Compressing Images in Flash

if you have the checkbox for use imported jpeg data selected
within the info for an image, does this mean that there will be
ZERO compression applied to the image from Flash when it is
exported?
Thanks.

This from the Flash help file:
The JPEG format lets you save an image as a highly
compressed, 24-bit
bitmap. Generally, GIF format is better for exporting line
art, and JPEG
format is better for images with continuous tones, such as
photographs,
gradients, or embedded bitmaps.
Flash exports the first frame in the SWF file as a JPEG,
unless you mark a
different keyframe for export by entering the #Static frame
label.
1.. Select File > Publish Settings, click Formats, and
select JPEG Image.
2.. For the JPEG filename, either use the default filename,
or enter a new
filename with the .jpg extension.
3.. Click JPEG. Dimensions Enter values for width and height
in pixels for
the exported bitmap image, or select Match Movie to make the
JPEG image the
same size as the Stage and maintain the aspect ratio of your
original image.
Quality Drag the slider or enter a value to control the
amount of
JPEG file compression. The lower the image quality, the
smaller the file
size, and the reverse. To determine the best compromise
between size and
quality, try different settings.
Note: To change the object's compression setting, use the
Bitmap
Properties dialog box to set the bitmap export quality per
object. The
default compression option in the Bitmap Properties dialog
box applies the
Publish Settings JPEG Quality option.
Progressive Show Progressive JPEG images incrementally in a
web
browser, which makes images appear faster when loading with a
slow network
connection. Similar to interlacing in GIF and PNG images.
4.. Click OK.

Some of Photo (JPEG)-compressed images by Flash Pro are not shown in AIR app (3.7/3.8)

Does anyone see this issue happening? In Flash Pro it's OK, but in AIR, it's broken.
https://bugbase.adobe.com/index.cfm?event=bug&id=3558175
Problem Description:
Some JPEG-compressed images in swc produced by Flash Pro CS6 is not shown in AIR.
Steps to Reproduce:
1. Create a fla with Flash Pro CS6
2. Put a png image in it and open the property of the image to make sure its compression option is Photo (JPEG)
3. Produce an swc out of the fla
4. Create an AIR app that shows the contents in the swc
Actual Result:
All images are shown
Expected Result:
Some of the images are not shown (nothing is shown where they are supposed to be)
Any Workarounds:
Use Lossless (PNG/GIF) for all images

i was able to get it to work from a suggestion in another thread: if you write a JSFL that goes through all your bitmaps and makes sure they do not uset he default compression of the document, but instead use custom compression (it can match the default however). this worked for me

When importing an image into Flash, the filesize is reported incorrectly

I saved an image from Photoshop using "Save for Web" and managed to bring the filesize down to 56.5kb. When I import this image into Flash and click on the properties, the reported "Original" filesize is 1884.6kb which is a heck of a lot more. How can I import the image and retain the filesize without having to compress the image further causing a horrible quality image?

right click one of your bitmaps, click properties and tick "allow smoothing". retest.

How to upload a image or flash file as blob object in a table.
What are all the possible ways we can do it.

Searching the forum (or google) would be my first choice, as this question pops up every now and then.
Next without knowledge of your environment (jdev version and technology stack) it's hard to give a profound answer.
All I can say is that it's possible.

How to show a compressed image in the report?

Hi
I have created a new report.what i do in application is i compress the image and save it in database.now i need to retrieve the compressed image and display in the report. I have used the following code to decompress the binary data save in the image.I
dont know after that what should i do. Please help me to show the picture in SSRS Report. I need to show picture in many reports.one of my doubt is how to call this function in SSRS Report. The function accepts input as byte but in database the column in varbinary.
should i convert the input type of function to varbinary instead of byte array? Please help me.
Public Function Decompress(ByVal arr As Byte()) As Byte()
Dim notCompressed As Boolean
notCompressed = False
Dim MS As MemoryStream
MS = New MemoryStream()
MS.Write(arr, 0, arr.Length)
MS.Position = 0
Dim stream As GZipStream
stream = New GZipStream(MS, CompressionMode.Decompress)
Dim temp As MemoryStream
temp = New MemoryStream()
Dim buffer As Byte() = New Byte(4096) {}
While (True)
Try
Dim read As Integer
read = stream.Read(buffer, 0, buffer.Length)
If (read <= 0) Then
Exit While
Else
temp.Write(buffer, 0, buffer.Length)

