Creating previews from image files and images

static Image alloc(char* path_or_url = 0)

Create a preview of a file. Image objects must be deleted again with image::release! Paths can be complete system paths (OS X) or URLs. The internal representation of the image is first set up when the image is actually required.

Name Type Default Description
Return Image   Preview of an image file or allocating a new empty image
path_or_url String or char* - Complete data file or URL to an image file. URLs only supported under Mac OS X.

If the parameter is missing (since version 2.0 R634 the parameter is allowed to be empty too), an empty image is allocated.
#include "internal/types.h"
img = image::alloc (path);

Get the preview of a template from the current database and save it onto the desktop. 

#include "internal/types.h"
#include "internal/text.h"

int main ()
{
    Query 	qu 		= sql::query (sql::dbconnection ());
    Image	img		= 0;

    /// Init
    if (!qu)
    {
        showmessage ("No database connction");
        return 0;
    }

    img	= image::alloc ();

    // Retreive image
    query::send (qu, "select preview from pageitems where ID = 15"); 
    query::output (qu, kImage, img);
    if (!query::exec(qu))
    {
        query::close (qu);
        image::release (img);
        return 0;
    }
    while (query::fetch (qu)) {}
    query::close (qu);

    // Save image file
    wlog ("", "Size of image : %d\n", image::bytes (img));
    image::save (img, "$DESKTOP/aaa/pageitem15.jpg", 1);
    image::release (img);

    return 0;
}

You can load images from the internet directly. Attention : If you don't want an embedded image, you have to dump your image to a file using image::save and import the file using frame::image instead of frame::embed_image. 

#include "internal/text.h"
#include "internal/types.h"

int main ()
{
    char		imgFile	[255];
    int 		res;
    char		dp		[2000];
    Image		img		= 0;

    document::folder (dp);
    strcpy (imgFile, "http://www.hi13.de/Auto.JPG");
    img = image::alloc (imgFile);

    res = frame::embed_image (gFrame, img, kPlaceTopLeft, 0.0);

    if (res == 0) 	wlog ("", "Embedding '%s' successfully finished\n", imgFile);
    else			wlog ("", "Embedding '%s' done with error %d\n", imgFile, res);
    image::release (img);

    return 0;
}

image::release

static Image preview(
  Image org,
  int size = 0,
  int resolution = 72,
  int color_depth = 24,
  char* format= "JPEG")

Mac only Create a preview of an image. Under Windows, a copy of the image is returned. The call creates a new image from the original. If the original is not yet loaded, it will be automatically loaded. Images created by preview must be deleted again with image::release.

Color depth cannot set on every image format (PICT, ...), in this cases it will be ignored.

Previews created with support from QuickTime, that is installed by default on Macintosh platforms only.

Create a bar code image from a string. The image is created as an embedded Postscript image, no additional files are created.

Attention: InDesign changes directly embedded Posctscript images while exporting an re-importing the document using IDML:

  1. Embedded Postscript images are converted into pixel images automatically. And, in addition, the new image is embedded into a new frame. Only the new created frame is inserted (as a sub-frame) into the original frame.
  2. Pixel images may have different sizes than their originals.
  3. Pixel images will get an (unknown) resolution.
If you wish to use IDML-veersions of your documents, you have created the barcodes IDML-save. See parameters filetype and filepath how to do this.

The function is a nice to have and is NOT subject of any support by WERK II!

Please check the codes for validity before using them. Wrong codes can cause InDesign® to crash! No validations checks are performed of the barcodes. Only EAN-13 are checked for validity (from v4.1.6 R25001).

The function is based on "Barcode Writer in Pure PostScript" by Terry Burton with the following legal notes:

Layout rules to create the code, see here for a complete list of available options. Additional code specific options you will find near the code descriptions..

The list is preassigned by the word "includetext". If you wish to suppress texts beside the code, please add the key suppresstext to your options.

One option value may contain any (blank-delimited) number of values you want. And you may define any number of option keys to - its values are (again blank-delimited) simply added to the current list of options.

"filetype", "..."

Not for comet_pdf. IDML-save embeding of barcode. Following values are supported:

"ps" : The link to the image file is embeded into the frame rather then its content. After that, the Postscript file is removed, but the "Embedded" entry inside the Link panel still remains.

"jpg", "tif", "gif" : The content of the image file is embeded directly into the frame. No new entries will appear in the Link panel but of course, the image now has a fix resolution (That is taken from the option resolution).

"filepath", "..."

Not for comet_pdf. Complete path to an output file. The code is written to the given path and the image is then linked to the given frame. If an image resolution is needed, it is taken from the option resolution. The following image formats are supported:

  "ps", "jpg", "tif", "gif"

"resolution", float

Not for comet_pdf Resolution for GIF/TIF/JPG images, ignored in case of Postscript.

QR codes getting bigger the more data they contain. Strings up to 2953 bytes (not letters!) are encodeable. To get a unique size of QR codes, QR codes may have a version) in the range of 1-40. QR codes of the same version having the same size always. To calculate the size in modules use the following formula:

Size of square = 17 + (Version * 4) modules

The modules created by image::barcode are 2 pts wide by default, so a version 1 QR code is 42 pts wide.

QR codes may have an error correction, see parameter eclevel. Error correction may reduce the number of bytes to encode. See the following tables for the maximum number of bytes to encode:
