BLOB, the Image dimensions

Similar Questions

• load the image dimensions

  Hello
  
  I have a script where I load and scale of different images in a single clip, but it is not working properly. The dimensions seem to "keep in memory" for each new image I load gets scaled according to the first value of the scale. The scaling of value remains the same until I load a larger image, then it is changed, but remains at the scale of the enlarged image.
  
  Any ideas on what is the problem? I enclose a sample of my code to this message.
  
  Thank you

  I recently had a bit of a similar problem. The solution was at the beginning of the code onLoadInit 'Reset' the x and can grow up to 100, then did my scaling.

• How to display a column with a representation of the image color in Windows Explorer on Windows 7?

  OK, here's my situation...

  I have a directory with 300 + JPG images in it; I'm hoping to use some (if not all) of these images for a project.

  However, the project has very specific requirements for the image dimensions, resolution, and a representation of the colors; So I need to evaluate the supplied images to validate if they are all in line with these requirements.

  If I right click on an individual image and choose Properties - then click on details, I can see the image information such as:

  • Dimensions,
  • horizontal resolution,
  • vertical resolution, and
  • color representation.

  ... which would be perfect if I had only 1 or 2 images to cross; but with more than 300 images, it becomes cumbersome.

  So: I put the "Détails" view folder and added columns for dimensions, horizontal and vertical resolution resolution.

  This helps my cause, because I can then sort the directory... and quickly see if the images are too small, too big, or unacceptable resolution.

  However, I have not found a way to add a column for the representation of colors.

  Is it possible to add a column for the representation of colors?

  Hello

  Unfortunately there is no other option to define the representation of colors in Windows Explorer. If you want to provide feedback about it, then check out the link:

• the easier way to resize the image

  
  Hello
  What is the best way to resize images? I searched the forum and search engines, only I found things was custome tags or components.
  
  I don't have the part to know where I can use tags custome.
  
  Can someone help me with this?
  
  Thanks in advance!

  Some time ago I was looking for the same thing but could not find any solution that does not involve a component or a custom tag...
  I ended up going with a custom tag called 'Jpegresize '. It works very well and is easy to implement and use.

• Cannot show the dimensions of the image on a Mac?

  Hello

  I know in the 'Pictures' folder, you can select "Show view options" and then "view info point" and it will show dimensions photo... but it is not possible in a different directory, not to mention that the pictures folder?

  I photograph weddings for a living, and I'm fairly new to mac. Naturally, all my images are stored on external drives... I don't see the dimensions of the image? It seems that I have to open each image individually within the preview, and then press CTRL + I to see! Please tell me I'm wrong.

  You can right-click (command-click a button or the trackpads) on the image file and select information.

  The title of the chapter more information, one of the entries is dimensions

  

  Alternatively, if you set the display of the viewfinder to the list, is one of the optional columns to Dimensions. Command-click on the column headers to add or remove columns.

• DisplayImageFile() does not change the dimensions of the image control

  Hello

  I put in an image with DisplayImageFile() control image + assigning to the attribute of control ATTR_FIT_MODE = VAL_SIZE_TO_IMAGE. The image size is larger, then the size of the control and I want the control to resize to the size of the image.

  It works fine except when I ask the dimensions of the control with GetCtrlAttribute (panel, control, ATTR_HEIGHT, & height), I get the original size (before calling DisplayImageFile())...

  It seems I missed something basic...

  Environment: LAB Windows CVI 2012, Windows 7

  Thanks in advance

  I don't know if you still experience this problem or not, but I came across this discussion now and wanted to point out that this could happen if your picture controls if it is covered by another control or is it hidden altogether (and there might be other similar situations that I can't think of right now).

  When this happens, the CVI runtime can pull the image directly on the image. Instead, he plans an asynchronous action that will redraw this section of the Panel from the back to the front (if it's just overlapped, not hidden). It is only in the later action that the image is applied to the control, and it is only then that the control is resized to fit the image. This may seem immediate to the casual observer, but, because it is asynchronous, you can't try to get new size immediately after calling DisplayImageFile, because the image is not yet in control at that moment.

  Ironically, this occurs only if the control has already been set to the image size at the time you call DisplayImageFile. If this isn't the case, then the new size is applied when you later change the mode made programmatically. Whereas if the adjustment mode has been already updated the image size, trying to programmatically set the same value of the image size has no effect and nothing happens then.

  If this is what is happening, one way around this would be to call ProcessDrawEvents or ProcessSystemEvents immediately after the call to DisplayImageFile. Unless the control or Panel has been hidden way explicit, which will require the drawing action will take place at this time, and you should then be able to get the new size of control at any time after that.

• How to retrieve the image BLOB from database and display the image in rtf file using the Oracle XML Desktop 5.6.2 publication server?