Catch ex As Exception
notCompressed = True
Exit While
End Try
End While
If (notCompressed = True) Then
stream.Close()
Return temp.ToArray()
Else
Return temp.ToArray()

Please try this
Public Function Decompress(ByVal arr As Byte()) As Byte()
Dim s As Byte()
Dim notCompressed As Boolean

me, please. Thx Joe

Hi,
The issue here is the mapping of the interface to the service in question, and usually points to a possible mistype or rename of something within your service architecture.
You need to make sure your namespace and service name here match your service name itself.

How to make a link to an image in flash?

Hi,
I´m new in Flash CS3 and I´m trying to get some
answers to my problem.. The question is
that how do I create a link to an image in flash??
I know how to make a link to a text field but I really
don´t know how this could get working properly.. :/

Link to an external URL image? In AS 2 the code is
'getURL("putaddresshere")' and in AS 3 it's 'navigateToURL("")' ...
If it's a simple image, it's easier just to import it to the
stage, save it as a symbol, put it in a timeline frame and then
code your link so on click or rollover it goes
'gotoAndPlay(framenumber)'.

Scrolling Text and Images in Flash CS3

I am pretty new to Flash and I have spent all day trying to
look up tutorials on making it possible to scroll text and images
in Flash but none of them are working for me. I know you save the
content into a movie clip but that's as far as i have gotten. would
anyone be able to walk me through this PLEASE???
Thanks,
Peter

You could use a Swing HTMLPANE or draw it all onto a
BufferedImage and display that (code posted under 2D graphics thread).

Text editable in images in flash Please help

Hello
Dear All Friends
I want to make text editable in images in flash to get copy from text
can i Make this
and other question please
can i convert text in image in flash to normal string ?
please help
Thank you

Images do not store text data in any isolateable manner, it is comprised of just pixels like anything else in the image. You would need to develop some form of complicated text recognition program to be able to extract text from an image, and I don't believe anyone has.

"Compress images in pdf documents" won't work

I created this workflow:
1. Get selected Finder objects
2. Compress images in pdf documents
3. Copy Finder objects to...
... but it won't work, the images are not compressed. Anyone any suggestions?

To examine this I made three pdf documents from three Pages documents (running compression during export to pdf) each containing one image: one psd, one tiff and one jpg image. Running the workflow on these pdfs, the pdfs containing the psd and the tiff files were compressed but not the pdf containing the jpg image. I then made two pdf documents exported from Indesign containing a tiff file; one pdf export compressing and downsampling the tiff image and one with no downsampling and compression. Running the workflow on these two pdfs did not further compress the already compressed pdf, but did compress the pdf containing the uncompressed image. To further optimize pdf documents already compressed on export from Indesign one has to use Acrobat, which, of course, is the most efficient and flexible tool for optimizing pdf documents.

Load Random Image in Flash?

I've googled it and searched this forum. No luck.
Does anybody know how to load a random image in flash. Like
on a welcome screen (i.e. the first thing that shows up in my
timeline with a stop command on it)
I tried this:
http://www.kirupa.com/developer/mx/loadingrandombackground.htm
but can't do this where you are supposed to paste the code in
Actions: "Now, look at your timeline. Right click on a blank
keyframe in the timeline and select Actions. Copy and paste the
following code: "
seems like i have to add something first like adding a
behavior like "goto URL" or "stop" or "goto frame" if you know what
i mean.
what do i click on???????????????????? to add this code into
Actions.
Thanx.

