Images dissapearing when scrolling TileList.

Hello,
In the AIR application I am working on, I need to load a large number of images to a TileList on the clients computer. Since they can't be embedded, they were taking a long time to load since each image could be 3-4mb+. In an attempt to reduce the load time (initially and when reloading when scrolling) when the user selected a directory, I would load each image using a Loader and store a scaled down Bitmap of it in an Array. I bound the source property of the Image in the ItemRenderer to the Bitmap in the Array.
This works really well and the images load faster however.. When I scroll and an image goes off the screen and I scroll back to it the tile is blank. Checking the debugger I see that as soon as the tile goes off the screen the BitmapData property of the Bitmap in the array becomes null.
Any ideas on what might be causing this? I can post the code if it would help.
I'm not limited to loading the images this way. I had just seen something similar and was trying to adapt it. If anyone has any other methods or controls that may work better please share!
Thank you in advance for any help.

I have the same problem.

Scrollview only releasing image data when scrolled out of bounds

Hi all,
I cannot understand why my memory isn't released.
On my iPhone program I have a tableview with an image in each cell. When the images are loaded the I can see a thread in Instruments with ObjectAlloc, that calls CALayerPrepareCommit about 10 times -> CGContextDrawImage->some more stuff->ripc_AcquireImage->more stuff ->imgdatalock. I assume this is where the OS actually draws the Image on the screen. But the memory is never released! Only when I scroll the tableview out of bound is the memory released. Visually the tableview is the same and the images are still there after the scrolling. This is a lot of memory and I need to know why it isn't released.
I set the image in the tableview here:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = self.showDisclosureIndicators ? UITableViewCellAccessoryDisclosureIndicator : UITableViewCellAccessoryNone;
//Clear previous content
NSArray *subviews = cell.contentView.subviews;
for (UIView *subview in subviews)
[subview removeFromSuperview];
//Set Image
[cell.contentView addSubview:[thumbnails objectAtIndex:indexPath.row]];
return cell;
thumbnails is an array of views:
while (thumbnailsRemaining && getThumbnails) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
UIView *containerView = [thumbnails objectAtIndex:nextThumbnail];
UIImageView *imageView = [[containerView subviews] objectAtIndex:0];
NSInvocationOperation* imageOp = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(getImageForImageView:) object:imageView];
[imageQueue addOperation:imageOp];
[imageOp release];
[imageQueue waitUntilAllOperationsAreFinished];
nextThumbnail++;
[pool drain];
and each image is loaded here:
- (void) getImageForImageView:(UIImageView *)imageView {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
UIImage *image = [UIImage imageWithData:imageData];
[imageView setImage:image];
thumbnailsRemaining--;
[pool drain];
I also have a scrollview with images and behaving exactly in the same way when scrolling out of bounds.
I am really lost, so any help is appreciated.

When a cell is scrolled out of the visible area, UITableView normally adds it to the reusable cell queue, so that's why you aren't seeing that memory released. I think the queued cells might get released under low memory conditions. You might want to try Hardware->Simulate Memory Warning on the Simulator.
In any case, see if this link is helpful: [http://idevkit.com/forums/tutorials-code-samples-sdk/2-dynamic-content-loading -uitableview.html].

Image dissapears when cropping

When using the crop tool, and I expand the cropped area outside the original image, the image dissapears and the area turns white. How do I turn what ever "feature" this is off?

When moving the crop beyond the image boundries, the added canvas is shown with the background colour. To prevent this from happening, double click the background layer to make it a normal layer. They additional canvas will then appear as transparent.

Keeping Animation States on Item renderers when scrolling TileList

Hey all,
 so I have a simple custom item renderer (CustomRenderer.as) which has a FlexShape that gets tweened by TweenLite depending on the percent value in the data value object (CustomRendererData.as). So in the example below I have 8 items
| DATA ITEM 1 | DATA ITEM 2 | DATA ITEM 3 | DATA ITEM 4 |
| DATA ITEM 5 | DATA ITEM 6 | DATA ITEM 7 | DATA ITEM 8 |
The issue I run into is when i scroll (vertically) the FlexShape starts to Tween from the previous data values.
For example DATA ITEM 1 is has tweened upto 80% and DATA ITEM 2 has tweened up to 20% . DATAITEM 2 appears to be at 80% first and then Tweens to 20% . You can try the sample below. Once you clicck on the Load Data button the animations will begin. When you use the scroll bar you can see the animation states being swapped to the previous data renderer items and then resuming their orignal values

The problem with renderers is that they're recycled, so probably that's why your List keep losing the animation states.

