BITMAP issue

GUY'S
I am facing a strange problem. i am working on server
on which they created my user-id with developer access,
user told me to change the form and to add signature
in form,
i have uploaded this signature using se78 tcode,put
when i go for print preview ,i am not able to see
preview of my signature,intresting point to be noted is that test case sended by user is having logo,which is not
appearing with my EID,when we confirm these with the user
,he told that even ,he's unable to see any bitmap image's
but ,when he take print out,he's getting logo,
but strange thing is that when i take print
out ,i am getting nothing.
so i decided to create a dummy print program and form
in some other server ,and this server,print program and
form are same in both server,but i am getting print
preview in other server and even output ,but nothing in these server.
conclusion is that problem may be with authorization
,i asked basis team,they gave me what ever possible,
but nothing worked out

Hi Sanju ,
BITMAP is Client Independent, So problem with the Layout, So Do Client Copy properly thru SCC1 and check.

Bitmap Issues

I have Flash Pro MX 2004 and I used to be able import an
image file (jpg, png) to library and then drag it to the scene to
work on it. Now for some reason I can not open it in my scene. I
just can not figure out why. I tried the same image in previous
flash files that were completed and it shows up. but I create a new
project and try to display the image in scene all I get is a the
outline square. I am about to lose my mind. I have no virus and
cant' really figure out why. Can someone help?

Emil, Thank you for your quick reply. You know it is strange
but I have not even touched that feature. I was not aware of it.
What is even weird is I can open the image in my old completed
flash files but any new flash file that I create, theimages will
not open. Any image. Any ideas

Query Fast In SQLPlus and Toad but Slow Otherwise

Environment is Oracle 10g on AIX with 10g drivers on Windows XP as the client. Several queries run in less than 9 seconds in Toad and SQLPlus but take hours or never return in Business Objects Deski, MS Access, and SQL Server SSIS. The exact same SQL produces completely different explain plans based on if it is run from Toad/SQLPlus vs the other products I mentioned. All the software is on the same XP machine and does not use middleware. 99 percent of our queries will run fast or slow in all products. What is it that Toad and/or SQLPlus does to run the queries fast? Why does Oracle change explain plans based on what application connects to it? The goal is to run Business Objects reports from Oracle. Any help or direction for further troubleshooting would be appreciated. Thank-you.

Charles, on the XP machine I selected the Admin option when installing the client. The software should be 10g R2. Below is the information requested. If you need more please let me know. Also, I am asking our DBA to check the bitmap issue.
I appreciate the help. Thank-you for taking your time...

I didn't have problems with CS 5 and Lion, but I do now with Mountain Lion. I've got bitmapping issues across the board.

