "Organ of Corti" sample image),this command splits the stack into sepate channels.Merge Channels...Merges 1-4 greyscale images or stacks into an RGB image or stack.Select *None* to keep a channel empty (filled with 0).Check "Create Composite" to convert 2-4 grayscale images or stacks into a composite image or hyperstack.Check "Keep Source Images" if you wish to keep the originals.Arrange Channels...This command allows you to change the order of the channels in a hyperstackby entering the channel numbers in a different order.Channels that do not appear in the bottom row of thumbnail images will be deleted. Click on any thumbnail image to change that channel's color LUT.When calling this command from script or macro, you also can duplicate channels, e.g.: run("Arrange Channels...", "new=12333");
Channels Tool...Opens the "Channels" window, or brings it to the front if it is already open.Shift-z is the keyboard shortcut for this command.Stack to RGBConverts a two or three slice stack into an RGB image,assuming that the slices are in R, G, B order.The stack must be 8-bit or 16-bit grayscale.Also converts composite images (e.g., the HeLa Cells sample image) into RGB.Make CompositeConverts an RGB image, a 2-7 image stack or a 2-7 channel hyperstackinto a composite color image. Use the "Channels" tool (press shift-z top open) toenable and disable the channels of a composite image. Use the "B&C" tool(press shift-c to open) to adjust the brightness and contrast of the current channel.
In the example above, all but the red and blue channels of a five channel composite image havebeen disabled using the "Channels" tool and the "B&C" tool is being usedto adjust the brightness and contrast of the blue channel.Show LUTDisplays a plot of the active image's lookup table. The lookup table, or color table, describes the color that is displayed for each of the 256 possible pixel values. For 16 and32 bit images, the range of displayed pixel values is mapped to 0-255. A bar under the plot displays the color representation of the pixel values. Note that RGB color images do not use a lookup table. Edit LUTOpens the ImageJ LUT (Lookup Table) Editor. A lookup table (LUT) in ImageJhas up to 256 entries. The entry index, and the three values (red, green and blue) associated with it,are displayed in the ImageJ status bar as you move the cursor over the LUT Editor window.Click on an entry to edit the red, green and blue values for that entry.Drag across several entries and you will be asked to define the RGB starting and ending values for theselected range. The Editor will fill the remaining entries using the selected interpolation method(Replication, Interpolation or Spline Fitting).You can define the number of entries in the LUT usingthe "Set" option. When increasing the number of entries, the Editor uses the specified interpolationmethod. Replication just repeats the entrieswhile Interpolation and Spline Fitting produce gradations between the colors.The "Invert" button sets the inverse of the LUT RGB entries. "Open" and "Save" allow importing or exporting the LUTs.Color Picker...The Color Picker tool enables theuser to select foreground and background colors, which affect Edit>Fill, Edit>Draw and other color drawing commands. It displays current foreground and background colors inthe selection boxes at the bottom of the window. It has two modes:foreground and background. To change modes, click on the desiredselection box. Clicking on the Foreground/Background Switcher button sets the current foreground to the background and vice versa. The Black/White Reset button sets the foreground to black and the background to white.The color palette is based on HSB (Hue, Saturation and Brightness) color model. Hue increases as you go down the palette while saturationand brightness values are split horizontally. The left half of the palette varies onlyin brightness while the right half varies only in saturation. At thecenter of the color ramp are enlarged red, green, blue, cyan, magenta,and yellow colors for quick selection. To the left of the color palette is a grayscale ramp that goes from pure black to pure white.Double-clicking on a color brings up the Color Selector, shown on the right inthe illustration. Use the sliders to specify the RGB values ofthe foreground or background color. To get precise colors, manually change the values in the text boxes. The title of the Color Selector window ("Foreground Color" or "Background Color") indicates the current selection mode.The Color Picker was written by Gali Baler, a 2003-2004 intern from Bethesda-Chevy Chase High School.Stacks SubmenuThis submenu contains commands that workwith stacks. Add SliceInserts a blankslice after the currently displayed slice. Hold down the alt key to add the slice before the current slice.Delete SliceDeletes the currently displayed slice.Next SliceDisplays the slice that follows thecurrently displayed slice. As a shortcut, press the ">" key.Previous SliceDisplays the slice that precedes thecurrently displayed slice. As a shortcut, press the "
