confused about the function of culture
OK I've been using photoshop for a while but it has the function of culture changed? My question is, when I crop a picture, even though I have crops on a very small section, the file remains the same size (pixel dimensions). If an image is 60 m and I have very small crops, it remains 60 M and 5616 X 3200 pixel, for example. I'm a bit confused by the present, I'm sure that when I have cultivated an image before it reduces when I cultures. I hope that I myself make clear...
any help appreciated.

Confused about the extension of the Sprite class
Howdy-
I learn programming with object oriented ActionScript and am confused about the class Sprite and OO in general.
My understanding is that the Sprite class allows you to group a set of objects that you can manipulate all the objects at the same time.
I explored the Open Flash Chart code and note that the main class extends the Sprite class:
Base/public class extends Sprite {}
What this lets you do?
Also, on a related note, how to draw, say, a line once I extended?
Without extend Sprite I could write:
var graphContainer:Sprite = new Sprite();
var newLine:Graphics = graphContainer.graphics;
...
And it works very well. Once I have extend the Sprite class, I'm lost. How can I modify this code so that it still draws a line? I tried:
var newLine:Graphics = this.graphics;
My understanding is that since I extend the Sprite class, I should still be able to call its method chart (or property? I have no idea). But, he screams at me, saying "1046: Type was not found or is not a constant of compilation: graphs.»
A number of things.
First of all, I would not use this approach in your table constructor. Setting the width and height only makes sense if you adjust the width and height of the existing content, and the table (Sprite) does not at this time here. If you want to give the table a 'size', you could do it like this:
public function Chart (width: Number, height: Number) {}
This.Width = width;
This.Height = height;
put in a background invisible to this size:
this.graphics.beginFill (0,0);
this.graphics.drawRect (0,0,width,height);
}There are other ways, including putting in a form or a Sprite of child as a child for the background so that clear will not erase the background of the chart. This way you could have properties for the background in your table class and update the background as a child DisplayObject instance... a few ideas to think to...
Then, after that, your chart should be functional...
Then back in your scenario, you could do this:
import graphics. Table;
Stop()
var myNewChart:Chart = new Chart (300,200)
myNewChart.render ();
addChild (myNewChart) -
Ask questions about the functionality of EA8500 MU-MIMO
Dear Linksys
I bought EA8500, and it arrived today.
I have two questions about the functionality of MU-MIMO of EA8500 AP.
1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?
2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.
This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?
Thank you
Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.

Confused about the notion of VLAN
I'm confused about the VLAN. I thought that the notion of VLAN was this computer on different VLANS were not suppose to be able to communicate with each other.

Confusion about the size of the array in Oracle 11 g
There is confusion about the size of a table. When exporting schema 'CRESTELWOMPRD601', the log file shows:
_____________________________________________________________________________________
. . exported "CRESTELWOMPRD601." "' TBLRSUBSCRIBERFIELDWORK ' lines of 12.62 GB 35568
____________________________________________________________________________________
which may involve the size of the TBLRSUBSCRIBERFIELDWORK table is 12.62 GB.
But when I find the size of the table using the query:
SELECT nom_segment, BYTES / 1024 / 1024 "SIZE (MB)" FROM dba_segments where owner = 'CRESTELWOMPRD601' and nom_segment = 'TBLRSUBSCRIBERFIELDWORK. '
He said that the size is only 9 MB for the TBLRSUBSCRIBERFIELDWORK table.
I hope that my request is clear that there is no clarity on the size of the TBLRSUBSCRIBERFIELDWORK table.
Please get back with the answer to my query
Concerning
Dba_segments indicates the space allocated to the segment while expdp indicates the size of the exported data, so if you had a table with a measure of 1 MB, but no data, dba_segments would 1 MB and expdp would report 0 bytes.