TechTool Deluxe destroyed my Volume

Hi... I stupidly used the TechTool Deluxe v 3.03 (that came with my Apple Care Plan) on my G5 Dual running Tiger 10.4.7.
Basically - I installed a Microsoft Office update last night. This morning I was greeted with a black screen over my desktop and application screen that contained the text "kernel panic".
I restarted my Mac and then ran Disk Utility to repair permissions etc.
(Obviously it wouldn't do it as it was my startup disk.)
So I started up from my G5 install disk (10.4) and tried running Disk Utility from there. It was unable to repair - stopping part way through and mentioning something about a bad or illegal "exit" or something.
Alongside the G5 install disks was the Apple Care branded TechTool Deluxe CD (v3.03). I figured - if it's good enough for Apple to be giving out with its 3 year extended warranty...
So I inserted that and ran it on my drive - which - apart from the Disk Utility 'error' - had been working fine. (I know - if it works, don't fix it, right?)
I ran the test - watched it go through the pretty icons until it got to the Volume test... 2 hours later it was stilll on task 5 of 6 and had completed 126543789 of 6457382546 tasks.
At the end of all that - it came up with a diagnosis - which was pretty similiar to all the other disk utility screens. You've got x when you should have y. This is bad. The fact that you have j when you should have p is not so bad. But you should fix this.
So I pressed the 'fix' button.
When I restarted after the TTD assault was over - I was greeted with a tiny rectangular black screen in the centre of my display and no cursor. Eventually the fan started screaming and spinning louder and harder so I shut the computer down. Nothing I could do seemed to have any effect.
That was 15 hours ago.
Since then I have started the G5 in Target Mode and tried to repair it with Disk Warrior. Disk Warrior tells me that, in essence, another utility has destroyed the volume file structure and cannot repair it. I have tried to repair it using an updated version of TTD. This seemed to fix the problem - went through the whole file thingy and a recommendation and did the repair.
To no avail.
I made a disk image from a version of TTD downloaded from Apple at https://support.apple.com/techtooldeluxe/main?id=dl and tried to start the G5 up from that and run the utility. Same thing: it ran the tests and made recommendations - which I agreed to. It made its repairs. I restarted - but nothing - just that black screen and a the threat of my tower taking off - judging by the noise the fan was making.
Now I have searched all over the web for a solution to this.
I found a thread at a macintouch forum that covered an identical issue. (http://www.macintouch.com/readerreports/technicalsupportissues/topic3006.html)
One of the posters claimed to have found a magic cure for what everyone at Apple was telling him was a dead duck issue. "Dead hard drive. Sorry about the TTD thing, but we don't suggest you use it. And we knew that this problem existed. But we still gave you an ill-suited version of TTD as a 'perk'(incentive) for buying the extended warranty...
Apparently someone at Micromat had a way of fixing this problem. I quote:
"To resolve the issue I removed the Attributes file from the structure and then let the drive recreate a new Attributes file. Once a new Attributes file was created, the hard drive remounted on the desktop as expected. I did run the soon-to-be released TechTool Deluxe 3.0.4 on this hard drive afterwards and it encountered a volume bitmap issue which it was able to repair successfully."
Does anyone have any suggestions? Help? Please!
Of course - explaining how Apple can knowingly supply a defective Apple-branded tool (bearing no warnings or System Version limitations) that does exactly the OPPOSITE of what it is being used for (destroying instead of repairing) is going to be very difficult.
Right now I would love to be able to recover my life's work. Music. Photos. Writing.
Thanks!

G5 Dual 2.5GHz, 2.5 GB RAM Mac OS X (10.4.7)

I was contacted by Marc Moorash from Alsoft, who guided me through the following process. (Well - at least up to Step 10 below).
The whole process probably took an hour from start to successful finish. I was on the phone to him for about 3 minutes!
1. Connected damaged G5 to Powerbook via Firewire 400 using Target Mode.
2. Launched Disk Warrior 3.03 from CD on the Powerbook
3. Selected the drive (Unknown Disk) to be repaired
4. Held down Ctrl+Opt and clicked on the DiskWarrior shield next to "Directory"
5. A hidden screen popped up asking for a password. It gave an 8 character hint:
6. The tech support asked for the hint and then supplied me the password.
7. A new menu appeared, called "Support". In that menu there was an option: "Clear Corrupted Volume Header ", which I selected.
8. I was then asked to click "Rebuild" and to call out each Step in the process to the tech support guy.
9. It almost immediately jumped to Step 5: Locating directory data.
10. Evidently this was good...as it meant that it had bypassed the error message I was getting previously.
11. Eventually DiskWarrior finished analyzing the volume and presented me with the option to preview the rebuilt volume:
12. I clicked on the "Preview" button and DW created a locked disk in the Finder.
13. I checked the volume: everything was fine.
14. I clicked on the "Replace" button.
15. My hard drive appeared on the desktop, and in the DiskWarrior menu.
16. I am now backing up all the data that I thought I had lost.
Thanks to Marc Moorash and the tech support team at Alsoft.
No thanks to AppleCare and TechTool Deluxe.

Adobe AIR for Android - GPU Mode - Bitmap Auto-Smoothing Issue

Hi everyone
I'm having a bit of an issue with the AS3 bitmap object. I'm currently developing an 8-bit style pixel game for AIR for Android.
This game is being developed at a very low resolution and is being scaled up to maintain the charm of an old retro game.
One of the methods I'm using is drawing pixels directly to bitmap objects and scaling the object up to create the old look.
When testing on a mobile device, this works beautifully when you set the rendering method to Direct but when you change
the render method to GPU the visuals go all blurry and anti-aliased (it's as if the bitmap is being smoothed out). The mini map
for example is rendered using the setPixel method and then scaled up 9 times. Looks great on my PC but once I export it to my phone
it looks absolutely awful! This is no good as I want to keep the clean, solid pixel look to maintain the the old 8-bit feel and obviously
I'd like to stick to GPU mode due to it's speed.
Like I said, this only happens once you test on a mobile device in GPU mode - it doesn't do it on my main desktop machine or
in Direct mode. I already have the stage quality set to low and I've tried setting the bitmap's smoothing property to false but
it does nothing.
Does anyone have any suggestions as to how I can get around this?