let say you have 20 images file in jpg format, all at the
same directory with your flash file, with file name as below:
pic1.jpg
pic2.jpg
pic20.jpg
in your flash, select the frame which you wan to load a
random image, type script below:
num = Math.ceil(10*Math.random());
filename = "pic" + num + ".jpg";
_root.createEmptyMovieClip("pic_mc", 1);
loadMovie(filename, "pic_mc");
//good luck

Can't import an Image into flash

Exporting images from flash

I'm currently porting a game from flash to the DS and having
difficulties exporting the images and was hoping someone out there
might be able to help. The images in flash are all vector based and
I need to export them and place them on a background (colour
255,0,255). The reason for the background colour is it is removed
programmically within the game (blue screening if you will).
Problem is, if I export them as png's and then add the background
in photoshop, or do a screenshot in flash with the image over the
background then it leaves a halo around the character.
Anyone know how to get around this?
Take care,
S.

Can you upload an example of the png or a visual of the halo
you are seeing?

Can any one tell me how to stream the images in flash.

Hello Friends,
i have created a dynamic page flip book with xml, i want to
zoom the images in swf loaded, with streaming, so that user can
preview the image while a good quality image is loading. I wanna
know that how to load a part of large image or swf.
Image effect like :-

You show a preview and use loadMovie() to load a big file.
You can
create a preloader (progress bar) showing how much part is
loaded,
while user sees the small image. When you achieve 100% tou
show that
big image. What's more?

What are you talking about is not a "streaming", but
"progressive
download". Images "streaming" is impossible.

A Fast way to display compressed images?

Hi,
I currently working on iPhone and trying to display (home-made) compressed images in an UIImageView : it is updated as soon as I have finished building the new one. I already do it with raw (BMP) images but I use them at 2D GLTextures that I found faster than the use of an UIImageView.
To update the view with compressed images, I do:
//member in .h
UIImage * myImage;
UIImageView * MyImgView;
// In .m
-(void)UpdateImageWithData :(NSData *) p_Data
myImage = [UIImage imageWithData:p_Data];
MyImgView.image = myImage;
This works quite well, but I encounter a major drawback for me : the frame rate of this is never better than 10 fps. I build my images faster that 25 per second, but cannot display them that fast.
I tried to change compression quality and compression methods (PNG interlaced or not, JPEG (411, 421, 444, varying quality from 10 to 100%), etc.) but I always have the same frame rate. So, I am assuming that the max frame rate you can have with an UIImageView is limiter whatever the format is.
Now, I am wondering a few things :
- Am I right about this limitation or do you see any flaw in my discussion?
- Is there some way to 'accelerate' the rendering with an UIMageView?
- Is there another faster way to display compressed images (or at least any kind of JPEG images)
- Is there a (fast) way with UIKit (or any compatible lib) to retrieve the raw image so that I can use my first method and display it as a 2D OpenGL Texture?
- Since from one image to the other only a few changes occur, do you see any way to update only what actually changed in order to save some CPU?
- Do you think that the problem about UIImageView frame refreshement rate is linked with the iPhone Video Processor or with its CPU? (thus the new 3GS may help me solve this problem)
Thank your for reading this untill the end.

Hey, guess what, I had pretty much this same exact problem. Client wanted full screen 30 fps animation. Here's what I found experimenting with full screen sizes:
- Whether you use UIImageView conveniences, or load and draw yourself in a UIView subclass, makes no apparent difference.
- If you're doing basic Quartz drawing, never a problem keeping 30 fps up.
- But as soon as you change the image in a UIImageView, or draw it with CGContextDrawImage() yourself in a UIView, then the frame rate plummets to about 10 fps on an iPod touch 1G, or 20-25 on an iPhone 3GS.
For my purposes most of the full screen animation could be put into movies, and the motion clipped down to manageable sections in the interactive portions (and anyway, the fps doesn't really matter for those background bits). If it's not for you, then I guess you need to go down to OpenGL and see how that works out.
