مشکل در ذخیره اسکرین شات

[vistamobile 1,700]

سلام. من به یه پنل خاصیت پخش دوربین رو دادم. بعد یه پنل دیگه روساختم و به اون پنل خاصیت لمس دادم ( با لمس پنل دوم تصاویرش عوض بشه) بعد یه باتون ساختم و به باتون گفتم که اگر لمس شدی، یه عکس از پنل دوم بگیر. فکر میکردم با این کار از دوربین هم عکس گرفته میشه. یعنی یه اسکرین شات که هم عکس پنل اول توشه و هم دوم:

 

یعنی فقط تصویر پنل دوم میافته نه تصویر دوربین. در ادامه اومدم و پنل دوم رو کلا حذف کردم و خاصیت دوربین و لمس رو به پنل اول دادم ولی کلا عکسهایی که به برنامه دیدم قابل مشاهده نبود. فقط تصویر دوربین رو میدیدم. وقتی هم از اسکرین عکس میگیرم فقط یه تصویر سیاه میده. چرا؟

دوستان مث اینکه چندتا پستم پریده. کسی هست اینجا کمک کنه؟؟  

[Nemesis 1,846]

خوب برادر معلومه که بها فقط پنل اولیه رو میده شما باید بعد از کامل شدن عکس در پنل دوم اون رو در Canvas برگردونی و بعد به bitmap ذخیره کنید

[vistamobile 1,700]

داداش یه تیکه کد میشه بدی؟ من اینجورکی نوشتم:

Sub SavePanel(Sv As View,sDir As String,sFilename As String) As Bitmap
   Dim o1, o2 As Reflector
   Dim bmp As Bitmap
   Dim C As Canvas
   o1.Target = o1.GetActivityBA
   o1.Target = o1.GetField("vg")
   bmp.InitializeMutable(Sv.Width+20, Sv.Height+20)
   C.Initialize2(bmp)
   Dim args(1) As Object
   Dim types(1) As String
   o2.Target = C
   o2.Target = o2.GetField("canvas")
   args(0) = o2.Target
   types(0) = "android.graphics.Canvas"
   o1.RunMethod4("draw", args, types)
   Dim Out As OutputStream
   Out = File.OpenOutput(sDir, sFilename, False)
   bmp.WriteToStream(Out, 100, "PNG")
   Out.Close
End Sub

Sub Ax_btn_Click
	SavePanel( Panel2,File.DirRootExternal& "/DCIM","Samlpe.png")
    Msgbox("با موفقیت ذخیره شد در پوشه DCIM","پیام ")
End Sub

پیشنهد میدم برای راحتی کار از کتابخونه RSImageProcessing استفاده کنی و یه سر به اینجا بزنی اگه نتونستی تا فردا همینجا یکاریش میکنم برات

RSImageEffects

Methods:

Blur (src As Bitmap, Factor As Int, Offset As Int) As Bitmap

Does a Gaussian Blur to the image. - Filter

It uses the concepts of Convolution Filtering to apply in image processing.

Brightness (src As Bitmap, value As Int) As Bitmap

The concept of brightness is rather simple, increasing/decreasing value of each R, G, B channel together.

+ By increasing: image results brighter.

+ By decreasing: image results darker.

Effects

ColorBoost (src As Bitmap, type As Int, percent As Float) As Bitmap

Color boost technique is basically based on color filtering, which is to increase the

intensity of a single color channel.

Effect

Contrast (src As Bitmap, value As Double) As Bitmap

Contrast is the difference in luminance and/or colour that makes an object (or its representation in an image or display) distinguishable.

In visual perception of the real world, contrast is determined by the difference in the colour and

brightness of the object and other objects within the same field of view.

Effects

Emboss (src As Bitmap) As Bitmap

Embosses your bitmap to make it look sketchy like.

Filter

Engrave (src As Bitmap) As Bitmap

Engraves your bitmap.

Filter

Flip (src As Bitmap) As Bitmap

Effect

GammaCorrection (src As Bitmap, red As Double, green As Double, blue As Double) As Bitmap

Gamma correction or gamma encoding is one among the common image processing method

Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma,

is the name of a nonlinear operation used to code and decode luminance or tristimulus values in video or

still image systems.

Effect

Effects

Highlight (src As Bitmap) As Bitmap

Highlights a bitmap.

Effects

Invert (src As Bitmap) As Bitmap

Inverts a bitmap.

Every image pixel holds information of four channels: Alpha, Red, Green, Blue.

However, Alpha doesn�t reflect the image color as display. So the value is kept, and take inversion for other three

channels by formula: 0xFF � CurrentValue.