How about first blit your image to a small bitmapData, then draw it on a large bitmapData (9X larger)?
Like,
var small_bmd:BitmapData = new BitmapData(SMALL_WIDTH, SMALL_HEIGHT, false);
var large_bmd:BitmapData = new BitmapData(SMALL_WIDTH * 9, SMALL_HEIGHT * 9, false);
var bm:Bitmap = new Bitmap(large_bmd, PixelSnapping.NEVER, false);
var blitRect:Rectangle = new Rectangle(0, 0, 9, 9);
var i:uint, j:uint, blitColor:uint;
small_bmd.draw(SOURCE_IMAGE);
large_bmd.lock();
for(j = 0; j < SMALL_HEIGHT; j++){
     for(i = 0; i < SMALL_WIDTH; i++){
          blitColor = small_bmd.getPixel(i, j);
          blitRect.x = i * 9;
          blitRect.y = j * 9;
          large_bmd.fillRect(blitRect, blitColor);
large_bmd.unlock();
Not sure if the code works or not, but hopefully this helps.

Streaming Video and Bitmap Draw issues.

Hello all,
In the current application I'm developing, I have a custom
video console. While watching a video, certain points in the
timeline will pop up a dialog box that gives the user the ability
to switch to a related video. If the user clicks the button to view
the related video, a 3D effect flips the current "main" console to
a secondary "branching" console - much like the flip effect the
iPhone uses. The videos are streaming from FMS 3, the client
application was developed in Flex, and we are using Alex Uhlmann's
Distortion Effects to achieve the 3D flip effect.
When I first started developing the application, I ran in to
the infamous "Security sandbox violation: BitmapData.draw" error
whenever I would try the flip. After some investigation on the web,
I found that I needed to set the Client.videoSampleAccess property
in my FMS application's main.asc to allow bitmap snapshot access. I
did so, and that seemed to do the trick. After playing with the
application a bit more, however, I found that the error would still
come about if I did the following:
1. Pause the video (stream)
2. Perform a seek while paused.
3. Attempt the flip effect.
When I did the above, the error came back. If I paused,
performed a seek, and then unpaused the video, everything worked
fine. If I pause and then immediately do the flip without a seek,
everything works fine.
It seems as though when you pause and then perform a seek,
the player forgets that it has permission to do a frame grab until
you restart playback.
Has anyone else had this issue, or anything similar? If so,
how did you solve it?
Thanks,
--G
(For reference, here is the actual Error that is getting
thrown)

Hi,
I've been searching all over for someone having the same
problem that I am.
I'm seeing nearly the same thing that you are. I have
SWFVerification turned on and the swf copied over to the correct
directory. If I stream an FLV and attempt to capture grab the
bitmap data it works fine. Always.
If I try the same thing with a .mov or .mp4 file it mostly
works, but sometimes (after doing basically the same thing you've
described in your message), I get the SecurityError. If I try again
after a delay of a few seconds, sometimes it works. When that
doesn't work, if I seek a 1/10th of a second ahead in the video
then try again, it almost always works. But sometimes that, too,
fails.
Have you found a reliable solution to your problem? Has
anyone else seen this issue? I would file a bug for FMS, but it
looks like the bug-tracking system for FMS is not public. It would
be nice for it to be public.
regards,
david