Confusion about the requirements for the 2015 CC software
I currently have Windows 8.0 (64 bit) which is so satisfactory and stable. I have not upgraded to 8.1 Windows because I can't install same normal updates for Windows 8.0 without experiencing freezes system that only restore points can heal. So for now, I would stick with what I have. But the problem is the confusing requirements for various programs within the pile of creative cloud applications:
Premiere Pro: Microsoft Windows 7 Service Pack 1 (64-bit) or Windows 8 (64-bit)
Photoshop: Microsoft Windows 7 with Service Pack 1 or Windows 8.1Illustrator: Microsoft Windows 7 with Service Pack 1, Windows 8 or 8.1 Windows
Dreamweaver: Microsoft Windows 7, Windows 8 or 8.1 Windows
Hearing: Microsoft® Windows® 7 with Service Pack 1 (64-bit), Windows 8 (64-bit) or Windows 8.1 (64-bit)
So what I'm confused about is the fact that Windows 8.0 is not listed for Photoshop, but Windows 7 and Windows 8.1 are. Does this mean Photoshop CC 2015 is not compatible with Windows 8? And that means that Premiere Pro is not compatible with Windows 8.1 since only 7.0 (SP1) and 8.0 are listed, I would have preferred the upgrade of software CC WITHOUT update Windows since I am picky on my installation of Windows 8 stable pipes now solid as a rock. Fortunately, Illustrator, Dreamweaver, and hearing are compatible with all three, it seems.
Can someone clear up the confusion, please?
I think that my hardware is OK for this.
Motherboard: Asus Crosshair Formula V-Z (AMD 990FX)
CPU: AMD FX-6300 Vichera 3.5 GHz
Memory: 16GB Kingston HyperX DDR3 2133 MHz

Confused about the capacity of the HARD drive on my new Equium L350
I'm rather confused (normal state) about the capacity of my hard disk. This is supposed to be 120 GB but... On 'My computer', it shows that I have 23 GB of 55.7 left GB on Vista C and 49.8 54.5 on E of data that is delivered to about 110 GB.
I'm already about 10 GB missing but maybe that is taken up with hidden files. More worrying is that I have so little space on Vista C. Can I save files on the data partition, or is that a no-no? So far, everything I've loaded on it goes into Vista C.
Any help would be appreciated.
Thank youI agree with InvaderZim.
But there should also be another reason why the two partitions of HARD drive are smaller than the whole HARD disk.
I assume you are using the Vista operating system.
Vista uses hidden for some files from recovery partition.
If you check the Disk Manager, and you should see all available on your HARD disk partitions.See you soon

Confused about the new creative cloud
Hi all
Since I read adout the new creative cloud I'm confused about what will happen to my license for Adobe Lightroom. Will they remain still desktop apps as well or I have to pay for an annual license, if I want to use new versions of Lightroom?
I am a casual photographer and I like to use Lighroom for my photos, but I don't think that pay for an annual license because I'm not spending a lot of time, image-editing.
Can someone clarify this for me?
Thank you very much
Lucian
5 Lightroom does not have subscription only, you're fine. There is no sign that it will even happen in the foreseeable future either. It's just the ex-Creative-Suite that all talk.
Target market of Lightroom is different from the Creative Suite/Cloud. CC is a good deal for the majority of its base of users (next door), while the majority signed without major complaints. Lightroom has a huge customer base amateur, and they would be much more difficult to convince us to go subscription only. They would be likely to lose most of customers of Lightroom at the moment, and they are not completely stupid.

Confused about the layout of the table of contents
Hello
I work in FM7 and I go through the manual for help on the table of contents page layout. More precisely what I can't understand is how to group entries in a list generated.
I work in a book with a number of files; I'll have a TOC, LOF and MANY. In the table of contents what I want to do is entered from the Section and chapter group. In other words, I want in my table of contents:
Section xx
Chapter xx
Section
Section
Section
Chapter xx
Section
Section xx
etc.
I also tried to understand the inputs on the reference page to see if I understand the grouping of the way in which they are displayed on the page.
Question - how do I? Do I need to format the entries in the reference page? Or is it another place. (This applies also to my LOF and BATCH)
Advice appreciated.
Carl
Will you put a paragraph of the Section of each chapter title? If so, that is the problem - there should be only one paragraph of Section heading, in the chapter where the section actually starts. Succeeding chapters located in this section should not have a Section title.
That's where you mix and match with the concept of "clustering" and the functioning of an Index.
TOCs of work by selecting the actual paragraph for each specified tag - FM is not "roll up" all paragraphs in the Section title even if they are the same.
If you need to have the text of the title of the Section repeated on each subsequent chapter early, I suggest make you a new paratag, for example "Section Repeater", and then not include this tag in your table of contents, of course. There are other methods to repeat the content, too, as the use of variables and markers, but let's not too confusing thread immediately.