Jeditorpane/html - images disappear when scrolling

The title says it-
I've had this issue with JEditorPanes in my own code and also with the Java Help viewer. I'm using 1.4.1_01.
I don't have a lot of images or any very large ones. My pages are quite standard, and very simple- just text and greatly reduced screenshots.
When I scroll up and down in the component, however, images either completely disappear or part of them disappears. Reloading the page fixes it. Definately a repaint issue of some sort. But, in the case of Java Help, I don't have access to the JEditorPane to hack in any kind of fix.
Whats the deal here? I can't find any bug postings about this one but it certainly seems to be a major bug.
Thanks

I'm glad to hear someone else is having the problem. Any ideas on a work around?
There has to be some work around. For example, I'm using IDEA for my IDE and it is running under 1.4.1_01- clearly they have used Java Help but their help view isn't having the same problem mine is. I hope I find a solution soon. This is an absolute show stopper. I can't deploy something that is clearly broken.
It is next to impossible that this is a user error- I haven't even written any code! It is all Java Help's code. I've even tried to turn off all the fancy drawing that is part of Swing, and turned off all hardware acceleration in Windows.

WHAT IN THE NAME OF GREAT CAESAR'S GHOST IS GOING ON HERE??
The background image on the second page SHIFTS over a few
pixels simply because I hard returned several times. The completion
of my entire site has been resting on this simple little headache.
Please help....

>>whenever I hard return several times
Stop doing that. There is never a valid reason in a properly
designed/constructed page to add empty paragraphs.
Probably... after adding content, even empty paragraphs, the
display window
in DW design view drops a vertical scroll bar thereby
changing the
horizontal location of the page's middle. Your bg image is
aligned middle so
it moves.
IOW there is no problem. Just build your page.

Photos in album are only a hash-marked outline the image only shows when scrolling how can I see the image and open the photo?

Photos in iPhoto album are only a hash-marked outline the image only shows when scrolling how can I see the image and open the photo?

Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
OT

In my iPhoto library, only some images appear as thumbnails. The rest are blank but appear briefly when scrolling through or properly when double clicked. Any ideas?

In my iPhoto library, only some images appear as thumbnails. The rest are blank but appear briefly when scrolling through or properly when double clicked. Any ideas?

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Flash content distorts when scrolling and switching tabs.. since FF 13.0.1..

Before describing the issue
Please note from the System Details pane to this post that I have the latest flash, etc.
And Windows updates,are up to date.
==================================================
Issue: Scrolling distorts flash player window (Youtube, hulu, etc.)
Since: FF 13.0.1 update in June. (I posted on the issue under "badly scrambled images".)
Problem is still there with FF 14.0.1
This distortion happens:
# even with just starting the browser (so no bloated cache)
# even with just only one or two tabs open.
And since last week's update to FF 14.01, I have also detected:
Switching to the the tab with flash content will "imprint" the image from the my previous tab on to the flash player. I have to scroll or refresh to get the flash player to show its content.
FYI, none of these flash player problems occur with IE9.
The advise from a regular contributor was to turn off hardware acceleration, but these did not solve this issue.:(
Solutions suggesting disabling all the plugins etc. have not solved the problem either.
So if you can tell me some other way to solve this, I will appreciate it.
Thanks.

Sorry, it took me a while to give feedback for the suggestions you have given here.
(Please refer to sidebar on the original post for system details.)
I have reset the profile and updated the Nvidia driver. The version of FF is 14.0.1. But it still scrambles the pictures.
On top of scrambling the flash content when scrolling, it has additional problems:
As you can see from the attached image, another tab's content is showing on the youtube flash player. This happens when I have paused the video even for a short time.
I have a suspicion that the combination of Flash and Firefox does some weird things to graphic processing and memory.
(I realize that IE implements Flash differently, but they seem to have this right.)
I might just have to say goodbye to Firefox for a while.
Thanks.

Does anyone know how to save / preserve image maps when updating graphics?

