We have seen 72 in this answer and 96 in this answer being suggested as the default density of an image, but which one? what if mine is different? So I decided to dig a little deeper and solve that problem as it seemed to be a side effect of this approach and I think it has to do with the original density or dpi. I was getting "low poly" curves using the general approach of increasing the density. Os.remove(os.path.join(tempPath, fileNameRoot + '.svg')) Os.remove(os.path.join(tempPath, fileNameRoot + '.jpg')) Jpg = open(os.path.join(tempPath, fileNameRoot + '.jpg'), 'rb').read() WriteToFile(os.path.join(tempPath, fileNameRoot + '.svg'), xmldoc.toxml())Įxecute('convert -background "%s" %s %s' % (backgroundColor, os.path.join(tempPath, fileNameRoot + '.svg'), os.path.join(tempPath, fileNameRoot + '.jpg'))) Xmldoc.getElementsByTagName("svg").attributes.value = '%spx' % newHeight Xmldoc.getElementsByTagName("svg").attributes.value = '%spx' % newWidth NewHeight = int(newWidth / width * height)
Height = float(xmldoc.getElementsByTagName("svg").('px')) Width = float(xmldoc.getElementsByTagName("svg").('px')) TempPath = os.path.join(self.rootFolder, 'data')įileNameRoot = 'temp_' + str(image.getID()) Here's my Python code, a function that will return the JPG file's content: import gzip, re, osįrom ynlib.files import ReadFromFile, WriteToFileįrom import parse, parseStringĭef SVGToJPGInMemory(svgPath, newWidth, backgroundColor): I've solved this issue through changing the width and height attributes of the tag to match my intended output size and then converting it using ImageMagick. Magick -density "%" button.svg button3.png In ImageMagick 7, you can do the computation in-line as follows: magick -density "%" button.svg button3.png So you can compute the needed density in proportion to the ratios of the dimensions and the densities. The input is 50 at default density of 96 (older versions of Inkscape may be using 92). Here is a small 50x50 button when rendered at the default density of 96: convert button.svg button1.png There is no "magic" parameter that will do what you want.īut, one can compute very simply the exact density needed to render the output. If Inkscape is installed on the system, ImageMagick will use it automatically. RSVG is a delegate that needs to be installed with ImageMagick. In ImageMagick, one gets a better SVG rendering if one uses Inkscape or RSVG with ImageMagick than its own internal MSVG/XML rendered.