DV PAL Widescreen 16:9 Bitmap Export Issue

I've searched past questions concerning this issue, but unfortunately past questions have not yielded a definitive answer or workable solution in my case.
I have a project shot in DV PAL Widescreen format on a Sony HVR-Z5E. My Sequence settings are: 720x576 DV1/DV PAL 16:9 (1.4587). Captured video is showing as 720x576 (1.4587) AVI 25fps.
I am creating a freeze frame by exporting to Windows Bitmap from the sequence. I am setting Media export aspect as DV PAL Widescreen 16:9 (1.4587) - the same as the source setting. In the output monitor source/output looks identical. So it looks like I am exporting correctly - I can only assume.
But having done the export, the bitmap image looks 4:3 with squeezed sides. Importing back into the sequence confirms this - it's 720x576 (1.094). I have exported using both Widescreen setting and Square Pixel setting, both produce 4:3 aspects.
Why is AME not exporting in the correct aspect according to the settings? Why is it maintaining a 4:3 aspect? How can I successfully export to Bitmap and retain the existing 16:9 and bring it back into my project?
Additional: I do not require my export to pass through any other software, just to capture the still frame and import it back into the project.

Thanks so much you guys - yep, that fixed it. The import after interpretation fixed the issue and I have a beautiful integrated freeze frame in the correct aspect. Thanks also Colin for the TIFF solution.
Now as to who gets the "Correct Answer" points? You will agree, that three helpful and correct answers all within about 5 minutes of each other should warrent equal thanks - don't you agree? If I click "Helpful Answer" for all three of you, will that work? Will the system allow this?
If not, then please accept my thanks and appreciation. I'll let God sort it out later

in both explain plan only difference is
9 BITMAP CONVERSION TO ROWIDS
8 BITMAP AND
5 BITMAP CONVERSION FROM ROWIDS
but is bitmap degrading performance lot?
or suggest me what other parameter i can see so 2nd instance gives me better performace.

I see more differences.
In plan 1:
* 16 INDEX RANGE SCAN idx_bf_creation_date 76 1 (0) 00:00:01
in Plan 2:
1 INDEX FULL SCAN (MIN/MAX) INDEX REPORTSDB.idx_bf_creation_date Cost: 3 Bytes: 8 Cardinality: 1
So this is not about "bitmap" good/bad, it about the access strategy which changed due to differences in data statistics etc. To analyze more, I'd help a LOT if those plans would be formated in a good and same way, use around it to do so.

Publish issue with Cap 6: Background bitmapped/not showing/copied from previous slides

Hi,
I have been working on a course for a while, publishing and having no issues. This morning when I tried to publish a few of the lessons, I am noticing that there are parts of the background from one slide appearing on the next. Also, on some slides, I see a couple of square areas of the background and nothing else. The captions and voiceover are fine though.
Can someone please help - the course is due today!
Thank you
Michele

I believe I have figured out the resolution, although not sure why it happened?
When I publish, I choose the setting "Force re-publish all the slides", the screens are fine - no issues. I think I will just check this all the time

A generic error occurred in GDI+ while assing tiff image file to Bitmap and Image

Hi,
I am getting "A generic error occurred in GDI+" error while reading the tiff image file to Bitmap or Image.
Below is my sample code.
string filePath=@"c:\Images\sample.tif";
Bitmap bmp=new Bitmap(filePath); // here getting exception
int totalpages=bmp.GetFrameCount(.....);
etc......
I tried using Bitmap.FromFile() and also from FromStream() even for Image also but there is no use.
Moreover i m having full permissions for the file path and the tiff file is having multiple pages.
Can anyone help me to solve this issue please.
Thanks & Regards,
Kishore

Make sure that the Tif file is valid (can other software open it)? If you are able to save a Tif using GDI+, try saving that Tif, then opening it. Part of me wonders if there is something about that specific Tif that GDI+ doesn't like.
You could also try using WIC to open the TIF, perhaps you would have better luck there.

Multi-column BITMAP index vs. multiple BITMAP indices?