Hello all,
I'm currently working on a RH7 HTML project, which I've designed to be used in support of a software application.
Some of the application's dialogue boxes have quite complex multi-tabbed GUIs, so when it comes to describing their functionality, you often end up with a long list below the graphic image. What this means of course, is that the user is forever scrolling up and down to make reference between the GUI and the explanatory text.
I hit upon an idea I'd used previously, whereby I created popups to multiple image map hotspots. It works like a dream and the client and users really like the concept - but there's a snag (apparently).
Because the application is still in development. some of those GUIs are (and will continue to) change. No problem with that either - until I try and insert the updated graphic. Poof !! All my hotspots disappear . . .
Surely I'm not alone in trying this approach and there must be some way of preserving the hotspots?
Any suggestions?
Bob (in a UK time zone)

Hi there
It sounds like you are using the standard methods of inserting an image. Don't do that!
All you need to do in these cases is to use Windows Explorer to save the updated image using the same file name and replacing the former image. When you do this your other data will remain intact. If the new image is a different size, just right-click it inside the RoboHelp HTML editor and choose Reset Size. You also may need to tweak your hotspots if things shifted some.
Cheers... Rick

Numbers crashes when scrolling

Since updating to IOS 8, including all subsequent updates released for IOS 8, Numbers has exhibited crashing when scrolling horizontally or vertically when the spreadsheet exceeds the screen boundaries. I have erased Numbers from the iPad Air (symptoms seem to cover full iPad family) and reloaded from iTunes. This does not resolve the crash. The crash seems to occur when scrolling in a flipping finger motion, vertically or horizontally. The faster the finger flip the more likely and sooner Numbers will crash. Scrolling horizontally or vertically in a slower motion seems to delay the eventual crash, but does not eliminate the problem. This tendency for crashing Numbers renders this software useless. I sincerely hope that the Apple software team will review this problem. It has been sited in a number of other support threads.

I was having similar problems in Lion when with windowserver crashes when switching between windows or scrolling in Numbers or switching to iPhoto from other apps. I upgraded to ML because I was told this may fix the issue. Now i can't keen open iPhoto. I have Pram restarted and iPhoto opens but as soon as an image is selected I have another window server crash. Pre ML install I did a clean install of Lion and it made no difference.
Hopefully no one here told you that. A common theme is people blaming all problem on Lion or Mountain Lion, whatever operating system was just released and telling people with obvious hardware problems that they need to wait for a "bug fix". Updates come and updates go - taking warranties with them - but no fix ever happens.
There is a small possibility that the "Soundflower" kernel extension is giving you problems. It is very unusual to see a kernel panic without Soundflower being listed. If you remove that and still have panics, then it is definitely a hardware problem.

Brief blurriness when scrolling in scanned PDF

Hello all. I frequently find that when scrolling through pages in a scanned PDF, it takes a second or two for the page images to resolve; that is, they appear blurry at first and only a second or two later do they resolve into clear page images. The PDFs are about 50 pages long, in color, and were scanned at 300 dpi with moderate compression (they are about 75mb each). Is there any way to fix this? Thanks.

Could you please share the document with us?

30EA3: Monitor sessions grid freezes when scrolling lo last session

Hi,
I've found an issue with the Monitor Sessions grid.
Steps to reproduce the problem (scenario I have tested an reproduced the issue)
1. Open monitor sessions window
2. Order the grid by "OS User" column (In this scenario, my "OS user" is the last one alphabetically)
3. Scroll down in the grid, until reach the last record (as mentioned above, the last session is the same session that is monitoring since my user is the last one alphabetically)
Then SQL Developer freezes, processor time and memory start to increase; and also, seems that SQL Developer window is trying to get the focus, so it doesnt let me navigate freely to other applications, is even difficult to open task manager to kill the process since SQL developer window in the background keeps getting the focus of mouse and keyboard.
Thanks and regards
Ramiro Teran

Hi Raghu,
1. As I mentioned, the scenario I tested was the "Monitor Sessions" grid, at first I only tested scrolling down to the last record, in the master grid using the mouse wheel, but now I have also tried crtl+end, and it also happens
2. 184 records in parent grid (Sessions)
3. The child grid is the "Active SQL" tab (first tab) of the detail of the session.
4. Yes, there was a cell in master selected, but when scrolling down and reaching the bottom (or doing ctrl+end), then the last cell is selected automatically, and SQLDeveloper freezes.
As mentioned in my first post, the SQLDeveloper not only freezes, but doesn't let you navigate to other windows (every couple of seconds SQLDeveloper gets focus on its window, even though is frozen)
I have took an screenshot showing the issue, even though, maybe you can't appreciate the issue on an image, since the image only shows the last record of the monitor sessions grid selected, (at that time SQL developer is hanged, and doens't respond to clics or keyboard comands). Also it shows the Task Manager showing increased memory and CPU ussage from the SQL Developer process. If you're interested in this screenshot, let me know where/how to upload it
Thanks and Regards
Ramiro
