I am inserting an image in the crystal report by dragging a field of type picture from the database fields. The image is inserted as a blob field with a default (original) size even though in the database the image can have different sizes. The problem is that the image does not preserve its original size. Is there a way how specify the original size of the image in crystal reports?
Crystal report will not auto- re-size the image. So better to set the original size in Crystal report
try this code in c#:
CRAXDRT.Report report1 = new CRAXDRT.Report();
CRAXDRT.Application app = new CRAXDRT.Application();
report1 = app.OpenReport("YorReport.rpt", OpenReportMethod.OpenReportByDefault);
for (int i = 1; i < report1.Sections.Count + 1; i++)
{
for (int j = 1; j < report1.Sections[i].ReportObjects.Count + 1; j++)
{
try
{
CRAXDRT.BlobFieldObject t1 = (CRAXDRT.BlobFieldObject)report1.Sections[i].ReportObjects[j];
if (t1.Name == "YourBlobFieldName")
{
t1.Height = 200;
t1.Width = 200;
}
}
catch (Exception) { }
}
}
Check the Can Grow checkbox for the BLOB field.
That will auto size the field by image's original size.

I have following code to create a single pdf with 2 columns and 4 rows. Every cell contains an image.
int labelCount = x;
int columns = 2;
int labelsPerPage = 8;
int rows = labelCount/columns;
int resto = labelCount%columns;
if(resto>0) rows++;
String dest = "path_to_pdf_file";
PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdfDoc);
doc.setMargins(0, 0, 0, 0);
Table table = new Table(UnitValue.createPercentArray(columns)).useAllAvailableWidth();
Integer iCount = 0;
for (int i = 1; i <= rows; i++) {
for (int y = 1; y <= columns; y++) {
if(iCount<labelCount) {
String fileName = "name_of_image";
Cell cell = new Cell();
cell.add(new com.itextpdf.layout.element.Image(ImageDataFactory.create("full_path_to_image")).setAutoScale(true));
cell.setBorder(Border.NO_BORDER);
table.addCell(cell);
iCount++;
if(iCount==labelsPerPage-1) {
doc.add(new AreaBreak(AreaBreakType.NEXT_PAGE));
}
}
}
}
doc.add(table);
doc.close();
If number of labels is bigger than defined limit (8 per page), I want a new page to be created with the following labels.
In my code I used
doc.add(new AreaBreak(AreaBreakType.NEXT_PAGE));
but it generate (I don't know why) a blank page at the beginning. In the second page there are labels.
Which is the right way to add a new page dynamically and put remaining content into it?
Thanks
Essentially in your code you add AreaBreak to the document before you add the table, that's why the blank page is inserted before the table. iText 7 does not allow you to insert page breaks within tables at this point.
To achieve the desired result you need to flush the existing table to the document before moving on to the next page, and create a new table for the next page. Essentially you will be adding a bunch of tables separated with AreaBreak.
The pseudocode which does not require a lot of modifications to your code could look as follows:
Table table = new Table();
for (...) {
// populate table
if ("it's time to insert a page break") {
doc.add(table);
doc.add(new AreaBreak(AreaBreakType.NEXT_PAGE));
table = new Table(); // create new table
}
}
doc.add(table);
I'm developing a PowerPoint add-in with the feature to upload a presentation to the web server. I have a presentation with 100MB exact size. I used the guidelines for using GetFileAsync in Office docs. It is working for small presentation files. But the add-in message of not responding when I select largely presentation file. I did break point to the code and I found out that the cause of not responding is in js due to the large array slices. There is no problem with getting the slices of a large file. But the problem in when slices array concat to be one array.
Here's the code came from Office docs where the issue occurred.
function onGotAllSlices(docdataSlices) {
var docdata = [];
for (var i = 0; i < docdataSlices.length; i++) {
docdata = docdata.concat(docdataSlices[i]);
}
var fileContent = new String();
for (var j = 0; j < docdata.length; j++) {
fileContent += String.fromCharCode(docdata[j]);
}
// Now all the file content is stored in 'fileContent' variable,
// you can do something with it, such as print, fax...
}
I don't know if it is a bug or issue on the part of Office Add-in. I hope someone helps me.
