![]() ![]() I am attaching here an original low-resolution TIFF image and the PDF file I could convert it to using the XnConvert (I cannot attach a CSV here, so I just created a PDF from the CSV I got with XnConvert). To better work with this data, I need to convert the CSV into another TIFF, which I presume will have a higher resolution than the one I got from the machine (with a much lower size). I exported a low-resolution image as TIFF and the high-resolution data, only available as a CSV file with the values of the pixels that represent that map. The image is its chemical composition in the form of a map. The CSV file was created by a scanning electron microscope that generated an image from a rock sample. ![]() Sorry, it's hard for me to explain because I've never worked with these conversions before. LibreOffice Calc can export to PNG (or JPEG) format, but I haven't found a way of exporting only a selection: from memory of a previous test involving exporting a selection to CSV, I think MS Excel might well be able to do that. I don't know how many files you have to convert, possibly quite a lot I imagine, but I would expect you to possibly be able to convert selected cells in Excel to a PDF file, as you have possibly saved a selection of cells to CSV?Īlternatively, could you use screenshots to create the image files you need? My thinking was that if you could convert the CSV files to PDF, you would then have a format that XnConvert could read when you set a suitable DPI value in the settings.īut how would you want the output, if XnConvert could read the ps or prm format files you have, and mightn't you be able get that result using PDF files? Its 'XnConvert' rather than 'XnConverter'. And XnConverter is not reading them, so I cannot convert the csv into images. The only match I found between my csv file and XnConverter is ps or prn formats. Yes, XnConvert is reading PDF files, but since I have a spreadsheet with thousands of numbers, converting to PDF is not really what I need. ![]()