  Hi all

  Here I have the image BLOB in the database files,

  I want to show the image to PDF using file to rtf using Oracle Xml Desktop Publisher,

  Hi all

  I found the solution for reading Image BLOB of data base & display in Pdf format.

  (1) read the image from DB.2) and then copy the picture using IO. UtilsCopy method to copy the picture

  (3) then encode with base64 converter then you will get the tag XML with Base64 as string then placed in your XML Code & preview the output, you will find the image

  Photo = (BlobDomain) currentRow.getAttribute ("Image");

  ByteArrayOutputStream OutputStream = new ByteArrayOutputStream();

  	Byte [] imageByte;
  	Byte [] b = null;
  	try {}
  	IOUtils.copy (photo.getInputStream (), outputStream);
  	BS = outputStream.toByteArray ();
  	outputStream.flush ();
  	System.out.println("==="+BS.) Length);
  	Encoded byte [] is Base64.encodeBase64 (bs).;
  	encodedString = new String (encoded);

• APEX 5.0. With the image stored in a BLOB gives ORA-06502.

  Hello

  I want to create an interactive report - computer desk with an image that is stored in a BLOB but it a: returnes ORA-06502: PL/SQL: digital or value error: character of number conversion error.

  I created a test with only the image report (charged - which is a BLOB) and an ID (PK - one number from a sequence)

  SELECT ID, invoice of foto

  I tried with and without a formatmask for the ' 999999999999999 ID' and the Type of plain text, because it seems not to be a better choice...

  For the Type 'pay' is 'View Image' and the 'Table name' and 'BLOB column' are defined. 'Primary Key column 1' set ID 'column of Type mime"points to a field that contains" image/jpeg", as the stored image is a photo in format jpg.

  The image from a Forms application displays OK.

  DB is a 11.2.0.4 on Linux 6.6 and APEX is 5.0

  What did I miss?

  Thank you

  As described in the documentation, the report query selects the length of the BLOB, not the column itself column:

• How to download all the images in the folder to the column of type BLOB (problem of area to create BLOB)

  Hello

  I use JDeveloper 11.1.2.3 version, I need to download all the images in my local folder to the database at a time table. The problem I face is to create BLOBDomain for each of them?

  Best regards,

  Julien

  If you can access the files, that only works if they are on the server, you can read the file and create the domain of the BLOB in the file directly. The technique is the same as in the blob. Only difference is that you pass the file to the method and open the input stream of the file instead of the UploadedFile.

• I did my own art of header for the toolbar and the dimensions and size of the file are correct, but the image appears badly in the area. Why?

  I used photoshop to make my theme header with 3000 pixels wide and 200 from the top. In addition, the file is less than 300 KB. But after that I downloaded it, the picture in these dimensions is amplified. I do not get the image I had intended. Why is this? See picture attached example.

  The support module is here: https://discourse.mozilla-community.org/c/add-ons

  Looks like this monitor is like 1750 pixels wide, give or take.

  The width of the whole image will not be displayed unless you have a display of 3000 pixels wide, and it is " pinned with the upper right of the image. Only, as a large part of the width will be shown that there is the width to display the image.

• How to download the image of the BLOB, inline in new browser tab or window

  APEX V4.2.3

  I have an interactive relationship with a column of type blob download which is the inline value.  When I click on the link 'Download' the image automatically appears in the same window as the application of the APEX.  How do I download the image in a new tab in the browser?  I need to shake "target ="_blank"' somewhere but I don't know where that link structure is hidden."

  Here is the code for my download section in the interactive report.

  Select

  (b) If an is1700x1400px of the image to crop px 1700 x 1700

  After the automated process that each photo should be sized to it's larger size of the horizontal or vertical dimension.

  I am I clear enough?

  Is this possible via shares or any other automatic work?

  You have to use "crop" or you can use "canvas size"? It is easily achievable with a little script. Something like that

  http://pastebin.com/r0EtBj1U

  Copy the contents and paste it into a document with a text editor. Save the document as "MaxCanvas.jsx" and then run via "File-> Scripts" in Photoshop; an action or "whatever." Works like a charm, but I have only tested in Photoshop CC on Maverics.

• How can I unlock the dimensions of the image

  Somehow my pixel dimensions and the dimensions of the document were being blocked and when I try to crop a cropped image dimensions remain in the same proportions of width to the size as the original. There are few symbols and brackets to the right of pixels and inches.  I don't know how to remove these.  I use an archaic version of the Photoshop Elements - version 2.0 on a Mac running 10.4.11.

  

  As far as I remember, your crop tool has its own small boxes for sizes above in the box options when you use it.  Uncheck THOSE (there is even a [Clear] button) to get rid of the lock proportions there.
