SpectrumKit not working in the case when you pass parameter with screenshot image but working fine with actual image. size(720,720), quality 80.

+(NSData*)spectrumData:(UIImage *)image size:(CGSize)size quality:(CGFloat)quality {
FSPEncodeRequirement *encodeRequirement =
[FSPEncodeRequirement encodeRequirementWithFormat:FSPEncodedImageFormat.jpeg
mode:FSPEncodeRequirementModeLossy
quality:quality];
FSPTransformations *transformations = [FSPTransformations new];
transformations.resizeRequirement =
[[FSPResizeRequirement alloc] initWithMode:FSPResizeRequirementModeExactOrSmaller
targetSize:size];
FSPConfiguration * configuration = [[FSPConfiguration alloc]init];
FSPEncodeOptions *options =
[FSPEncodeOptions encodeOptionsWithEncodeRequirement:encodeRequirement
transformations:transformations

configuration:configuration

NSError *error;
FSPSpectrum *spectrum = [[FSPSpectrum alloc] initWithPlugins:@[[FSPJpegPlugin new]]

FSPResultData *result = [spectrum encodeImage:image options:options error:&error];
return result.data;
}

Hi @08031992,

Could attach an actual image where this is not working?

@08031992 I can't repro the issue unless you share the image you're trying to encode.

I can see you're getting an error there, so it might be useful to also share the exact error details.
