What are the advantages and disadvantages of using Wordpress and doing it from scratch? [closed] ___ ___ erkimt EDGE can not copy large images using JS / from a canvas? ______ qstntxt ___

I have the following code, which copies pieces of the image "smoothchartshowAnalisysCopy" (500px X 250px) to the larger image (32172px X 250px).

%pre%

It works perfectly with IE, Firefox, Chrome, Safari and Vivaldi, except with MS Edge . MS Edge only copies the pieces of the image from the beginning to the position of 14000px .

In positions greater than 14000px , there is not even an error, but nothing is copied.

I did not find anything in the Microsoft documentation, or anything relevant to Google.

Here is the code solution:

Adjustment according to your needs:

this.context = FacesContext.getCurrentInstance();
this.response = (HttpServletResponse) context.getExternalContext().getResponse();

String caminho;
Map<String, Object> parametros = new HashMap<>();
baos = new ByteArrayOutputStream();
try {
if ("nao".equals(relatorio.getGeral()) && "periodo".equals(relatorio.getTipoDeRelatorio())) {

caminho = Faces.getRealPath("/reports/vendas/vendas.jasper");

parametros.put("Id_Cliente_Venda", relatorio.getCliente().getCodigo());
parametros.put("data_inicio", relatorio.getDataInicial());
parametros.put("data_fim", relatorio.getDataFinal());
parametros.put("CodEmpresa", autenticacaoBean.getUsuario().getEmpresa().getCodigo());

//JasperReport report = (JasperReport) JRLoader.loadObject(caminho);
JasperPrint print = JasperFillManager.fillReport(caminho, parametros, conexao);
JasperExportManager.exportReportToPdfStream(print, baos);

response.reset();
response.setContentType("application/pdf");
response.setContentLength(baos.size());
response.setHeader("Content-disposition", "inline; filename=relatorio.pdf");
response.getOutputStream().write(baos.toByteArray());
response.getOutputStream().flush();
response.getOutputStream().close();

context.responseComplete();