Given the table (simple, made-up example):
CREATE TABLE applicant_diversity_info (
applicant_diversity_id NUMBER(12), PRIMARY KEY(applicant_diversity_id),
apply_date DATE,
ssn_salted_md5 RAW(16),
gender CHAR(1), CHECK ( (gender IS NULL OR gender IN ('M','F')) ),
racial_continent VARCHAR2(30), CHECK ( (racial_continent IS NULL
OR racial_continent IN ('Europe','Africa','America','Asia_Pacific')) ),
ethnic_supergroup VARCHAR2(30), CHECK ( (ethnic_supergroup IS NULL OR ethnic_supergroup IN ('Latin American','Other')) ),
hire_salary NUMBER(11,2),
hire_month DATE,
termination_salary NUMBER(11,2),
termination_month DATE,
termination_cause VARCHAR2(30), CHECK ( (termination_cause IS NULL
OR termination_cause IN ('Resigned','Leave of Absence','Laid Off','Performance','Cause')) )
Oracle (syntactically) allows me to create either one BITMAP index over all four small-cardinality columns
CREATE BITMAP INDEX applicant_diversity_diversity_idx ON applicant_diversity_info (
gender, racial_continent, ethnic_supergroup, termination_reason );
or four independent indexes
CREATE BITMAP INDEX applicant_diversity_gender_idx ON applicant_diversity_info ( gender );
CREATE BITMAP INDEX applicant_diversity_race_idx ON applicant_diversity_info ( raceial_continent );
etc.
What is the difference between the two approaches; is there any meaningful difference in disk-space between the one multi-colum index and the four single-column indexes? Does it make a difference in what the query-planner will consider?
And, if I define one multi-column BITMAP index, does the order of columns matter?

You may want to read this two-part blog, that answers that exact question, by recognized expert Richard Foote

http://richardfoote.wordpress.com/2010/05/12/concatenated-bitmap-indexes-part-ii-everybodys-got-to-learn-sometime/
As with many things Oracle the answer is 'it depends'.
In short the same considerations apply for a concatenated index whether it is bitmap or b-tree: 1) will the leading column usually be in the predicate and 2) will most or all of the index columns be specified in the queries.
Here are some quotes from part 1
>
Many of the same issues and factors in deciding to create a single, multi-column index vs. several, single column indexes apply to Bitmap indexes as they do with B-Tree indexes, although there are a number of key differences to consider as well.
Another thing to note regarding a concatenated Bitmap index is that the potential number of index entries is a product of distinct combinations of data of the indexed columns.
A concatenated Bitmap index can potentially use less or more space than corresponding single column indexes, it depends on the number of index entries that are derived and the distribution of the data with the table.
>
Here is the lead quote from part 2
>
The issues regarding whether to go for single column indexes vs. concatenated indexes are similar for Bitmap indexes as they are for B-Tree indexes.
It’s generally more efficient to access a concatenated index as it’s only the one index with less processing and less throwaway rowids/rows to contend with. However it’s more flexible to have single column indexes, especially for Bitmap indexes that are kinda designed to be used concurrently, as concatenated indexes are heavily dependant on the leading column being known in queries.

Bitmap index Vs B-Tree index

Hi All,
Could some one please let me know how Bitmap indexes are useful compared to B-Tree indexes on low-cardinality columns ?.
Thanks,
-Kumar.

As Re: why oracle db 9i optimizer can't choose to use the bitmap index? there are a number of issues with bitmap indexes. Your best bet is to read these three articles by Jonathan Lewis.
It does pay us to understand how the optimizer works with bitmap indexes. I posted some Re: Cost-based optimizer behavior to show how indexes on even very low valued columns can be useful in certain circumstances.

IOS 8.1+ Performance Issue

Hello,
I encountered a serious performance bug in Adobe Air iOS application on devices running iOS 8.1 or later. Approximately in 1-2 minutes fps drops to 7 or lower without interacting with the app. This is very noticeable in the app. The app looks like frozen for about 0.5 seconds. The bug doesn't appear on every session.
Devices tested: iPad Mini iOS 8.1.1, iPhone 6 iOS 8.2. iPod Touch 4 iOS 6 is working correctly.
Air SDK versions: 15 and 17 tested.
I can track the bug using Adobe Scout. There is a noticeable spike on frame time 1.16. Framerate drops to 7.0. The App spends much time on function Runtime overhead. Sometimes the top activity is Running AS3 attached to frame or Waiting For Next Frame instead of Runtime overhead.
The bug can be reproduced on an empty application having a one bitmap on stage. Open the app and wait for two minutes and the bug should appear. If not, just close and relaunch the app.

Hi
Id already activated Messages and entered the 6 digit code I was presented with into my iPhone. I can receive txt messages from non iOS users on my iMac and can reply to those messages.
I just can't send a new message from scratch to a non iOS user :-s
