Increasing size of image?

i sometimes need to add files to an image file ive made, the .dmg, and i was wondering if theres anyway to increase the size of the dmg as i need to add more to it or do i have to make a new bigger image file?

Hi Andre
To resize a diskimage open Terminal and use this syntax
hdiutil resize -size 80m nameof.dmg
This increases the size of nameof.dmg to 80 Mbytes
Make sure your reference path to the diskimage is correct.
For further details in terminal type
man hdiutil

Saving images with quality 12 increases size. Why?

A minutely modifyed image saved with quality of 10 maintained its original size (more or less), but saving with a quality of 12 increases size.
I would like to know why?
I'd appreciate your comments.

Because that's how .jpg works. Sizes of less than 10 usually compress your files somewhat, lower numbers resulting in smaller file sizes and more compression, with a corresponding loss of quality. Sizes greater than 10 also use the .jpg compression algorithm, but they choose less compression, and so two pixels that may have been compressed together at compression 10 may now be separated at compression 11 or 12, resulting in a larger file. (But that doesn't imply an increase in the quality, even at 12 there is still a slight decrease in quality in that the .jpg saved version still doesn't exactly represent what you saw on the screen)
The amount of modification to the photo doesn't really matter in how much the space the .jpg compression takes up.

HT1198 I shared disk space and my iPhoto library as described in this article. When creating the disk image, I thought I had set aside enough space to allow for growth (50G). I'm running out of space. What's the best way to increase the disk image size?

Done. Thank you, Allan.
The sparse image article you sent a link to needs a little updating (or there's some variability in prompts (no password was required) with my OS and/or Disk Utility version), but it worked.
Phew! It would have been much more time consuming to use Time Machine to recover all my photos after repartitioning the drive.

Size of image is getting increased

Hi
I have cross compiled BDB using m68k-elf toolchain.
I'm using motorola coldfire processor with uClinux for our development purpose. Now I need to include BDB into uClinux and flash it into our processor. The flash we are using is 4mb. The image I have built (without BDB) was around 1.3MB. But if I include BDB libraries and make the image, the size of image is 11MB. How can I come out of this problem
After i cross compiled BDB, I have taken the library files created ( libdb.a, libdb-4.5.a ) into romfs/lib and binary files (db_archive, db_dump,db_load.........) into romfs/bin of uClinux distribution and made the image.
I fell that it is not the right process but dont have any idea how to go with. Image size should be less. Can anyone help me
Thanks inadvance

Hi Elizabeth,
Another possible cause of your problem is that you are building static libraries. Each time you link against a static library (in this case the Berkeley DB library for each utility), the footprint of the library is added to the size of the application being built.
You should probably configure Berkeley DB with the "--enable-shared --disable-static" flags. That will generate libdb*.so files not libdb*.a files, and the resulting utilities should be significantly smaller.

Low File Size/Great Image Quality: H.264, AAC

1. I created a slideshow in iPhoto, exported it to a QT movie file. The properties of it is as follows:
Exibit A:
Dimensions: 720x480
Format: MPEG-4 Video, AAC, Stereo, 44.100kHz
FPS: 30
Data Rate: 7277.87 kbits/sec
Channel Count: 2
Duration: 02'46
Size: 143.58MB
2. I pulled a QT Movie file from the web with the following properties:
Exibit B:
Dimensions: 480x360
Format: AAC, H.264, Stereo (LR), 48.000kHz
FPS: 28.79
Channel Count: 2
Duration: 01'22
Data Rate: 868.14 kbits/sec
Size: 8.5MB
3. I tried to see if I could compress my movie and keep the quality as comparible to Exibit B. Here's what I ended up with:
Exibit C:
Dimensions: 720x480
Format: AAC, H.264, Stereo (LR), 44.100kHz
FPS: 30
Data Rate: 4826.73 kbits/sec
Channel Count: 2
Duration: 02'46
Size: 95.22MB
4. I tried again. This time creating the same dimension as Exibit B. Here what I got:
Exibit D:
Dimensions: 480x360
Format: AAC, H.264, Stereo (LR), 44.100 kHz
FPS: 30
Data Rate: 2577.17 kbits/sec
Channel Count: 2
Duration: 02'46
Size: 51MB
How can I create a very low size and image quality as Exibit B?
I have QTPro. Do I need something else?
Thanks.

Update:
Well playing all exibits on the Windows workstation worked just fine after the update. I now has QT7.
Next...I've exported Exibit A down to 8MB (Exitbit F)by recommendations from Capt. QTKirk. Here are the properties:
Exibit F:
Format: AAC, Stereo (LR), 32.000kHz, H.264, 720x480, Millions
FPS: 15
Data Size: 8.5MB
Data Rate: 429.79kbits/sec
Overall Quality:
Video: Fair at 720x480; much better at 486x324; overall choppy transitions as well
Audio: Fair -close to mono.
Anyone else have any suggestions?
How and what are others using to get the audio/video quality as crisp and sharp as what's shown in the QT Movie Trailer site?