Mirror (src As Bitmap) As Bitmap

Flips a bitmap horizontally.

Effect

Noise (source As Bitmap) As Bitmap

Gives a noise or flea effect to the bitmap

Effect

Paintify (src As Bitmap, bitOffset As Int, Factor As Int, Offset As Int) As Bitmap

Decreasing color depth involves converting to standard values.

For example: if I want to offset 32, then each image color channel will apply the range: 0, 31, 63 �

Effects

Reflection (originalImage As Bitmap, ReflectionGap As Int) As Bitmap

Makes a mirror/reflection like

ReflectionGap: gap space between original and reflected

Effect

Effect

RSImageFilters

Methods:

BlackFilter (source As Bitmap) As Bitmap

Base on randomizing image pixels, another filter is created, named �Black Filter�, or enhance the noise of darkness.

The algorithm is to generate a threshold number (0-255), if all R,G,B values of a pixel are less than the threshold,

then set the pixel to black.

EventName - Events subs prefix.

compress (bitmap As Bitmap, format As String, quality As Int, stream As OutputStream)

Write a compressed version of the bitmap to the specified outputstream.

format The format of the compressed image

quality Hint to the compressor, 0-100. 0 meaning compress for small size, 100 meaning compress for max quality. Some formats, like PNG which is lossless, will ignore the quality setting

stream The outputstream to write the compressed data.

createScaledBitmap (src As Bitmap, dstWidth As Int, dstHeight As Int, filter As Boolean) As Bitmap

Creates a new bitmap, scaled from an existing bitmap.

src The source bitmap.

dstWidth The new bitmap's desired width.

dstHeight The new bitmap's desired height.

eraseColor (bitmap As Bitmap, c As Int)

Fills the bitmap's pixels with the specified Color.

bitmap: the source bitmap. (must be mutable!)

c: colours

extractAlpha (bitmap As Bitmap) As Bitmap

Returns a new bitmap that captures the alpha values of the original.

bitmap:

extractBitmap (source As Bitmap, x As Int, y As Int, width As Int, height As Int) As Bitmap

Returns an immutable bitmap from the specified subset of the source bitmap.

The new bitmap may be the same object as source, or a copy may have been made.

It is initialized with the same density as the original bitmap.

source:

x:

y:

width:

height:

Return type: @return:

extractBitmap2 (source As Bitmap, x As Int, y As Int, width As Int, height As Int) As Bitmap

Returns an immutable bitmap from the specified subset of the source bitmap.

The new bitmap may be the same object as source, or a copy may have been made.

It is initialized with the same density as the original bitmap.

source:

x:

y:

width:

height:

Return type: @return:

getDestination (src As Bitmap, destination As Double) As Int

Gets the new destination width or height keeping the aspect ratio of the image.

src: - bitmap

destination: -Source width or height

Return type: @return:

getPixel (bitmap As Bitmap, x As Int, y As Int) As Int

Returns the Color at the specified location.

Throws an exception if x or y are out of bounds (negative or >= to the width or height respectively).

bitmap:

x: The x coordinate (0...width-1) of the pixel to return

y: The y coordinate (0...height-1) of the pixel to return

Return type: @return:The argb Color at the specified coordinate

hasAlpha (bitmap As Bitmap) As Boolean

Returns true if the bitmap's config supports per-pixel alpha, and if the pixels may contain non-opaque alpha values.

For some configs, this is always false (e.g. RGB_565), since they do not support per-pixel alpha.

However, for configs that do, the bitmap may be flagged to be known that all of its pixels are opaque.

In this case hasAlpha() will also return false. If a config such as ARGB_8888 is not so flagged, it will return true by default.

bitmap:

Return type: @return:

isMutable (bitmap As Bitmap) As Boolean

Returns true if the bitmap is marked as mutable (i.e. can be drawn into)

bitmap:

Return type: @return:

isRecycled (bitmap As Bitmap) As Boolean

Returns true if this bitmap has been recycled. If so, then it is an error to try to access its pixels, and the bitmap will not draw.

bitmap:

Return type: @return:true if the bitmap has been recycled

recycle (bitmap As Bitmap)

Free the native object associated with this bitmap, and clear the reference to the pixel data.

This will not free the pixel data synchronously; it simply allows it to be garbage collected if

there are no other references. The bitmap is marked as "dead", meaning it will throw an exception if

getPixels() or setPixels() is called, and will draw nothing. This operation cannot be reversed,

so it should only be called if you are sure there are no further uses for the bitmap.

This is an advanced call, and normally need not be called, since the normal GC process will free

up this memory when there are no more references to this bitmap.