Thanks in advance.
UPDATES:
I simplify the given function like this:
function onGotAllSlices(docdataSlices) {
var fileContent = new String();
for(var i = 0; i < docdataSlices.length; i++) {
var docdata = docdataSlides[i];
for(var j = 0; j < docdata.length; j++) {
fileContent += String.fromCharCode(docdata[j]);
}
}
var base64String = window.btoa(fileContent);
}
So far, there is no 'out of memory' issue at all. But there is another issue with error message of '8007000e. “Not enough storage is available to complete this operation”' when the fileContent convert in base64String.
This looks like it's a performance problem. Have you checked How to extend an existing JavaScript array with another array, without creating a new array? ? .concat will create a new array from the previous two ones, which you're re-assigning. Perhaps there's a better way of doing this?
I'm doing a project where I'm outputting the frequencies from real time mic input through fft to a txt doc and then retrieving (or trying to retrieve) them to a list of 4 frequencies. My list array is turning out empty, ie the console prints [] and no numbers in them. Pl tell me what is wrong with the logic/code. This is within the void draw()
for (int i = 0; i<fft.specSize(); i++) {
float freq = fft.getFreq(i);
int freqint = (int) freq;
//println(freqint);
output.println(freqint);}
Scanner input = new Scanner("...\\list.txt");
while (input.hasNextInt()) {
list.get(input.nextInt(4));
}
println(list);
input.close();
Split your taks into subtasks:
get FFT data (and 4 frequencies)
Save/Load float values to disk
Put the 1 and 2 together
It looks like you already have the first part done.
It's unclear what the 4 frequencies are, but you can figure that out on your own.
The part that is confusing is that you call the get FFT data once then try to save it straight to disk. I'm not 100% that's what you mean to do.
Double check if you need to save few samples/seconds worth of FFT data first.
I would imagine a more generic scenario like this:
load previously saved FFT data (if any)
process FFT data (for as long as needed - might need a start/stop boolean) and append
save current FFT data
Moving on to saving and loading data.
You've got a few of options build into Processing for storing data:
Strings via saveStrings()/loadStrings()
CSV Table via saveTable()/loadTable()/Table
JSON via JSONObject/JSONArray and available load/save functions
XML
I recommend reading Daniel Shiffman's Data Tutorial
Dealing with saving/loading floating point values to disk alone,
here's a basic proof of concept snippet using Strings:
int fftSpecSize = 10;//this will be fft.specSize() in your case
String values = "";
for(int i = 0 ; i < fftSpecSize; i++){
//random(1) is a placeholder for fft.getFreq(i);
values += random(1);
//if it's not the last value, add a separator character (in this case space)
if(i < fftSpecSize-1){
values += " ";
}
}
println("values to save:");
println(values);
println();
//save data
saveStrings("fftSingleRead.txt",values.split(" "));
//load data
String[] readValues = loadStrings("fftSingleRead.txt");
//print raw loaded data
println("readValues from .txt file:");
println(readValues);
println();
//parse values:
for(int i = 0 ; i < readValues.length; i++){
float value = float(readValues[i]);
println("readValues[",i,"] = ",value);
}
additionally here's a Table example too:
Table fftValues;
int specSize = 10;
//create a new table
fftValues = new Table();
//add columns - one per FFT bin
for(int i = 0 ; i < specSize; i++){
fftValues.addColumn();
}
//add some data, a row per reading
//create a new row
TableRow newRow = fftValues.addRow();
//add each fft value to the row
for(int fftCount = 0 ; fftCount < specSize; fftCount++){
//placeholder for newRow.setFloat(fftCount,fft.getFreq(fftCount));
newRow.setFloat(fftCount,random(1));
}
//add the row to the table
fftValues.addRow(newRow);
//save to disk
saveTable(fftValues,"fftValues.csv","csv");
//load from disk
Table readValues = loadTable("fftValues.csv","csv");
//access the data that has been saved in the table
for(int rowCount = 0; rowCount < readValues.getRowCount(); rowCount++){
TableRow currentRow = readValues.getRow(rowCount);
print("row[",rowCount,"] = ");
for(int columnCount = 0; columnCount < currentRow.getColumnCount(); columnCount++){
float value = currentRow.getFloat(columnCount);
print(value);
if(columnCount < currentRow.getColumnCount() - 1){
print(",");
}
}
println();
}
Try the code, see the output, read the comments, read the reference, tweak/retry/understand and adapt to your problem.