Confusion about the Source of excitement in the bridge SMU-4331 input module
Hello
I had some confusion through the input of the bridge SMU-4331 sheet module.
In the features section of excitement, its current Minimum as 29mA says. What it means. It can only current greater than 29mA delivery!
I think this should me Maximum current specification.
If you look at the table below
350 ohm resistance, the current should be 10V/350 ohm = 28.5mA
but for 1 K ohm, current will me 10V/1Kohm = 10mA, which isn't normal, if you specify current minimum as 29mA.
any thoughts?
Kind regards
Mirash
Hello Mirash,
I'm glad I could help!
As for your other question, the SMU-4330/4331 are inherently peripheral ratiometric. This means that they are designed to detect the level of excitement and range of the ADC to the appropriate scale. In this way, we can compensate for permanent changes in the voltage. One of our engineers wrote a big article really nice area on the subject I would recommend that you take a look at: Sensors of Measuring Bridge-Based with the ratiometric approach
See you soon,.

Question about the functionality of vector mask
Hello everyone, I'm fairly new to Photoshop CS 5 so I apologize if I'm asking the wrong type of questions, here goes:
When you work with vector masks you can:
(1) "the link" or a vector mask with the other images? ' sharing ' a picture (for example) if I did 'A Building' then duplicated, but wanted to change what build a looked like, I have to only change the mask of the source, then the copies would be updated.
(2) move the independent image of the vector mask (it seems that I can only move the vector mask, not the image itself). Or in other words: I can move the image and have the mask to follow, instead of being only able to move the vector mask within the limits of the image?
My application of the question:
I do a top-down 2D layout of a zone of type "Paste". I did to fill the buildings, building A, B, C, etc. and use multiple copies of each building. Ideally, I would like to be able to 'link' or share say building has a vector mask with all other instances of building A (so that when I change the master, they all change to the new form of mask). The second behavior I have trying to find is the ability to move without moving layer where the vector mask is on this layer (since it seems that you can only move where the mask is, which means that even if I could share masks, they all finish by in the same sense of place I have to re - position each hand again.)
Any ideas are appreciated, thank you for reading.

Yes, it's possible, but not with the classic system layer vector mask in Photoshop. Layer masks are part of a layer and not the layers themselves, so that they can be converted into a reusable object.
The solution is to avoid vector layer masks and use a clipping/layer instead mask. A clipping/layer mask CAN be converted into a smart object that is reusable, and when you change one, all the other instances are also changing.
The second part of the solution is to convert the layers contained both the clipping/layer to a smart object mask. Then the batch group. By the way, if your buildings are made up of several elements simply to include these additional elements in the clipping group. Another advantage is that each of the elements may still have its own normal layer mask. Win win situation. And layer effects can be applied to layers/clipping masks, once again what is impossible for layer masks. It also opens the doors to a much less destructive workflow.
(2) move the independent image of the vector mask (it seems that I can only move the vector mask, not the image itself). Or in other words: I can move the image and have the mask to follow, instead of being only able to move the vector mask within the limits of the image?
This is also solved with the use of layers/clipping masks - the content and the mask can be moved independently in regular layers. Another advantage is that the two can also be transformed individually.

Any ideas are appreciated, thank you for reading.
So here's my solution. I made a sample with two buildings, the view from above which could be reused as desired:
(1) first of all create groups for each building and place the content to those. Then trace layer vector shapes on the content. Set the transparency for layers of mask to a reasonable of opacity for masking easier.
(2) put the vector shape under the layer of content for each building. Then, for (1) and (2),
, click on the border between the content and the shape layer. ( BTW, the layer of Photoline system is much more logical and easier to use for this type of work. Layer masks behave like regular diapers. Layers, groups, masks, layers of external file and so forth can be practically cloned and instantiated as smart objects, but the main object is editable in the context, and all the other instances updated in real time. So, it is more convenient. At least this is my experience.
I hope this has been helpful! Now go build your cities. :-)
PS: I thought: isn't Illustrator or InDesign is a much more logical choice for this type of work where you need access to reusable blocks of content? It would also be a more efficient workflow and faster - Photoshop is not really designed for this type of work. Illustrator and InDesign provide potentially out of better quality. You can also divide your work into the pages and so on. Here again, you would probably lose the flexibility of smart objects.