Reducing size of datatype involved in index fails where as increasing size work

This question is related to my question in SO Database
events that will cause deletion of index
For example if i create a table like
CREATE TABLE dbo.Customers (ID INT IDENTITY(1,1) PRIMARY KEY CLUSTERED, CustomerName NVARCHAR(200));
CREATE INDEX IX_CustomerName ON dbo.Customers(CustomerName);
And then try to change column datatype like shown below to 230 from 200.
alter table Customers
alter column CustomerName nvarchar(230) null
The above alter command runs successfully and index IX_CustomerName is not dropped.
But if i try to reduce the size of column to 150 from 200 then it shows error.
alter table Customers
alter column CustomerName nvarchar(150) null
I get error like
Msg 5074, Level 16, State 1, Line 1
The index 'IX_CustomerName' is dependent on column 'CustomerName'.
Msg 4922, Level 16, State 9, Line 1
ALTER TABLE ALTER COLUMN CustomerName failed because one or more objects access this column.
So reducing the size(data may loss) of a column does not work if index is present on a column where as if the index not present then above
query works successfully. So why does it does not allow reducing the column when index present where as increasing size does not show any problem and works?

Hello,
Indeed, a little bit strange even because in BOL it's documented for a different behaviour, see
ALTER TABLE (Transact-SQL) => Remarks =>
"Changing the Size of a Column
You can change the length, precision, or scale of a column by specifying a new size for the column data type in the ALTER COLUMN clause. If data exists in the column, the new size cannot be smaller than the maximum size of the data. Also, the column cannot
be defined in an index, unless the column is a varchar, nvarchar, or varbinary data type and the index is not the result of a PRIMARY KEY constraint. See example P."

How to reduce size of image while uploading it in livecycle pdf.

Hi,
I have created a pdf with Image field using live cycle designer.
I have selected "Sizing: Scale Image to fit Rectangle".
Now the problem is the pdf which i have created is 1.5MB and if i import or upload a 2.5MB image in image field then the size of pdf becomes 6MB.
I have around 20 image fields in my pdf report , so if people keep uploading high resolution images in the pdf then the pdf becomes more then 15MB, slow and unmanagable.
Is there any way by which even if I upload a 5MB image the it should automatically reduce image size?
As the users does not bother to reduce the size of image they just upload high resolution and large size image in pdf.
Please tell me the way through which i can reduce the image size automatically while uploading.
Regards,
Kartik Shrivastava

How to increase size of fonts in Menu bar and in Safari toolbar?

How to increase size of fonts in Menu bar and in Safari toolbar? Munu bar and Safari toolbar fonts too small on a 24" iMac screen.
Thanks in advance !

If you want to change the size of the font of a TextEdit text document, you do it in the preferences. Alternatively, if you want control over the size of the fonts, make it a Rich Text document, and then you can change the font size. You can either use the Larger or Smaller options, or Show Fonts to choose a size. You can elect to have new documents be Rich Text in the preferences as well.

Changing the size of images displayed when a thumbnail is clicked

In an Aperture gallery, how do I change the size an image is displayed when a thumbnail is clicked. There are sliders for changing the size of the thumbnail; I can't find an adjustment anywhere for the size an image is displayed when the curved arrow in the upper left hand corner is clicked.
Help!
--Kenoli

Hi Kenoli,
In an Aperture gallery, how do I change the size an image is displayed when a thumbnail is clicked.
Do you mean "double-clicked"? In "Browser" mode, when I click on a photo, nothing changes. However, when I double-click on a photo, it switches to "Viewer" mode.
However, I'm missing the curved arrow that you mention. I can't find any photos with a curved arrow over them in any mode. In fact, the only overlays are the badges in the lower right.
Can you be a little more specific about exactly what mode you are in?

How can i reduce the size of Images in MIDlet

Hi all,
How can i reduce the size of Images in Form,bcoz they are covering lots of spaces in form due to that other items are not displaying in specific order.

Better you can use Canvas class and using drawImage() function you can show the image. Before that you have to Get the maximum size of your phone screen using the following:
x = (width/2) - (image.getWidth()/2);
y = (height/2) - (image.getHeight()/2);

Adding or increasing size of redo logs

Hi,
I launched health Chack of TOAD on my Database and I had :
! "Checkpoint not complete" errors: 1744
! (consider adding or increasing size of redo logs to resolve this)
My question is how to
1- add a logfile ?
2-increase a logfile ?
Many thanks.

The size is set when you create the redo logs you can not adjust this size without going through a lot of hoops. One method of increasing the size is described in metalink note: 1035935.6
Basically you have to create new log groups of the size you want like
SQL>alter database add logfile group 4 '/opt/oracle/data/redo4/log4a.dbf' size 10M;
Do this for as many new groups as you want with the size you want.
Then when the original groups are INACTIVE which can be seen in the v$log table, drop those groups.
alter database drop logfile group 1;
But read the entire note before you do anything.

Safari always loads small window size have to always increase size pressAA several times. How can I have it bigger by default ?

Safari always loads small window size It leaves a wide margin on both side of the window. I have to always increase size press AA several times. How can I have it bigger by default ?
Changing the font size does not work. Many Thanks

Hi Bee
This is not what I mean. I'm not a new user of computers. Even when the window fills the screen. There are wide boarders either side, have to press the AA serveral times to increase web page (in the tool bar top left) so that the web page fits the window.