I'm trying to make a script that will resize the images in a google doc. What I have is:
var imgs = currentDoc.getImages();
for (var i = 1; i < imgs.length; i++)
{
cell = row.insertTableCell(1);
imgNew = imgs[i].setWidth(365);
cell.insertImage(1, imgNew.getBlob());
}
The image gets inserted correctly but the size does not change regardless of what I set the width to. Since the image is going into a cell (width=370), is it possible to just make the image take up 100% of the width and scale the height proportionally? If not I can deal with manually setting the number of pixels but that is not working either. Any ideas?
The problem is that the image size should be changed after it is inserted to a table. The following code works correctly
function test() {
var doc = DocumentApp.openById('here_is_doc_id');
var imgs = doc.getImages();
var table = doc.getTables()[0];
for (var i = 0; i < imgs.length; i++) {
var row = table.appendTableRow();
var cell = row.insertTableCell(0);
var imgNew = imgs[i].copy();
cell.insertImage(0, imgNew);
imgNew.setWidth(365);
}
}
Please mention, that array indexes, cells numbers, etc. start from 0 and not 1.
Just as an FYI, you don't need to call getBlob()... anything that has a getBlob() can be passed in directly wherever a Blob is needed.
Have you tried:
imgs[i].attr('width', '370');
Or try assigning a class that has width: 100%
If I want to change the color of circles in scatter chart based on a field not being used in the chart, then how do i use that column in script. I mean how can i get the that data...for example
If (row[v_count])>2
fill red color...
The exact code is below
function beforeDrawDataPoint(dph, fill, icsc)
{
//Fill implements Fill interface
//ImageImpl
//ColorDefinitionImpl
//GradientImpl
//MultipleFillImpl
//EmbeddedImageImpl
//PatternImageImpl
importPackage( Packages.org.eclipse.birt.chart.model.attribute.impl );
val = dph.getOrthogonalValue();
if( fill.getClass().isAssignableFrom(ColorDefinitionImpl)){
if (row[v_count]>2){
fill.set(255, 0, 0);
}
}
}
but i dont know do i get that v_count column in the script. is there some function to get that column ?
I mean if we are making some calculations based on a column from databinding columns..that is not being used in x or y axis, then how do we access that column in the script..is there some kind of function for that.. I tried row["v_count"], but it is not working.

You could use "persistent global variables". In any place of your report you can write the following to store and load a global variable. Note that you cannot store Integers but only Strings (but after loading you can cast your Strings back to other types). You could store the Value of your column in the Script of an invisible data field located above your chart, so inside your chart you can read the value.
//store a value
reportContext.setPersistentGlobalVariable("varName", "value");
//load the value
var load = reportContext.getPersistentGlobalVariable("varName");
I spend my day look but I did not find the solution, this is my colleague who give me :)
So I share.
in my example I had to create a vertical marker for every new year
function beforeGeneration(chart, icsc)
{
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);
importPackage(Packages.org.eclipse.birt.chart.model.data.impl);
importPackage(Packages.org.eclipse.birt.chart.model.attribute);
importPackage(Packages.org.eclipse.birt.chart.model.attribute.impl);
var chart = icsc.getChartInstance();
var yAxis = chart.getBaseAxes()[0];
//get date series for my case
series = yAxis.getRuntimeSeries();
// but if you have multiple series ... (for exemple xaxis)
for (i = 0; i < series.length; i++){
var values = series[i].getDataSet().getValues();
for (j = 0; j < values.length; j++){
if(j > 1){
var date1 = values[j-1];
var date2 = values[j];
if(date1.getYear() < date2.getYear()){
min_ml = MarkerLineImpl.create(yAxis, NumberDataElementImpl.create(j));
min_ml.getLabel().getCaption().setValue("Nouveau boitier");
min_ml.getLineAttributes().getColor().set(255,0,0);
}
}
}
}
}
